PROBLEM TO BE SOLVED: To provide an assembly structure for a hub ratchet that enhances certainty and safety of pedalling and also suppresses wasting of motion energy to prolong a use lifetime.SOLUTION: An assembly structure for a hub ratchet includes a hub seat 10, an interlocking ring 20, a sleeve 30, and a ratchet unit 40. The interlocking tooth part 21 of the interlocking ring 20 is a multi-tooth, short-tooth-distance type, and also has up to 155 teeth, and the ratchet unit 40 has meshing teeth installed at respective claw parts corresponding to the interlocking tooth part 21 as a short-tooth distance type as well. Consequently, a slide distance of the meshing teeth at a tooth end of the interlocking tooth part 21 is advantageously shortened and intervals of meshing interlocking between the ratchet unit 40 and the interlocking ring 20 are also shortened, so a state of meshing interlocking can be quickly obtained, and further pedaling having a narrow gap is formed so as to enhance certainty of the pedaling greatly and safety.SELECTED DRAWING: Figure 2

    【課題】ペダリングの確実度と安全性を高め、無駄な運動エネルギーの消耗を抑えて使用寿命を延長するハブラチェットの組立構造を提供する。【解決手段】ハブラチェットの組立構造は、ハブ座10と、連動リング20と、スリーブ30と、ラチェットユニット40とを含む。上記連動リング20の連動歯21は多歯数、短歯距離の方式より構成され、しかも歯数は最多155本もあり、ラチェットユニット40の各つめ部分は連動歯21に対応して同様に歯距離が短い方式で噛み合い歯が設置される。これにより噛み合い歯の連動歯21の歯端での滑動距離が有効に縮められるのでラチェットユニット40と連動リング20間の噛み合い連動の間隔も縮められるため、噛み合い連動の状態が迅速に達成でき、さらに狭い隙間のペダリングが形成され、大幅にペダリングの確実度が高められ、安全性も兼ねられる。【選択図】図2
