This vehicle body substructure includes side sill load transmitting members that are provided inside each of side sills, a floor cross-member that is provided on one of an upper surface and a lower surface of a floor panel laid between the side sills and has extending portions extending toward upper portions of the side sill load transmitting members, an underfloor mounting component that is provided below the floor panel and includes an underfloor cross-member, underfloor frames that are attached to lower portions of the underfloor mounting component and the side sills, and underfloor load transmitting members that are provided in the underfloor frames and face the underfloor cross-member. The underfloor load transmitting member has an upper half portion which faces a lower portion of the side sill load transmitting members, and a lower half portion which is fixed to a part of each of the underfloor frames attached to a lower portion of each of the side sills.

Vehicle body substructure

In an automobile body structure, since a floor panel disposed beneath left and right side sills and a battery support frame includes a center tunnel protruding upwardly and extending in the vehicle body fore-and-aft direction, and a main body portion of the battery support frame and the floor panel are connected via a linking bracket, it is possible to reinforce the battery support frame with the floor panel and prevent the battery support frame from warping into an arc shape and being bent by the collision load of a side collision and, moreover, since even if the battery support frame is formed into a straight line shape, interference with the center tunnel can be avoided, it is possible to reliably make the battery support frame buckle when the collision load of a side collision is inputted thereinto, thus enhancing the ability to absorb the energy of a collision.

Automobile body structure

An inner center pillar member has a section passed through the interior of a side sill into outer and inner spaces. An outer load transmitting member is provided within the outer space in opposed relation to the passed-through section of the inner center pillar member, and an inner load transmitting member is provided within the inner space in opposed relation to the outer load transmitting member with the passed-through section interposed therebetween. A door beam provided within a door has a rear end portion located close to the outer load transmitting member and lapped over a corner portion of a center pillar.
