摘要： During normal operation in which an electric braking device is operative, when a depressing force cut-off valve is closed and communication between a master cylinder and a disk brake system of a front wheel is cut off, the front wheel is braked by a brake pad directly driven by drive force of the electric braking device. When there is an abnormality in which the electric braking device breaks down, a wheel cylinder of a drum brake system of a rear wheel is operated by brake fluid pressure generated by the master cylinder operated by a driver's braking operation. Thus, since the drum brake system having a high braking function is operated in case of abnormality, the braking force is higher than the braking force during normal operation, thereby reliably stopping the vehicle.

摘要： An electrically driven parking brake device includes a ratchet mechanism for restricting movement in a brake releasing direction of a piston which is operated by an electrically driven motor to generate a braking force. In the ratchet mechanism, a ratchet wheel is temporarily rotated in a braking direction to disengage a ratchet pole from the ratchet wheel, thereby releasing the braking force. Even when the electrically driven motor fails to be unable to release the braking force, a manually operated bolt presses the ratchet pole to disengage the ratchet pole from the ratchet wheel, thereby releasing the braking force. Thus, the situation where the vehicle cannot move can be avoided, even when the electrically driven parking brake device is held in operation due to motor failure or the like.
