Abstract
A blade portion that rotates integrally with a target shaft portion is provided between a target outer peripheral surface that is an outer peripheral surface of the target shaft portion and a tubular inner peripheral surface of a case. A first opening that communicates with a first oil passage is located away, on a first axial side, from a second opening that communicates with a second oil passage. The first oil passage communicates with an oil reservoir. The second oil passage communicates with a target space to which oil is supplied. Assuming that a forward rotation state is a rotation state of each part when a wheel is rotating in a direction in which a vehicle moves forward, the blade portion force-feeds the oil to a second axial side when the target shaft portion is in the forward rotation state.
