PURPOSE:To prevent vibration, by arranging blocks superimposed in the longitudinal direction of a belt element made of metal, and interposing between the adjacent blocks an elastic member having an elastic restoring force in the longitudinal direction of the belt. CONSTITUTION:A belt element 11 is formed by stacking belt-like metal sheets 15, and is inserted into grooves 22 and 23 of each block 12. There is provided between the adjacent blocks 12 an elastic member 13 curved in the longitudinal direction of a belt 10 and having an elastic restoring force in the longitudinal direction of the bolt 10. Accordingly, it is possible to prevent the clearance between the blocks from being collected at a certain position and thereby prevent the generation of abnormal vibration.
