PROBLEM TO BE SOLVED: To provide an actuation device of a control cable of a front derailleur of a bicycle that may perform precise gearshifting.SOLUTION: An actuation device (10) comprises: a casing (11) fixed to handlebars; a cable-winding bush (13) installed in the casing; a rotating member (14) rotating coaxially therewith; and a stationary member (18). One of the rotating member and the stationary member comprises pointers (15, 16), and the other comprises fastening tracks (19) to engage with the pointers. The fastening tracks (19) comprise a plurality of stop areas, and additional stop areas are provided outside the tracks. The cable-winding bush (13) rotates by a predetermined angle correspondingly to a movement of the pointers between two stop areas so as to actuate a front derailleur (300).SELECTED DRAWING: Figure 3

    【課題】精密にギアシフトを行い得る自転車フロントディレイラ制御ケーブル用作動装置を提供する。【解決手段】作動装置(10)は、ハンドルバーに固定されるケーシング(11)と、その中に装着されるケーブル巻取ブッシュ(13)と、これと同軸で回転する回転部材(14)と、固定部材(18)とを備える。回転部材と固定部材は、いずれか一方がポインタ(15,16)を、他方がポインタの係合する締結軌道(19)を備える。締結軌道(19)は複数の停止領域を備え、軌道外にも追加停止領域が設けられている。二つの停止領域間のポインタの移動に対応してケーブル巻取ブッシュ(13)は所定角度回転し、フロントディレイラ(300)を作動させる。【選択図】図3
