<P>PROBLEM TO BE SOLVED: To effectively suppress cross-sectional deformation of a frame member at low cost. <P>SOLUTION: Regarding an inner panel 130, rigidity in an angular change of a first corner part K1 and a second corner part K2 is larger than rigidity in an angular change of a third corner part K3. As a result, by the movement of a bottom part 152 of a recess 150 to a neutral axis G side, the angular change of the third corner part K3 is larger than the angular changes of the first corner part K1 and the second corner part K2. The side surface parts 144A, 144B of protrusions 140A, 140B in an outer width direction rotate in a direction toward in an inner width direction (the neutral axis G side) as an arrow J1 shows, and a flange part 132 is pulled in the inner width direction as an arrow J3 shows. Consequently, the deformation of an outer panel reinforce 120 is suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
