Abstract
A bearing unit for a drive motor, which is installed between a motor housing and a rotating shaft, includes: a bearing having two or more support bumps formed on the outer circumferential surface of an outer ring, and installed between the front or rear of the rotating shaft and the motor housing so as to rotatably support the rotating shaft with respect to the motor housing; and a bearing cover assembled to the motor housing, having a circular stepped surface formed on one surface such that an outer ring of the bearing is fitted to the stepped surface and supported in an axial direction. In particular, a support portion is formed on the stepped surface and is in contact with the support bumps so as to fix the outer ring in a rotation direction.
