Zusammenfassung:One aspect of a drive apparatus of the present invention includes a motor having a rotor that rotates about a motor axis and a stator that surrounds the rotor, a housing having a motor accommodating portion that accommodates the motor, a fluid stored in the housing, a flow path through which the fluid flows, and a pump that pressure-feeds the fluid in the flow path. The flow path includes a pipe-shaped intra-housing flow path that is disposed inside the motor accommodating portion and is provided with a feed hole for feeding the fluid to the motor, a pipe portion that is disposed inside the motor accommodating portion and relays between the pump and the intra-housing flow path, and an intra-side wall flow path that is provided in a wall portion of the housing and connects the pipe portion and the intra-housing flow path. The pipe portion and the intra-housing flow path are connected to each other by a coupling portion.
