PROBLEM TO BE SOLVED: To provide a vehicle body frame structure capable of distributing a shock load and efficiently damping the shock load when releasing the shock load inputted to a front side frame from a kick-up part to the back side. SOLUTION: The kick-up part 12b formed on a rear end part of the front side frame 12 is joined to both sides of a center tunnel 16 formed on a toe board 2, and the kick-up part 12b and a ridge part 18a of the center tunnel 16 are connected to each other via a third sub frame 23. The shock load, which is inputted to the front side frame 12 upon the front surface shock and is transmitted to the kick-up part 12b, is distributed to the center tunnel 16 by the third sub frame 23, and then the shock load is released backward along a wall surface of the center tunnel and is damped.
