PURPOSE:To receive a large capacity fuel tank and enable its elastic support by disposing a separate fuel tank in a space part in the back of an engine unit in a cowling, elastically supporting its lower part by a damper member, and closely interposing a seal rubber between its upper surface and the lower surface of a ceiling plate. CONSTITUTION:At least one of the side and back of the rear protruding part of an engine 20a and a separate fuel tank 30 covering the upper part of the rear protruding part are disposed in a space part formed in the back of an engine unit 20 in a cowling, and the lower part of the fuel tank 30 is elastically supported to the engine unit by a rubber damper member 33. An oil feed port part 31 having a cap 35 disposed on its end provided on the upper surface of the fuel tank is protruded to the outside through an opening 11a provided on the ceiling plate of the cowling, and a seal rubber 36 is closely interposed between the lower surface of the ceiling plate around the opening 11a and the upper surface of the fuel tank 30. |
