PROBLEM TO BE SOLVED: To provide a gear change stage switching device which eliminates the need for replacement work and adjustment work of wires, minimizes an increase in manufacturing costs, and requires only a small mounting space.SOLUTION: Provided is a gear change stage switching device 30 to be mounted to a bicycle, on which an internal transmission is disposed having a gear change stage switching body 26 for switching gear change stages by retracting from a central part or the outer periphery of an axle 25 along a shaft center X direction of the axle 25, on a hub 16 of a rear wheel. The gear change stage switching device includes: a gear change stage switching motor 33 for generating drive power for switching gear change stages; and a deceleration mechanism for decelerating rotation of the gear change stage switching motor 33. On the deceleration mechanism, a driving output body 40 is disposed to which decelerated force is transmitted and output and which is linked to the gear change stage switching body 26 in order to be moved, so that rotational drive power transmitted from the gear change stage switching motor 33 to the driving output body 40 is transmitted to the gear change stage switching body 26 not only in a direction retracting from/advancing into the axle but also in a direction projecting from the axle.SELECTED DRAWING: Figure 4

    【課題】ワイヤの交換作業や調整作業が不要となるとともに、製造コストの上昇を最小限に抑えることができ、しかも、取付スペースも少なくて済む変速段切換装置を提供する。【解決手段】後輪のハブ16に、車軸25の中心部または外周から車軸25の軸心X方向に沿って出退して変速段を切り換える変速段切換体26を有する内装変速機が設けられた自転車に取付けられる変速段切換装置30であって、変速段切換用の駆動力を発生する変速段切換用モータ33と、変速段切換用モータ33の回転を減速する減速機構と、を備え、前記減速機構に、減速された力が伝達されて出力され、変速段切換体26に連結されて移動させる駆動用出力体40が設けられ、前記変速段切換用モータ33から駆動用出力体40に伝達された回転駆動力が、変速段切換体26に、車軸内に退入する方向だけでなく車軸から突出する方向にも伝達される。【選択図】図4
