CLUTCH PEDAL RETREAT SUPPRESSION MECHANISM The clutch pedal retreat suppression mechanism that restraints the retraction of the clutch pedal during a frontal collision has been adopted in order to reduce the shock to the driver's feet. In case of a frontal collision, when the pedal installation surface (dash panel) is retracted, the arm stopper set on the deck-cloth contacts the rear end of the clutch pedal arm to restraint the retraction of the pedal surface.
