To provide a swinging rotation transmission assemblage for bicycles having a simple structure and a small number of components, low in cost and capable of diminishing a bend of a knee to such an extent that a load on a leg which depresses a pedal is alleviated.SOLUTION: The length of coupling rods 6a and 6b which rotate cranks 4a and 4b of a swinging rotation transmission assemblage for bicycles which is mounted on a bicycle is larger than the length of the cranks 4a and 4b. Therefore, a distance at which the coupling rod 6a is instantaneously swung and moved forward together with the pedal 7a to such an extent that the coupling rod 6a on the side on which the pedal 7a is not depressed can rotate the crank 4a from an apex gets longer, so that while the pedal 7a is depressed with the coupling rod being swung and moved to be on the side on which the pedal 7a is depressed, a bend of a knee can be diminished to such an extent that a load on the leg which depresses the pedal 7a is alleviated. The pedal 7b on the opposite right side can be depressed in the same manner.SELECTED DRAWING: Figure 1

    【課題】構造が簡単で部品点数が少なく、低コストで、ペダルを漕ぐ脚の負担が軽減されるところまで膝の曲がりを小さくさせることができる自転車用揺動回転伝達装置を提供する。【解決手段】自転車に実装した自転車用揺動回転伝達装置の、クランク4a、4bを回転させる連結棒6a、6bの長さがクランク4a、4bの長さよりも長くなっていることによって、ペダル7aを漕がない側の連結棒6aがクランク4aを頂点から回転させられるところまで連結棒6aをペダル7aとともに、前方に瞬時に揺動移動させる距離が長くなるため、揺動移動させてペダル7aを漕ぐ側に入れ替わったペダル7aを漕いでる間では、ペダル7aを漕ぐ脚の負担が軽減されるところまで膝の曲がりを小さくさせることができる。反対側の右側も同様にペダル7bを漕ぐことができる。【選択図】図1
