<P>PROBLEM TO BE SOLVED: To stabilize the discharge direction of a coolant discharged from a discharge hole provided on a coolant pipe side wall and inhibit the increase of the weight in a coolant pipe introducing the coolant to a predetermined position of a rotary electric machine. <P>SOLUTION: A discharge hole 32, which discharges a coolant toward a predetermined portion of a rotary electric machine 12, is provided on a side wall 28 of a cylindrical coolant pipe 26. The side wall 28 is thickly formed around the discharge hole 32. This structure inhibits influences of a velocity component even if the velocity of the coolant flowing in the coolant pipe 26 is increased and stabilizes the discharge direction. Further, since the side wall 28 is thickly formed only around the discharge hole 32, the weight increase is inhibited, compared to a case that the entire portion is thickly formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
