PROBLEM TO BE SOLVED: To provide a fixing structure for a bearing having high rigidity with respect tot external vibrations, with respect to requests for size reduction, thinning, high reliability and high sensitivity of a motor for rotating disk. SOLUTION: The bearing 8, an engaging part 4a and an engaged part 21 are accommodated inside a recess 15, which is formed at the center of a rotor frame 2; an aligning member 3 is attached to the rotor frame 2, while internally surrounding the recess 15, a bearing housing holding part 16 which accommodates and holds at least a half of the axial dimension of a cylinder-shaped part of a bearing housing 9 is integrally formed at a bracket 13; a diameter-expanded part 20 is formed at the upper end of the bearing housing holding part 16; and an angle of the diameter-expanded part 20 is set so that an ultraviolet ray irradiated for making a photocuring adhesive cure, which is filled between and among the diameter-expanded part 20, the bearing housing holding part 16 and the bearing housing 9 is not blocked by the engaged part 21, and penetrates the diameter-expanded part, without fail.
