SOLUTION: A motor 1 for operating a gear 3 via a transmission device 2 is provided to drive a towing tool (roller chain) 5 via a gear 4 by rotation of the motor 1. The tool 5 is hinge-coupled to a side portion 10 of a central frame structure in which a separate band, stopper and brake unit movable via guide means 17, 18 along a horizontal guide 19 by front and rear portion towing tools 8, 9 are arranged. Front and rear portion limit switch surfaces 12, 13 are formed in heights of the means 17, 18 on the portion 10. At the time of horizontally moving the structure, it is made useful to position the structure in cooperation with limit switches 14, 15 disposed at both sides of a horizontal guide 19. |
