A car body structure comprises the following units: a crossbeam with a hat section jointed with the top surface of a base plate, and the crossbeam is jointed with the inner side wall of a side beam in the car width direction; a seat mount rack matched with the side beam inner side wall on the end portion of the crossbeam so as to form a box unit; a reinforcing member configured below the crossbeam and extending on the upper wall of the crossbeam; a joint portion formed by clamping the crossbeam so as to connect the seat mount rack with the reinforcing member. The top of the reinforcing member outer side is formed to leave a regulated distance from the side beam inner wall to the car inner side under the seat mount rack; Accordingly, it is possible to prevent the fuel tank from being damaged under the floor and to prevent the damage prevention structure without reducing the indoor space of the vehicle even if the cross member is deformed downward to V-shaped or the like due to the collision load of the vehicle side impact.
