PROBLEM TO BE SOLVED: To provide a rolling bearing that detects internal wear of the bearing, and a wind turbine generator including the same.SOLUTION: The bearing 60 includes an inner ring 110, an outer ring 120, a plurality of rolling elements not shown in the figures, and displacement sensors 140A, 140B. The plurality of rolling elements are interposed between the inner ring 110 and the outer ring 120. The displacement sensors 140A, 140B are fixed on the outer ring 120 which is the stationary ring and are installed, for instance, in oil hole parts provided in an inter-outer ring seat. The displacement sensor 140B is arranged at a position shifted by 90° in a direction along the circumference relative to the displacement sensor 140A. The displacement sensors 140A, 140B output signals varying according to distances from the inner ring 110. |
