ABSTRACT:
There is provided a mobile member position detection apparatus in which not only high-accuracy detection of a position of a window glass or the like of a power window apparatus but also setting of an initial position being free from cumbersome adjustment can be realized with a simple structure at low cost. In this position detection apparatus, a transmission plate and a cam plate are rotated together with the rotating shaft of a window regulator, and a limit switch is rendered conductive to detect a predetermined rotational position. Thereafter, when the rotating shaft is rotated, the intermeshing state between a tooth portion and a tooth portion obtained by a wave washer is released, and rotation of the rotating shaft is not transmitted to the cam plate. Therefore, when the rotating shaft (drive motor) is sufficiently rotated during an incorporating operation, an initial state wherein a projecting portion is brought into contact with a stopper to render the limit switch conductive is automatically set.
