Abstract

PURPOSE: To prevent the deterioration in the damper effect by means of an oil film formed in a clearance between a mobile disc and a fixed disc arranged horizontal.
CONSTITUTION: The first magnet S is imbedded on the inner bottom of a casing 1. Facing this magnet S, arranged is a mobile disc 14 having a small-diameter projection 13 having the second magnet N imbedded. When a pivot shaft 19 rotates, a lubricant flows through a concave section between a spherical body 18 and a bearing seat 17 while flowing into a clearnace between the mobile disc 14 and a fixed disc 20 to form an oil film. Consequently, the magnets N and S applies a centripetal force to ensure smooth rotation of the pivot shaft 19. As the mobile disc 14 and the fixed disc 20 are both flat and arranged parallel, an oil film of the lubricant is present in a fine clearance between both discs thereby eliminating the generation of bubbles.
