Abstract
A pedal parking brake device makes it possible to provide a brake retaining state at the maximum braking position. The pedal parking brake device performs a rotational locking of a brake pedal by a coil spring provided at a rotatably supporting position of the brake pedal and includes a supporting shaft fixedly provided at a base plate, a cylindrical core bar loosely and rotatably inserted into the supporting shaft, a brake pedal rotatably attached to a center of the supporting shaft, a brake plate in which a brake hole is provided, integrally formed with the core bar, and a release plate for the coil spring. An outer coil spring is outwardly inserted to the core bar and an inner coil spring is provided at the inner side of the core bar so that its outer diameter may be separately connected with the inner periphery of the core bar. An operation of the parking brake and brake locking are performed by continuously connecting both coil springs to the brake pedal.
