20080203833 | BRUSH HOLDER - A brush holder includes a base member and a retaining member mounted on the base member. The retaining member includes a first brush retaining portion and a first coil retaining portion. A first choke coil is electrically connected to a first brush. The first choke coil includes a first coil terminal extending to the outside of the first coil retaining portion. The base member includes a connector portion, a first conductive member, and a first coil terminal support portion. The first conductive member extends from the connector portion and is electrically connected to the first coil terminal at a first connecting portion. The first coil terminal support portion supports the first coil terminal between the first connecting portion and the first coil retaining portion. | 08-28-2008 |
20080203836 | DIRECT CURRENT MOTOR - A gear housing accommodates a worm shaft. A brush holder includes a base member and a retaining member loosely fitted to the base member. The base member is located between the gear housing and the retaining member. The retaining member retains a first brush and a second brush. The retaining member has a pair of positioning poles, and the gear housing has a pair of positioning projections. The positioning poles and the positioning projections are engaged with each other so as to prevent the retaining member from being moved in a direction perpendicular to the axial direction of the rotary shaft. | 08-28-2008 |
20100176696 | CONTROL CIRCUIT MEMBER AND MOTOR - A control circuit member provided in a motor is disclosed. The motor includes a motor main body having a rotary shaft and a gear housing integrated with the motor main body. The control circuit member includes a circuit substrate on which a rotation detecting element is mounted and a substrate support member. The circuit substrate is accommodated in a circuit accommodating portion in the gear housing. The substrate support member supports the circuit substrate inside the circuit accommodating portion. The control circuit member is configured to be insertable into the circuit accommodating portion along the axial direction of the rotary shaft. The circuit substrate is configured to be arrangeable inside the circuit accommodating portion while being inclined with respect to the axial direction of the rotary shaft, so as to cause the rotation detecting element to approach the detector magnet. | 07-15-2010 |
20120098367 | CLUTCH AND MOTOR - A clutch including a drive shaft, drive side rotation body, driven shaft, driven side rotation body, clutch housing, and lock member is disclosed. During non-rotation of the drive side rotation body, when the driven side rotation body is rotated, the lock member is pushed by the driven side rotation body and moved outward in a radial direction thereby bringing the contact portion into contact with the inner circumferential surface of the clutch housing. During rotation of the drive side rotation body, the drive side rotation body pushes a drive side cam surface in the rotation direction, and the drive side cam surface acts to move the lock member inward in the radial direction and push the lock member against the driven side rotation body. Thus, the lock member is sandwiched between the drive side rotation body and the driven side rotation body thereby coupling the drive side rotation body and the driven side rotation body with the lock member to be integrally rotatable. | 04-26-2012 |
20120161559 | MOTOR - A motor includes a motor portion and a speed reducing portion. In the motor portion, a brush holder that holds a feeder brush for feeding electric power to a commutator is arranged at an opening of a yoke. The speed reducing portion has a speed reducing mechanism, which is arranged in a gear housing. The speed reducing mechanism outputs drive force produced by a rotary shaft of the motor portion with the rotating speed of the rotary shaft reduced by the speed reducing mechanism. A brush holder includes a support pillar projecting toward the gear housing and an urging member that urges the feeder brush against the commutator. A positioning portion for positioning the brush holder with respect to the gear housing in a direction perpendicular to the axial direction is formed at a distal end portion of the support pillar. | 06-28-2012 |
20120161560 | MOTOR - A motor includes a motor unit, a deceleration unit, and a connector unit. The motor unit outputs rotational drive force and includes a yoke housing, a commutator, a power supply brush, a conductive member, and a brush holder. The yoke housing has an open end in an axial direction. The conductive member is electrically connected to the power supply brush. The brush holder is arranged in the open end to hold the commutator, the power supply brush, and the conductive member. The deceleration unit includes a gear housing coupled to the open end. The connector unit is coupled to the gear housing and including a connection terminal electrically connected to the conductive member. The commutator and the power supply brush are arranged outside the yoke housing. The conductive member and the yoke housing are arranged on opposite sides of the commutator. | 06-28-2012 |
20120194020 | MOTOR - A brush holder is provided in a metal yoke. The brush holder holds feeder brushes for supplying power to a commutator. The commutator and the feeder brushes are arranged outside the yoke housing as seen in a direction orthogonal to the axis of the yoke. As seen in the axial direction, proximal ends of the feeder brushes are arranged outside the inner circumferential surface of the yoke. | 08-02-2012 |
20130285492 | MOTOR - The axial direction of a worm wheel is defined as a motor short-transverse direction, and a plane orthogonal to the motor short-transverse direction is defined as a motor flat plane. An imaginary plane contacting a first end of a sensor magnet in a motor short-transverse direction and parallel with the flat plane is defined as a first imaginary plane. An imaginary plane contacting a second end of the sensor magnet in the motor short-transverse direction and parallel with the flat plane is defined as a second imaginary plane. A control circuit board is provided with a rotation detecting element that detects rotation of the rotary shaft of the motor. The control circuit board is arranged to be parallel with or inclined relative to the flat plane, and is provided between the first and second imaginary planes. | 10-31-2013 |
20140132095 | MOTOR - A motor includes a motor unit, a gear housing coupled to the motor unit, and a connector module including a connector housing coupled to the gear housing. The motor unit includes a rotation shaft and a power terminal. The gear housing accommodates a deceleration mechanism that outputs decelerated rotation of the rotation shaft. The connector terminal and the circuit substrate are fixed to the connector housing. The power terminal is connected to a socket of the connector terminal when coupling the connector housing to the gear housing. The connector terminal includes a fixed portion fixed to the connector housing, a substrate connecting portion connected to the circuit substrate, and a supported portion located closer to the socket than the substrate connecting portion. The connector housing includes a terminal supporting portion that supports the supported portion from the rear in the coupling direction. | 05-15-2014 |
