PURPOSE:To correctly set a work by installing a compression spring between the first and the second hands which move in slidable ways on a turning sidable board. CONSTITUTION:A compression spring 7 is installed between the edge surfaces of the first and the second hands 1 and 2, and a turning base 11 for turning which has a slidable base board 8 fixed is turned by a rotary shaft 12 which is turned by a turning driving part 13. When a work 15 is held by a holding hook 4 and transported to a work base 16, the work 15 contacts with the work board 16, and then the work advances a little, and an upward reaction force is generated between the work 15 and the work board 16, and said reaction force is transmitted to the compression spring 7 through the work 15, second hand 3, and the second slidable element 6, and the length of the compression spring 7 contracts to absorb and soften the reaction force.
