PROBLEM TO BE SOLVED: To securely support an exhaust gas post-processing device with sufficient rigidity.SOLUTION: A post-processing device fitting frame 20 comprises a front fitting leg 21, a rear fitting leg 24, and a frame 27 which connects the front and rear fitting legs 21 and 24 to each other. A longitudinal leg part 22 of the front fitting leg 21 is fitted to a front longitudinal leg part fitting plate 5F of a right front projection beam 5E2, and a lateral leg part 23 is fitted to a front lateral leg part fitting plate 5M of a right front engine support bracket 5K. A longitudinal leg part 25 of the rear fitting leg 24, on the other hand, is fitted to a rear longitudinal leg part fitting plate 5G of a right rear projection beam 5E3, and a lateral leg part 26 is fitted to a rear lateral leg fitting plate 5N of a right rear engine support bracket 5L. Consequently, the post-processing device fitting frame 20 is fitted tightly to a swivel frame 5 in a four-point support state, so that an exhaust gas post-processing device 13 which is heavy can be supported with sufficient rigidity. |
