To provide a vehicle body structure equipped with a suspension unit having a shock absorber and a compression coil spring independent of each other, in which the compression coil spring 4 is prevented from dropping off even if a side member shifts.

Inside a compression coil spring 4, a chain 11 is disposed to connect a side member 1 to a suspension member 3. Even if the compression coil spring 4 can not be interposed between the side member 1 and the suspension member 3 by its energizing force, the compression coil spring 4 is held between the side member 1 and the suspension member 3, thus preventing the compression coil spring 4 from dropping off.
