PURPOSE:To prevent fuel discharged from an air exit from flowing along the outer face of an exhaust pipe by providing a fuel collecting part for collecting unburnt fuel discharged from the air release pipe as well as lead-out pipes for leading the fuel in the collecting part out into a specified discharge position. CONSTITUTION:When unburnt fuel adhered to the inner wall of a tail pipe is pushed out toward an air exit with exhaust air, a part of the fuel discharged from the air exist flows down through the outer face of the tail pipe and flows into a clearance between the tail pipe and a cover pipe 68. As a discharge hole is formed at the front end lower face of each cover pipe 68, the fuel is collected at a collecting part 76 through the air exit. The fuel collected at the collecting part 76 is then led into the lower end part of a left side rear frame 40 through a first and a second lead-out pipes 78, 80 and discharged outside through the discharge port. |
