ABSTRACT:
A motor is provided with a speed reducer. The motor includes a rotatable motor shaft having an end face and a threaded portion. The speed reducer includes a gear for communicating with the threaded portion of the motor shaft. A speed reduction case encloses at least a part of the speed reducer and includes a thrust receiving portion facing the end face of the motor shaft. An end spacer is disposed between the thrust receiving portion of the speed reduction case and the end face of the motor shaft. The end spacer includes a press-fitting portion secured at the thrust receiving portion of the speed reduction case to prevent the end spacer from rotating relative to the speed reduction case. The end spacer also includes a protrusion. A thrust force applied to the motor shaft presses the end face of the motor shaft to the protrusion of the end spacer to brake the rotation of the motor shaft by friction.
