WIRE REEL
PROBLEM TO BE SOLVED: To provide a wire reel which can detect light transmitted through a transmission hole, without being affected by irregularities on a wire reel surface, and which can increase accuracy of detection of rotational information.SOLUTION: A wire reel includes: a hub part 43 that is formed in a cylindrical shape; flanges 44 and 45 that are provided on both sides of the hub part 43; an inner cylinder 40 that is almost coaxially formed in a central part of the hub part 43; and a side wall 60 that connects the inner cylinder 40 and the hub part 43 together. A recess 47 is formed of the inner cylinder 40, an inside surface of the hub part 43, and the side wall 60. A plurality of translucent parts 64, which allow light transmission, are formed in a circumferential direction of the side wall 60 within the recess.
【課題】ワイヤリール表面の凹凸に影響されることなく透過孔を透過した光を検出することができ、回転情報の検出精度を向上させることができるワイヤリールを提供する。【解決手段】円筒形状に形成されたハブ部４３と、上記ハブ部４３の両側に設けられたフランジ４４，４５と、上記ハブ部４３の中央部に略同一軸心で形成された内筒４０と、上記内筒４０と上記ハブ部４３とを連結する側壁６０と、を備え、上記内筒４０と上記ハブ部４３の内側面と上記側壁６０とによって凹部４７を形成し、上記凹部内の上記側壁６０の周方向に、光を透過させる複数の透光部６４を形成した。【選択図】図１５
