To achieve exhaust gas recirculation control corresponding to a load of an internal combustion engine with a simple structure, in an exhaust gas recirculation control device of the internal combustion engine controlling an amount of exhaust gas recirculated between an exhaust system and an intake system of the internal combustion engine.
A first diaphragm valve 31 opened according to action of a negative pressure of an intermediate passage 35, is disposed between an exhaust system-side passage 33 communicated with an exhaust passage of an exhaust system and the intermediate passage 35, and a second diaphragm valve 32 closed according to lowering of a negative pressure of an intake system-side passage 34 with respect to a valve opening pressure of the first diaphragm valve 31, is disposed between the intake system-side passage 34 communicated with an intake passage of an intake system and the intermediate passage 35.
