PURPOSE:To reduce the weight of the above structure and to facilitate maintenance by forming at least a frame with light alloy-group material and forming the other structural constituent members with iron-group material in a vehicle body structure comprising a roof framing, a side framing, an end framing and a frame. CONSTITUTION:A vehicle body structure comprises a side framing 1 forming the side thereof, a roof framing 10, an end framing (not shown) and a frame 20, wherein the side framing 1 comprises an outer plate 2, a cross frame 4 for supporting the side framing, side poles 7, 8 orthogonal to the cross frame 4 and a reinforcing floating frame 6. The roof framing 10 comprises a roof outer plate 11, a longitudinal member 12 and a circumferential member 13 which reinforce the outer plate 11 and a cantrail 31, and the frame 20 comprises a side beam 21, a cross beam 41 and a keystone 22. In this case, the frame 20 is formed of light alloy-group material such as an aluminium alloy or the like, which is not painted and easy to be washed so as to reduce the weight of the structure. On the other hand, the other structural constituent members are formed of iron-group material. |
