    • PROBLEM TO BE SOLVED: To provide a gear shift device of improved operation precision.SOLUTION: A gear shift device 10 with a motor for a bicycle includes a deformable articulation type motion mechanism 20 which is intended so as to be fixed to a frame T of the bicycle, a chain guide 40 which is held by the deformable articulation type motion mechanism and can take a different position to the frame T of the bicycle according to a different operation state of the motion mechanism, and a motor member 50 attached to the motion mechanism in such a manner as contains motor casings 51;151 and a master drive shaft 52 which directly protrudes from the motor casings, to deform the articulation type motion mechanism such that it takes a different operation state. The master drive shaft cannot be rotated and translation motion is possible in axial direction to the motor casing 51.
    • 要解决的问题:提供一种改进的操作精度的换挡装置。解决方案:具有用于自行车的电动机的换档装置10包括可变形的铰接式运动机构20,其可以固定到框架T的框架T 自行车,链条引导件40,其由可变形的铰接型运动机构保持,并且可以根据运动机构的不同操作状态,将自行车的框架T置于不同的位置;以及马达部件50,其安装在运动 机构以包含马达壳体51; 151和从马达壳体直接突出的主驱动轴52的方式使接合型运动机构变形,使得其处于不同的运行状态。 主驱动轴不能旋转,并且在轴向方向上可以向马达壳体51进行平移运动。
