It is difficult to maintain the same speed and synchronous operation at the same time. In addition, it is not easy to maintain the horizontal attitude of the loading platform T and circulate, because the loosening of each chain occurs. In the prior art, it is difficult to arrange the positions of the annular outer guide rail G1 and the annular inner guide rail G2 together with the phase difference between the horizontal separation distance and the vertical separation distance between the outer roller R1 and the inner roller R2. Since the dividing path P is provided at the both end reversing portions of the inner guide rail G2, it is difficult to hold the horizontal position of the loading table by shaking when the inner roller R2 passes through the dividing path P. .
