Abstract
A drive apparatus includes a motor, a transmission system, and a housing having a motor housing accommodating the motor and a gear housing accommodating the transmission system. The transmission system includes a first gear supported by a first bearing and a second gear supported by a second bearing. The gear housing includes first and second holding portions holding the first and second bearings. Surrounding ribs project from a wall surface of the gear housing, and surround an area that encompasses the first and second bearings when viewed in an axial direction. The surrounding ribs include arc-shaped ribs along outer circumferential edges of the first and second bearings, and straight ribs connected to the arc-shaped ribs. One or more of the straight ribs are each located on a common tangent to the first bearing and the second bearing.
