PURPOSE: A spindle motor is provided to increase adhesive force between a cramp yoke and a cramp magnet by physically combining them. CONSTITUTION: A bearing supports a rotary shaft(111) to be rotatable. A turn-table(112) has a disk support part(114). A clamp yoke(117) is assembled on the top of the turn-table. The clamp magnet(118) is fixed to the top surface of the clamp yoke. A transform unit(119) change the slope in upper part of the turn table to prevent the separation of the clamp yoke from the clamp magnet. The cramp yoke and the cramp magnet are physically combined with each other.
