置の制御弁。A rod, which is fixed at one end to a diaphragm that separates a negative pressure chamber connected to a negative pressure source and an atmospheric chamber open to the atmosphere within the casing, and which has a valve body at the other end, connects the intake passage and the exhaust passage. The exhaust gas is slidably penetrated through the pipe wall of the connected exhaust gas recirculation pipe via a sealing member, and as the rod is displaced, the valve body is seated on and separated from the valve seat, and the exhaust gas is recirculated from the exhaust passage to the hot air passage. In a control valve for an exhaust gas recirculation device that controls gas, an enclosure having a predetermined gap between the diaphragm and the sealing member of the rod is provided, and the enclosure has a predetermined gap between the diaphragm and the sealing member. A control valve for an exhaust gas recirculation device, characterized in that a sliding contact portion of a rod with the sealing member and the sealing member are covered from the diaphragm side.
