PROBLEM TO BE SOLVED: To decrease the temperature of the circumference of an engine and facilitate the control of a tail hose. SOLUTION: A silencer 32 provided on an exhaust pipe 28 is constituted to be provided on the contrary side of the engine 7 by sandwiching a radiator 10. Thereby the temperature of the circumference of the engine 7 can be prevented from increasing. In addition, since the silencer 32 is provided as a vertically putting state in which an axial line is a vertical line, the installed area of the silencer 32 is lessened to secure a space on the circumference of the silencer 32, and can cope with the design modification of the tail hose 34. Furthermore, since the silencer 32 is arranged in the lowermost downstream side of cooling wind by a cooling fan 8, the cooled wind before temperature increase by the heat of the silencer 32 can be supplied to the radiator 10 and an oil cooler 12.
