PROBLEM TO BE SOLVED: To provide a capstan roll which hardly cracks even if stressed at the time when rotations are repeated for wire drawing and which can perform a wire drawing work for a long term.SOLUTION: A capstan roll of the present embodiment is made of ceramics and includes: externally, a slide contact face having an external diameter gradually enlarged from one side to the other side; and a fitting hole internally for a revolving shaft. An opening for said fitting hole inside the capstan roll is a fastening part with the fastening member, and a recess is formed at a position corresponding to the contour of said fastening member in the contact face with said fastening member.SELECTED DRAWING: Figure 2
【課題】 伸線のための回転が繰り返されたときに掛かる応力を受けたとしても割れるおそれが少なく、長期間にわたって伸線作業できるキャプスタンロールを提供する。【解決手段】 本実施形態のキャプスタンロールは、セラミックスからなり、外部に、外径が一方端から他方端に向って段階的に大きくなる摺接面と、内部に、回転軸の挿入孔とを備え、前記内部における前記挿入孔の開口部が締結部材との締結部であり、前記締結部材との接触面における前記締結部材の輪郭に相当する位置に凹部を有する。【選択図】 図２
