Document Type and Number:
WIPO Patent Application WO/2023/189032
Kind Code:
A1
Abstract:
One aspect of a drive device of the present invention is a parking device for locking rotation of one shaft of a power transmission part disposed inside a housing, the parking device comprising a parking mechanism disposed inside the housing, and an actuator which has a rotary part rotating around a drive axis and is disposed outside the housing. The parking mechanism comprises a parking gear mounted on an outer circumferential surface of the shaft, a parking pole, and a transmission part which has a rotation shaft connected to the actuator, and transmits a drive force of the actuator to the parking pole. The rotary part has a cylindrical-shaped cylinder part which has an inner circumferential surface with a plurality of spline grooves extending in an axial direction of the drive axis, and a first surface oriented to one side in the axial direction of the drive axis. The rotation shaft has a first end part, which has an outer circumferential surface with a plurality of spline protrusions extending in the axial direction of the drive axis and is inserted into the cylinder part, and a second surface opposing the first surface.
