In the magnetic response type resilient means, with simple constitution, as modulus of elasticity change is made control possible easily, it improves degree of freedom of the software material design. Making the magnetic particle the elastic material disperse, the magnetic elastic body which becomes (2) and in the magnetic elastic body (2) the magnetic elastic body (2) impressing the magnetic field from outside, the magnetic field occurrence section to which the magnetic elastic body (2) changes modulus of elasticity (3) it has. The magnetic elastic body (2) load from outside receives (F) in the origin of the modulus of elasticity which changes it is impressed the magnetic field where (B) according to strength by the magnetic field occurrence section (3). The magnetic elastic body (2) impressing the magnetic field (B) from outside, because the magnetic elastic body (2) it changes modulus of elasticity, the magnetic elastic body (2) and separating the magnetic field occurrence section (3), be able to design individually, the magnetic elastic body (2) and the magnetic field occurrence section (3) design efficiency improves in comparison with those of one body. Because the magnetic field occurrence section (3) is separated from the magnetic elastic body (2), without being restricted, the magnetic field occurrence section (3) control, therefore control of modulus of elasticity change becomes easy in form and constitution of the magnetic elastic body.< Selective figure >Figure 1磁気応答型弾性装置において、簡単な構成により、弾性率変化を容易に制御可能とすると共にソフトマテリアル設計の自由度を向上させる。弾性材料に磁性粒子を分散させてなる磁性弾性体(2)と、磁性弾性体(2)に磁性弾性体(2)の外部から磁場を印加して磁性弾性体(2)の弾性率を変化させる磁場発生部(3)とを備える。磁性弾性体(2)は、磁場発生部(3)によって印加される磁場(B)の強さに応じて変化した弾性率のもとで外部からの負荷(F)を受ける。磁性弾性体(2)の外部から磁場(B)を印加して磁性弾性体(2)の弾性率を変化させるので、磁性弾性体(2)と磁場発生部(3)を分離して個別に設計でき、磁性弾性体(2)と磁場発生部(3)が一体のものと比べて設計効率が向上する。磁場発生部(3)が磁性弾性体(2)から分離されているので、磁性弾性体の形状や構成に制約されずに、磁場発生部(3)の制御、従って弾性率変化の制御が容易となる。【選択図】図1
