Claims

[Claim for Utility Model Registration] An operating pedal is provided on a bracket fixed to the vehicle body so as to be rotatable around a single axis and is mechanically connected to the parking brake, and the operating pedal is depressed from its original position. In the foot-operated parking brake operating device, the parking brake is brought into a braking state by being rotated by the operator, and the braking state of the parking brake is continuously maintained by maintaining the depressed state of the operation pedal. It is held by one member of the operating pedal and is always biased by a biasing means in a direction in which it comes into contact with the bracket and the other member of the operating pedal, and when the operating pedal is depressed and rotated. Friction that slides into contact with the other member to allow its rotation, but when the operation pedal attempts to rotate in the direction toward the original position, it frictionally engages with the other member and prevents the rotation. A foot-operated parking brake operating device characterized by being provided with an engaging member.
