Patent ID: 8020486

Claim:
An operating device comprising: a pressurizing operation unit for applying a pressure to a pressure communicating medium in a fluid form; a plurality of action units for operating the pressure applied by the pressurizing operation unit by converting the pressure into a switching operation comprising a position fixed state and a released state of a positioning unit; a conducting channel for releasing the pressure communicating medium from the pressurizing operation unit; a bifurcating section for distributing the pressure communicating medium from the conducting channel to the plurality of action units; a branch channel for guiding the pressure communicating medium to each action unit from the bifurcating section; wherein each branch channel has a flow rate regulating unit for regulating a flow rate of the pressure communicating medium; and each of the flow rate regulating units equalizes the flow rate of the pressure communicating medium located in each of the branch channels; where the positioning unit comprises a cylinder and a piston located in the cylinder; where the positioning unit positions an extension device and includes a valve for opening and closing the flow of the fluid located in a cylinder chamber formed on both sides of the piston.
