Abstract
Provided is a cab for construction machine, having an excellent operator protection effect against a lateral load. Provided is a cab disposed on an upper frame of a construction machine, including a pair of rear pillars and a rear panel disposed therebetween. The rear panel includes an outer panel and an inner panel including a plurality of panel portions vertically arranged and a bridge portion partly bridging the panel portions vertically adjacent to each other at a position offset from a lateral center position of the rear panel. The bridge portion forms a low-strength portion having lower strength than that of the panel portions so as to make the low-strength portion include a bending point at which the rear panel is bent when a lateral load acts thereon through an outer rear pillar.
