Claims

[Claims for Utility Model Registration] A pedal bracket attached to the vehicle body, having a footboard at its free end, the base of which is rotatably supported by the pedal bracket, and transmitting engine power via pedal force transmission means. A clutch pedal that operates a clutch as a transmission means; a cam provided at the base of the clutch pedal; and a cam rotatably supported by the pedal bracket, and a portion between the cam and the cam that is rotatably supported by the pedal bracket. A hook is passed between a cam contactor on which a contact portion is formed, and the clutch pedal and the cam contactor, and a biasing force is applied to bias the contact portion of the cam contactor in a direction to bring it into contact with the cam. a spring, the cam has a cam surface that corresponds to the rotation of the clutch pedal from a free position to a maximum depression position, and rotates together with the clutch pedal; The cam surface is in sliding contact with a cam surface, and a portion of the cam surface corresponds to a period from the middle of depression of the clutch pedal corresponding to the beginning of disengagement of the clutch to the maximum depression position of the clutch pedal.
A clutch characterized in that the contact portion of the cam contactor is relatively separated from the clutch pedal to increase the biasing force of the biasing spring, resulting in a biasing force increasing surface that increases the pedaling force. Pedal force drop prevention device.
