To control rigidity of a damper mount by utilizing elastic property in a shearing direction of a variable elastic member composed of a magnetic elastomer material.SOLUTION: A damper mount includes: an annular inner member 21 fixed to a rod 17 of a damper; an annular outer member 22 fixed to a vehicle body component 9; a variable elastic member 24 composed of magnetic elastomer; and a coil 25 applying magnetic field to the variable elastic member. The variable elastic member is disposed in a state of being radially held between the inner member and the outer member. In particular, the inner member has a cylindrical portion 35 to which a damper-side bolt is inserted, and a pair of flange portions 36 disposed at both ends in an axial direction of the cylindrical portion, the variable elastic member is disposed between the flange portion and the outer member, the coil is disposed at an outer peripheral side of the cylindrical portion, and the inner member and the outer member are made of a magnetic material.SELECTED DRAWING: Figure 2
【課題】磁性エラストマ材料からなる可変弾性部材のせん断方向の弾性特性を利用してダンパーマウントの剛性を制御できるようにする。【解決手段】ダンパーのロッド17に固定される環状のインナー部材21と、車体構成部材9に固定される環状のアウター部材22と、磁性エラストマからなる可変弾性部材24と、この可変弾性部材に磁界を印加するコイル25とを備え、可変弾性部材は、インナー部材とアウター部材との間に径方向に挟み込まれた状態で設けられている。特に、インナー部材は、ダンパー側のボルトが挿通される筒状部35と、この筒状部の軸方向の両端に設けられた1対のフランジ部36とを有し、可変弾性部材は、フランジ部とアウター部材との間に設けられ、コイルは、筒状部の外周側に設けられ、インナー部材およびアウター部材は、磁性体材料で形成されている。【選択図】図2
