In the conventional structure, depending on the tension adjustment of the chain 2, the distance between the chain wheel 1 and the mounting plate 5 may become long, and in that case, the distance between the metal fitting 7 and the mounting plate 5 shown in FIG. 5 becomes long. Therefore, the bending rigidity of the adjustment screw 3 is reduced, and there is a possibility that the strength thereof may become unstable with respect to the load from the chain 2 that is applied to the chain wheel 1. Furthermore, when nuts 4A and 4B are loosened to adjust the tension of the chain 2, the adjustment screw 3 rotates and the parallelism between the chain wheel 1 and the chain 2 becomes incorrect. There was an operational inconvenience in that the nuts 4A and 4B had to be tightened while maintaining the parallelism between the chain 1 and the chain 2.
