Abstract
A shift lever assembly for use in a bicycle wherein a wire connected at its one end to a derailleur is wound up or paid out to operate the derailleur. The assembly comprises a lever pivot fixed to the handlebar of the bicycle; a shift lever having a base-end boss portion rotatably supported by one end of the pivot and an arm portion extending from the boss portion; wire winder separate from the lever and rotatably supported by the pivot; a lever-coupled member provided between the boss portion and the winder and supported by the pivot so as to be rotatable with the winder; and a clutch for transmitting the rotation of the shift lever to the lever-coupled member. The shift lever is so biased by a spring as to return to a neutral position for starting rotation toward the wire winding direction and the wire paying-out direction. The clutch transmits to the lever-coupled member the rotation of the lever from the neutral position through a desired angle but does not transmit to the lever-coupled member the rotation of the lever to the neutral position.
