The invention provides a bicycle power transmission device capable of stably transmitting torque. A power transmission device (100) is provided with an output rotating body (2), first and second input rotating bodies (3a, 3b), an elastic member (4), a sprocket section (6), and a crank arm (7). The output rotating body (2) has a first accommodating portion (21) penetrating in the axial direction. The first and second input rotating bodies (3a, 3b) each have a second housing portion (31a, 31b). The first and second input rotating bodies (3a, 3b) are disposed so as to sandwich the output rotating body (2) in the axial direction. The elastic member (4) is disposed in the first housing section (21) and the second housing sections (31a, 31b). The elastic member (4) elastically connects the first and second input rotating bodies (3a, 3b) and the output rotating body (2). The sprocket part (6) is provided to the output rotating body (2). The crank arm (7) is attached to the first input rotating body (3a).

    本发明提供自行车用动力传递装置,能够稳定地传递转矩。动力传递装置(100)具备输出旋转体(2)、第一及第二输入旋转体(3a、3b)、弹性部件(4)、链轮部(6)以及曲柄臂(7)。输出旋转体(2)具有沿轴向贯通的第一容纳部(21)。第一及第二输入旋转体(3a、3b)分别具有第二容纳部(31a、31b)。第一及第二输入旋转体(3a、3b)配置为在轴向上夹着输出旋转体(2)。弹性部件(4)配置于第一容纳部(21)及第二容纳部(31a、31b)内。弹性部件(4)将第一及第二输入旋转体(3a、3b)与输出旋转体(2)弹性地连结。链轮部(6)设置于输出旋转体(2)。曲柄臂(7)安装于第一输入旋转体(3a)。
