PROBLEM TO BE SOLVED: To make distortion around stiffeners hard to appear when reinforcing a tail gate (a door for a vehicle) by using the stiffeners. SOLUTION: In this structure, the stiffeners 45 and 46 are locally provided between an inner panel 41 and an outer panel 42 of the tail gate (the door for the vehicle) 24. In the stiffeners 45 and 46, the edge parts 51 and 51 are formed into waveforms 52. Since the edges parts 51 and 51 of the stiffeners 45 and 46 are formed into the waveforms, stress concentrated around the stiffeners 45 and 46 can be dispersed. As a result, generation of distortion at the door for the vehicle around the stiffeners 45 and 46 can be prevented. COPYRIGHT: (C)2004,JPO
