PURPOSE: To fix a track ring by heating a deformable element of a one-way characteristic form-memory alloy after loosely inserting the deformable element into a space between the track ring and an immovable surface of a member to be fixed in an annular space. CONSTITUTION: Two outer rings 3 are mounted within a housing 1, keeping an interval by an interconnecting passage 4 of a form-memory alloy. Inner rings 8 are mounted on a shaft 9, keeping an interval by an interconnecting passage 12. The interconnecting passage 12 is attached to a step surface 10 of a large diameter section of an axis and a retaining ring 11 by a remaining stress. When an entire bearing is heated over the critical A. temperature after these processes, lengths of the interconnecting passages 4, 12 to an axis direction are rapidly increased, and the outer rings 3 and the inner rings 8 are attached to a shaft 2, the step surfaces 6, 10 of the housing 1, the retaining ring 11 and a cover disc 7.
