PROBLEM TO BE SOLVED: To reduce stress applied to a belt as a belt walk is made. SOLUTION: A rib 31 which extends in a direction of circulating movement is stuck on an inner peripheral surface of a conveying belt 16. The rib 31 is guided by a guide member 32 in a pulley shape. The guide member 32 is fitted to a shaft portion 17C of a driving roller 17B so as to be able to move along the width of the conveying belt 16. When the rib 31 is inferior in straightness, the guide member 32 moves as shown by an arrow X in accordance with a curving shape of the rib 31, which then deforms. Consequently, the influence of straightness of the rib 31 is not exerted on the conveying belt 16 and stress on the composition surface of the conveying belt 16 and rib 31 is reducible.
