<P>PROBLEM TO BE SOLVED: To configure an exhaust pipe compactly; to efficiently suck outside air by an ejector effect; and to easily discharge hot exhaust smoothly. <P>SOLUTION: The downstream end of an outside protecting tube is located downstream in the exhaust direction of the downstream end of an exhaust conduit so that an ejector portion 25 for sucking and introducing outside air between the outer periphery of the exhaust conduit and the inner periphery of the outside protecting tube by an ejector effect by exhaust discharged from the exhaust conduit is constituted at the downstream end of the exhaust pipe. Curved pipe portions 32b, 42b curved so as to change the exhaust direction are provided to the exhaust conduit and the downstream end of the outside protecting pipe. An exhaust device is constituted so that the distance between the end outer periphery of the exhaust conduit and the end inner periphery of the outside protecting tube at the curved pipe portions 32b, 42b gets larger at the opposite side of the curvature centers o1, o2 at the curvature pipe portions 32b, 42b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
