Abstract
Provided is a rotating electric machine capable of preventing an outer race of a bearing from rotating because of a reduction in force for coupling a bearing housing portion and the outer race of the bearing. A resin case (24) uses thermal expansion to fill a clearance between the bearing housing portion and the outer race of a counter-driving side bearing. A hook (25) projecting inward in a radial direction is formed at least at one position on a circumferential edge portion of the resin case (24) on a side opposite to a rotor. The bearing housing portion includes a concave portion to which the hook (25) is to be locked, which is formed on a flange portion inside of which a shaft passes.

8. A rotating electric machine, comprising:
-
a shaft; a rotor fixed to the shaft; bearings for supporting the rotor, which are provided rotatably to the shaft on both sides of the rotor; and brackets comprising bearing housing portions into which the bearings are respectively press-fitted, the bearing being press-fitted into the bearing housing portion through a clearance filling member having a cylindrical shape therebetween, wherein the clearance filling member uses thermal expansion to fill a clearance between the bearing housing portion and an outer race of the bearing, which is generated by a difference in thermal expansion between the bearing housing portion and the outer race of the bearing due to heat generation at time of driving, the clearance filling member comprising a hook projecting inward in a radial direction and formed at least at one position on a circumferential edge portion thereof on a side opposite to the rotor, and wherein the bearing housing portion comprises a concave portion to which the hook is to be locked, the concave portion being formed on a flange portion inside of which the shaft passes. - View Dependent Claims (9, 10, 11, 12, 13, 14)
