摘要： Fine particles (6) are retained by an electroformed portion (4) in a dispersed state, and the fine particles (6) exposed from an outer peripheral surface (4a2) of the electroformed portion (4) are molten so as to form micro projections (60) integrated with a resin portion (5). The micro projections (60) enters into fine-particle traces (4c) formed in the electroformed portion (4) to exert an anchor effect, to thereby increase a fixation force between the resin portion (5) and the electroformed portion (4).

摘要： In order to improve retention strength of a lid member without increase in size and reduction in bearing property of a bearing device, a fluid dynamic bearing device (1) includes: a shaft member (2); a bearing sleeve (8) which forms a radial bearing gap between the bearing sleeve and an outer peripheral surface of the shaft member (2); a housing (4) which accommodates the bearing sleeve (8) and is opened at both ends; and a lid member (10) which closes an opening on one end side of the housing (9) and forms thrust bearing portions (T1 and T2). The housing (9) is an injection-molded product into which the bearing sleeve (8) is inserted, and the housing (9) has another end with which a seal portion (9b) forming a seal space (S) is integrally formed. The lid member (10) is fitted with the outer peripheral surface of the housing (9) by loose fitting so that the lid member (10) and the housing (9) are bonded and fixed to each other.

摘要： A resin housing 7 is injection-molded by using a forming mold 11. Moreover, a concave shaped adhesive reservoir 10 is formed by a sink mark of the resin during injection molding on its inner circumferential surface 7e simultaneously with the injection molding of the housing 7. Accordingly, the adhesive can be prevented from overflowing and the adverse influence caused by the overflowing of the excessive adhesive can be avoided. A decrease in the molding precision of the housing can be also prevented and cost reduction by dispensing with a processing step can be enabled.

摘要： The present invention has an object of improving wear resistance of a thrust bearing portion. A pressure is generated by a dynamic pressure effect of a lubricating oil in a thrust bearing gap C between a thrust bearing surface 11a including dynamic pressure generating grooves and a smooth thrust receiving surface 11b so as to rotatably support a shaft member 2 in an axial direction. The thrust receiving surface 11b is formed as a flat surface, whereas an inclined plane 17 is provided on the thrust bearing surface 11a so as to provide a reduced portion 15 having a decreasing axial width in a radially outward direction in the thrust bearing gap C.

摘要： The porous oil-impregnated bearing 1 comprises a bearing body 1a made of a porous material, and oil retained in the pores of the bearing body 1a by impregnation with lubricating oil or lubricating grease. The inner peripheral surface of the bearing body 1a is formed with a bearing surface 1b opposed to an outer peripheral surface of a shaft to be supported, with a bearing clearance defined therebetween. The bearing surface 1b has a first region m1 in which a plurality of hydrodynamic pressure generating grooves 1c inclined in one direction with respect to the axial direction are circumferentially disposed, a second region m2 which is axially spaced from said first region m1 and in which a plurality of hydrodynamic pressure generating grooves 1c inclined in the other direction with respect to the axial direction are circumferentially disposed, and an annular smooth region n disposed between the first and second regions m1 and m2.
