ABSTRACT:
A parking brake foot pedal is pivoted to a bracket, and is formed with a ratchet plate portion. A pawl is engaged with the ratchet so as to hold the parking brake in the applied condition. A release lever is pivoted to the bracket so that it displaces the pawl away from the ratchet when it is pulled by a release structure. A resin bush is attached to the release lever at a position remote from its pivoting point. The bush has a hole through it which is narrowest at its middle portion and opens out towards its ends. A release cable passes through this hole in the bush, and on its end there is fixed a stop member larger than the internal diameter of the hole in the bush. Thereby, the end of the release cable is flexibly coupled to the release lever, so as not to be subject to severe bending stress when the release cable is pulled and rotates the release lever so as to displace the pawl away from the ratchet and release the application of the parking brake.
