Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high-strength plastic cage by making simple the assembly thereof. SOLUTION: This cage, which is for guiding a plurality of bearing rollers by separation, comprises a first member 7 and a second member 10 which are made of a plastic material. The first member 7, which projects from one face of a ring part in its axial direction, has a plurality of web parts that comprise a pocket to accommodate the roller, while the second member 10 is a ring member to secure free ends of the web parts. In this case, the first member 7 and the second member 10 have an upright part 15 and a recess part 11, respectively, which are fitted integrably with each other by weld joints being welded that are at different levels apart from each other in the axial direction.
