To provide a vibration control structure having small bending deformation and shear deformation with respect to an axial direction while exhibiting a vibration control effect with respect to the axial direction.SOLUTION: A suspending member 50 is composed of a vibration control member 100, and an upper suspension member 52 and a lower suspension member 53 which are joined to both sides of the vibration control member 100 in an axial direction and coaxially arranged. The axial rigidity of the vibration control member 100 is smaller than the axial rigidity of the upper suspension member 52 and the lower suspension member 53, and the bending rigidity and shear rigidity of the vibration control member 100 are equal to or larger than those of the upper suspension member 52 and the lower suspension member 53.SELECTED DRAWING: Figure 2 【課題】軸方向に対する防振効果を発揮しつつ軸方向に対する曲げ変形及びせん断変形が小さい防振構造。【解決手段】吊部材５０は、防振部材１００と、防振部材１００の軸方向の両側に接合され同軸上に配置された上側吊材５２及び下側吊材５３と、で構成されている。防振部材１００の軸方向の剛性は上側吊材５２及び下側吊材５３の軸方向の剛性よりも小さく、防振部材１００の曲げ剛性及びせん断剛性は上側吊材５２及び下側吊材５３の曲げ剛性及びせん断剛性と同等以上である。【選択図】図２
