    摘要： Even when used at a high rotation speed, outside parts in relation to the radial direction of a cage 3, of the circumferential parts of a pocket 7 are kept from being worn away by outside end surfaces 21 of rollers 2. Moreover the rollers 2 are kept from sliding on the inside the pockets 7, to thereby stabilize the performance of rotation support parts.The outside end surface 21 of the roller 2 is made a ball convex surface, so that the center part of the outside end surface 21 can be freely in contact with the inner peripheral surface of a second outside cylindrical portion 14. In a condition with the rollers 2 displaced radially outward of the cage 3 due to centrifugal force, a PV value of a rubbing part between the outside end surface 21 and the opposite surface is kept low, and the wear of this rubbing part is suppressed.

    摘要： The rocker arm 1 has a fitting surface 6 on the opposite sides of which guide surfaces 21 are formed, such that the guide surfaces 21 are inclined to be closer to each other toward their tip ends. Even when the valve stem 20 is displaced in the widthwise direction of the fitting surface 6, the outer peripheral surface of the base end portion of the valve stem 20 comes into contact with only the tip end of one of the guide surfaces 21. Consequently, lubrication is improved and friction moment is decreased in the contact area, so that friction resistance is suppressed between the guide surfaces 21 and the outer peripheral surface of the base end of the valve stem 20 to easily obtain high performance of the engine.

    摘要： A sheet-metal rocker arm formed by the steps of punch-pressing a sheet of metal member to form a blank having a predetermined shape and a through-hole, of subjecting the blank to a bending process based on pressing to form a pair of substantially parallel side wall sections and a connection section for connecting the widthwise edges of the both side wall sections and to form at least one pair of circular holes in the both side wall sections at locations in alignment, of deforming the middle of the connection section in the thickness direction to form an engagement portion on one side of the connection section such that the engagement portion is recessed from the other portion of the connection section, and of forming on the other side of the connection section a bulge section, trapezoidal in cross section, which protrudes in an embanked-shape as the engagement portion is formed, whereby the widthwise edges of the middle of the bulge section corresponding to the top edge of the trapezoidal shape exist on the widthwise inside of the both widthwise edges of the engagement portion.

    摘要： A roller bearing for rotatably supporting a rotating shaft of an internal combustion engine between a main body and a cap of the internal combustion engine. The roller bearing including: a plurality of rollers; a retainer which is cirumferentially splittable and supports the plurality of rollers; and an outer race which is cirumferentially splittable and forms a raceway surface for the plurality of rollers. The retainer is split into a plurality of retaining members. The outer race is split into a plurality of race plates. At least one of the race plates is provided with one of a projection and a cavity to be engaged with one of the main body and the cap to restrict a relative movement between the one of the race plates and the one of the cylinder head and the cap.

    摘要： An outer ring 6a for a shell-type radial needle bearing having a cylindrical shape with a bottom is achieved for which fatigue life of the bottom plate section 9a and the continuous section between the bottom plate section 9a and the cylindrical section 8a is improved, as well as the anti-corrosion characteristic of the outer ring 6a is improved and the outer ring 6a can be prevented from coming out of the bearing without an increase in cost. After obtaining an intermediate raw material 35 having a cylindrical section and a bottom plate section from a metal raw material, shot peening is performed on the intermediate material 35 to create residual compressive stress in the surface and surface layer section on the outer surface side of the cylindrical section 8a and the bottom plate section 9a such that the residual compressive stress in the surface layer section on the outer surface side is greater than the in the surface layer section on the inner surface side, and from the surface to a depth of 0.03 mm is 700 MPa to 1600 MPa.

    摘要： The finishing process is applied to a surface of a roller 8 constituting a cam follower unit by the barrel finishing. When a position of a highest portion out of fine roughnesses existing on the surface is assumed as an outermost surface position, an occupation ratio of a sectional area of a virtual plane in a plane direction at a portion that is positioned at a depth of 2.0 μm from the outermost surface position to an area of an overall surface of a portion that contacts the other member is set to 90% or more. With this configuration, a tough oil film can be formed between the surface of the roller 8 and the other member, and also the improvement of durability of a member such as the roller 8, or the like, which contacts the other member via a rolling contact or a sliding contact, can be achieved at a low cost.
