Claim:
1. A single-split cage comprising: a pair of rim sections and a plurality of pillar sections, wherein: the pair of rim sections has a discontinuous incomplete ring shape, respectively having deficit sections, each at one portion, and the deficit sections of the rim sections are disposed coaxially in an axial direction so as to be opposed to each other with a predetermined clearance provided therebetween in a state in which the deficit sections have a same phase in a circumferential direction; the plurality of pillar sections are used to connect the pair of rim sections and to separate a region between the rim sections in the circumferential direction of the rim sections, thereby forming pockets for allowing rollers serving as rolling elements to be inserted and held rotatably; the pair of rim sections has thin sections being thin in a radial direction, the diameter of outer circumferential sections of which is made smaller than that of an outer circumferential section of the pillar sections, and also has thick sections being thick in the radial direction, a diameter of which is made larger than that of the thin sections, the thin sections having a smaller dimension in the radial direction than the thick sections; the thin sections are disposed at portions positioned on an opposite side of the deficit sections with respect to the center of the outer circumferential sections of the pair of rim sections; inner circumferential sections of the pair of rim sections are made larger in diameter than inner circumferential sections of the pillar sections, whereby the thin sections are made thinner than the thick sections on both outer diameter sides and inner diameter sides in the radial direction; and portions made thinner than the thick sections on the outer diameter sides in the radial direction and the portions made thinner than the thick sections on inner circumferential sides in the-radial direction are disposed in the same phase in the circumferential direction.
