An exhaust gas recirculation apparatus includes a housing connected with an EGR cooler via a mount face. The housing has a valve chamber accommodating a selector valve. The housing has a partition extending from the mount face close to the valve chamber to divide first and second exhaust ports opened in the mount face. A first passage leads exhaust gas into the EGR cooler through the valve chamber. A second passage recirculates exhaust gas to the intake passage through the EGR cooler and the valve chamber. A bypass passage leads exhaust gas from the engine through the valve chamber to bypass the EGR cooler. A rotation axis of the selector valve is perpendicular to an axis of the mount face, and offset away from the partition.
