PROBLEM TO BE SOLVED: To protect an operator with a simple structure; and to provide a wide rear field of view for the operator. SOLUTION: A left rear pillar 21 of a cab box 16 is arranged on the rear of a driver's seat 13. When the large load acts on the gear box 16, a part near the operator seated in the driver's seat 13 of the cab box 16 surrounding the driver's seat 13 can be effectively reinforced by the left rear pillar 21, and thereby a number of parts constituting the cab box 16 can be reduced, and assembly workability can be improved. Further, the left rear pillar 21 of the cab box 16 is positioned on the rear of the driver's seat 13, the left rear pillar 21 can be removed from the field of view when the operator turns to the back, and the rear field of view can be enlarged.
