Claims (1)
達する第２駆動系とを備え、前記第１屹動系を自転車の
幅方向中心部に、また、前記第２駆動系を前記後輪の一
側方に配置して、前記第１駆動系を前記第２駆動系に連
動部を介して連動連結すると共に、前記第１駆動系の長
さを、クランクアームの長さより長くし、前記連動部を
、前記クランクアームの先端に設けるペダルの回転軌跡
外に配置して、前記ペダル間の間隔を狭くしたことを特
徴とする自転車の駆動機構。It includes a first drive system driven by a crank and a second drive system that transmits driving force to the rear wheels, with the first drive system located at the center in the width direction of the bicycle, and the second drive system The first drive system is disposed on one side of the rear wheel, and the first drive system is interlocked and connected to the second drive system via an interlocking part, and the length of the first drive system is longer than the length of the crank arm. The bicycle drive mechanism is characterized in that the interlocking portion is disposed outside the rotation locus of the pedals provided at the tip of the crank arm, so that the distance between the pedals is narrowed.
