Abstract

PURPOSE:To form a wear resistant surface and to prevent production of abrasion powder, by a method wherein at least either of the surfaces, position facing each other, of a shaft and a dynamic pressure bearing is covered with the one or both of organopolysiloxane having a functional group and a fluorine- contained polymer. CONSTITUTION:Herringbone grooves 5 are formed in the portion, positioned facing a dynamic pressure bearing, of a shaft 2, and a film 4 is formed on the surfaces of the bore part, positioned facing the grooves, of a housing and a thrust bearing 3. The film 4 is formed by the one or both of a siloxane homopolymer, e.g. dimethylsiloxane, and a fluorine-contained polymer, e.g. organopolysiloxane, having a functional group introduced in two or more kinds of copolymers, or a polyfluoroalkyl polymer. This constitution improves wear resistance of a surface, suppresses production of abrasion powder to a value as low as possible, and enables shortening of time in which it is brought into a steady rotation state from starting.
