Abstract
An actuator is provided with a motor having a worm, a worm wheel in engagement with said worm and having a pinion-engaging part, a pinion having a worm wheel-engaging part and a rotational axis offset from the rotational axis of the worm wheel, a sector wheel having an output arm and meshing with the pinion, a contact holder, and a positional switch for switching contacts according to the engagement of the contact holder with the sector wheel. The sector wheel is sited at its starting position in a state in which the pinion-engaging part is engaged with the worm wheel-engaging part at a position opposite to the rotational axis of the pinion relative to the rotational axis of the worm wheel. The actuator is compact and uses the motor power very effectively.
