ABSTRACT:
In an electric parking brake device, an equalizer is pivotably carried at its center part on a nut which is caused by an electric motor to perform linear reciprocating motion, and parking brakes are operated by respective cables which are connected respectively to the opposite end portions of the equalizer. Stop members are provided for preventing the pivot movement of the equalizer in the state that the equalizer is held returned by the operation of the electric motor to an extreme position on the side of the parking brakes. The stop members may be composed of a first stop member for preventing the equalizer from being pivoted in one direction and a second stop member for preventing the equalizer from being pivoted in the other direction, or may be constituted by a member of one piece structure for preventing the equalizer from being pivoted in both directions.
