PROBLEM TO BE SOLVED: To provide a foot pedal structure allowing a user to train toes by moving pedals of a bicycle or a training device.SOLUTION: A foot pedal structure has a length in the front-back direction of a length from a toe tip to a metatarsus bone head part vicinity, and is rotated around a crankshaft. The foot pedal structure is such that: a projection-shaped part which abuts a recess of the root of the toes on a position nearly the same as that of a pedal shaft in the front-back direction, and has a dimension allowing to grip the toes is formed on at least one surface side of the pedal of the foot pedal structure; and relief parts allowing bending of the toes and the metatarsus bone head part vicinity around the root of the toes when moving the pedals at the root of the toes are formed in the pedal surfaces at the front-back sides of the projection-shaped part.SELECTED DRAWING: Figure 1

    【課題】自転車やトレーニング機器のペダルをこぐことにより足指を鍛えることができる足踏みペダル構造体を提供することを課題とする。【解決手段】前後方向の長さが足指先端部から中足骨頭部近傍までの長さを有し、クランク軸を中心に回転する足踏みペダル構造体であって、前記足踏みペダル構造体のペダルの少なくとも一面側に、前後方向でペダル軸と略同じ位置に足指の付け根の凹部を当接させる、足指が掴みやすい大きさを有する凸形状部が形成され、前記凸形状部の前後側の前記ペダル面には、足指の付け根で前記ペダルをこぐときの、前記足指の付け根を中心とした足指や中足骨頭部近傍部の屈曲を許容する逃がし部が形成されている足踏みペダル構造体により課題解決できた。【選択図】 図1
