Abstract
A partition wall partitioning a cooler inlet port and a cooler outlet port extends from a cooler connecting surface of a connecting portion to a vicinity of a shaft supporting a four-way butterfly valve. An EGR gas leakage around a first valve plate can be restricted. Thus, an increase in temperature of EGR gas flowing through an EGR gas outlet port can be restricted at a cooled mode. A deterioration of emission reducing performance can be avoided.
