  • Patent number: 9051983
    Abstract: In the interior of a brake drum, the arrangement space in the rotational axis direction of the brake drum is spacious in comparison with that in the direction orthogonal to the rotational axis direction in which an anchor portion, hub components on the vehicle body side and the like are arranged. An electric parking brake device is provided with the anchor portion that supports respective one ends of brake shoes. A parking lever is pivotally moved by a drive unit operated by an electric motor for pushing the brake shoes toward the brake drum. The anchor portion and the drive unit are arranged to be piled up in the rotational axis direction of the brake drum which is spacious in comparison with the direction orthogonal to the rotational axis direction.

  • Publication number: 20120193178
    Abstract: In an electric parking brake device, the force line of a motion transmitting force at a contact portion between a motion transmitting member and an intervention member is located inside of an outer surface of an engaging portion between a screw shaft member and a nut member. Thus, when a linear motion of the screw shaft member causes the parking lever to pivotally move, no floating takes place at the engaging portion, so that a one-side hitting can be prevented at the engaging portion. Therefore, the parking lever can be pivotally moved smoothly. Further, one surface of the motion transmitting member contacting the intervention member takes a curved surface to suppress a slippage in the movement that the parking lever is pivotally moved. Therefore, the motion transmitting force by the motion transmitting member can be prevented from becoming an offset load, realizing a smooth pivot movement of the parking lever.
