A reel which is driven by a motor is disposed in a casing. First and second restraining mechanisms for restraining movement of a cable are located at first and second openings formed in the casing for insertion of the cable. The cable extends between said first and second openings and is wound around the reel. One end of the cable is secured by the first restraining mechanism, and the motor is activated to rotate the reel, thereby winding the cable around the reel. When a pressure sensor located on the surface of the reel detects that the pressure between the cable and the reel reaches a given value, the motor is stopped. The other end of the cable is secured by the second restraining mechanism.
