PROBLEM TO BE SOLVED: To provide a rotary electric machine which expands a heat transfer path between a stator and a motor case and achieves improvement of cooling performance.SOLUTION: A rotary electric machine is provided with a first heat conduction member 41 and a second heat conduction member 42 which are disposed at internal and external sides forming double layers as heat conduction members 4 thermally contacting with a stator 2 and a motor case 1. The first heat conduction member 41 includes: a first body part 41a contacting with the stator 2; and first plate spring parts 41b which are erected from the first body part 41a in an outer diameter direction and elastically contact with the motor case 1. The second heat conduction member 42 includes: a second body part 42a contacting with the motor case 1; and second plate spring parts 42b which are erected from the second body part 42a in an inner diameter direction and elastically contact with the stator 2. First opening parts 41d, each of which allows the second plate spring part 42b to penetrate therethrough in a radial direction, are provided in the first body part 41a. Second opening parts 42d, each of which allows the first plate spring part 41b to penetrate therethrough in the radial direction, are provided in the second body part 42a.SELECTED DRAWING: Figure 2 |
