ABSTRACT:
For a position detector of a motor actuator, two types of flanges are provided. Each flange has a movable contact, on which fixed sliding contacts slide to detect a predetermined rotational position of a motor when the flange is driven by the motor. Either one of the flanges is used in the position detector depending on the combination of motor rotation directions (forward/reverse) and doors (left/right). Thus, a single cover plate which accommodates the flange may be used for both doors irrespective of the motor rotation direction.
