Claims

[Scope of utility model registration request]

In a vehicle gear shift operation device that is equipped with a main transmission that can be switched to multiple gears and a sub-transmission that can be switched between a high speed position and a low speed position at each gear position of the main transmission, A clutch operating device main body is provided, which includes a power cylinder into which fluid pressure corresponding to the pedaling force is introduced, and which operates the clutch to shut off in accordance with the introduced fluid pressure, and which also responds to the fluid pressure introduced into the clutch operating device main body. The relay includes a piston and a relay valve that is opened and closed by the piston, and the relay controls the disconnection state between the fluid supply source and the fluid pressure operation circuit that switches the sub-transmission between a high speed position and a low speed position. 1. A vehicle gear shift operating device, comprising: a sub-transmission control mechanism controlled by a valve.
