<P>PROBLEM TO BE SOLVED: To provide a dynamic bearing device capable of properly supporting a shaft member and a bearing member for a long period even when a sliding layer formed on a dynamical pressure face is stripped to some degree. <P>SOLUTION: A resin lubricating film in which a solid lubricating material composed of a number of granular pieces is dispersed, is applied as an abrasion-proof sliding layer 26 formed on at least one side of the dynamical pressure face at a shaft member 21 side and a dynamical pressure face at a bearing member 13 side, and a maximum particle size of the granular pieces composing the solid lubricating material included in the sliding layer is determined to be less than a minimum clearance of a bearing space of the dynamic bearing part. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
