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 plurality 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 pocket that accommodates a roller, and a pocket-side side face of each of the cage bar portions being a pocket-side face that is allowed to be in sliding contact with an outer peripheral face of the roller, wherein: turning of each of the cage segments is guided by the roller, the cage segments being 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; and a radial clearance between a radially inner portion of the pocket-side face of each of the cage bar portions and the outer peripheral face of the roller is set larger than an amount of change in a pitch circle radius of the cage segment when the cage segment is displaced radially outward due to thermal expansion.
