Zusammenfassung:	A bearing (40) includes an inner ring (45), a plurality of rollers (43), and a first cage (41) and a second cage (42). The first cage includes a first rear ring (413), a front ring (412), and a plurality of first columnar parts (411). The second cage includes a second rear ring (421) and a second columnar part (422). The second cage is made of an oleoresin material. The second columnar part includes a central part (422a) which overlaps a virtual cylindrical surface (E) passing through a central line of the plurality of rollers, an outer part (422b) positioned on a radially outward side of the central part, and an inner part (422c) positioned on a radially inward side of the central part. The outer part includes a widened part (422f) having a circumferential width larger than that of the central part.
