A cab, placed on a rotation frame, has a right rear pillar (34) placed close to an installation section (3a) which is a part of the rotation frame. A reinforcement structure (20) formed by combining holes (34a) and plates (21a) is provided at that portion of the right rear pillar (34) which is close to the installation section (3a). To form the reinforcement structure (20), the plates (21a) are inserted and fixed to the holes (34a) which are formed to penetrate a wall surface of the pipe-shaped right rear pillar (34). |
