Abstract
A motor device includes: a rotor case rotated along with a shaft; a chuck housing mounted on a hub of the rotor case; a chuck member mounted on the chuck housing such that the chuck member is protruded from the interior to an outer side, to fix a disc; and a concave portion formed as a recess on the rotor case to form a gap with the chuck support in contact with the chuck member to thereby prevent a frictional contact between the rotor case and the chuck member.
