The seal 2 includes a core bar 21, and a first elastic member 22 attached to the core bar 21. The core bar 21 includes a first cylindrical portion 212 and a first flange portion 212. An outer peripheral face of the first cylindrical portion 211 is disposed in opposition to an inner peripheral face of an outer ring of the bearing device. The first elastic member 22 has a thick portion 221 and a thin portion 222 disposed on an outer peripheral face 211a of the first cylindrical portion 211. The thick portion 221 is disposed at one side farther from the bearing internal space in an axial direction of the bearing device. The thin portion 222 is extended toward an end of the opposite side of the thick portion 221 from the thick portion 221. An outer peripheral face of the thick portion 221 is projected outward from an outer peripheral face of the thin portion 222 with respect to a radial direction of the bearing device.
