The one-way clutch 24 is configured to transmit a drive force of the electric motor 5 to the drum 25 only when the rotary force based on the tension of the belt 2 is given to the drum 25. The loosenss-removing mechanism 71 has a small electric motor continuously driven to give the rotary force to the drum 25. COPYRIGHT: (C)2011,JPO&INPIT
