- the left and right pillar members 31a, 31b, 32a, 32b disposed at the four corners of the cap structure 20 are formed of a pipe material. For this reason, the rigidity of the cap can be greatly improved as compared with a conventional cap structure formed by combining sheet metal members.
- the left front column member 3 la has a rectangular cross-sectional shape
- the right front column member 3 lb has a modified cross-sectional shape for fitting a window glass or the like.
- the left front pillar member 31a is formed by bending a pipe material in the vicinity of the center portion, and a pillar part 31aa arranged along a substantially vertical direction, and a substantially horizontal direction. It has 3 lab beams. In this way, by bending one pipe member to form the column portion 3 laa and the beam portion 31ab, it is possible to obtain a highly rigid cap structure 20 while reducing the number of parts. The same applies to the right front pillar member 3 lb.
- the left rear column member 32a is formed of a single pipe member, and is disposed along a substantially vertical direction.
- the left rear column member 32a has a notch formed in the upper end portion so as to match the shape of the rear beam member 33 to be joined. And the side surface of the rear beam member 33 are joined.

- the cap structure of the present invention can ensure the rigidity of the cap structure even when the plurality of column members constituting the cap structure include the column members without reaching the floor frame. Therefore, it can be widely applied to the cab of work machines such as construction machines and agricultural machines.
