PROBLEM TO BE SOLVED: To provide a vibration isolation mount device which can stably fix an elastic body to a bracket while maintaining vibration isolation performance, in the vibration isolation mount device in which the elastic body is held at an internal peripheral part of the bracket in a non-contact manner.SOLUTION: A vibration isolation mount device comprises an inner cylinder 2, a bracket 3 which surrounds the inner cylinder 2, and vibration isolation rubber 4 interposed between the inner cylinder 2 and the bracket 3. The vibration isolation rubber 4 has a base part 5 penetrated by the inner cylinder 2, and leg parts 6, 7 which protrude outwardly from the base part 5. The bracket 3 has an annular part 8 which surrounds an external peripheral part of the base part 5, and holding parts 9, 10 which hold the leg parts 6, 7. Penetration holes 21, 22 are formed at the holding parts 9, 10 of the bracket 3, recesses 23, 24 communicating with the penetration holes 21, 22 are formed at the leg parts 6, 7 of the vibration isolation rubber 4, and there are arranged shaft-shaped members 25, 26 which penetrate the penetration holes 21, 22, and are inserted into the recesses 23, 24.
【課題】弾性体が非接着でブラケットの内周部に保持される防振マウント装置において、防振性能を維持しつつ、弾性体をブラケットに安定して固定することができる防振マウント装置を提供すること。【解決手段】内筒2と、この内筒2を取り囲むブラケット3と、内筒2とブラケット3との間に介装される防振ゴム4とを備える。防振ゴム4は、内筒2が貫通される基部5と、基部5から外方に突出する脚部6、7とを有し、ブラケット3は、基部5の外周部を取り囲む環状部8と、脚部6、7を保持する保持部9、10とを有する。ブラケット3の保持部9、10に貫通孔21、22を形成し、防振ゴム4の脚部6、7に、貫通孔21、22と連通する凹部23、24を形成し、貫通孔21、22を貫通して凹部23、24に挿入される軸状部材25、26を備えた。【選択図】図1
