Claims

[Claims for Utility Model Registration] A parking brake pedal that is rotatable around a first rotation center line and has a pedal pad on its free end that is to be stepped on by a foot; a lever that is rotatably provided around a second rotational centerline that is parallel to the first rotational centerline and located away from the first rotational centerline, and that is connected to the parking brake via a brake wire; and the parking brake pedal. and an engagement tooth formed along an arc centered on the rotation center line of one of the levers, and a third engagement tooth that is close to the engagement tooth and parallel to the first rotation center line. The parking brake pedal is provided so as to be rotatable around a three-turn center line, and is engaged with the engagement teeth to prevent the parking brake pedal from returning from the depressed position to the original position, thereby maintaining the parking brake in an applied state. a release operating device that releases the engagement of the pawl with the engagement teeth and allows the parking brake pedal to return from the depressed position to the original position; and either the parking brake pedal or the lever. a roller engaging portion provided on the other hand, and a roller engaging portion provided rotatably around an axis parallel to the first rotation center line on the other hand and rolling on the roller engaging portion as the parking brake pedal rotates. and a roller that transmits the rotation of the parking brake pedal to the lever, and the relative positions of the first rotation center line, the second rotation center line, and the axis of the roller are such that the parking brake pedal A lever ratio increasing foot parking brake operating device, characterized in that the lever ratio as a whole is selected to increase as the lever ratio rotates from the original position to the depressed position.
