摘要：An exhaust device 40 includes: left and right exhaust pipes 41 L, 41 R; and mufflers 44L, 44R connected to downstream ends of the exhaust pipes 41 L, 41 R. The pair of left and right exhaust pipes 41 L, 41 R respectively includes a merging portion 43L, 43R with a catalyst 48L, 48R provided therein. The pair of left and right exhaust pipes 41 L, 41 R respectively includes, downstream of the catalyst 48L, 48R, a branching portion 55L, 55R which has one side thereof extending to the muffler 44L, 44R, and the other side thereof extending to a connecting pipe 54. An oxygen sensor 52 is provided on a downstream side of one of the pair of left and right branching portions 55L, 55R. The oxygen sensor 52 can detect oxygen in the exhaust gas in a state where the exhaust gas is sufficiently stirred, and this can lead to a reduction in the size of the catalyst.
