JPS6483814A - Exhaust device in vehicle of motorcycle or the like - Google Patents

Abstract

PURPOSE:To prevent lubricating oil from scattering to the outside by forming a bottom surface, positioned from the upper end of a chamber part to an exhaust outlet, to be tilted to an upper direction, in the case of an exhaust device which interposes in its intermediate part the chamber part tilting to the upper direction drawing its upper end to the rear. CONSTITUTION:An exhaust pipe assembly 13, having an exhaust pipe 14 drawn to the front diagonally in a bottom direction from an exhaust port of an engine, forms this exhaust pipe 14 in its drawn out end crossing with each other in the front of the engine while molding the pipe to be curved in almost a U-shape toward the side. The point end of this curved part 15 is risen up, and this rise up part forms a large contour chamber part 16 swollen in a hollow cylindrical shape. A small contour connection pipe 19, protruding to the rear, is drawn out in the upper end of the chamber part 16, being connected to a rear part exhaust pipe 21. The bottom surfaces of the connection pipe 19, rear part exhaust pipe 21 and a silencer 24 are formed in a tilt surface 31 tilting to an upper direction continuously in accordance with the surface advancing to the side of an exhaust outlet 30.
