a cable, a portion of which is connected to and adapted to pull the open-and-close body;
a drum, having another portion of the cable wound thereon;
a pulley, provided between the open-and-close body and the drum, changing a direction of the cable, and being movable between a first position where the pulley is engaged with the cable and the cable is slack and a second position where the pulley engages the cable and tensions the cable;
a fix member, capable of fixing the pulley in the first position;
an elastic member, urging the pulley towards the second position and tensing the cable; and
a limiting member, provided between the drum and the fix member, and allowing or limiting rotation of the drum, wherein when the fix member fixes the pulley in the first position, the limiting member limits the rotation of the drum, and when the fix member is moved to release the elastic member which moves the pulley to the second position, the limiting member moves to allow the rotation of the drum.
