Then, at least one of the valve member and the valve member chamber associates a value of spring load of a coil spring present in a peripheral direction of the spring with a value of a valve opening force that the inflow fluid flowed into the fluid inflow chamber through an inflow opening acts against the valve opening side at the valve member around an axis of a movable shaft, by defining a fixed position of the spring end part of the coil spring around an axis of the movable shaft of the valve member.SELECTED DRAWING: Figure 6
