Claims

[Scope of utility model registration request]

A side with a trunnion base protruding from the lower surface of the joint between the vertical side frame with a channel-shaped cross-section and the horizontal cross-member with a cross-section in order to support leaf springs for rear biaxial support. The frame structure has a vertical mounting surface that contacts the inner surface of the web portion of the side frame and a horizontal mounting surface that contacts the upper surface of the lower flange portion of the cross member, and is fixed to the side frame and the cross member via a plurality of bolts. a trunnion base bracket, a recess that is press-worked entirely on the outer surface of the side frame at a portion corresponding to the vertical mounting surface of the trunnion base bracket or partially at each bolt hole, and an upper end mounting A side frame structure for a rear two-axle vehicle body, comprising a trunnion base whose surface is fixed to the horizontal mounting surface of the trunnion base bracket with bolts.
