Claims

[Scope of Claim for Utility Model Registration] (1) A driver's cab body consisting of front and rear, left and right outer walls and a ceiling wall, a front glass provided on the front outer wall of the driver's cab body, and the front glass. In the operator's cab of a construction machine, the front guard is attached to the front outer wall via multiple support arms for protection. A protrusion is provided which is bent to protrude forward and extends in the vertical direction, and each of the protrusions is provided with a bolt hole, and each bolt hole is provided with a support arm of the front guard. An operator's cab for construction machinery, characterized in that the construction machine is configured to be fastened with bolts and nuts. (2) The outer wall surface on the front side is divided into two front wall members, and each of the front wall members is bent to protrude forward to form a bent part, and each of the front wall members is bent so as to project forward. The operator's cab of a construction machine according to claim (1), wherein the protruding portion is formed by welding the bent portion using a welding means. (3) The operator's cab of a construction machine according to claim (1), wherein molding members are fitted to the left and right protrusions.
