Description
第１実施形態では、弾性材料３５の内部に微小粒子状の材料であるフィラー３６が分散されている。フィラー３６は、弾性材料３５よりも圧縮率が小さい材料によって構成されている。「圧縮率」は、外力を付与する前後での体積の変化率を表す値である。圧縮率が小さいほど、外力が付与されたときに体積が低減される度合いが小さい。フィラー３６は、弾性材料３５よりも硬度が高い材料によって構成されているとしてもよい。フィラー３６は、例えば、金属や、樹脂、セラミック、ガラスなどによって構成されてもよい。フィラー３６の機能については後述する。 In the first embodiment, the filler 36, which is a fine particulate material, is dispersed inside the elastic material 35. The filler 36 is made of a material having a smaller compression ratio than the elastic material 35. The "compression rate" is a value representing the rate of change in volume before and after applying an external force. The smaller the compression ratio, the smaller the degree of volume reduction when an external force is applied . The filler 36 may be made of a material having a hardness higher than that of the elastic material 35. The filler 36 may be made of, for example, metal, resin, ceramic, glass, or the like. The function of the filler 36 will be described later.
