To provide a bush advantageous when changing a spring characteristic while saving costs with a simple constitution.SOLUTION: A bush 10A comprises a metallic inner cylinder 12, a metallic outer cylinder 14, and an elastic member 16 provided between the cylinders. A shape memory alloy 18 is provided on the elastic member 16. The elastic member 16 is provided between the inner cylinder 12 and the outer cylinder 14, and formed of various prior elastic materials such as rubber. The shape memory alloy 18 performs a shape recovery action by self-heating (Joule heat) due to energization, and changes a spring characteristic of the bush 10A.SELECTED DRAWING: Figure 1

    【課題】簡素な構成によりコストを抑制しつつばね特性を変化させる上で有利なブッシュを提供する。【解決手段】ブッシュ10Aは、金属製の内筒12と外筒14とそれらの間に設けられた弾性部材16を備え、弾性部材16には形状記憶合金18が設けられている。弾性部材16は、内筒12と外筒14との間に設けられ、ゴムなどの従来公知の様々な弾性材料で形成されている。形状記憶合金18は、通電による自己発熱(ジュール熱)によって形状回復動作を行ないブッシュ10Aのばね特性を変化させるものである。【選択図】図1
