Abstract:
A rotary electric machine includes a rotor having a hollow shaft, a housing, a current shunter fixed to the housing and in electrical contact with the shaft and the housing, and a nozzle member for feeding a fluid inside the shaft. The shaft has an open end portion on a first axial side. The housing includes a bottom wall on the first axial side from the open end portion, and a peripheral wall protruding from the bottom wall toward a second axial side and surrounding the open end portion. The nozzle member has a feeding tubular part at least partly inserted inside the shaft from the open end portion, and a flange portion protruding radially outward from the feeding tubular part. The current shunter is located radially inside the peripheral wall, and the flange portion is located between the current shunter and the bottom wall in an axial direction.
