<P>PROBLEM TO BE SOLVED: To provide a reinforcing metallic material for an internal corner part which can be installed in a space-saving manner, improve the deformation performance of bellows, and have excellent energy absorbing performance and a compact body. <P>SOLUTION: The reinforcing metallic material 1 for the internal corner part includes a bent plate portion 4 bent in a wave-shape in which crest portion 4a and trough portions 4b are repeated, and formed in the bellows-shape capable of expansion/contraction deforming; and a pair of mounting piece portions 6 integrally formed at both ends in an expanding/contracting direction of the bent plate portion respectively through flat plate portions 5. The reinforcing metallic material 1 is installed at the internal corner portions 3 of two structure materials 2 so as to respectively join the mounting peace portions 6 making the pair to the structure materials. While reinforcing the internal corner portions, when a load exceeding a predetermined load is inputted between those structure materials, the bent plate portion expansion/contraction deforms to absorb the input load. The bent plate portion is bent and formed so as to come close one side on a surface 5c side to the flat plate portions 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
