PROBLEM TO BE SOLVED: To enhance safety by effectively reinforcing buckling strength of a floor panel including floor members, by arranging a collision energy receiving plate in the rear of a cab front structure, and supporting this receiving plate in rear parts of the respective floor members via beams extening in the longitudinal direction. SOLUTION: In a floor panel 3 of a cab such as a truck, a floor surface of a front part 3a including an installing part of a seat is formed low, a floor surface 3c of a rear part is formed high via a floor surface 3b of an inclining intermediate part, and floor members 1 for forming a closed cross-sectional skeleton are arranged so as to extend in the longitudinal direction along an under surface of this floor panel 3. In this case, beams 2a, 2b are arranged to extend so as to form an almost horizontal strut forward in the almost same height position as the rear floor surface 3c of the floor panel 3 from an intermediate part 1b extending while being vertically offset along the floor panel 3 of the respective floor members 1. The respective rear ends are joined to the intermediate part 1b of the floor members 1, and the front ends are joined to a collision energy receiving plate 5.
