PROBLEM TO BE SOLVED: To inhibit leakage of a cooling medium to a housing of a rotary electric machine structure.SOLUTION: In a tray 11 attached to an inverter part 5 of a housing 1, inverter components are attached to a motor part 3 side lower surface. One end of a tray coolant passage 17 provided on an upper surface of the tray 11 communicates with a housing coolant passage 23 of a motor part 3 through an outlet connecting hose 19 and a boss part coolant passage 21a in a boss part 21. The other end of the tray coolant passage 17 opens to the outside through an inlet connecting hose 25. A seal member provided in a joint part between the tray 11 and the inverter part 5 is provided between an area of the tray 11, in which the inverter components are positioned, and the outlet connecting hose 19 and the inlet connecting hose 25.SELECTED DRAWING: Figure 1 |
