Abstract
A load transmission portion which projects toward a roof rail outer panel is provided at a position between the roof rail outer panel and a roof rail inner panel which is located substantially at the same longitudinal-position as an upper end of a pillar outer panel. Accordingly, a center pillar can be properly restrained from coming into a vehicle compartment, restraining any improper increase of the number of components.
Claims20
A side vehicle-body structure of a vehicle, comprising:
- a pair of right-and-left roof rails extending in a vehicle longitudinal direction at an upper portion of a vehicle body, each of the roof rails being formed integrally by a roof rail outer portion provided on an outward side and a roof rail inner portion provided on an inward side;
- a roof reinforcement extending in a vehicle width direction and connecting the pair of right-and-left roof rails;
- a pair of right-and-left side sills extending in the vehicle longitudinal direction at a lower portion of the vehicle body;
- and
- a center pillar connecting a central portion, in the vehicle longitudinal direction, of each of the roof rails and a central portion, in the vehicle longitudinal direction, of each of the side sills, the center pillar being formed integrally by a pillar outer portion which is connected to the roof rail outer portion of the roof rail at an upper end thereof and a pillar inner portion which is connected to the roof rail inner portion of the roof rail at an upper end thereof,
- wherein a load transmission portion is provided at a position between said roof rail outer portion and said roof rail inner portion which is located substantially at the same longitudinal-position as the upper end of said pillar outer portion, an upper end of the load transmission portion being connected to an outward face of the roof rail inner portion, a lower end of the load transmission portion being connected to the upper end of said pillar inner portion or the outward face of the roof rail inner portion, the load transmission portion having a projection that projects outward toward the roof rail outer portion, said projection being positioned in an inner space of the roof rail.
