Claim:
A cab body structure comprising: a cab front panel; a cab rear panel arranged facing behind of the cab front panel; a pair of cab side panels, having front ends, which are connected to respective ends of the cab front panel in a vehicle width direction, back ends, which are connected to respective ends of the cab rear panel in the vehicle width direction, and door openings, which are formed between the front ends and the back ends, respectively, and forming a connecting angle with the cab front panel which is determined according to a difference between a width of the cab front panel in the vehicle width direction and a width of the cab rear panel in the vehicle width direction, a front window, which is attached to a front window opening partitioned into an upper edge of the cab front panel and front edges of the cab side panels; and connection auxiliary components which connect the cab front panel and each of the cab side panels, and are formed in a shape which varies according to the determined connecting angle formed between the cab front panel and each of the cab side panels, wherein the pair of cab side panels is arranged almost parallel to each other and forms a first connecting angle with the cab front panel, when a width of the cab front panel and a width of the cab rear panel in the vehicle width direction are set approximately equal in a first vehicle, arranged slanting on an outer side from the cab front panel toward the cab rear panel as seen in the vehicle width direction and forms a second connecting angle, different from the first connecting angle, when the width of the cab rear panel is set greater than the width of the cab front panel in the vehicle width direction in a second vehicle, and the connection auxiliary components are formed in a first shape according to the first connecting angle determined for the first vehicle and in a second shape, different from the first shape, according to the second connecting angle determined for the second vehicle.
