FLUID BEARING DEVICE

摘要

Intended is to improve the bearing rigidity of a fluid bearing device and to lower the cost of the same. An oil film is formed in the radial bearing clearances of first and second radial bearings (R1, R2), thereby to support a shaft member (2) rotatably. A bearing sleeve (8) and the shaft member (2) are housed in a housing (7), and this housing (7) has its internal space filled with a lubricant and its opening sealed by a seal member (9). This seal member (9) forms a first seal space (S1) with its inner circumference (9a2). The housing (7) and the seal member (9) are formed by injection-molding of a resin.
