Abstract

PURPOSE:To produce a high effect of insulation over a wide range of vibration frequency, by causing one of two vibration insulating members having magnetism to repulse each other, to float at a standstill in a magnetic fluid and by utilizing the low transmittivity of vibration in the fluid. CONSTITUTION:Two vibration insulating members 5, 6 having magnetism are provided so that their same poles are opposed to each other. The members 5, 6 are kept floating at a standstill in a magnetic fluid 8 which is a colloidal solution containing fine magnetic powder stably dispersed in liquid. As a result, the vibration insulating member 5 is entirely kept out of contact with other members in the equipment when a vibration source W is put on a carrier 1. A very high effect of insulation of vibration is thus produced.
