An operator's cab in a construction machine comprising:
- a base plate that defines a bottom portion of the operator's cab;
- a first pair of pillars standing at a left side surface and a right side surface of the operator's cab at a rear side of the operator's cab;
- a second pair of pillars standing at the left surface and the right side surface at an intermediate position between the rear side and a front side of the operator's cab;
- and
- a frame reinforcement member that is provided in space above the base plate, is a member independent from the base plate, extends between the first pair of pillars and extends between the second pair of pillars, so as to create a resistance against a bending load applied to the pillars.
