Abstract
An exhaust gas recirculation device in accordance with the present invention has an exhaust gas recirculation valve interposed between the exhaust system and the intake system of an internal combustion engine, an exhaust gas recirculation cooler for cooling exhaust gas sent from the exhaust gas recirculation valve to the intake system, and a bypass valve that bypasses the exhaust gas recirculation cooler and sends the exhaust gas to the intake system. The exhaust gas recirculation cooler is put adjacently between the exhaust gas recirculation valve and the bypass valve.
