摘要： A needle bearing functioning as a rolling element comprises a uniform-diameter body part and bottom surfaces shaped in flat surfaces. A tapered reduced-diameter part and a chamfered part are interposed between the body part and the bottom surface. A gentle reduction in diameter is first made by the tapered reduced-diameter part, and then a relatively sharp reduction in diameter is made by the chamfered part. Consequently, in the needle bearings adjacent to each other, their tapered reduced-diameter parts are separated from each other.
