PROBLEM TO BE SOLVED: To reliably hold a cloth sheet by moving left and right needle bodies capable of sticking into the cloth sheet up to an opening position opened by dropping the cloth sheet from a holding position to hold them by sticking them into the cloth sheet. SOLUTION: Left and right swinging bodies 6 and needle bodies 3 are put in a vertical condition and in an opening position by a moving driving machine 8. Next, a cloth sheet holder 1 is lowered to the uppermost part of a cloth sheet B, and the left and right needle bodies 3 stick into the cloth sheet B. Next, the swinging bodies 6 are swung by a prescribed angle θ to moving bodies 5, and are put in an outward downward inclined condition, and swinging except for it is regulated by regulating bodies 7. At this time, since the respective needle bodies 3 are put in an outward downward inclined condition, the cloth sheet B is slightly tensioned, and is put in an engaging condition. When the moving driving machine 8 is actuated further, the swinging bodies 6 and the needle bodies 3 are put still in its condition, and things except for the moving bodies 5 move outside to a base body 2, and the respective needle bodies 3 are put in a holding position. Therefore, the cloth sheet B is straightly tensioned, and is put in a condition of not falling off from the respective needle bodies 3.
