Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cooling structure of a rotary electric machine for vehicle capable of efficiently cooling the inside of a casing while preventing foreign matter from entering inside the casing.SOLUTION: The cooling structure of a rotary electric machine for vehicle has a fan and a cooling duct. The fan is disposed in each casing of plural rotary electric machines and rotates together with a rotation axis of the rotary electric machine. The cooling duct connects between the casings of plural rotary electric machines. Inner air in the casing is circulated among the plural rotary electric machines by the rotation of the fan.SELECTED DRAWING: Figure 2 【課題】ケーシング内への異物等の進入を抑制した上で、ケーシング内を効率的に冷却できる車両用回転電機の冷却構造を提供することである。【解決手段】実施形態の車両用回転電機の冷却構造は、ファンと、冷却ダクトと、を持つ。ファンは、複数の回転電機のケーシング内に各別に配設され、回転電機の回転軸とともに回転する。冷却ダクトは、複数の回転電機のケーシング間を接続するとともに、ケーシング内の内気をファンの回転により複数の回転電機間で循環させる。【選択図】図２
