摘要： There are provided a motor and a recording disc driving device, which may improve a coupling structure of the motor to enable a magnet provided in a rotor to thereby double as a conventional stopper. The motor may include: a sleeve into which a shaft is rotatably inserted; a sleeve holder including a body part into which the sleeve is inserted, and a flange part protruded from an upper end portion of the body part in an outer diameter direction; a rotor case fastened to an upper end portion of the shaft, and formed such that a cylindrically shaped-rotor main wall is protruded downwardly in an axial direction to receive the flange part; a magnet fastened to a distal end of the rotor main wall so that a part of the magnet is protruded downwardly of the flange part; and a stator fastened to face the magnet, and generating an electromagnetic force.
