Claims

[Scope of utility model registration request]

The arm part engages with a pole that elastically meshes with the sector teeth provided on the pedal of the foot-operated parking brake to fix the pedal in a rotational position. a movably supported release lever;
A release cable is provided with one end connected to the rotation end of the release lever, and the release lever is rotated by pulling the release knob provided at the other end of the release cable and pulling the release female cable. In the brake release mechanism of the foot-operated parking brake, the brake release mechanism of the foot-operated parking brake is configured such that the pawl is pushed by the arm portion, the meshing between the pawl and the sector teeth of the pedal is released, and the pedal is returned to its original position. The base rotatably supports a lock lever that has an arm that can be engaged with and detached from the release lever, and also has a plunger that can move forward and backward, and when the pedal is in the rotation position, the plunger is energized by a switch operation. A retracting solenoid is installed, the plunger is connected to the lock lever, and its arm is positioned within the rotation locus of the release lever in the release direction to restrict rotation in the release direction, and the solenoid The foot-operated parking lot is characterized in that the lock lever is swung by energization, and its arm is retracted out of the rotation locus of the release lever to allow rotation in the release direction. Brake release mechanism.
