An outer lubricating liquid inflow passage that provides communication between an outside of a liquid-lubricated bearing and a rolling element arrangement chamber is formed between an outer ring and a cage, on the lubricating liquid inflow side. The outer lubricating liquid inflow passage has an annular axially extending outer passage portion that extends in the axial direction, and an annular radially extending outer passage portion. The radially extending outer passage portion communicates with a rolling element-side axial end portion of the axially extending outer passage portion. The radially extending outer passage portion extends from the axially extending outer passage portion to the rolling element arrangement chamber inward in the radial direction of the outer ring. A labyrinth is formed by the axially extending outer passage portion and the radially extending outer passage portion. |
