Abstract: An engine unit includes an engine, an exhaust gas treatment device and a connecting pipe. The engine has an exhaust gas port. The exhaust gas treatment device is arranged above the engine. The connecting pipe connects the exhaust gas port and the exhaust gas treatment device. The connecting pipe has an expandable-contractible bellows portion. The bellows portion has a linear form following the upward-downward direction. The lower end portion of the bellows portion is positioned lower than at least a part of the exhaust gas port.

Abstract: An exhaust gas treatment unit includes an exhaust gas treatment device, a bracket and a connecting pipe. The exhaust gas treatment device is mounted on a bracket. The connecting pipe is connected to the exhaust gas treatment device. The connecting pipe directs exhaust gas to the exhaust gas treatment device. The connecting pipe may include a supporting portion and a pipe portion, with the supporting portion supporting the bracket and the pipe portion being integrated with the supporting portion. Alternatively, the exhaust gas treatment unit may further include a supporting member having a supporting portion supporting the bracket and a pipe portion integrated with the supporting portion, with the pipe portion connected to the connecting pipe.
