Abstract
A pair of throttle valves are installed to first and second installation holes of a cylinder tube, respectively. The throttle valve comprises a rotatable member, a needle which is engaged with the rotatable member and which controls the flow rate of a pressure fluid flowing through first and second bypass passages formed in each of the first and second installation holes, a covering member which covers each of said first and second installation holes, and a stopper ring which prevents the displacement of the rotatable member.
