    Abstract: 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.

    Abstract: To increase an effect of absorbing an impact load from a vehicle front side. A vehicle-body structure includes a left-side suspension support member supporting a front suspension, a center frame disposed higher than and away from a floor panel at a vehicle-width-direction central portion of an occupant space and extending in a vehicle front-rear direction, a left-side front frame connected to a front portion of the center frame and extending to the left-side suspension support member, a right-side front frame connected to the front portion of the center frame and extending to a right-side suspension support member, and a connection member that connects the floor panel and at least one of a rear portion of the left-side front frame, a rear portion of the right-side front frame, and the front portion of the center frame.

    Abstract: A vehicle-body structure both protects a battery and provides a routing member below a floor panel that improves underfloor aerodynamic performance. Embodiments of a vehicle-body structure may include: a routing member that extends in a vehicle front-rear direction on a vehicle-width-direction outer side of a battery frame below a floor panel; a cover member that extends from a lower side of a battery to a lower side of the routing member; battery-frame fixation portions that fix the battery frame to side sills; and cover-member fixation portions that fix a vehicle-width-direction end portion of the cover member to the side sills. The routing member and the battery-frame fixation portions may be positioned on a vehicle-width-direction inner side of the cover-member fixation portions.

    Abstract: To suppress vibration and noise due to load input from a rear suspension device, a left-side load input portion that is fixed to a left-side rear-side frame and to which a load from a rear suspension device is input, and a right-side load input portion that is fixed to a right-side rear-side frame and to which a load from a rear suspension device is input are provided. A cross member is provided at a position lower than the left-side load input portion and the right-side load input portion to which loads from the rear suspension devices are input. The cross member and the left-side load input portion are connected through a left-side rear connection frame. The cross member and the right-side load input portion are connected through a right-side rear connection frame.

    Abstract: A vehicle body rear part structure for a vehicle includes a side frame, a subframe disposed below the side frame, and a vehicle body frame member disposed on a middle side in the vehicle body front-rear direction with respect to the subframe. The vehicle body frame member includes: a vertical frame offset outwardly in the vehicle width direction with respect to the subframe; and a lateral frame extending inwardly in the vehicle width direction from the vertical frame. A connecting portion is provided on the subframe. The connecting portion includes: an inclined portion extending while being inclined outwardly in the vehicle width direction, to face the vertical frame; and a widening portion widening inwardly in the vehicle width direction up to a position where the connecting portion linearly extends in the vehicle body front-rear direction from the inclined portion, to face the lateral frame.
