A vehicle body side structure is provided where an exhaust apparatus is located on the vehicle-width-direction outer side relative to a side sill without widening the vehicle. Embodiments include an internal combustion engine equipped on the front side of a partition wall defining a front edge of a vehicle cabin space, an exhaust apparatus through which exhaust gas exhausted from the internal combustion engine passes, and a side sill extending along the vehicle front-rear direction on the side of a floor forming a floor surface of the vehicle cabin space. The side sill has a recess having a cross section recessed toward the vehicle-width-direction inner side from the vehicle-width-direction outer side in a cross-sectional view orthogonal to the vehicle front-rear direction and extending in the vehicle front-rear direction, and an exhaust system member provided in the exhaust apparatus is disposed at the recess.

A vehicle-body structure prevents a submarine phenomenon of a passenger during a front-end collision and achieves lowering of the vehicle floor-height while maintaining a sufficient number of mounted batteries. Embodiments of a vehicle-body structure include a seat pan that is formed at part of a floor panel and on which a seat cushion is placed, and a battery arranged below the seat pan. A bulging portion that bulges upward is formed at a vehicle front-side of the seat pan. An accessory member is housed inside the bulging portion. An upper-end portion of the accessory member housed in the bulging portion 4 is positioned farther on the upper-side than a lower-end portion of the bulging portion 48a.

A rear portion of a vehicle body includes a front floor panel, a rear floor panel, a pair of left and right side sills, and a front cross plate. The rear floor panel has a higher upper surface height than the front floor panel. The front cross plate connects a rear portion of the front floor panel and a front wall of the rear floor panel, and an outer end portion in a vehicle width direction is coupled to the left and right side sills. The front wall of the rear floor panel has a plurality of bent corner portions having a side view shape bent in a substantially L shape. At least one of the bent corner portions constitutes a closed cross section extending along the vehicle width direction together with the front cross plate in a vertical height range of the left and right side sills.

Motor vehicle body structure (3), comprising, on each lateral side: a rocker panel beam (15) forming an internal space of the beam (15); and a longitudinal reinforcement (21) positioned in the interior space of the beam (15); the longitudinal reinforcement (21) extending from a centre pillar (9) to an A-pillar (7) and having an angled front portion (25) housed in the A-pillar (7).

An underbody structure of a vehicle includes a cross member, a side sill, and a gusset. The cross member is provided on a floor panel and extends in a vehicle width direction. The side sill is coupled to an outer end of the floor panel in the vehicle width direction and extends in a front-rear direction. The cross member and the side sill are separated in the vehicle width direction. The gusset is interposed between them. The gusset includes front and rear side walls, an upper wall, a protrusion, and front and rear flanges. Each side wall includes a lower end coupled to an outer end of the cross member in the vehicle width direction. The upper wall is coupled to an upper end of each side wall. The protrusion is provided at an outer end of the upper wall in the vehicle width direction.

A vehicle body structure and a vehicle are provided. The vehicle body structure includes a front longitudinal beam, a front compartment crossbeam, and a floor front crossbeam. The front longitudinal beam includes a left front longitudinal beam and a right front longitudinal beam that are disposed at an interval in a transverse direction. The front longitudinal beam is provided with a body section and a downward bent section connected to a rear end of the body section. The front compartment crossbeam is connected to the downward bent section of the left front longitudinal beam and the right front longitudinal beam, and is at least partially located below the body section. The floor front crossbeam is located behind the front compartment crossbeam at an interval, and is connected to the front longitudinal beam.

A crossmember and a manufacturing method for a crossmember is disclosed. The crossmember is made of a metal sheet having a given sectional shape, configures a part of a vehicle body frame, extends along a vehicle width direction, and has an engine mount attaching portion provided in a part of an upper plate portion. The crossmember has an upper crossmember that is made of a single metal sheet extending along the vehicle width direction, the upper crossmember having a larger thickness in a region including the engine mount attaching portion of the upper plate portion and a surrounding area of the engine mount attaching portion compared to a thickness of a remaining region.

A vehicle body lower structure may comprise: a rocker arranged at a lower lateral part of a vehicle body; a power supply package arranged under a floor panel of the vehicle; a first energy absorbing member fixed to a lateral side of the power supply package; and a second energy absorbing member being adjacent to the first energy absorbing member in a vehicle-width direction of the vehicle body, the second energy absorbing member being located outside the first energy absorbing member in the vehicle-width direction of the vehicle body. The first energy absorbing member may include a first protrusion protruding outward in the vehicle-width direction, the second energy absorbing member may include a second protrusion protruding inward in the vehicle-width direction, and the first protrusion and the second protrusion may overlap each other as seen along an up-down direction and are fixed together to the rocker by a bolt.

A vehicle body lower structure may include: a hollow rocker arranged at a lower lateral part of a vehicle body and extending along a front-rear direction of the vehicle body; a power source arranged adjacent to the rocker; an energy absorbing member connected to the power source and arranged under the rocker; and a collar arranged between the rocker and the energy absorbing member. The rocker may be provided with a flange extending downward from a bottom plate of the rocker. A height of the collar above the energy absorbing member may be greater than a height of the flange.

A lower vehicle-body structure of a vehicle may include: a floor panel; a side sill; and a frame member that extends in the front-rear direction on the vehicle-width-direction inner side of the side sill and includes a front-rear extended portion that is in abutment against the side sill on the vehicle-width-direction inner side and extends in the vehicle front-rear direction along the side sill. The front-rear extended portion may include: a bottom face portion; an inner wall portion; and an inner-side flange that extends to the vehicle-width-direction inner side from a distal end portion of the inner wall portion and is joined to the floor panel. Deformation facilitating facilitators that facilitate deformation of the bottom face portion in the vehicle width direction when a collision load in the vehicle width direction is input may be formed in the bottom face portion.
