摘要： A chain guide includes a guide base (21) disposed to face one side of a timing chain (5) that transmits torque, the chain guide having an opposed pair of side plates (22) each formed with a plurality of shaft engaging portions (25) arranged along a circular arc. Roller shafts (31) have their ends supported by the respective shaft engaging portions (25). Rollers (41) for guiding the chain are rotatably supported by the respective roller shafts (31). Noncylidrical surface engaging portions are formed on the ends of the roller shafts (31) and on closed ends of the shaft engaging portions (50) to rotationally fix the roller shafts (31), thereby preventing the roller shafts (31) from rotating under drag torque applied from the rollers (41).

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.

摘要： A steel retainer (3), which retains needle rollers (2), is formed from a steel plate containing 0.15 to 1.10% by mass of carbon. After being formed, the steel plate is subjected to induction heat treatment which includes induction hardening and induction tempering. Such heat treatment can be carried out efficiently in a short period of time, using compact treatment facilities, even in small-lot production. The retainer (3) thus formed is sufficiently resistant to wear and surface damage, and is high in fatigue strength and fracture strength as a whole.
