PURPOSE:To contrive to make a transmission case small in size as well as to reduce parts in number by rotatably supporting a shaft cam stopper onto a change shaft, and thereby letting it be brought resiliently in contact with a cam stopper plate by a twisting spring engaged with the transmission case side. CONSTITUTION:A shaft cam 1 is rotated by a deriving gear 5 supported by a change shaft 16 which is rotatably supported onto the case side 14 of a transmission via a shaft lever 5a, and a cam stopper 17 composed of a roller 22 and of a lever 21 which is resiliently brought in contact with the stopper plate 7 of the cam 1 by a twisting spring 19, allows the cam 1 to be accurately displaced in pitch one by one by the rotation of the change shaft 16. By this constitution, the transmission case can thereby be made small in size with parts reduced in number. |
