摘要

An exhaust structure of a straddle-type vehicle capable of taking measures against exhaust heat and exhaust sound even with a configuration where there is only one resonator chamber. A muffler (36) includes: an outer tube (133) constituting an outer circumferential member of the muffler (36); first second separators (151, 153) defining expansion chambers (R1, R2) in the outer tube (133); a body end (155) being provided at the downstream end of the outer tube (133); and glass wool (137) being provided on the inner circumference of the outer tube (133), a resonator chamber (R3) is provided in a most downstream part of the muffler (36) by the outer tube (133), the body end (155), and the second separator (153) being the closest to the body end (155), and the surroundings of the resonator chamber (R3) are surrounded by the glass wool (137).
