PROBLEM TO BE SOLVED: To provide a shoe having low friction resistance and excellent abrasion resistance.SOLUTION: A chain 4 is stretched between a sprocket 1 and sprockets 2, 3. A tensioner device 5 is arranged outside of a portion in a slack side of the chain 4, and a guide 8 is arranged in a portion in a tension side of the chain 4. The tensioner device 5 includes a tensioner 6 and a lever 7. The lever 7 includes a body 71, and a shoe 72 mounted on the body 71. The guide 8 includes a body 81, and a shoe in sliding contact with a running surface of the chain 4. This shoe and the shoe 72 contain a synthetic resin including a benzene ring in a molecular skelton.SELECTED DRAWING: Figure 1 【課題】摩擦抵抗が小さく、かつ良好な耐摩耗性を有するシューを提供する。【解決手段】スプロケット１とスプロケット２，３との間にチェーン４が掛け渡されている。チェーン４の弛み側となる部分の外側にはテンショナ装置５が配置され、チェーン４の張り側となる部分にはガイド８が配置されている。テンショナ装置５はテンショナ６と、レバー７とを備え、レバー７は本体７１と、本体７１に取り付けられたシュー７２とを備える。ガイド８は、本体８１とチェーン４の走行面に摺接するシューとを備える。該シュー及びシュー７２は、分子骨格中にベンゼン環を含む合成樹脂を含む。【選択図】図１
