Title:
VIBRATION ISOLATOR
Document Type and Number:
Japanese Patent JPS60116940
Kind Code:
A
Abstract:
PURPOSE:To eliminate high-frequency vibration components by combining three different vibrationproofing means in a vibration isolator used for a record player, etc. CONSTITUTION:A vibrationproofing means 4 coupled with a coil spring 3 around a reversed bowl body 2 made of a viscoelastic material is arranged between an installation table 1 and the first board 7. In addition, a vibrationproofing means 17 and a vibrationproofing means 23 are arranged in series between the first board 7 and the second board 37. The vibrationproofing means 17 is made of a viscoelastic material, and the vibrationproofing means 23 is formed with a coil spring 22 arranged in a hollow cylinder 21 made of a viscoelastic material. By adding the vibrationproofing means 17, high-frequency vibration components in particular can be eliminated, thus allowing vibrationproofing from a low-frequency area to a high-frequency area.
