Even if a resistance force that causes the movable shaft to stick to the movable shaft bearing is generated by the water seal part that is provided between the movable shaft and the movable shaft bearing to prevent water leakage by shifting the timing, the total force applied to the movable shaft by the actuator is It can be used as the destructive force of the sticking resistance, and the valve is then opened. Therefore, the sticking destructive force of the movable shaft can be strengthened while decentralizing the drive of the valve opening operation of the actuator and designing a small and low capacity. Further, it has an effect of reducing the vibration and vibration noise of the valve body which are likely to occur when adjusting the small amount of water.
