PROBLEM TO BE SOLVED: To quickly and easily manufacture a three dimensional object having a cavity section in it which has been manufactured by a skilled worker by providing a holding/moving device moving the three dimensional object having the cavity section in the three-dimensional directions. SOLUTION: When the needle 70 of a sewing machine 62 approaches a first side edge section of a circular arc-shaped headrest, a frame rotary shaft 21 is rotated to rotate the headrest in the same direction, the first side edge section is guided onto a throat plate base 72, and the rotation of the frame rotary shaft 21 is stopped when the first side edge section is set to the parallel state with the throat plate base 72. A lower brace body 32 and a balloon support body 46 are rotated by a lower brace support shaft 28, and an upper brace body 42 is rotated by an upper brace support shaft 38. A movement support 14 is moved along the upper face 12A of an XY table 12 to follow the circular arc-shaped first side edge section, thereby the first side edge section is smoothly sewn. |
