One of the connecting portion of the movable transmission part and the connecting portion of the fixed transmission part is received in the other of the connecting portions with a single seal member disposed therebetween so that an internal space of the fixed transmission part and an internal space of the movable transmission part communicate with each other to thereby form a single hermetically-sealed space for holding therein a lubricating oil. | 11-26-2009 |
20110083328 | BUSH CUTTER - Driving power is transmitted to an output shaft, via driving and driven bevel gears, to a cutter blade. A gearbox supports the output shaft via first and second bearings. The second bearing is engaged by an engaging member to be prevented from axial movement, toward the blade, relative to the gearbox and supports the output shaft near the cutter blade. The output shaft is connected to the driven bevel gear such that it is prevented from rotation relative to the driven bevel gear but allowed to move axially. When the engaged state, by the engaging member, of the second bearing is canceled, the shaft is allowed to axially move toward the cutter blade until the shaft becomes rotatable relative to the driven bevel gear, at the same time of which a retaining stopper prevents the shaft from further axial movement. | 04-14-2011 |

At least one of opposing faces of the base housing and the elastic wall member on the working air chamber side thereof has a plurality of rib portions which extend from an inner circumferential side thereof towards an outer circumferential side thereof. A vibration damping device equipped with the pneumatic actuator is also disclosed. | 01-08-2009 |
20090038896 | Fluid filled type vibration damping device - A fluid filled type vibration damping device having an orifice passage formed in a partition member to connect a pressure receiving chamber and an equilibrium chamber, wherein a first end section of the orifice passage extends in along a plane of the partition member, and a communication hole is formed to bend at a right angle from the first end of the orifice passage and open towards the pressure receiving chamber to form a dead water region by orthogonal wall faces of a terminal end face and a bottom face of the orifice passage in a connecting corner section of the orifice passage with the communication hole. A shunt hole of smaller cross-sectional area than the orifice passage and the communication hole is formed in a bottom wall so that the pressure receiving chamber and the equilibrium chamber communicate through the shunt hole in the dead water region. | 02-12-2009 |
20110115258 | MOUNTING OF SUBFRAME - In a structure for mounting a subframe, located under a vehicle body, to the vehicle body via an elastic assembly, the elastic assembly includes: a first mounting member located under the vehicle body and over the subframe; a second mounting member located immediately above the first mounting member; and an elastic member disposed between the first and second mounting members. The first mounting member is mounted to the vehicle body, while the second mounting member is mounted to the subframe. | 05-19-2011 |
20110210230 | FLUID-FILLED TYPE VIBRATION DAMPING DEVICE - A fluid-filled type vibration damping device including a resin bracket provided on an outside peripheral face of a second mounting member.

20140248510 | DISSIMILAR-MATERIAL WELDED STRUCTURE AND WELDING METHOD THEREFOR - Friction stir welding is performed in the following manner. In the state in which a probe is rotated in a predetermined rotation direction, the probe is inserted into a flange of a rear sub frame, thereby starting friction stir welding to weld the flange of the rear sub frame and a flange of a front sub frame positioned on the inner side of the rear side of a vehicle. The probe is sequentially moved along the direction of arrow R1→arrow R2 (predetermined direction). When the probe reaches the end point of the direction indicated by arrow R2, the probe is inserted into the flange on the outer side across a protruding portion disposed between the flanges. Then, the probe is sequentially moved in the direction of arrow R4→arrow R5→arrow R6, which is opposite to the direction of arrow R1→arrow R2. | 09-04-2014 |
