[Claims for Utility Model Registration] A stator, a rotor disposed inside the stator, a cylindrical yoke surrounding the stator, an end cover that closes both ends of the yoke, and a rotor disposed inside the stator. In a rotating electric machine including a brush holding plate fixed to the inside of one end cover that closes one end, and a brush fixed to the brush holding plate, the inner diameter of the inner circumference near one end of the yoke is enlarged. A caulked portion is formed, and a spacer receiving surface facing the opening direction of one end of the yoke is formed at the boundary between the caulked portion and another portion, and an annular portion surrounding the brush holding plate and a spacer receiving surface of the annular portion are formed. The brush has a plate receiving part that projects radially inward from the inner peripheral part and a collar part that projects radially outward from the outer peripheral part of the annular part, and the brush is provided between the collar part and the plate receiving part. A spacer is provided with a step having a depth slightly greater than the thickness of the holding plate, and the brush holding plate is received by the spacer while being inserted inside the annular portion of the spacer, and the brush holding plate The spacer that received the spacer is fitted onto the inner periphery of the caulked part with the collar part in contact with the spacer receiving surface on the inner periphery of one end of the yoke, and the end cover is received by the spacer. It has a flange portion that faces a portion near the outer periphery of the brush holding plate and the flange portion of the spacer, the flange portion is fitted to the inner periphery of the yoke caulking portion, and the yoke caulking portion is the flange portion of the yoke. A rotating electrical machine characterized by a swaged end cover on the flange side.
