Claims

[Claims for Utility Model Registration] A reservoir tank for a hydraulic actuator of a clutch actuating device, comprising a first piston that is fitted and slidable within the reservoir tank body, a part of the first piston, and the above. an elastic body disposed between the stationary part of the tank body and having a bias to pressurize the first piston; and an elastic body disposed between the first piston and the stationary part of the tank body; a second piston having a fixed other end; and a first piston formed between a connection portion of the tank body with the hydraulic actuator and a position opposite to a lower end of the first piston. a pressure chamber; a second pressurization chamber formed at a position facing the lower end of the second piston in the first piston and communicating with the first pressurization chamber; and the first piston. a check valve provided at the lower end and biased in a direction to cut off communication with the second pressurizing chamber; and one end of the second piston at a position facing the second pressurizing chamber. and a hydraulic oil supply hole having a side opening and an opening on the other end communicating with the oil storage chamber inside the tank body, and the second hydraulic oil supply hole is provided with a hydraulic oil supply hole having a side opening and an opening on the other end communicating with the oil storage chamber inside the tank body, A clutch actuating device having a reservoir tank structure, characterized in that the pressure within the pressure chamber is made constant by the flow of oil through the hydraulic oil supply hole.
