As a result, the shaft 20 generates a revolution force to rotate a frame 10. And the shaft 16 revolves by the rotation of the frame as well as rotates by itself. Therefore, the shaft 16 revolves at an absolute rotary angle. Consequently, one end of the cable 15 wound on the shaft 16 is released gradually, and the released part is wound on the shaft 11. And the other end of the cable 15 wound on a fixed shaft 12 is released gradually and reseased part is wound on the shaft 16.
