摘要： The housing made of a resin composition is formed by injection molding with a sintered metal bearing sleeve as an insert piece. The housing includes a cylindrical body part, a sealing portion extending from the top of the body part radially inwards, and a bottom part closing the lower end of the body part. Of these, the body part and bottom part are integrally formed, to which the sealing portion is welded.

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： A fluid dynamic bearing device capable of exercising high bearing performance is provided at low cost.A housing 7 is injection molded with a bearing sleeve 8 as an insert. Accordingly, the molding of the housing 7 and the assembly of the housing 7 and the bearing sleeve 8 can be performed in a single step. In addition to this, by simply increasing the die precisions the housing 7 and the bearing sleeve 8 can be fixed easily with high precision. Since the housing 7 is opened at both ends, it is possible to sandwich the bearing sleeve 8, and accordingly, the bearing sleeve 8 can be accurately positioned inside the dies with reliability.
