To provide a bicycle for an inferior limb functional disorder that is mainly targeted for a driver having laterally asymmetrical functional disorder in their inferior limbs and that brings about rehabilitation effect on an inferior limb on the paralysis side by reducing muscular power load on the inferior limb on the paralysis side to a certain degree and increasing muscular power load on the inferior limb on the healthy side to a certain degree.SOLUTION: A bicycle includes a crank lever and a sprocket with the crank lever fixed thereto. The crank lever is fixed at a position eccentric from the center of the sprocket, and step-in force of the crank lever can be adjusted via the amount of eccentricity, and a phase of the step-in force can be also adjusted via the angle of the eccentricity. A chain tensioner is further provided for giving tensile force to a chain that engages with the sprocket and a chain wheel. The chain tensioner has parallel three guide wheels, and among the three guide wheels, a central one and two at both ends are energized in opposite directions.SELECTED DRAWING: Figure 10

    【課題】下肢に左右非対称の機能障害を持つ運転者を主な対象として、麻痺側の下肢の筋力負荷を一定程度下げ、健常側の下肢の筋力負荷を一定程度上げることで麻痺側の下肢にリハビリ効果をもたらす、下肢機能障害用自転車を提供する。【解決手段】クランクレバーと、クランクレバーが固定されたスプロケットと、を備え、クランクレバーは、スプロケットの中心から偏心した位置に固定され、その偏心量によって、クランクレバーの踏込力を調整可能とし、また、その偏心角によって踏込力の位相を調整可能とした。さらに、スプロケット、及びチェーンホイールと係合するチェーンに張力を付与するチェーンテンショナーを備え、このチェーンテンショナーは、並列する三つのガイドホイールを有し、三つのガイドホイールのうち、中央の一つと、両端の二つは逆方向に付勢される。【選択図】図10
