  • Vehicle body structure
    Patent number: 6962389
    Abstract: A vehicle body structure of the present invention comprises a front pillar including a front pillar inner and a front pillar outer and provided in an up and down direction of a vehicle body, a front roof rail provided in an upper portion of the front pillar and extended in a lateral direction of the vehicle body, and a joint member provided between the front roof rail and the front pillar inner and jointing the front roof rail and the front pillar inner. In the vehicle body structure, a joint portion other than a joint portion of the joint member and a side edge portion at a body center side of the front pillar inner is configured to provide weaker joint, with respect to a load applied to the vehicle body obliquely from above, than joint provided by a joint portion of the joint member and the front roof rail. Thereby, the concentration of stress corresponding to the load can be avoided.
