PROBLEM TO BE SOLVED: To prevent the leakage of oil from a clearance between a bearing housing and an outer ring of a roller bearing, and to properly maintain pilot pressure when imparting the pilot pressure to the roller bearing by using liquid pressure such as oil pressure. SOLUTION: This roller bearing comprises a roller 34, an inner ring 33 having at its external periphery a raceway surface on which the roller 34 rolls, and the outer ring 32 having at its internal periphery a raceway surface on which the roller 34 rolls and which can bear a load directing toward one side in the axial direction from the roller 34. A seal member 38 having a lip 40 which protrudes outside in the radial direction and to one side in the axial direction is arranged on the external peripheral face of the outer ring 32.
