摘要： On an upper revolving structure, an engine having an exhaust port is mounted. In the midway portion of the exhaust pipe connecting the exhaust port of the engine and an exhaust gas post-treatment device, a first bellows pipe and a second bellows pipe are arranged through a connecting pipe having an L-shaped bending portion. In this case, the first bellows pipe and the second bellows pipe are arranged so as to have a positional relationship in which axis lines thereof (X1-X1, Z1-Z1) cross each other. That is, the first bellows pipe is arranged in a horizontal direction so that its axis line (X1-X1) extends in the left-right direction of the upper revolving structure. The second bellows pipe is arranged so that its axis line (Z1-Z1) matches the vertical direction of the upper revolving structure.
