PROBLEM TO BE SOLVED: To prevent a load from dropping off by raising a belt at an arc-shaped transfer path inwardly so as to lower its outside at the time of few loads. SOLUTION: A roller 4 is disposed above a belt 1 on the inward side of an arc-shaped transfer path, and a load retaining member 3 is disposed above the belt 1 on the outward side of the arc-shaped transfer path, which is formed out of a rubber sheet material or the like shaped so as to cover the path. Both of them are jointed by an rotating arm 5. When the inner part of the belt is raised, the roller 4 is pushed up and the load retaining member 3 is pushed down so as to cover a load. It is thus possible to prevent the load from dropping off.
