Abstract
A curved-pipe portion curved so as to change the exhaust direction is provided to the downstream-side end section of the exhaust guide pipe and the external protective pipe, and the spacing between an end-section outer periphery of the exhaust guide pipe and an end-section inner periphery of the external protective pipe in the curved-pipe portion is configured so as to be greater on the side opposite the center of curvature of the curved-pipe portion than the side nearer thereto.
