Claim Text:
1. A split cage comprising a plurality of cage segments, each of the cage segments having a pair of rim portions that face each other at a prescribed distance in an axial direction of the split cage, and a pair of cage bar portions disposed between the rim portions to connect the rim portions to each other, the cage bar portions and the rim portions defining a single pocket that accommodates a single roller, wherein: the cage segments are arranged in a circular pattern along a circumferential direction of the split cage, in an annular space between an inner ring and an outer ring; a circumferential clearance is provided between adjacent cage segments, and radial clearances are formed between each of the cage segments and the inner ring and the outer ring to allow a rotation of each of the cage segments, the rotation of each of the cage segments being guided by the roller; each of the cage segments has projections formed so as to project toward at least one of a radially outside and a radially inside, the projections being formed at both the rim portions and the cage bar portions, or at the rim portions or the cage bar portions; and a projecting length of each of the projections is set to such a length that the projections are brought into contact with an outer peripheral side portion of the inner ring or an inner peripheral side portion of the outer ring, toward which the projections project, when the cage segment rotates by predetermined degrees.
