PROBLEM TO BE SOLVED: To provide a floor structure of a vehicle body which can relax the joining accuracy of both reinforcing members when a width direction reinforcing member is joined with a forward and backward direction reinforcing member. SOLUTION: The floor structure of the vehicle body comprises the forward-backward direction reinforcing member 10 which elongates on the floor F in the forward-backward direction of the vehicle body and forms a closed cross section by connecting an inside member 11 and an outside member 12, and the width direction reinforcing member 20 which elongates on the floor F in the direction of the vehicle width. Ends of the width direction reinforcing member 20 in the direction of the vehicle width are connected to the inside member 11 of the forward and backward direction reinforcing member 10. A joining error absorbing portion 30 for absorbing a joining error between the forward-backward direction reinforcing member 10 and the width direction reinforcing member 20 is provided between the inside member 11 and the outside member 12 at a position where the width direction reinforcing member 20 is arranged. By this configuration, the joining error is absorbed by the joining error absorbing portion 30, and the positional change of a body side BS in the direction of the vehicle width can be reduced.
