To enhance climbing performance of a bicycle without auxiliary power.SOLUTION: To solve the problem, pedals are disposed linearly symmetrically on a line connecting a front wheel and a rear wheel by limiting a movement of a crank from a conventional circular motion to an arcuate motion in order to prevent the pedals from passing through the upper and lower dead centers, a configuration in which when one of the pedal lowers, the other is raised in synchronization with this is provided, and a one-way clutch that transmits only rotation in a lowering direction of the pedal is transmitted to a crank sprocket is disposed.SELECTED DRAWING: Figure 2
【課題】補助動力無しに自転車の登坂性能を上げる。【解決手段】上・下死点をペダルが通過しないようにする為に、クランクの動きをこれまでの円運動から円弧運動に制限して前輪と後輪を結ぶ線に線対象にペダルを配置し、片側のペダルが下がるとこれに同期してもう一方が上がる構成を与え、ペダルが下がる方向の回転のみをクランクスプロケットに伝動する一方向クラッチを配置して課題を解決する。【選択図】図2
