ELECTRIC PARKING BRAKE DEVICE FOR VEHICLE

Provided is an electric parking brake device for a vehicle, including: a drum brake arranged on a radially inner side of a rim portion; and an electric actuator which enables obtaining a parking brake state by driving the drum brake, the electric actuator being mounted to a side surface of a back plate on an inner side in a vehicle-width direction. An ice and snow accumulation suppressing member (54) including a wall portion (54a), which extends from the back plate to the inner side in the vehicle-width direction while facing an inner peripheral surface of the rim portion (40b) and which is arranged at least below an anchor portion (21), is mounted to an outer peripheral edge portion of the back plate (13). On a projected figure on a plane orthogonal to a rotation axis (C) of a vehicle wheel, an outermost edge (54aa) of the wall portion along a radial direction of the back plate is arranged outside of an imaginary circle which passes through an outermost end of the electric actuator (44) in the radial direction and which is centered on the rotation axis. With this configuration, collision of ice and snow refrozen in a wheel with the electric actuator can be prevented.
