To provide a vehicle body structure capable of improving impact energy absorption ability through appropriate deformation of the structure, and capable of appropriately transmitting a load rearwardly of the vehicle body.
An angle change permitting part 30 is formed in a top wall 13. The angle change permitting part 30 can reduce the strength in a twisted area B opposing a connection 21. When a lower arm 3 collides with the twisted area B, the top wall 13 breaks along breaking lines L1, L2 with notches 31, 33 and through holes 32, 34 as a start. The top wall 13 deforms so as to twist in the twisted area B. Thereby, a change in mounting angle of the connection 21 is permitted and breaking deformation of the lower arm 3 is permitted. When the load F acts on, the lower arm 3 sufficiently deforms to obtain the retreating amount. Furthermore the lower arm 3 deforms without any interference so as to collide with a bracket 5.
