摘要： The present invention provides a rolling bearing which is excellent in strength, rigidity, heat resistance, and dimensional accuracy while being able to hold rolling elements in a stable manner and reduce manufacturing cost without degrading performance as a bearing and a manufacturing method for the rolling bearing. To achieve the object, the present invention adopts a rolling bearing including a cage provided with a plurality of pockets for housing and hold the rolling elements arranged at specific intervals in a circumferential direction in a peripheral wall of a cylindrical member. The cage is formed integrally by metal powder injection molding; and the cage includes a housing space for the rolling elements and a rolling-element fall-out prevention structure is formed by applying compressive working to an outer edge of the housing space in a direction from an outer circumferential surface toward a radial center of the cage.

摘要： Surface indentation and oil film shortage on rollers is prevented and longer service life of a roller bearing is achieved, by preventing wear debris from being caught and accumulated in pockets of a holder of the roller bearing. Positions and dimensional relations of the diameters of inner and outer ring raceways, the inner and outer diameters of the holder, and inner and outer protrusions which are provided to pillar parts of the holder to prevent the rollers from coming off are defined such that the inner and outer protrusions of the pillar parts always do not come into contact with the outer circumferential surfaces of the rollers in the state where the rollers and the holder are incorporated between inner and outer members. As a result, lubricant oil is smoothly circulated in gaps formed between the outer circumferential surfaces of the rollers and the pillar parts of the holder.

摘要： An object of the invention is to provide a pump tappet capable of bearing a large load from a pump plunger even if a case, which is a constituent member of the pump tappet, has a reduced thickness in its intermediate bottom. The invention thus contributes to reduced weight of the overall pump tappet. The case for the pump tappet is formed from an intermediary workpiece 40, which is made by means of a cold forging process of pressing a central region of a round steel material from both surfaces thereby pushing a portion of the material in the central region radially outward, forcing the material to flow axially in an up-down direction, so that an intermediate bottom 40e has a continuous fiber flow.
