ク機構。 Near the tip of the crank arm fitted on the crankshaft, an extension arm to which a pedal is rotatably attached is connected so as to be able to advance toward the opposite side of the crankshaft and elastically retract toward the crankshaft side. A cam plate is provided on the pedal in order to extend the rotation radius of the pedal in the pedal pressing range during one rotation of the pedal and shorten it in the pedal release range, and the contact member is rotatable with the pedal and is provided on the crank arm. A crank mechanism for an automobile, characterized in that the crank mechanism is attached so as to be able to come into contact with and separate from the crank mechanism.
