Abstract
PURPOSE: To provide high driving force by making a pedal body wide in width in the longitudinal direction, connecting a pedal shaft to the tip shaft of a crank via a one-way clutch means having a ratchet and an engaging pawl, integrating them at the time of treading, and treating the tip section of the pedal. CONSTITUTION: Wide plates E, F are provided at the front and rear of a pedal shaft 3 to make a pedal body wide in width in the longitudinal direction. The neck section 6 of the pedal shaft 3 is connected to the tip shaft of a crank 2 via a one-way clutch means B constituted of a ratchet wheel and a ratchet excited by a spring. When the pedal body is treaded forward and downward than a chain wheel, the pedal body and the crank 2 are integrally coupled by the one-way clutch means B, and the front tip section of the pedal body can be treated. The length from a crank shaft to the pedal tread position is increased, and high driving force can be obtained with constant treading force.
