PROBLEM TO BE SOLVED: To provide a solid-shaped needle bearing facilitating processing of an outer ring at low cost, and having excellent handleability.SOLUTION: In a solid-shaped needle bearing 10, at both end parts in an axial direction of an outer ring 13, an annular relief part 14 having a larger diameter than an outer ring raceway surface 13a is formed. Also, the outer peripheral surface of a pair of rim parts 21 includes an engagement projection part 24 that elastically deforms and contracts in inserting the outer ring raceway surface 12, elastically returns after insertion to engage with the relief part 14, and positions an axial position of a holder 20 to the outer ring 13.SELECTED DRAWING: Figure 1 |
