PROBLEM TO BE SOLVED: To provide a bearing device where a sealability of a seal member is less likely to decrease even when misalignment occurs between axial centers of a seal cover and a seal ring, the device being capable of reducing component accuracy and improving productivity.SOLUTION: A bearing device is fit onto the inner circumferential surface of a housing and includes an annular seal cover 7 having a seal slide surface whose normal direction is substantially in the axial direction, an annular first seal ring 11 screwed onto the outer circumferential surface of a main shaft 50 of a wind turbine generator, a seal lip 73 configured to slide on the seal slide surface and a first seal member 16 fixed on the first seal ring 11. |
