御弁。[Claims for Utility Model Registration] (1) A negative pressure operating part such as a diaphragm operated by engine suction negative pressure, and a valve body connected to the negative pressure operating part via a valve stem to form a part of the engine exhaust gas. a control valve body that can selectively recirculate the valve body to the suction side of the engine; and an opening detection section that includes a variable resistor that has a slider connected to the valve stem to detect the range of the valve body. The exhaust gas recirculation control valve is characterized in that the head of the opening degree detection section is elastically held by a holding member toward the negative pressure operating section or the control valve body. control valve. (2) The holding member has one end hinged to a holder that comes into contact with the head of the opening detection section, and a locking section that is detachably attached to the control valve main body or the negative pressure actuation section. The exhaust gas recirculation control valve according to claim 1, characterized in that the exhaust gas recirculation control valve has an end. (3) Exhaust gas recirculation according to claim 1 or 2, wherein an elastic member is interposed between the head of the opening detection section and the holder. control valve.
