摘要： PROBLEM TO BE SOLVED: To solve a problem with the lowering of a service life by the combination of a long-life shaft with a pivotally supporting member by improving the relatively rotating shaft and the pivotally supporting shaft to prevent deposits from being accumulated between bearings and abnormal heating from occurring by slidable movement. SOLUTION: This pump comprises a roughly cylindrical body 2 forming a casing, a rotating body 3 installed in the roughly cylindrical body 2 and rotated, by a drive means on the outside of the roughly cylindrical body 2, integrally with an impeller 4 in a casing formed integrally with the roughly cylindrical body 2 and supported by the shaft 5, and annular pivotally supporting members 6 and 8 fitted to the inner peripheral part of the rotating body 3 and rotated relative to the shaft 5. The shaft 5 and the pivotally supporting members 6 and 8 form dynamic pressure grooves 6a and 8a or one-way grooves 6b and 8b generating the flow of a fluid in either of the shaft 5 and the pivotally supporting members 6 and 8 by the relative rotation thereof.

摘要： PROBLEM TO BE SOLVED: To provide a dynamic pressure bearing which can prevent a prominence of an inner part in the diameter direction of a flange part when a groove for generating dynamic pressure is produced at the flange part by plastic working such as stamping or the like. SOLUTION: The dynamic pressure bearing has an axis 1 and the flange part 2 extending outward from the axis 1 in the radial direction. Then grooves 6, 7 for generating dynamic pressure are formed by stamping on surfaces 3a, 3b of an outer diameter part 3 of the flange part 2, and an inner diameter part 5 is more recessed than the outer diameter part 3 in the axis direction. Thus, the inner diameter part 5 is less bowed in the axis direction than the outer diameter part 3 when the grooves 6, 7 are pressed.Thus, the flow of dynamic-pressure-generating fluid is smooth, and contact between the flange part 2 and bearing surfaces J1, J2 facing the flange part 2 can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a hydrodynamic bearing capable of improving an adhesion force between a cover member (thrust plate) and a bearing sleeve, and preventing the seepage of an adhesive to a sealed space in the bearing sleeve.
SOLUTION: A annular recess 21 communicated with a space S between the inner circumferential surface 13y of a circumferential step 13s and the outer circumferential surface 14y of the cover member 14 is formed in at least one of the junction surface 13x of the bearing sleeve 13 and the junction surface 14x of the cover member 14. In this constitution, the adhesive 30 can be filled even in a diametrical space (the annular recess 21) formed in the junction surfaces. This hydrodynamic bearing is thus capable of preventing the lubricating fluid enclosed in the sealed space 31 in the bearing from leaking outward. By forming a circular groove 22 as a sump part for the adhesive 30 in the junction surface 13x on the inner side of the annular recess 21 in a diametral direction, the seepage of the adhesive 30 to the sealed space in the bearing can be prevented.

摘要翻译：要解决的问题：提供能够改善盖构件（推力板）和轴承套之间的粘合力的流体动力轴承，并且防止粘合剂渗透到轴承套筒中的密封空间。解决方案：在圆周台阶13s的内圆周表面13y和盖构件14的外圆周表面14y之间与空间S连通的环形凹部21形成在轴承的接合表面13x中的至少一个中套筒13和盖构件14的接合面14x。在这种结构中，粘合剂30甚至可以在形成在接合表面中的直径空间（环形凹部21）中填充。因此，该流体动力轴承能够防止包封在轴承的密封空间31内的润滑流体向外泄漏。通过在环状凹部21的径向内侧的接合面13x中形成作为粘接剂30的贮槽部的圆形槽22，能够防止粘接剂30向轴承的密封空间的渗漏。版权所有（C）2004，JPO
