To provide a simple actuator device for bicycle gear shift from the viewpoint of miniaturization and the total number of components.SOLUTION: An actuator device 100 includes: an operation link mechanism 101; a drive member 120 for controlling deformation of the mechanism; and a coupling/uncoupling mechanism 150 arranged to operate between a transmission element 122 and a connection rod 102. The mechanism includes a first member 160 capable of being rotated around a rotational axis X together with the transmission element 122, a second member 170 capable of being rotated around the rotational axis X together with the connection rod and an elastic element 180 applying a prescribed preload stress to the first and second members. The mechanism, when exposed to a stress under the prescribed preload stress, is set to a coupling operation state and thus the first and second members can be rotated together around the axial center X and when exposed to a stress in excess of the prescribed preload stress, is set to an uncoupling operation state and thus the first and second members can be rotated against each other.SELECTED DRAWING: Figure 2

    【課題】小型かつ部品総数の点から単純な自転車ギアシフトのアクチュエータ装置の提供。【解決手段】アクチュエータ装置100は、作動リンク機構101と、同機構の変形を制御する駆動部材120と、伝動エレメント122と接続ロッド102間に動作可能に配置された留め/切離し機構150と、を備える。該機構は、伝動エレメント122と回転軸心X回りに一体回転可能な第1の部材160、接続ロッドと一緒に回転軸心Xを中心として回転可能な第2の部材170、並びに第1及び第2の部材に所定の予圧応力を加える弾性エレメント180を含む。機構は、前記所定の予圧応力を下回る応力に曝されると留め動作状態に設定されて第1と第2の部材が軸心X周りに一体回転可能となり、前記所定の予圧応力を上回る応力に曝されていると切離し動作状態に設定されて第1の部材と第2の部材とが互いに対して回転可能となる。【選択図】図2
