も、その必要性がとぼしいため採用し難い。 In bicycles equipped with a belt transmission device having an automatic tension adjustment mechanism as disclosed in Japanese Patent Publication No. 58-47592, there is a risk that the automatic tension adjustment mechanism may be deteriorated. 6 is also a cause of a decrease in durability. In such cases, it is considered desirable to adopt a full-face case, but since an endless toothed belt is used, the structure of the full-face case itself becomes complicated, the assembly work is complicated, and the weight increases. It is difficult to adopt this method because it is unlikely to be necessary due to the difference from the above-mentioned chain.
