Abstract
In a motor device, since the bearing support member mounted to the housing and supporting, from the axial direction, the another axial side of the ball bearing (outer race) includes the annular support part (annular flat surface) which supports, from the axial direction, the entire circumference of the another axial side of the ball bearing (outer race), tilting of the ball bearing with respect to the housing can be suppressed in the case where a lateral force acts on the rotating shaft. Therefore, it is possible to improve the fixing strength of the ball bearing to the housing, and thus suppress rattling of the speed reduction mechanism.
