Abstract
A rotating electric machine includes a case, a stator, a first rotary member including a rotor core and a first shaft, a second rotary member including a second shaft, and a multiple disc clutch. A first oil passage and a second oil passage are provided inside the case. The first oil passage starts from an inside of the first shaft or an inside of the second shaft, passes through the multiple disc clutch from an inner side to an outer side in a radial direction with respect to a rotation center, and reaches an inner side of the rotor core in the radial direction. The second oil passage starts from the inside of the first shaft or the inside of the second shaft and reaches the inner side of the rotor core in the radial direction without passing through the multiple disc clutch.
