## Abstract

With two points each inward of a vehicle-widthwise outer end of an upper portion of a back panel 4 of a cab 1 being set as load support points A and B, a pair of reinforcing studs 13 and 14 are mounted on the back panel 4 to connect the load support points A and B with a floor 9 directly on paired rear-side cab mountings 7 and 8 for support of a rear of the cab 1 from a frame 6, and a reinforcing beam 12 is mounted on the back panel 4 to interconnect upper ends of the reinforcing studs 13 and 14, unreinforced sections being left as shock absorptive portions 15 and 16 at vehicle-widthwise opposite ends of the reinforcing beam 12.

## Claims

### Claim 1

A cab reinforcing structure, comprising:
a pair of reinforcing studs; and
a reinforcing beam,
wherein with two points each inward of a vehicle-widthwise outer end on an upper end portion of a back panel in a cab by a predetermined length is set as load support points,
wherein the pair of reinforcing studs are mounted on said back panel to connect said load support points with a floor directly on a pair of rear-side cab mountings for support of a rear of said cab from a frame while the reinforcing beam is mounted on said back panel to interconnect upper ends of said reinforcing studs, unreinforced sections being left as shock absorptive sections at vehicle-widthwise opposite ends of said reinforcing beam, and
wherein the load support points are set vehicle-widthwisely outward of an arrangement span of the rear-side cab mountings, respectively, so that the reinforcing studs are arranged to tilt vehicle-widthwisely outward, respectively, as the studs approach a roof panel.
