。[Claims for Utility Model Registration] 1. A fuel chamber and an air chamber are defined by a casing and a diaphragm, the fuel chamber has an inlet passage and an outlet passage, and the outlet is controlled by a movable valve body that operates integrally with the diaphragm. A diaphragm pressure control valve for opening and closing a passage, characterized in that the diaphragm pressure control valve is provided with means for restricting the diaphragm from moving beyond a permissible stroke. 2. In the statement in paragraph 1 of the axis circumference of the utility model registration request, the holding member on the center side of the diaphragm has a convex portion on the air side, and the bottom surface of the casing member on the air chamber side is arranged opposite to the tip of the convex portion, and is held. A diaphragm pressure control valve characterized in that the distance between the tip of the convex part of the body and the bottom of the casing member is smaller than the allowable stroke of the diaphragm. 3. The diaphragm pressure control valve according to claim 2, characterized in that the convex portion of the holding body is a separate member. 4 Utility Model Registration The diaphragm pressure control valve according to claim 2, characterized in that the convex portion of the holding body is provided on the bottom surface of the casing member on the air chamber side.
