Abstract
A motor includes a bearing and a bearing holder. The bearing is employed for rotatably supporting a motor shaft. The bearing holder is formed of a resin material and adapted to retain the bearing. Further, the bearing holder includes a cylindrical portion to which the bearing is press-fitted and a planar portion which is formed integrally with the cylindrical portion and is adapted to be arranged perpendicularly to the motor shaft. The cylindrical portion includes a first slit extending in an axial direction. The planar portion includes a second slit extending continuously with the first slit of the cylindrical portion.

A motor comprising:
- a bearing for rotatably supporting a motor shaft;
- and
- a bearing holder formed of a resin material and adapted to retain the bearing, the bearing holder including a cylindrical portion to which the bearing is press-fitted and a planar portion formed integrally with the cylindrical portion and adapted to be arranged perpendicularly to the motor shaft,
- wherein the cylindrical portion includes a first slit extending in an axial direction and the planar portion includes a second slit extending continuously with the first slit of the cylindrical portion, and said motor further comprising:
- a brush,
- wherein the planar portion of the bearing holder includes a brush accommodating portion for retaining the brush to be radially slidable, and the second slit of the planar portion is defined at the brush accommodating portion.
