摘要： 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.
摘要翻译：当蜗轮由于夹杂异物而相对于物体夹持检测板旋转时，分别形成在蜗轮和物体夹持检测板的相对表面上的突出物彼此接合。通过接合，物体夹持检测板轴向移动。此时，物体夹持检测板轴向移动而不旋转，因此物体夹持检测板与物体夹持检测开关的可动片接触而不旋转。因此，当物体夹持检测板和物体夹持检测开关彼此接触时，不会发生由旋转引起的磨损。因此，防止了由于磨损导致的物体夹持检测精度的劣化。
