Abstract
A vehicle body structure includes a resin floor part provided with a flange portion bent toward an upper side or a lower side at an end in a vehicle width direction, and a metal side sill part joined to the flange portion of the floor part. The side sill part includes a rim portion, a peak portion, and intermediate portions that link the rim portion to the peak portion. The peak portion and the intermediate portions form a protruding portion projecting from the rim portion toward the floor part. The flange portion of the floor part is joined to the peak portion of the protruding portion.

A vehicle body structure comprising:
- a resin floor part including a bottom wall and a flange portion bent toward an upper side or a lower side at an end in a vehicle width direction of the bottom wall;
- and
- a metal side sill part joined to the resin floor part at the flange portion, wherein
- the side sill part includes a rim portion, a peak portion, and an intermediate portion linking the rim portion to the peak portion,
- the peak portion and the intermediate portion form a protruding portion projecting from the rim portion toward the floor part,
- the flange portion of the resin floor part is joined to the peak portion of the protruding portion,
- the peak portion to be joined to the flange portion includes a inclined wall that is inclined relative to a vertical direction, and
- the flange portion and a bent portion formed between the bottom wall and the flange portion are in close contacted directly with the inclined wall and joined to the inclined wall by an integral molding of the floor part and the side sill part.
A method for manufacturing a vehicle body comprising:
- a part disposing step of disposing a metal side sill part into a mold;
- a resin supplying step of supplying a resin-containing material into the mold;
- and
- a pressure molding step of molding the resin-containing material into a floor part provided with a flange portion bent toward an upper side or a lower side at an end in a vehicle width direction by applying a pressure to the resin-containing material in the mold, and joining the flange portion of the floor part to the side sill part,
- the side sill part includes a protruding portion protruding from a rim portion toward the floor part, a peak portion of the protruding portion configured to be joined to the flange portion and located away from the rim portion to the floor part side is inclined relative to a vertical direction, and
- a pressure in an up-down direction is applied to the inclined peak portion in the pressure molding step.
