PROBLEM TO BE SOLVED: To provide an exhaust structure of an internal combustion engine which is hard to generate strong stress concentration on a fixing member fixing a plurality of exhaust pipes.SOLUTION: An exhaust structure of an internal combustion engine is equipped with a plurality of exhaust pipes and a fixing member. The fixing member is equipped with a first plate 100A and a second plate fixed to the plurality of exhaust pipes. The second plate is inserted in a slit 110 formed on the first plate 100A to unit the first plate 100A and the second plate. The slit 110 includes an opening end portion 111 which opens to one of a first side 101 and a second side 102 of the first plate 100A, and an intermediate end portion 112 formed between the opening end portion 111 and the other of the first side 101 and the second side 102. The plurality of exhaust pipes is fixed to a part on the opposite side to a center line 110C on the first plate 100A. The first plate 100A includes a hole 120 formed so as to connect to the intermediate end portion 112 and having a diameter D longer than the width W of the slit 110.SELECTED DRAWING: Figure 3

    【課題】複数の排気管を固定する固定部材に強い応力集中が生じにくい内燃機関の排気構造を提供する。【解決手段】内燃機関の排気構造は、複数の排気管と固定部材とを備える。固定部材は、複数の排気管に固定された第1プレート100Aおよび第2プレートを備える。第1プレート100Aに形成されたスリット110に第2プレートが挿入されることにより第1プレート100Aと第2プレートとが結合される。スリット110は、第1プレート100Aの第1辺101および第2辺102の一方に開口する開口端部111、および、開口端部111と第1辺101および第2辺102の他方との間に形成された中間端部112を含む。複数の排気管は、第1プレート100Aにおいて中心線110Cに対して反対側の部分に固定される。第1プレート100Aは、中間端部112と繋がるように形成されスリット110の幅Wよりも長い直径Dを有する孔120を含む。【選択図】図3
