To provide a cooling pipe fixing structure which includes multiple pipes for supplying a refrigerant delivered from multiple pumps to a rotary electric machine from above and a bracket connecting the multiple pipes and achieves improvement of assemblability and prevention of refrigerant leakage.SOLUTION: A cooling pipe fixing structure 80 includes: a first pipe 28 and a second pipe 30 which supply oil delivered from a mechanical oil pump 42 and an electric oil pump 44 to a second rotary electric machine 20 from above; and a bracket 82 connecting the first pipe 28 to the second pipe 30. The respective pipes 28, 30 are fixed to an interior of a case body 22. In the second pipe 30 in which pressure fluctuation of the oil flowing therein is relatively small, an opening end 30b side tip part 30c connects with a rubber seal 84 provided at the case body 22. In the first pipe 28 in which pressure fluctuation of the oil flowing therein is relatively large, an opening end 28b side tip part 28c connects with an insertion hole 25 provided at the case body 22 by loose fitting.SELECTED DRAWING: Figure 3

    【課題】複数のポンプのそれぞれから送出される冷媒を回転電機の上方から供給する複数のパイプと、複数のパイプを接続するブラケットとを備え、組み付け性の向上と冷媒漏れの防止とを両立できる冷却パイプの固定構造を提供する。【解決手段】冷却パイプの固定構造80は、MOP42及びEOP44のそれぞれから送出されるオイルを第2回転電機20の上方から供給する第1パイプ28及び第2パイプ30と、第1パイプ28及び第2パイプ30を接続するブラケット82とを備え、各パイプ28,30をケース体22の内部に固定する。内部を流れるオイルの圧力変動が相対的に小さい第2パイプ30では、その開口端30b側の先端部30cがケース体22に設けたゴムシール84と接続する。内部を流れるオイルの圧力変動が相対的に大きい第1パイプ28では、その開口端28b側の先端部28cがケース体22に設けた挿入孔25と隙間嵌めにより接続する。【選択図】図3
