Abstract:
1. A dynamic pressure bearing apparatus comprising: a shaft rotatably inserted into a bearing sleeve attached to a frame, said rotary shaft being supported by a dynamic pressure generated by a lubrication fluid injected into said bearing sleeve without contacting said rotary shaft; a rotor which is joined with a projecting portion of said rotary shaft so as to rotate integrally with said rotary shaft; a cover plate made of a thin flat member for closing an opening of said bearing sleeve having two edges along said rotary shaft between both longitudinal edges of said rotary shaft, said opening being provided at an edge opposite to the other edge to which said rotor is connected; a product data label having desired information visibly printed thereon, said product data label adhesively attached to an edge of said frame, said frame having a plane about parallel to said bearing's outer surface plane on said cover plate; wherein the area of said frame edge on which said label is attached is arranged at the outer end of the area on said cover plate facing the rotary shaft in the radial direction such that said label does not overlap with said cover plate in the shaft direction at least in said area of said cover plate facing said rotary shaft.
