Abstract: 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.

Abstract: A slab transport tire roller includes a tire which is diminished in thermal stress. A tire assembly disposed at each of outer peripheral portions of a pipe for passing cooling water therethrough includes the tire adapted to contact a slab, support members connecting the tire to the pipe, and rotation preventing means engaging the tire with the support members to render the tire rotatable with the support members.
