Claims (1)

[Scope of Claim for Utility Model Registration] (1) An operating pedal that is rotatably provided on a bracket fixed to a vehicle body and is rotatable about a single axis, and that operates a parking brake when pressed with a foot, and said single axis a rotating member having a cylindrical outer circumferential surface concentric with the operating pedal and rotating integrally with the operating pedal; a rotating member that is wound in contact with the cylindrical outer circumferential surface of the rotating member and has one end fixed to the bracket; When the operating pedal is pressed down from its original position, the winding is loosened to allow the rotating member to rotate, but when the operating pedal attempts to rotate in the opposite direction, a coil member that tightens the rotating member to prevent rotation of the rotating member; and a coil member that is movably disposed on the bracket and that is engaged with the other end of the coil member when a release operation is performed. a foot-operated parking brake operating device comprising a release member whose other end is moved in a direction to loosen the winding of the coil member, the release member being disposed on the bracket so as to be able to come into contact with and separate from the operating pedal; is biased in the direction of contact with the operating pedal, and when the operating pedal is depressed from its original position, it slides into contact with the operating pedal and allows its rotation, but when the operating pedal is pressed in the opposite direction. When the coil member attempts to rotate, it frictionally engages with the operation pedal to prevent the rotation, while the release operation causes the coil member to be separated from the operation pedal before the winding of the coil member is loosened. A foot-operated parking brake operating device characterized by being provided with a frictional engagement member. (2) One of the operating pedal and the bracket is provided with a wound member having a cylindrical outer peripheral surface concentric with the one axis, and one end of the wound member is fixed to the operating pedal. At the same time, the other end is fixed to the bracket, and when the operation pedal is held at the original position, it is brought into close contact with the cylindrical outer peripheral surface of the wound member, so that the operation pedal is moved in the opposite direction from the original position. A torsion coil spring is wound that restricts the operation pedal from rotating in the opposite direction, but expands in diameter when the operation pedal is depressed from the original position and applies a biasing force to rotate the operation pedal in the opposite direction. The foot-operated parking brake operating device according to claim (1), wherein the foot-operated parking brake is rotated.
