A drive apparatus includes 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. 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.
