PROBLEM TO BE SOLVED: To provide a dispersion plate which can obtain a high exhaust agitation effect with space-saving.SOLUTION: A dispersion plate 30 is arranged at an exhaust upstream side rather than an oxygen concentration sensor in an exhaust pipe of an internal combustion engine, and has two kinds of plates 31, 32 which are arranged in the exhaust pipe. The first plate 31 has a deflection plate 34 which extends in a direction in which the deflection plate is inclined to an extension direction A of the exhaust pipe, and in a direction in which the deflection plate is distorted, and the second plate 32 has a penetration hole 35, and extends in a direction in which the second plate intersects with the extension direction A. The first plate 31 constitutes a portion of an internal peripheral side of the dispersion plate 30, and the second plate 32 constitutes a portion of an external peripheral side of the dispersion plate 30.SELECTED DRAWING: Figure 2 【課題】高い排気攪拌効果を省スペースで得ることのできる分散板を提供する。【解決手段】分散板３０は、内燃機関の排気管における酸素濃度センサよりも排気上流側に設けられ、排気管内部に設けられた２種類のプレート３１，３２を有する。第１プレート３１は排気管の延設方向Ａに対して傾いた方向且つ捩れた方向に延びる偏向板３４を有し、第２プレート３２は貫通孔３５を有して上記延設方向Ａと直交する方向に延びる。第１プレート３１が分散板３０の内周側の部分を構成し、第２プレート３２が分散板３０の外周側の部分を構成する。【選択図】図２
