PROBLEM TO BE SOLVED: To improve work environment in a cab by surely shielding the cab from a heat exchanger by simple operation in a simplified structure. SOLUTION: A barrier wall 37 is provided on the inside end 29A of a front partition plate 29 of the motor-driven heat exchanger 28 facing a rear surface 21B of the cab 21 so as to shield the clearance 30 between the front partition plate 29 and a left reinforcing vertical plate 8. Thus, the clearance 30 that makes a channel to circulate cooling wind heated through the heat exchanger 28 toward the cap 21 can be shielded by the barrier wall 37. Then the barrier wall 37 can be formed by a small sheet body and easily attached to the front partition plate 29 since it is provided by the use of the front partition plate 29. The clearance 30 in a slight extent can be surely shielded by the barrier wall 37 to suppress a temperature rise or noise such as wind roar, improving the work environment.
