To provide a granular material damper having high damping force.SOLUTION: A granular material damper A includes a case 18, an input member 34, a resistor 24, displacement force application means 30, a rotator 25, and a plurality of granular materials 36. The input member 34 is relatively displaced only in one of a linear motion direction and a rotation direction with respect to the case 18. The resistor 24 is displaced integrally with the input member 34 in the same direction as the relative displacement of the input member 34, and is allowed for relative displacement to the input member 34 in a direction different from the relative displacement of the input member 34. The displacement force application menas 30 applies, to the resistor 24, displacement force in a direction different from the displacement direction of the input member 34. The rotator 25 is formed in the resistor 24 and is stored in the case 18. The granular materials 36 apply resistance for suppressing displacement to the rotator 25 displaced in the linear motion direction and the rotation direction in the case 18.SELECTED DRAWING: Figure 2 【課題】減衰力の高い粒状体ダンパを提供する。【解決手段】粒状体ダンパＡは、ケース１８、入力部材３４、抵抗体２４、変位力付加手段３０、回転子２５及び複数の粒状体３６を備える。入力部材３４は、ケース１８に対して直動方向と回転方向のうちいずれか一方向のみに相対変位する。抵抗体２４は、入力部材３４の相対変位と同じ方向に関しては入力部材３４と一体的に変位し、入力部材３４の相対変位と異なる方向に関しては入力部材３４に対する相対変位が許容される。変位力付加手段３０は、抵抗体２４に対し、入力部材３４の変位方向とは異なる方向の変位力を付与する。回転子２５は、抵抗体２４に形成され、ケース１８内に収容されている。粒状体３６は、ケース１８内で直動方向及び回転方向に変位する回転子２５に対して変位を抑制する抗力を付与する。【選択図】図２
