Abstract
A split face of an exhaust passage-defining member is coupled to a split face provided at a rear portion of an oil case interposed between an engine block and an extension case. A main exhaust gas expansion chamber and a subsidiary exhaust gas expansion chamber are defined between the exhaust passage-defining member and the oil case, so that an exhaust gas supplied from a first exhaust passage in the oil case is discharged into a second exhaust passage in the oil case via the main exhaust gas expansion chamber. A portion of the exhaust gas in the main exhaust gas expansion chamber is passed through a communication bore and the subsidiary exhaust gas expansion chamber and discharged from an exhaust outlet into the air.
