20120198770 | WINDOW REGULATOR DEVICE - When a worm wheel rotates relative to an object pinching detection plate due to pinching of a foreign object, protruding pieces respectively formed on opposed surfaces of the worm wheel and the object pinching detection plate engage with each other. Through the engagement, the object pinching detection plate axially moves. At this time, the object pinching detection plate axially moves without rotation, and hence the object pinching detection plate is brought into contact with a movable piece of an object pinching detection switch without rotation. Therefore, wear due to rotation does not occur when the object pinching detection plate and the object pinching detection switch are brought into contact with each other. Thus, deterioration in object pinching detection accuracy due to the wear is prevented. | 08-09-2012 |
