An electrical cable retractor is provided with a reel on which a length of electrical cable is attached and wound in such a manner as to permit the inner end of the cable to remain fixed to a stationary drum on which the reel rotates while the outer portion of the length of cable is wound on or unwound from the reel. The electrical cable stored on the reel of the retractor is thus permitted to be connected to a power source without the need of brushes and slip rings. A spring motor is provided on the retractor for reversely rotating the reel so that the portion of the length of cable that is withdrawn from the retractor is maintained taut at all times.
