PROBLEM TO BE SOLVED: To prevent loosening of a screw member by vibration.SOLUTION: The rotary electric machine of the embodiment comprises: a bracket side seat portion projecting radially from an outer peripheral surface of a bracket; a frame side seat portion in which bracket side seats are stacked from the axial direction; and a screw member for joining the bracket side seat portion and the frame side seat portion. On the bracket side seat portion, a contact portion which is in surface contact with the frame side seat portion on the outer peripheral side as compared with the contact point closest to the bracket among the outer peripheral surface of the rod portion of the screw member when viewed from the axial direction and a relief portion which is spaced apart from the frame side seat portion on the outer peripheral side are provided.SELECTED DRAWING: Figure 2 【課題】ネジ部材が振動で緩むことを防止する。【解決手段】実施例の回転電機は、ブラケットの外周面から径方向へ突出するブラケット側座部と、ブラケット側座部が軸方向から重ねられたフレーム側座部と、ブラケット側座部およびフレーム側座部間を接合するネジ部材を備えたものであり、ブラケット側座部には軸方向から見てネジ部材の棒部の外周面のうち最もブラケットに接近する接点に比べて外周側でフレーム側座部に面接触する接触部および同外周側でフレーム側座部から離間する逃げ部が設けられている。【選択図】図２
