Claims

[Claims for Utility Model Registration] (1) A motor with a speed reduction mechanism, characterized in that a one-way clutch is interposed in at least one of the bearings supporting the rotating shaft to prevent reverse rotation. (2) A bearing equipped with a one-way clutch is
Its outer periphery is formed into a spherical shape, and
A motor with a speed reduction mechanism according to claim 1, wherein the motor is prevented from rotating in the circumferential direction. (3) The motor with a speed reduction mechanism according to claim 1, wherein the one-way clutch is interposed in a bearing disposed at an end opposite to the speed reduction mechanism.
