PROBLEM TO BE SOLVED: To provide a rollers with a cage capable of preventing the dropping out of the rollers on both outer diameter side and inner diameter side and excellent in integrating property by locking the roller by both side edges of a pocket on the outer diameter side and engaging both ends of the roller with the annular groove of the cage on the inner diameter side. SOLUTION: A cage 1 performs the outer diameter side locking of a roller 2 by a column part 7 between pockets 3 and the inner diameter side locking by the engagement of both ends of the roller 2 with the annular groove 4 of the cage 1. Since the inner diameter side locking is performed by the annular groove 4 of a collar part 1b, the column 7 can be made into a simple shape without requiring the bending in V-shape. Therefore, the limitation in working in minimized, and the width of a column part 1b can be reduced as much as possible, so that the number of rollers 2 or the diameter of the roller 2 can be increased to increase the load capacity without increasing the bearing setting space.
