PROBLEM TO BE SOLVED: To provide a hub ratchet for a bicycle smooth in matching interlocking, significantly improved in accuracy, and increased in conduction effect of the hub ratchet.SOLUTION: A hub ratchet structure includes a hub seat 10 and a free hub body seat 20, and an interlocking ring 30, a passive ring 40, and a driving ring 50 are disposed between the hub seat and the free hub body seat. The passive ring is fitted and assembled in a hollow part of the interlocking ring to be matched and interlocked. Engagement saw teeth 42 are disposed on a circumference of an outer wall of the passive ring, and the driving ring is fitted to the free hub body seat to be simultaneously rotated. The driving ring is provided with detent saw teeth 53 toward an end face of the hub seat, and engaged with the engagement saw teeth of the passive ring by the detent saw teeth to be interlocked. A pitch of a gear of the detent saw teeth is longer than a pitch of a gear of the engagement saw teeth, and retreating planes of equal intervals are respectively formed between the detent saw teeth.SELECTED DRAWING: Figure 2

    【課題】自転車用ハブラチェットで合致連動がスムーズで且つ精度が大幅に増進され、更にハブラチェットの伝導効果が増加されたものを提供する。【解決手段】ハブ座10とフリーハブボディ座20とを含み、ハブ座とフリーハブボディ座との間に連動リング30と、受動リング40と、駆動リング50とが設けられる。受動リングは連動リングの中空部分に合わせて組み込まれ合致して連動される。受動リングの外壁の円周には噛み合い鋸歯42が設けられ、駆動リングはフリーハブボディ座内に嵌め込まれて同時回転状態にされる。駆動リングはハブ座の端面に向かって戻り止め鋸歯53が設けられ、戻り止め鋸歯によって受動リングの噛み合い鋸歯同士と互いに噛み合って連動される。戻り止め鋸歯の歯車のピッチが噛み合い鋸歯の歯車のピッチより長く、各戻り止め鋸歯間に等間隔の退避平面を形成する。【選択図】図2
