A sealing device (20) for a rolling bearing device (10) includes a metal core (21) which includes a cylindrical portion (23) fitted on an outer circumferential surface (11d) of an end portion of an outer ring (11), a circular ring portion (24) extending radially inwards from the cylindrical portion (23) while being in abutment with an end face (11e) of the end portion of the outer ring (11) and an inward edge portion (26) extending further radially inwards from a radially inward end portion (25) of the circular ring portion (24) so as to protrude towards an inner circumferential side of the outer ring (11) and on which seal lips (22a,22b,22c) are mounted. A shielding portion (27) made of an elastic material is mounted at a radially outward end portion of the circular ring portion (24) in such a manner as to extend towards a flange portion (12c) so as to shield a clearance (S) defined between the flange portion (12c) and the end portion of the outer ring (11).
