Abstract: A cab body structure includes a cab front panel 10a, a cab rear panel, a pair of cab side panels 20, and a front window 50a. The pair of cab side panels 20 is arranged almost parallel to each other when width of the cab front panel 10a in the vehicle width direction and width of the cab rear panel in the vehicle width direction are set approximately equal, and arranged slanting on the outer side towards the rear along the vehicle width when width of the cab rear panel in the vehicle width direction is set greater than width of the cab front panel in the vehicle width direction.

Abstract: A reinforcement member 30 integratedly includes a top surface 31, a rear surface 32, a first side 33, and a second side 34. The top surface 31 has an air deflector attaching portion 35. An air deflector arranged on top of a roof panel 2 is attachable to the air deflector attaching portion 35. The second side 34 includes a base 40 and a seatbelt anchor attaching portion 41. The base 40 is formed in approximately the same plane as the first side 33. The seatbelt anchor attaching portion 41 extends inward from the base 40 along the vehicle width and is in contact with a rear pillar inner section. A seatbelt anchor arranged on the inner side of the rear pillar inner section is attachable to the air deflector attaching portion 41.

Abstract: A body side structure 3 includes an outer panel 4 integratedly formed by press forming, an inner panel 5, and a reinforcement 6. The outer panel 4 includes a front pillar outer section 12, and an outer front end lower portion 13 extending downward from the front pillar outer section 12. The inner panel 5 includes a front pillar inner section 26, and an inner front end lower portion 27 extending downward from the front pillar inner section 26. A flange 43 of the reinforcement 6 is joined to the inner front end lower portion 27. A lower edge 23 of the outer front end lower portion 13 is adjacent to or in contact with an outer surface 45 of the flange 43 of the reinforcement 6 at a higher position than a lower edge 36 of the inner front end lower portion 27 and a lower edge 44 of the flange 43 of the reinforcement 6.
