【0022】その上、中心軸の心棒部に対して独立部品となるゴム弾性体として、硬度や材料等の選択によりゴム特性の異なる多種のものを準備し、そのゴム特性の異なる多種のゴム弾性体の任意の一つを選択して中心軸の心棒部に組付け一体化して用いることにより、心棒部は共通仕様にしたままで、広範囲のばね特性、つまり、防振特性を持つ複数種類の防振ゴムを容易、安価に得ることができるという効果を奏する。 [0022] Moreover, as a rubber elastic body as a separate component with respect to the mandrel portion of the central shaft, by selection of such hardness and materials prepared having different variety of rubber properties, the rubber elasticity of different variety of the rubber properties by using integrated assembly mandrel of the central axis by selecting any one of the body, while the mandrel portion has a common specification, a wide range of spring characteristics, i.e., a plurality of types having vibration damping characteristics facilitate rubber cushion, an effect that can be obtained at low cost.

【0023】特に、ゴム弾性体を周方向で複数に分割してそれらを中心軸の心棒部に対して分離組付自在に構成することにより、各分割ゴム弾性体として特性の異なるものの組み合わせ使用が可能となり、車両にブレーキがかけせれた際に特定の分割ゴム弾性体に強く力が作用する場合や近くに熱源があって、局所が熱影響を受けやすい場合などの種々の使用環境に対応してゴム弾性体全体を適切に設計して耐久性の向上を図ることもできる。 [0023] In particular, by freely configured with detachable assembly with respect to the mandrel portion of the center axis thereof is divided into a plurality of rubber elastic body in the circumferential direction, the combined use of different characteristics as the respective divided elastic body possible and will, if there is a heat source in or near the case of acts strongly force on a specific partition rubber elastic body when the brake is not applied to the vehicle, topical corresponds to various use environments, such as when subject to thermal influence it is also possible to improve the durability by appropriate design of the rubber elastic body as a whole Te.
