PROBLEM TO BE SOLVED: To provide a cab for construction machine which can improve the strength of the cab effectively with a simple structure. SOLUTION: Inside a cab 1, a reinforcing plate 12 is fitted which extends to the right and left, ranging from second pillars 8A, 8B to third pillars 9A, 9B and whose cross section is of roughly U shape. The front and rear parts of the reinforcing plate 12 are tightened against a base plate 10 and a rear inner panel 5 respectively. Bending rigidity from the second pillars 8A, 8B to the third pillars 9A, 9B becomes large, thus it is possible to increase sufficient cab strength against tipping load F. |
