Abstract
An actuation chamber () provided in a housing () is communicatively connected to a supply and discharge port () via a pressurized oil supply and discharge passage (). A valve case () of a sequence valve () is attached to an attachment hole () provided at an intermediate portion of the supply and discharge passage (). A valve seat () is provided in a cylindrical hole () provided in the valve case (). A valve member () is biased leftward toward the valve seat () by a pressure-setting spring (). When pressure of pressurized oil supplied to a first portion of the supply and discharge passage () which is close to the supply and discharge port () exceeds a set pressure, the pressurized oil moves the valve member () rightward for valve opening, against the pressure-setting spring ().
