Abstract: A vehicle body end structure has a longitudinal frame member connected to a transverse frame member by curved parts to disperse the load when the vehicle undergoes an end (rear or front) collision. In particular, wedge-shaped open spaces exist between the interior surfaces of the transverse frame member and the corresponding wall surfaces of the curved parts that face the interior surfaces. Consequently, when the vehicle undergoes an end collision, the inward collapsing of the transverse frame member causes the curved parts to gradually undergo bending deformation while being folded over such that the curved parts touch against the transverse frame member. Deformation control structures are provided on the curved parts to prevent localized stress concentration from occurring and enable the curved parts to deform in a stable manner. Thus, the curved parts are prevented from undergoing acute bending and the input load is absorbed more efficiently.
