Then, the rack gear 28 connected to the actuating rod 4 moves linearly, and accordingly, the screw 30 moves linearly to pull the push rod 10 so that the adjustment lever 8 is activated to operate the parking brake 6. Operate and lock the propeller shaft 34.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 차량용 파킹 브레이크 조작기구는 파킹레버를 당기면 작동로드가 당겨지고 변환기구에 의해 작동로드의 직선 이동이 직각방향으로 직선이동으로 변환되어 푸시로드가 직선 이동되면서 파킹 브레이크를 조작하기 때문에 , 조작 응답성을 향상시킬 수 있고, 파킹 브레이크의 해제가 보다 완벽하게 이루어지므로 엔진의 손상을 방지할 수 있는 이점이 있다.Therefore, the vehicle parking brake operating mechanism according to the present invention constructed and operated as described above is pulled by the parking lever, and the driving rod is pulled, and the linear movement of the operating rod is converted into a linear movement in a perpendicular direction by the converter mechanism, so that the push rod is straight. Since the parking brake is operated while being moved, the operation responsiveness can be improved, and the parking brake can be released more completely, thereby preventing damage to the engine.
