<P>PROBLEM TO BE SOLVED: To suppress detachment of a mass member from a mounting member by attaching a coming-off prevention member to the mounting member without having an influence on a resonance frequency. <P>SOLUTION: This vibration isolation device includes: a bracket 16 attached to a target to be subjected to vibration isolation; an elastic member 14 fixed to the bracket 16; the mass member 12 fixed to the elastic member 14; a through-hole 30 passed through the mass member 12 and elastic member 14; the coming-off prevention member 18 pressure-fitted to the bracket 16 in a non-contact manner with the through-hole 30; and a diameter enlarged part 18A on the side of the mass member, formed such that one end of the coming-off prevention member 18 on the side of the mass member 12 is increased in diameter larger than the through-hole 30. <P>COPYRIGHT: (C)2013,JPO&INPIT |
