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.
