Abstract
In the rotary electric machine according to the present invention, a first O-ring 13a is mounted between a pair of position regulating members 12 that are press-fitted onto and held in a vicinity of a second axial end of an outer circumferential surface of a stator core housing portion 10a so as to be spaced apart in an axial direction, and is pressed and held between the stator core housing portion 10a and a cylindrical portion 16, and a second O-ring 13b is mounted into an O-ring housing groove 11 that is recessed into an outer circumferential surface of a frame mounting portion 10b, and is pressed and held between the frame mounting portion 10b and the cylindrical portion 16, such that a coolant channel 22 is formed between the frame 10 and the cylindrical portion 16.
