    • To provide a bicycle with an assisting power apparatus which is less expensive and light and can assist the human power with power of a motor. A hollow torque transmission member (8) in the form of a pipe or a tube is fitted for relative rotation on an outer periphery of a crankshaft (4) having base ends of a pair of pedal arms (5) integrally mounted at the opposite ends thereof and a drive sprocket wheel (12) is integrally fitted at an end of the hollow torque transmission member (8) while a motor one-way clutch (14) is provided on the hollow torque transmission member (8) adjacent the drive sprocket wheel (12) and the crankshaft (4) is connected to the other end of the hollow torque transmission member (8) via a pedaling force one-way clutch (10), and an input end of the motor one-way clutch (14) is connected to an output of a motor (20) via a speed reducing mechanism (15, 16, 17, 18 and 19) and a magneto-striction type torque sensor (28) is disposed on an outer periphery of the hollow torque transmission member (8).
    • 提供一种具有辅助动力装置的自行车,其价格便宜且轻便,并且可以利用电动机的动力辅助人力。 在曲轴(4)的外周上装配有管或管形式的空心扭矩传递部件(8)以便相对旋转,该曲轴具有一体地安装在相对端的一对踏板臂(5)的基端 在中空扭矩传递部件8的端部一体地安装有驱动链轮12,在中空扭矩传递部件8上设置有与驱动链轮相邻的电动单向离合器14, (12),曲轴(4)通过踏力单向离合器(10)与空心扭矩传递部件(8)的另一端连接,电动机单向离合器(14)的输入端与曲轴 经由减速机构(15,16,17,18,19)与马达(20)的输出连接,在该中空转矩传递部件(20)的外周配置有磁致伸缩式转矩传感器(28) (8)。
