PROBLEM TO BE SOLVED: To provide a ventilation cooled rotary electric machine for a vehicle which can be installed in a narrow installation space in a truck and by which satisfactory strength and ventilation cooling performance in a machine can be secured, the outside diameter of a stator iron core can be increased, and large output can be realized. SOLUTION: The ventilation cooled rotary electric machine for a vehicle, related to one embodiment, is constituted as follows. Cooling air is taken in from a cooling air inlet port 21 to one end side in the axial direction in the machine; the cooling air is ventilated to the other end side in the machine and exhausted to the outside of the machine by an air exhaust outlet; while part of the cooling air taken into the machine from the cooling air inlet port 21 is ventilated to ventilation paths 43a-43d for cooling the outer periphery of the iron core. The ventilation paths 43a-43d for cooling the outer periphery of the iron core are formed in the vicinity of a location where a line passing the rotating shaft and at approximately 45 degrees with respect to the vertical axis and the horizontal axis, and the outer peripheral face of the stator iron core 2 cross with each other, when viewed from the axial direction.
