    摘要： 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.

    摘要翻译： 在电动驻车制动装置中，运动传递构件和介入构件之间的接触部分处的运动传递力的力线位于螺杆轴构件和螺母构件之间的接合部分的外表面的内侧。 因此，当螺杆轴构件的直线运动导致停车杆枢转运动时，在接合部处不发生浮动，从而可以在接合部处防止单侧撞击。 因此，停车杆可以平稳地转动。 此外，与干涉构件接触的运动传递构件的一个表面采取弯曲表面以抑制驻车杆枢转运动的运动中的滑动。 因此，能够防止运动传递部件的运动传递力成为偏移负荷，实现驻车杆的平稳的枢转运动。

    摘要： 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.
