A cab (10) includes a driver's seat (24) for an operator to sit and an air conditioner (23) in its internal space. A floor plate (12) forming the floor includes a tapered portion on a front side with respect to an operator sitting on the driver's seat and a rectangular portion on a rear side with respect to the operator as seen in a plan view, and the tapered portion is in a tapered trapezoidal shape having two parallel sides and a dimension in a width direction decreasing frontward. A through hole (17) is formed in the floor plate (12) of a region of the tapered portion and connects the internal space of the cab (10) and an external space of the cab (10) to each other.
