Abstract
A vibration isolation device includes two attachment members inter-connected by an elastic member. One of the attachment members comprises a metal tubular member connected to the elastic member, a metal bracket in which the metal tubular member is press-fitted, and a plastic bracket supporting the metal bracket and adapted to be attached to a support body or a vibratory source. The metal bracket has an engagement portion press-fitted with the metal tubular member, and a non-engagement portion offset from the engagement portion in a radial outward direction and held out of press-fitted engagement with the metal tubular member, the non-engagement portion being connected to the plastic bracket with a second elastic member disposed therebetween.
Claims15
A vibration isolation device comprising:
- a first attachment member for attachment to a vibratory source;
- a second attachment member for attachment to a support body on which the vibratory source is to be mounted via the vibration isolation device;
- and
- an elastic member interconnecting the first attachment member and the second attachment member,
- wherein one of the first attachment member and the second attachment member comprises a metal tubular member connected to the elastic member, a metal bracket in which the metal tubular member is press-fitted, and a plastic bracket supporting the metal bracket and adapted to be attached to the vibratory source or the support body,
- wherein the metal bracket has an engagement portion press-fitted with the metal tubular member, and a non-engagement portion offset from the engagement portion in a radial outward direction and held out of press-fitted engagement with the metal tubular member, the non-engagement portion being connected to the plastic bracket with a second elastic member disposed therebetween, and
- wherein the elastic member is disposed entirely within the hollow interior of the metal tubular member.
