To provide a vibration isolator capable of restricting the deformation of an elastic body when inputting large vibration without using a separated stopper member, and a fitting member used for the vibration isolator.SOLUTION: A vibration isolator 1 comprises: a burner cylinder 21; an inner cylinder 22; a cylindrical periphery fixed on the inner peripheral side of the burner cylinder 21; an inner peripheral part fixed on the outer peripheral side of the inner cylinder 22; two legs for connecting the periphery to the inner peripheral part; a rubber member 23 for connecting between the burner cylinder 21 and the inner cylinder 22; an inside attachment member 3 for attaching the inner cylinder 22 to a vibration generating part 5; and an outer attachment member 4 for attaching the burner cylinder 21 to a vibration passive part 6, in which the inside attachment member 3 is composed of an insertion part 31 inserted into the inner cylinder 22; a fitting part body having a fitting part 32 for attaching the insertion part 31 to the vibration generating part 5; and a stopper part 33 which is inserted into a space divided by the inner peripheral part and the outer peripheral part of the rubber member 23, and the leg to suppress the deformation of the rubber member 23.SELECTED DRAWING: Figure 1

    【課題】別体のストッパ部材を用いることなく、大きな振動が入力したときの弾性体の変形を抑制できる防振装置と、この防振装置に用いられる取付部材とを提供する。【解決手段】外筒21と、内筒22と、外筒21の内周側に固定される筒状の外周部と、内筒22の外周側に固定される内周部と、外周部と内周部とを連結する2つの脚部とを有し、外筒21と内筒22とを連結するゴム部材23と、内筒22を振動発生部5に取付ける内側取付部材3と、外筒21を振動受動部6に取付ける外側取付部材4とを備えた防振装置1において、内側取付部材3を、内筒22内に挿入される挿入部31と、挿入部31を振動発生部5に取付ける取付部32とを備えた取付部本体と、ゴム部材23の内周部と外周部と脚部とにより分割された空間に挿入されて、ゴム部材23の変形を抑制するストッパ部33とから構成した。【選択図】図1
