Abstract

A vehicle body lower section structure including a battery pack and a pair of rockers is provided. The battery pack is mounted at a vehicle lower side of a floor panel of a vehicle. The pair of rockers are respectively disposed at two outer sides of the floor panel in a vehicle width direction. Each of the rockers extends along a vehicle front-rear direction and is configured with a profile when sectioned along the vehicle width direction that is a closed cross-section profile. Inside each rocker, an impact absorbing section is disposed at a position overlapping with the battery pack in vehicle side view so as to span along the vehicle width direction between an outer wall and an inner wall of the rocker, and a join section is provided at the impact absorbing section, joining the battery pack to the rocker.

Description

technical field [0001] The present disclosure relates to a vehicle body substructure. Background technique [0002] Japanese Patent Application Laid-Open (JP-A) No. H07-117730 discloses a technique for a floor structure of an electric vehicle in which side members are provided at the lower surfaces of both sides of the floor panel in the vehicle width direction, and the door sill (hereinafter referred to as "sill") is provided at the side edge of the floor panel, and the sill and the side member are coupled together by an outrigger. [0003] In JP-A No. H07-117730, a side frame constituting a part of a battery frame (hereinafter referred to as "battery pack") mounted with a plurality of batteries is attached to the lower side of the side member. A support member is provided at an inner wall on a vehicle width direction inner side of each side frame, extends at an inner surface side of the side member, and faces an outer surface of an adjacent battery in the battery pack. ...
