Abstract: This invention concerns a shock absorbing material placed between two objects for buffering the shocks, and a method of applying the same.Heretofore, a previously formed shock absorbing material is bonded by way of an adhesive or the like to an object to be buffered. However, there has been a disadvantage that no desired bonding strength can be obtained or the adhesive is degraded. It is intended in this invention to render the shock absorbing material fusible under heating, by which the shock absorbing material is fused due to the melting of the shock absorbing material itself with an object to be buffered using no adhesive thereby increasing the bonding area and improving the bonding strength as compared with the conventional case.
