Claim 0:
1. A drive apparatus, comprising:
a motor that has a motor shaft extending in an axial direction;
a transmission mechanism that is connected on one side in the axial direction of the motor shaft;
a lock mechanism that restricts driving of the transmission mechanism;
a housing that houses the motor, the transmission mechanism, and the lock mechanism;
an oil that is stored in the housing; and
an oil passage that circulates the oil,
wherein
the housing includes:
a motor room that houses the motor,
a gear room that houses the transmission mechanism and the lock mechanism, and
a partition that is provided between the motor room and the gear room,

the oil passage includes:
a pump that pumps the oil in the oil passage,
a first feed flow passage that feeds the oil to the motor, and
a second feed flow passage that feeds the oil to the lock mechanism,

the first feed flow passage includes:
an intra-wall flow passage that extends along a wall surface in an interior of the partition, and
a motor feed flow passage that extends from the intra-wall flow passage on the other side in the axial direction, and feeds the oil to the motor, and

the second feed flow passage extends from the intra-wall flow passage to the one side in the axial direction so as to penetrate the partition, and opens to an interior of the gear room.
