PROBLEM TO BE SOLVED: To provide an exhaust structure of a saddle-riding type vehicle capable of taking a measure against exhaust heat and exhaust noise even in a constitution having only one resonator chamber.SOLUTION: A muffler 36 includes an outer cylinder 133 configuring an outer peripheral member of the muffler 36, first and second separators 151, 153 defining expansion chambers R1, R2 in the outer cylinder 133, a body end 155 disposed at a downstream end of the outer cylinder 133, and glass-wool 137 disposed on an inner periphery of the outer cylinder 133. A resonator chamber R3 is disposed at a most downstream portion of the muffler 36 by the outer cylinder 133, the body end 155, and the second separator 153 closest to the body end 155, and the circumference of the resonator chamber R3 is surrounded by the glass-wool 137.SELECTED DRAWING: Figure 3 |
