PROBLEM TO BE SOLVED: To retain a protective cover for covering and protecting a magnetic encoder portion of a vehicular rolling bearing device.SOLUTION: The protective cover 20 includes: a first annular portion 21 which covers the magnetic encoder portion 16; a first cylindrical portion 22 which is extended from an inner diameter end 21a of the first annular portion 21 and fitted into an inner periphery 11d of an inner ring member 11; and a retention portion 23 which retains the protective cover 20 by being formed at an axial end 22a opposite to the arrangement side of the first annular portion 21 in the first cylindrical portion 22 so as to extend from the inner periphery 11d of the inner ring member 11 to the vehicle inner-side end surface 11a and opposite vehicle outer-side end surface 11c of the inner ring member 11. The retention portion 23 is bent to the radially outside beyond the first cylindrical portion 22, and is elastically deformable in the radial direction. |
