Abstract: A rotating electrical machine includes an annular coil connection body provided coaxially with a stator. The coil connection body has, in a groove provided on a holder, an overhang portion for restricting an axial-direction movement of a terminal, and a positioning projection for restricting a radial-direction movement of the terminal. The positioning projection positions the terminal such that a part of the terminal overlaps the overhang portion in the axial direction. In this structure, when the terminal moves in a direction from a terminal holding portion toward a groove opening, the terminal comes into contact with a side surface of the overhang portion, whereby lifting and coming-off of the terminal can be prevented.

Abstract: A control device-integrated rotary electric machine that has a light weight and a small radial-direction dimension. A cylindrical member is provided between a stator formed by stacking electromagnetic steel sheets and a frame retaining the stator, such that the cylindrical member is in a press-fitted state against the stator and the frame. The cylindrical member has a flange portion at one end thereof, and the flange portion is fixed by being held between the frame and a heat sink which is a member composing a control device.
