内側に中間弾性吸収層700を予め形成させたリング状金属環部材800と外側にポリウレタン材製表面弾性層を予め形成させたリング状金属環部材900とを接合させる構成としているため、部品点数及び接着箇所が多いため、製造コストが嵩んだ。
また、限られたスペースでは、二種類のリング状金属環部材800、900を使用するため、中間弾性吸収層700の径方向厚みを十分とることが出来なかった。
このため、中間弾性吸収層700が十分な振動吸収特性を発揮することが困難であった。
However, this type of prior art has caused the following problems.
Since the ring-shaped metal ring member 800 in which the intermediate elastic absorption layer 700 is previously formed on the inner side and the ring-shaped metal ring member 900 in which the surface elastic layer made of polyurethane material is formed on the outer side are joined, the number of parts and Since there are many adhesion parts, the manufacturing cost increased.
Further, since the two types of ring-shaped metal ring members 800 and 900 are used in a limited space, the radial thickness of the intermediate elastic absorption layer 700 cannot be sufficiently obtained.
For this reason, it is difficult for the intermediate elastic absorption layer 700 to exhibit sufficient vibration absorption characteristics.
