摘要： A connecting passage is formed inside a cylinder head, which extends rearward from an exhaust passage and connects to the exhaust passage. The connecting passage branches inside the cylinder head into two branch passages, which open at a rear end face of the cylinder head, respectively. An opening portion, one of opening portions of the branch passages, connects to an EGR cooler, and another opening portion, the other of opening portions of the branch passages, connects to a bypass pipe. Accordingly, the exhaust gas recirculation device of an engine which can restrain the device from being improperly large sized, providing the EGR cooler and the bypass pipe, can be provided.
