Abstract
PURPOSE: To facilitate manufacture, relatively reduce weight, and highly efficient ly transmit a driving force in a plurality of transmission ratios by making only one claw capable of being engaged with the corresponding ratchet ring, and rotating a shaft to engage the other claw to the corresponding ring to change the propulsive ratio. CONSTITUTION: A second tubular member 30 is horizontally connected to a tubular lever 15 on the left side of a user, and a grip 31 is rotatably connected to the tubular member 30. A hollow lever 15 has a first shaft 39 in the inner part, and each of claws 40, 41, 42, 43 and 44 is mounted on the recessed of the shaft 39. Each claw is energized by a spring 45, and mounted on the shaft 39 so as to be turnable around a pin to some degree. The claws 40-44 are arranged around the shaft 39 so that only one claw is engaged with a corresponding ratchet ring 21-25. The selection of the claw is performed by turning the shaft 39. The turning position of the shaft 39 is visually confirmed by a dial.
