PROBLEM TO BE SOLVED: To make uniform a circulation quantity of exhaust gas per unit time among cylinders of a multicylinder engine and bring the exhaust gas into contact with an exhaust gas sensor.SOLUTION: An exhaust device comprises guide fins 15 each formed such that an edge, which is farther from an air-fuel ratio sensor 11, of an opening portion 8 is longer than an edge thereof closer to the air-fuel ratio sensor 11, the guide fins 15 guides exhaust gas to the air-fuel ratio sensor 11 and make uniform a flow velocity of the exhaust gas of each cylinder.SELECTED DRAWING: Figure 2 |
