PROBLEM TO BE SOLVED: To obtain a motor with reduction gear that can prevent reverse rotation of a rotating shaft in the output side with a force from the side where the rotation is transferred and also maintains the high rotating transfer coefficient during the normal rotation. SOLUTION: In this motor with reduction gear, an output side worm is mounted to a motor output shaft 3 at a worm wheel 5 to which the rotation is transferred and a bearing device 10 is provided in the contact condition at the end surface of this motor shaft 3. The bearing device 10 is provided with the structure that a one-way clutch 12 and a rotor 11 engaged with this one-way clutch 12 are provided and this one-way clutch 12 restricts the rotating direction when a thrust load is not received from the motor output shaft 3. |
