Abstract

PURPOSE:To perform smooth shift operation, and to make shift positioning simple and possible to adjust easily by engaging a pair of shifter cylinders slidably along the axial direction of a shifter stay, and connecting these respective shifter cylinders to each other with a connecting member. CONSTITUTION:Shift arms 3, 4 operating speed change gears 1, 2 are provided. A pair of axial shifter cylinders 7, 8 holding clip balls 5, 6 are engaged slidably along the axial direction of a shifter stay 12 on which arranged clip grooves 9-11 to which engaged clip balls 5, 6. These respective shifter cylinders 7, 8 are connected to each other with a connecting member 13. In such way, moving resistance against the shifter stay 12 can be made small, so smooth shift operation can be performed.
