Abstract
A rotating electrical machine configured with a rotor and stator. The rotor is rotatably supported radially inside of a stator that has coil end portions on both sides in an axial direction, and which is structured so that oil is supplied from an axial first direction side to the coil end portions on the both sides in the axial direction. A communication oil passage provided in at least one of the rotor and the rotor support member, is configured to communicate with a first opening and a second opening from an oil collecting portion. The first opening opens radially inside the coil end portion on the axial first direction side, and the second opening opens radially inside the coil end portion on an axial second direction side, which is the other side in the axial direction of the rotor.
