摘要： The present invention aims to achieve a reduction in cost for a fluid dynamic bearing device. The fluid dynamic bearing device supports a shaft member (2) radially in a non-contact fashion by a dynamic pressure action generated in a radial bearing gap between an outer peripheral surface of the shaft member (2) and an inner peripheral surface (7a) of a bearing member (7), and is composed of the shaft member (2), the bearing member (7), a cover member (8), and a seal member (9). The shaft member (2) is inserted into an inner periphery of the bearing member (7), and an opening at a lower end thereof is sealed by the cover member (8). The seal member (9) is attached to an opening at an upper end of the bearing member (7), forming a seal space (S) between itself and the outer peripheral surface of the shaft member (2). Dynamic pressure grooves (G) of radial bearing portions (R1 and R2) are formed in an inner peripheral surface (7a) of the bearing member (7) by molding.

摘要： Disclosed is a dynamic bearing device which allows production of a smaller housing at low cost and which suppresses ion elution from the resin portion to thereby maintain cleanliness in the dynamic bearing device and exert a desired bearing performance. A dynamic bearing device 1 is equipped with a bearing sleeve 8 fixed to the inner periphery of the housing 7, and a rotary member rotatable relative to the bearing sleeve 8 and the housing 7, in which the rotary member is supported in the radial direction and the thrust direction in a non-contact manner by a dynamic pressure action of a lubricant fluid generated in a bearing clearance. The housing 7 is formed by injection molding of a resin composition containing polyphenylene sulfide (PPS) as the base resin and PAN type carbon fibers as a filler.

摘要： A density of a bearing sleeve made of a sintered metal is set within a range of from 80% to 95% with respect to a true density, and a Young's modulus of the bearing sleeve is set to be equal to or more than 70 GPa. When the density of the bearing sleeve is increased and also the Young's modulus thereof is set to be equal to or more than 70 GPa in this manner, dimensional variation of an inner peripheral surface of the bearing sleeve can be suppressed to be equal to or less than 0.5 μm when a shaft member having an outer diameter of from 2 mm to 4 mm is to be supported.

摘要： It is an object of the present invention to provide a bearing member having a highly accurate dynamic pressure generating portion stably at low cost. Dynamic pressure grooves (8a1) and (8a2) are formed as the dynamic pressure generating portions on an inner circumferential surface of the electroforming portion (10) by an electroforming process, and injection molding is performed by using a resin while inserting the electroforming portion (10), thereby forming a bearing member (8). A shaft member (2) is inserted into an inner circumference of the bearing member.
