Two locations drawn inward from vehicle-widthwise outside ends in the top part of a back panel (4) of a cab (1) are designated as load support points (A, B), a pair of reinforcing studs (13, 14) are attached to the back panel (4) so as to connect the load support points (A, B) and a floor (9) directly above a pair of rear-side cab mountings (7, 8) supporting the rear part of the cab (1) from a frame (6) side, a reinforcing beam (12) is attached to the back panel (4) so as to connect the top ends of the reinforcing studs (13, 14) together, and the unreinforced parts on the vehicle-widthwise sides of the reinforcing beam (12) remain as impact-absorbing parts (15, 16). |
