EXHAUST PIPE OF CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To prevent the generation of high stress in both end portions of an exhaust pipe and prevent the resonance of the exhaust pipe with an engine.SOLUTION: A construction machine exhaust pipe (5) connecting an engine (3) to an exhaust-gas post-treatment device (4), comprises: a first pipe (8); a second pipe (9); a plurality of bellows (6a, 6b, 6c) disposed between the first pipe (8) and the second pipe (9); and coupling pipes (7) disposed among the bellows (6a, 6b, 6c). The first bellows (6b) is formed such that a peak in an end portion of the first bellows (6b) connected to the first pipe (8) is lower than peaks in the other portions, and the second bellows (6c) is formed such that a peak in an end portion of the second bellows (6c) connected to the second pipe (9) is lower than peak in the other portions.
【課題】排気管の両端部に高い応力が発生するのを防止すると共に、排気管がエンジンと共振するのを防止する。【解決手段】エンジン（３）と排気ガス後処理装置（４）との間を繋ぐ建設機械の排気管（５）であって、第１配管（８）と、第２配管（９）と、第１配管と第２配管との間に配置される複数のべローズ（６ａ，６ｂ，６ｃ）と、複数のべローズの間に配置される繋ぎ配管（７）と、を備える。第１ベローズ（６ｂ）は、第１配管と接続される側の端部の山の高さがそれ以外の部分の山の高さより低い形状を成し、第２ベローズ（６ｃ）は、第２配管と接続される側の端部の山の高さがそれ以外の部分の山の高さより低い形状を成す。【選択図】図４
