Abstract
A cab includes left and right rear pole members having internal spaces and prescribed shapes in cross-section. The right rear pole member includes a first hole portion that extends along the longitudinal direction of the right rear pole member and penetrates the right rear pole member in the left-and-right direction of the right rear pole member, and a first plate-shaped member inserted into and secured in the first hole portion.
Claims7
A cab comprising:
- left and right rear pole members having internal spaces,
- the right rear pole member including a pair of opposing surfaces aligned in the left-and-right direction of the cab, and including
- a first hole portion that extends along the longitudinal direction of the right rear pole member, the first hole portion being formed in the opposing surfaces to penetrate the right rear pole member in the left-and-right direction of the cab, and
- a first plate-shaped member inserted into and secured in the first hole portion so that the first plate-shaped member extends between the opposing surfaces generally along the left-and-right direction of the cab.

A construction machine comprising:
- a cab that is installed on a revolving frame, the cab including a plurality of pole members having internal spaces;
- and
- a main beam portion that is arranged on the revolving frame,
- one of the pole members that is arranged in proximity to the main beam portion including a pair of opposing surfaces aligned in the left-and-right direction of the cab, and including
- a first hole portion that is formed in the opposing surfaces at a position near the main beam portion, the first hole portion extending along the longitudinal direction of the pole member and penetrating the pole member in the left-and-right direction of the pole member, and
- a first plate-shaped member inserted into and secured in the first hole portion so that the first plate-shaped member extends between the opposing surfaces generally along the left-and-right direction of the cab.
