PROBLEM TO BE SOLVED: To provide a spindle motor equipped with a disk turntable capable of inexpensively obtaining a clamping force small in variation and a disk centering performance high in precision while maintaining a high reliability against environmental changes. SOLUTION: A center guide part 20, a centering pawl 21, and a disk mounting part 3 are integrally formed by a resin, a bending part 23a formed in a suction plate 23 so that the suction plate 23 is on the same plane of the top surface 20a of the center guide part 20 is pressed into a hole 24 formed in the bottom surface of the recess 22 of the center guide part 20, and the space of the pressing-in part is filled with a resin 25 more elastic than the resin for integral molding to constitute a turntable 2.
