The partition is arranged to partition an inside of the first exhaust passage into an upstream side and a downstream side. The communication portion is arranged to make the upstream side communicate with the downstream side of the partition in the first exhaust passage. The exhaust gas concentration sensor is arranged on the upstream side of the partition in the first exhaust passage. The catalyst is arranged on an upstream side of the exhaust gas concentration sensor in the first exhaust passage.
