An intake hole (17A) of a first exhaust gas post-processing device (16) is provided opposite to an engine (8) across an axis (O1-O1) of a cylinder body (17) of the first exhaust gas post-processing device (16). An exhaust pipe (26) connecting the engine (8) to the first exhaust gas post-processing device (16) comprises: a horizontal pipe path (27) extending in the left-and-right direction of an upper rotating body (3) in front of the first exhaust gas post-processing device (16), the horizontal pipe path (27) having, in the middle thereof, a bellows tube (28) for absorbing relative change in position between the engine (8) and the first exhaust gas post-processing device (16); and a bent pipe (29) bent in a U-shape from a tip of the horizontal pipe path (27) towards the rear, the bent pipe (29) being connected to the intake hole (17A) of the first exhaust gas post-processing device (16). |
