Abstract
PURPOSE: To prevent a leak of lubricating fluid, by means of providing a magnet for magnetic stal near the fluid bearing oil film portion.
CONSTITUTION: The portion of a fluid bearing 20 comprises a thrust bearing top part 44, its bottom part 45, a radial bearing top oil film part 46, bottom oil film part 47, thrust bearing top oil film part 48, bottom oil film part 49, and a magnetic lubricating fluid 83 is sealed by the bearing oil film parts 46, 47, 48, 49, and seized near both poles of a permanent magnet 40. In this way, between a fixed axis 79 and a rotary sleeve 74, that turns around the former, is constructed the fluid bearing 20 by the magnetic fluid 83, with the permanent magnet 40, provided in the interior of the fluid bearing 20, becoming a magnetic seal method, thus a leak of the lubricating fluid 83 is prevented.
