動装置。 A reversing switch type fuel pump switch that connects when the oil pressure increases, and a variable body for the oil pressure meter that changes the resistance value by moving the movable body with a sliding electrode whose free end slides into contact with the resistor according to the oil pressure. In a hydraulically actuated device in which a resistance device and a pressure cancel device consisting of a bellows for releasing the increased internal pressure due to movement of a movable body to the outside are integrated into the same case, the open end of the bellows is removed. A hydraulic actuation device that is folded back toward the side and has a hard ring fitted inside.
