PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing capable of smoothly guiding the rotation of a retainer and preventing increase of a bearing torque with a surplus oil.SOLUTION: At an outer circumference of a pillar part 5b of a retainer 5, a guide piece 6, in sliding contact with a track face 3a of an outer wheel 3, is erected. While the rotation of the retainer 5 is guided, the surplus oil on the track face 3a is removed by the guide piece 6 with the rotation of the retainer 5, and the surplus oil escapes to the both ends of the outer wheel 3. Also, a through hole 7, going through from the inner circumference of the pillar 5b to a sliding part 6a of the tip of the guide piece 6 is formed. The oil on the side of the inner circumference of the pillar part 5b is passed through the through hole 7 to be supplied to the track face 3a of the outer wheel 3. |
