Abstract: A motor shaft of a drive apparatus extends along a first rotation axis extending in an axial direction. A gear portion is connected to one axial side of the motor shaft. A housing tubular portion extends in the axial direction and holds a stator on the radially inner surface. The first lid portion is attached to the other axial end portion of the housing tubular portion. The first bearing of the motor bearing that rotatably supports the motor shaft is a rolling bearing disposed on the first lid portion, and rotatably supports the motor shaft on the other axial side with respect to the rotor. The motor shaft and the first lid portion are electrically insulated by the first bearing.
