Abstract

A rocker structure includes a closed cross-sectional part that extends along a vehicle front-rear direction on the outer side of a floor panel of a vehicle in a vehicle width direction, a horizontal plate, and a first vertical plate. The closed cross-sectional part includes an outer wall, an inner wall, a lower wall, and an upper wall. The horizontal plate has a ridge and a valley, and is propped along the vehicle width direction between the outer wall and the inner wall, and the ridge and the valley are provided alternately along the vehicle width direction. The ridge protrudes upward in the vehicle-height direction, and the valley is depressed downward in the vehicle-height direction. The first vertical plate is propped along the vehicle-height direction between the horizontal plate and one of the lower wall and the upper wall.

Dependent claims

A rocker structure comprising:

a closed cross-sectional part that extends along a vehicle front-rear direction on an outer side of a floor panel of a vehicle in a vehicle width direction, the closed cross-sectional part including an outer wall located on an outer side of the closed cross-sectional part in the vehicle width direction, an inner wall located on an inner side of the closed cross-sectional part in the vehicle width direction, a lower wall located on a lower side of the closed cross-sectional part in a vehicle-height direction, and an upper wall located on an upper side of the closed cross-sectional part in the vehicle-height direction;
a horizontal plate that is provided inside the closed cross-sectional part so as to be propped along the vehicle width direction between the outer wall and the inner wall, and has a ridge protruding upward in the vehicle-height direction and a valley depressed downward in the vehicle-height direction that are provided alternately along the vehicle width direction;
and
a first vertical plate that is provided inside the closed cross-sectional part so as to be propped along the vehicle-height direction between the horizontal plate and one of the lower wall and the upper wall.
