To provide a DC motor in which the rattling and the axial deviation of a rotor are restrained without increasing the axial dimension of the motor. This DC motor comprises a stator (2) on which coils (4) are provided, a rotor (8) so disposed as to be opposed to the inner periphery of the stator (2) and having magnetic poles, a current-carrying part provided at one end of the rotor (8) and transferring the current fed from a power supply to the coils (4) of the stator (2), a sleeve bearing (6) holding the rotor (8), and a ball bearing (7) holding the rotor (8) and having a load-carrying capacity larger than that of the sleeve bearing (6). The outer ring of the ball bearing (7) is positioned by the stator (2), and the inner ring of the ball bearing (7) is positioned by the rotor (8).
A direct-current motor comprising:
