PURPOSE: A parking brake of a vehicle is provided to prevent the degradation of the brake power even when a vehicle is parked on a stiff ramp road by restraining the rotation of a propeller shaft. CONSTITUTION: A propeller shaft gear(11) for transmitting the driving force of an engine(6) to rear wheels(9) via a differential(8) is installed at a portion of a propeller shaft(7). An actuator(12) is placed parallel to the propeller shaft. A brake gear(14) is fixed on the end of the actuator rod. The brake gear is engaged with the propeller shaft gear by the parallel movement of the actuator rod with the propeller shaft. Therefore, the propeller shaft is restrained from rotating, and the brake power is maintained even on a stiff ramp road.
