Claims

[Claims for Utility Model Registration] 1. A body in which a cylinder chamber is formed, a hollow piston rod having a piston and slidably inserted into the body, and a piston rod that is slidable in the hollow portion of the piston rod. The piston rod includes an operating rod that is fitted into the piston rod, an operating force output portion that is connected to the piston rod so as to move together, and a joint member that is attached to the operating rod so as to connect the change lever. , transmitting the operating force of the change lever to the operating rod to cause the operating rod to slide within the piston rod, and this movement causes fluid pressure to act on the piston of the piston rod to follow the movement of the operating rod. let me,
In the transmission operation booster configured to obtain the transmission operating force boosted by the piston rod from the operating force extraction part, the operating force extraction part is connected to the shaft of the piston rod at one end thereof. It is located above the heart, and on the other hand,
A booster for operating a transmission, characterized in that the joint member is disposed on an axial extension of the operating rod so as to avoid the operating force extraction portion. 2. A bypass rod is provided at the end of the operating rod on the side of the operating force take-out part so as to bypass the take-out part, and the coupling means is disposed at the tip of the bypass rod. A booster for operating a transmission according to claim 1 of the utility model registration claim.
