Abstract
A rotary electric machine includes: a stator around which a coil is wound; a frame which fixes the stator; a rotor which faces the stator via a slight air gap; a shaft which is fixed to the rotor and is rotatably and removably supported via a bearing; and a bracket which supports the bearing inside a bearing box. The rotary electric machine includes: an insulating member which is mounted inside the bearing box of the bracket; a metal holder which is mounted inside the insulating member with a predetermined clearance with respect to an outer ring of the bearing, and supports the bearing; and a pressing body which is mounted between the side surface of the metal holder and the side surface of the outer ring of the bearing.
