Claims

[Scope of utility model registration request]

a first diaphragm whose periphery is fixed to the case and whose central part is connected to one end of a substantially orthogonal rod to form a first negative pressure chamber between it and the case; and whose periphery is fixed to the case and whose center part is connected to the rod. a second diaphragm having a hole passing through the hole, the periphery of the hole being fixed to the inner wall of the case, spaced apart from and substantially parallel to the first diaphragm, and forming a second negative pressure chamber between the second diaphragm and the case; 2. An annular stopper that moves integrally with the diaphragm and has a hole through which the rod passes, the case is fixed to a housing of the distributor, and the other end of the rod is connected to a breaker plate;
An ignition timing control device for an internal combustion engine, comprising a first spring and a second spring arranged to guide engine suction negative pressure to the first negative pressure chamber and the second negative pressure chamber, respectively, and to oppose the suction negative pressure.
