The present invention provides a single-split cage capable of continuously holding a plurality of rolling elements stably for a long time by eliminating the difference in the strength between split regions, by maintaining the strength of the entire cage uniform in the circumferential direction and by maintaining the dimensional accuracy between the split regions constant at the time of molding and also capable of improving load capacity and achieving low cost for assembly. A split section 10 for splitting at one portion in the circumferential direction is formed at regions (split regions 10a and 10b) extending between pockets 2p adjacent to each other in the circumferential direction, engagement sections being engageable with each other are provided at the circumferential central position between the pockets and on a one-side split face Sa and the other-side split face Sb formed by splitting the regions, and in a state in which both the engagement sections are engaged with each other, predetermined clearances are formed between the one-side split face and the other-side split face and between the engagement sections. |
