装置のダイアフラム装置。A diaphragm connected to a rotary base plate having an engine ignition timing control unit via a connecting body, a case forming a pressure chamber together with the diaphragm and to which negative pressure of the engine is transmitted, and a case facing the diaphragm of the case. a stopper fixed in the case in a state protruding toward the diaphragm from a wall surface facing the diaphragm; a movable support plate engaged with the stopper so as to slide only in the direction of displacement of the diaphragm; and the movable support plate. and a first spring disposed between the movable support plate and the diaphragm and biasing the movable support plate in a direction away from the diaphragm; and a first spring disposed between the movable support plate and the wall surface of the case, In the diaphragm device for an engine ignition timing control device, the first and second springs and the movable support plate have substantially the same diameter. and the first spring is formed with an engine d
The elastic force in a state where the diaphragm is displaced and fully compressed by negative pressure is set to be equal to or smaller than the elastic force opposing the initial pressing force received by the second spring at the time of negative pressure. A diaphragm device for an engine ignition timing control device.
