摘要： A shell type needle roller bearing for a universal joint is provided which can eliminate radial gaps. A plurality of needle rollers are mounted in an outer ring which has a cylindrical portion adapted to be fitted in a bearing ring formed in a bifurcated piece of a yoke and having a bottom at one end. The cylindrical portion is formed by three arcuate wall portions having equal circumferential lengths to each other. When a trunnion of a universal joint is inserted into the shell type needle roller bearing, the arcuate wall portions are resiliently deformed radially outwardly through the needle rollers, so that the needle rollers are pressed against the outer circumferential surface of the trunnion by the recovering resilience. This prevents formation of radial gaps.

The inner roller retainer (13) has pillars (5) each left between the neighboring pockets to retain the circular row of the rollers from radially inwardly and having an outer diameter smaller than the diameter of the pitch circle PCD of the circular row of the rollers. The outer roller retainer (23) has pillars (5) each left between the neighboring pockets to retain the circular row of the rollers from radially outwardly and having an inner diameter greater than the pitch circle diameter PCD. One of the outer and inner roller retainers is made of a metallic material while the other thereof is made of a resinous material.

摘要： A steel connecting rod that is used mainly in a small-size internal combustion engine includes generally elongated first and second connecting rod forming plates (2) prepared from a steel plate by the use of a press work and having bearing holes (4, 5) defined in opposite ends of each of the first and second connecting rod forming plates (2) in the form of burrings (8, 9). The first and second connecting rod forming plates (2) are joined in face-to-face relation with each other. Bearings (10) are press-fitted into the bearing holes (4, 5) so as to straddle between the burrings (8, 9) at each end of the first and second connecting rod forming plates (2). The height (a) of a corner (11) formed at a radially inner base end of each burring (8, 9) is chosen to be smaller than the plate thickness (t) of each of the first and second connecting rod forming plates (2). Each of the first and second connecting rod forming plates (2) is made from a steel plate that is not heat-treated.
