PROBLEM TO BE SOLVED: To easily remove and insert a belt from/to a guide member while securing continuous rotation and transfer of a belt. SOLUTION: An upper guide 3 and a lower guide 4 are provided above and under the belt 2 for preventing deflection of the belt 2. For the belt 2 and the upper guide 3, a belt groove 2a continuous in the transfer direction is engaged with an upper guide projection 3a to prevent lateral deflection of the belt. In a belt side surface of the lower guide 4, an insertion/removal groove 4a continuous in the transfer direction having a dent of a larger width than the belt groove 2a is provided, so that by lateral direction external action, the belt 2 can be inserted to/removed from between the upper guide 3 and the lower guide 4 using the insertion/removal groove 4a for a guide.
