PROBLEM TO BE SOLVED: To provide a shock absorbing apparatus which can satisfy such a severe safety criterion that the maximum acceleration in the forward and backward direction must be at most 20 G when a 1.8 ton car has collided at 60 km/h. SOLUTION: Molten state wires are formed by carrying out the melting extrusion to a thermoplastic resin, and curls or loops are formed on them. A cushioning structure body 40 of a three-dimensional spring structure has large hollow spaces composed of curls or loops randomly formed by bringing neighboring wires into mutual contact with each other. The cushioning structure body 40 and a filling liquid 50 for filling the hollow spaces of the cushioning structure body 40 are enclosed in a partition container 30. A shape holding container 10 is filled with the cushioning structure bodies 40 via a receiving bag 20. COPYRIGHT: (C)2005,JPO&NCIPI
