動装置のロータ取付構造。 Information is recorded by inserting a spindle shaft into the center hole of a rotor equipped with a rotor magnet, integrating the two, and rotating the rotor and spindle shaft by energizing an excitation coil placed opposite the rotor magnet. In a disk drive device that rotationally drives a disk, a groove extending in a direction perpendicular to the axial direction is carved in the spindle shaft, and a long hole is formed at a position corresponding to the groove in the inner circumference of the rotor. A rotor mounting structure for a disk drive device, characterized in that the rotor is fitted into the groove by plastically deforming the space between the center hole and the elongated hole.
