    • A human powered drive units each including a pair of a rotatable member having a sprocket and a supporting member having a sprocket, which are arranged up and down, and including a chain extended around the rotatable member and the supporting member, are disposed at left and right sides, respectively. The left and right rotatable members 1, 100 are fixed on a driving shaft 15. A chain ring 6 on which the load is applied is mounted on the driving shaft between upper rotatable member 1 and rotatable member 100. In each of the units, constraining means including a free crank (10 for the right-hand unit, and 1000 for the left-hand unit) and arm (11 for the right-hand unit, and 1100 for the left-hand unit), is provided so as to maintain perpendicularity of a shaft of the pedal relative to the plane in which the chain moves. By the rider kicking the pedal along the closed orbit including a linear orbit portion, the force transmitted to the pedal from the foot of the rider is efficiently converted to a rotational force in a longer period of time, thus increasing the power input.
    • 一个人机动力驱动单元,每个包括一对具有链轮的旋转构件和具有链轮的支撑构件,其上下布置,并且包括围绕可旋转构件和支撑构件延伸的链条,并且 右侧分别。 左右可旋转构件1固定在驱动轴15上。施加负载的链环6安装在上可旋转构件1和可旋转构件100之间的驱动轴上。在每个单元中,约束 包括自由曲柄(右侧单元为10,左侧单元为1000)和手臂(右侧单元为11,左侧单元为1100),以保持 踏板的轴相对于链移动的平面的垂直度。 由骑手沿着包括直线轨道部分的封闭轨道蹬踏踏板,从骑车人的脚传递到踏板的力被有效地转换成更长时间段的旋转力,从而增加了动力输入。
