PROBLEM TO BE SOLVED: To improve the durability of a pin by firmly connecting a ring and the pin in a pin-type cage. SOLUTION: In this pin-type cage formed by extending the pins 30 at several parts in the circumferential direction of a pair of rings 10, 20, a minimum diameter part 14 is provided in each of through-holes 11 provided in several parts in the circumferential direction of the first ring 10, and the minimum diameter part 14 is clamped from the axial direction by one end of the pin 30 and a nut 40 screwed therein, to connect the pin 30 to the first ring 10. The minimum diameter part 14 of the through hole 11 is provided with a tapered face 22, and one end of the pin 30 is provided with a tapered shank 33 corresponding to the tapered face 22. The tapered face 22 and the tapered shank 33 are pressure-fixed at the face. The connecting strength of the pin 30 to the first ring 10 is thereby improved, and when impact load or the like is applied, the impact load can be received by the whole surface of the tapered shank 33 of the pin 30.
