    摘要: A roller bearing comprises an outer ring, an inner ring, a plurality of rollers arranged between the outer ring and the inner ring, and a plurality of retainer segments (11a) having a plurality of column parts (14a) and (14b) extending in a direction along a shaft so as to form a pocket (13a) for holding the roller, and connection parts (15a) and (15b) extending in a circumferential direction so as to connect the plurality of column parts (14a) and (14b), and continuously lined with each other in the circumferential direction between the outer ring and the inner ring. The column part (14a) is positioned at an circumferential end of the retainer segment (11a). Here, a circumferential outer side end face (21a) of the column part (14a) positioned at the end is flat, and a circumferential inner side end face (25a) of the column part (14a) positioned at said end is provided with a recess (23a) recessed in the circumferential direction so as to reduce the thickness of the column part (14a).
