Kind Code:

A1

Abstract:

[Problem] The objective of the present invention is to provide a technology with which it is possible, in a exhaust device provided with an oxygen sensor, for oxygen contained in an exhaust gas to be measured more accurately. [Solution] In an exhaust device provided with a silencer 32 coupled downstream of an exhaust tube 31, a catalyst which cleans the exhaust gas is provided in the exhaust tube, and an oxygen sensor 80 is attached to a pipe portion 64 which is downstream from the catalyst and is directly coupled to the catalyst. The oxygen sensor 80 is provided substantially perpendicular to the axial direction of the pipe portion 64 through which the exhaust gas flows. The oxygen sensor 80 includes a detecting portion 82, the detecting portion 82 is disposed in a recessed portion 81 formed in the silencer 32, and a wire 83 is disposed outside the recessed portion 81.
