Summary:PROBLEM TO BE SOLVED: To provide a cage having improved assembling efficiency and dimensional stability and accuracy and adopting a resin with high temperature rigidity and less toughness. SOLUTION: The cage 6 comprises a small diameter flange portion 11, a large diameter flange portion 12, and a columnar portion 13. Roller holding portions 15 (elastically deformable node portions) are provided on both sides of the columnar portion 13. The roller holding portions 15 are shaped to be protruded from the outer diameter side of the columnar portion 13 in the circumferential direction. When a roller 5 is inserted into the cage 6, an inner ring 2 is put inside the cage 6 and the roller 5 is passed from the outside of the roller holding portion 15 (the elastically deformable node portion) and incorporated therein. After the roller 5 is passed through the roller holding portion 15, a gap is formed between a pocket 14 and the roller 5 and so no other portions than the pocket 14 being incorporated are loaded.
