PROBLEM TO BE SOLVED: To improve a reinforcing effect without changing a skeleton member and a member of a reinforce at the inside thereof. SOLUTION: The amplitude of a buckling mode waveform of the reinforce 72 inside an outer material 71 is set smaller than the outer material of a hollow section constituting a side member extension 70. As a result, an interference of a deformation mode is generated in the longitudinal direction between the outer material 71 and the reinforce 72 to disperse deformation. COPYRIGHT: (C)2004,JPO
