摘要:
A clutch mechanism and a worm wheel are disposed in such a manner as to be aligned or superposed on each other via a base plate held therebetween. A circular swollen portion is formed on the base plate in such a manner as to project from one side to another side of the base plate. The swollen portion is disposed in such a manner as to face the worm wheel, and a side of a field core of a clutch mechanism is accommodated within a dish-shaped recess formed on a rear side of the swollen portion.
