Abstract: The electric brake motor unit has: a motor; a connector having a connector terminal; a first section extending in a first direction and having a first contact portion electrically connected to the connector terminal; a second section extending in the first direction and having a second contact portion electrically connected to a motor terminal; and an intermediate section extending in a second direction intersecting with the first direction between the first section and the second section. The electric brake motor unit is provided with: a bus bar in which the first section, the intermediate section, and the second section are connected in a crank shape; and a motor bracket mounted on the motor and having two positioning portions that are mutually separately positioned with a space through which the intermediate section passes and are used for positioning the intermediate section in the first direction.

Abstract: A parking brake actuator generates and applies a braking force to a vehicle wheel in such a manner that the parking brake actuator converts a rotational motion of a screw member, which is rotated by an electric parking brake driving device, into a translatory motion and transmitting the converted translatory motion to a piston to push a brake pad toward a disc by the piston. The electric parking brake driving device includes an electric motor and a reduction gear mechanism which transmits driving force of the electric motor to the parking brake actuator. The reduction gear mechanism includes a gear body and a planetary gear mechanism, which is provided within the gear body and into which the driving force of the electric motor is inputted. A cushion rubber, which is compressible in the circumferential direction, is interposed between a ring gear of the planetary gear mechanism and the gear body.
