ABSTRACT:
A position detector for a motor includes a pulse plate, having a fitting hole, for generating pulse signal, a connection shaft having protrusion portions and a washer having a connection hole. Each protrusion portion of the connection shaft is inserted into the fitting hole of the pulse plate and further inserted into the connection hole of the washer, and top ends of each protrusion portions are fastened to the washer. Thus, even if a rotational torque transmitted from the connection shaft to the pulse plate becomes large, the rotational force of the connection shaft can be accurately transmitted to prevent only the connection shaft from idling without releasing the connection between the connection shaft and the pulse plate.
