する排気ガス浄化装置。 In an exhaust gas purification device in which an oxygen sensor is disposed on the downstream side of a catalytic converter in which a catalyst carrier is housed in a converter case, the outlet side of the converter case is formed into a cone shape whose passage diameter becomes smaller toward the downstream side. An oxygen sensor is provided immediately downstream of the cone portion, and the cone angle of the cone wall surface on the side where the oxygen sensor is provided in the cone portion is made larger than the cone angle of the cone wall surface on the opposite side. Exhaust gas purification device.
