ABSTRACT:
A disk driving spindle motor wherein a hub portion having a flange portion on which a disk is to be clamped is supported for rotation relative to a housing body and a rotor frame is attached to the flange portion, the hub portion being driven for rotation by magnetic repulsive action produced between the housing body and the rotor frame. A clearance extending from the outer to the inner periphery of the flange portion is formed between the abutment surfaces of the flange portion and the rotor frame. This structure results in decreased warping of a disk attached to a disk support surface.
