るスピンドル機構。A disk-shaped medium having a through hole in the center, a cylindrical hub having a plurality of protruding first ribs provided at predetermined intervals on the outer circumferential surface, and a magnet formed on the inner circumferential surface of the hub. A rotor having a cylindrical outer peripheral surface fixed thereto, and a stator having an electromagnetic coil provided corresponding to the rotor,
By inserting the hub into the through hole, the through hole is fitted with the hub via the first rib, and in the spindle mechanism in which the medium is rotated by the rotational drive of the rotor, the hub is inserted into the through hole. The inner circumferential surface and the outer circumferential surface of the rotor are formed to have a predetermined gap, and in the gap corresponding to approximately the middle of the predetermined spacing between the first ribs, there is a first rib to which the hub and the rotor are fixed. A spindle mechanism characterized by having two ribs.
