Therefore, the energy absorption characteristics are excellent for a relatively small collision energy. In addition, when the collision energy acting on the hollow panel 1 is large, the collision energy causes the deformation of the hollow panel 1, the compression deformation of the foam 25, and the deformation of each transverse frame portion 31 and the vertical frame portion 32 of the reinforcing frame body 30. It is absorbed by each breakage. Particularly, the reinforcing bone body 30 is formed of the foam 2
Since it is damaged while being covered inside 5, the reinforcing bone body 30
Even after the breakage, the frictional force generated between the foam 25 and the reinforcing skeleton 30 is applied and the collision energy can be absorbed. As a result, it is possible to prevent the problem that the energy absorbing function is extremely deteriorated immediately after the reinforcing bone body 30 is broken, and the energy absorbing characteristic is excellent even for a large collision energy.

In, the reinforcing bone body 230 of the foam filling tool 210 is constituted by a plurality of rod-shaped vertical bone portions 232 extending over substantially the entire length of the internal filling region of the hollow panel. In addition, the foamable base material 220 is foamed by external heating to become a foam and is foam-filled over substantially the entire inner filling region, and is divided into a plurality of plates in the longitudinal direction of the inner filling region. The foamable base material 220a is used. Then, a hole through which the plurality of rod-shaped vertical bone portions 232 is inserted is formed in each of the plurality of divided foamable base materials 220a. That is, in the third embodiment, the foam filler 210 is configured by inserting and integrating a plurality of rod-shaped vertical bone portions 232 into the holes of the plurality of divided foamable base materials 220a. .
