PROBLEM TO BE SOLVED: To enhance the fitting strength of the right and left front pillers and the rear pillers against the base frame when they are fixedly mounted thereon. SOLUTION: Front mounting bases 14, 15 arranged at the lower corners of the cab 11 are formed by base boards 14A, 15A and fitting protrusions 14B, 15B and rear mounting bases 16, 17 are formed with the base boards 16A, 17A and the fitting protrusions 16B, 17B. Meanwhile, notches 22B, 23B in which the fitting protrusions 14B, 15B are fitted, are provided in the front pillers and notches 24A, 25A in which the fitting protrusions 16B, 17B are fitted, are provided in the rear pillers 24, 25. Accordingly, by welding along the joint between the fitting protrusions 14B, 15B, 16B, 17B and the notches 22B 23B, 24A, 25A, the welding distance can be made long to increase the mounting strength. |
