Title:
MAGNETIC FLUID SEAL
Document Type and Number:
Japanese Patent JPS5828059
Kind Code:
A
Abstract:
PURPOSE:To facilitate machining and assembling of a retaining member for a supply magnetic fluid by pressing and fixing a magnetic fluid containing member disposed along the inner peripheral wall of a magnet member by elastic restoring force of a beltlike elastic member mounted on the inner periphery of the magnetic fluid containing member. CONSTITUTION:A magnetic fluid containing member 13 conprising a wavy beltlike plate formed of plastics, a metallic material or the like is disposed in a space between yokes 12a, 12b along the inner peripheral wall of a magnet member 11. A beltlike elastic member 14 comprising a plate formed of plastics, a metal or the like which has enough elasticity is elastically deformed in a circle to be put along the inner periphery of the magnetic fluid containing member 13. Thus, the member 13 is pressed against the inner peripheral wall of the magnet member 11 by restoring force of the beltlike elastic member 14 to be fixed at that position.
