PURPOSE:To provide a difference in horizontal direction between the carry-in and carry-out positions for objects to be transported, by coupling together No.1 and No.2 frames supporting a drive roller and a follower roller with possibility of bending in the horizontal direction, and by absorbing elongation and contraction of the belt with an expansive absorption roller. CONSTITUTION:Pins 6C1, 6C2 are set in a beam 11 at the upper front and rear walls 9, 9 of supporting frame 7 and a beam 12 at the bottom of both side walls 8, 8 and said supporting frame 7 is borne by a coupling mechanism in such a way as rotatable horizontally. The tension side outside surface of a belt 5 led in from guide parts 9A, 9B of the supporting frame 7 recessedly is wound on an expansive absorption roller 13A, while the loose side outside surface of the same belt 5 led in from guide parts 10A, 10B recessedly is wound on another roller 13B, If the follower roller side is pressed, a frame 4 bends with respect to a frame 3 with the pins 6C1, 6C2 as fulcrum. Accordingly, elongation and contraction of the belt 5 at its ends in width direction is absorbed through rotation of the rollers 13A, 13B round vertical axis through mechanisms 18A, 18B.
