Abstract
A dispersion plate that can be arranged on an upstream side of an oxygen concentration sensor in an exhaust pipe of an internal combustion engine, the oxygen concentration sensor being arranged in the exhaust pipe, is provided. The dispersion plate is configured to disperse an exhaust flow in the exhaust pipe. The dispersion plate includes a first plate and a second plate. The first plate includes a deflection plate that extends in an inclined direction and a twisted direction with respect to an extending direction of the exhaust pipe. The second plate extends in a direction orthogonal to the extending direction of the exhaust pipe. The second plate includes a through hole. The second plate is arranged on an outer circumferential side of the first plate in the exhaust pipe.
