PROBLEM TO BE SOLVED: To highly efficiently convert a reciprocating motion of an irregular stroke to a rotation motion, especially in a bicycle, to enable improving inefficiency near upper and lower fulcrums in a crank pedal type, and improving a degree of freedom of a design, and to make natural energy including a human power as a reciprocating motion of an irregular stroke usable for electric power generation with a simple structure.SOLUTION: Two engagement teeth 210 and 220 which mutually perform an opposite reciprocating motion are mutually and exclusively engaged with a front engagement surface 110 and a back engagement surface 120 of a chain 100, and the chain is linearly driven so as to convert to a rotation motion with a sprocket 500.SELECTED DRAWING: Figure 1
【課題】不規則ストロークの往復運動を高効率に回転運動に変換する。特に自転車に於いて、クランクペダル式では上下支点付近での非効率を改善し、デザインの自由度を向上させる事を可能にする。また、不規則ストロークの往復運動である人力を含む自然エネルギーを、簡単な構造で発電等に利用可能にする。【解決手段】チェーン100の前噛合面110と後噛合面120に、相互に反対往復運動する二つの噛合歯210、220を相互排他的に噛合させ、チェーンを直線的に運動させて、スプロケット500で回転運動に変換する。【選択図】図1
