  • Publication number: 20150151635
    Abstract: A vehicle is provided with a clutch pedal which, when depressed, interrupts the transmission of drive power from the engine to the drive wheels. The clutch pedal is constituted by a pedal section and an arm having the pedal section attached to the lower part thereof. The arm can swing about the upper part thereof and is connected to a clutch disk within a transmission through a link mechanism. An elastic member is provided between the arm and a machine body. The vehicle is configured in such a manner that when the clutch pedal is depressed, the elastic member acts in a pressing-back direction until the clutch pedal reaches a first predetermined position, the pressing-back direction being the direction in which the elastic member presses back the arm; when the clutch pedal is depressed beyond the first predetermined position, the elastic member acts in the direction in which the arm is pressed in; and when the clutch pedal is depressed up to a second predetermined position, the clutch disk is separated.
