Vehicle body structure

A vehicle body structure comprising:

• a dash lower panel for partitioning a power source device chamber and a vehicle compartment;
• a dash cross member provided on the dash lower panel and constituting a closed cross-section extending in a vehicle width direction;
• a tunnel member provided at a central portion in the vehicle width direction of the dash lower panel and extending in a front-rear direction in a groove shape opening downwardly;
• a vertical member extending upwardly from a front end of the tunnel member and joined to the dash lower panel;
• left and right upper lateral members extending outwardly in the vehicle width direction from the vertical member and joined to the dash lower panel;
• and
• a front side frame extending in the front-rear direction in the power source device chamber and having a rear end joined to the dash lower panel, wherein
• the dash cross member has a convex shape with a central portion located forward of both ends in the vehicle width direction in plan view,
• the tunnel member has a tunnel closed cross-sectional portion constituting a part of the central portion of the dash cross member, a front fragile portion provided in front of the tunnel closed cross-sectional portion, and a tunnel main body provided behind the tunnel closed cross-sectional portion,
• the front fragile portion has a compressive strength that is lower than a compressive strength of the tunnel main body against a load from front, and
• at least one of outer ends in the vehicle width direction of the upper lateral members overlaps the rear end of the front side frame in the vehicle width direction.
