Zusammenfassung:To provide a spool, a tightening device with the spool, and a coupling method of the spool and a lace.SOLUTION: A first free end and a second free end of a lace are routed in subtended directions along a first routing path and a second routing path, respectively. The first routing path and the second routing path are designed in separate grade crossing structure. Even if the first free end and the second free end are routed simultaneously, they will not collide with each other. When the lace is knotted, there is no strict requirement for length of a reserved tail of the lace. Even if the tail of the lace is left outside a housing, the tail of the lace can be wound onto the spool by rotating the spool, without affecting the normal operation of the tightening device. Thereby, the spool, the tightening device with the spool, and the coupling method of the spool and the lace according to the present invention are convenient and quick, and achieve a high accuracy rate of lace coupling and a low technical difficulty.SELECTED DRAWING: Figure 6 【課題】スプール、スプールを含む締付装置、及び、スプールと紐との結合方法の提供。【解決手段】第一紐自由端及び第二紐自由端は、それぞれ第一紐走行経路及び第二紐走行経路に沿って対向方向の紐通しを行い、第一紐走行経路と第二紐走行経路とは、分離して立体交差しており、2つの自由端が同時に紐通しを行っても、互いに衝突することがなく、紐を結ぶとき、確保される尾部の長さについては、厳しい要件が求められず、ケースの外部に残されている場合でも、締付装置の正常な動作に影響を与えることなく、スプールを回転させることで、残されている紐をスプールに巻き付けることができるため、本発明によるスプール、スプールを含む締付装置、及び、それらと紐との結合方法は、便利で迅速であり、紐通しの正確率が高く、技術的難易度が低い。【選択図】図6
