Abstract

In a position detector, a ring gear rotates with a motor output shaft and a specified rotation position is detected by a move contact and fixed contacts. When the output shaft rotates thereafter, holding a carrier by a wave washer is released and the transmission of rotation of the output shaft to the ring gear is dropped. Therefore, by rotating the output shaft sufficiently at the time of assembling, an initial state, in which a protrusion section abuts a protrusion and the move contact contacts the fixed contact, is set automatically.
