Claims

[Scope of utility model registration request]

A rectangular chassis frame consisting of a pair of left and right longitudinally parallel long side members and a plurality of horizontally short cross members each having a channel-shaped cross section, the left and right ends of which are each made of a formed steel plate having a hat-shaped cross section are flat. Each member consists of an atsupa cross member which is riveted to the web portion of the opposing side member with a nearly oblong rectangular abutment surface bent at a right angle downward, and a relatively short formed steel plate having a hat-shaped cross section. The horizontal flange portions are riveted to the lower surfaces of the horizontal flange portions near the left and right ends of the above-mentioned Atsupa cross member, and the center portions extend diagonally downward toward the opposing side members, and are formed at the tip portions, and the upper center portions of the horizontally long rectangles are trapezoidal. A chassis frame structure characterized by comprising a cross member consisting of a pair of left and right lower cross members which are riveted to the web portions of side members facing each other with vertical abutment surfaces having a protruding shape.
