To provide a hub unit for a bicycle which enables a wheel unit to be preferably coupled to a hub body, and to provide a wheel assembly for a bicycle.SOLUTION: A rotating body which is braked by a brake device is coupled to a hub unit for a bicycle. The hub unit includes: a hub body which rotates around a hub shaft; and a rotating body coupling part which couples the rotating body to the hub body. The hub body includes: a first coupling part including a male screw to which a female screw of a wheel unit is coupled; a second coupling part to which a restriction member for restricting relative rotation of the first coupling part and the wheel unit in one direction is coupled; and a taper part in which an outer diameter becomes larger as it gets away from the first coupling part in a direction along a center axis of the hub body so as to restrict relative rotation of the first coupling part and the wheel unit in the other direction.SELECTED DRAWING: Figure 3

    【課題】ホイールユニットをハブ本体に好適に連結できる自転車用ハブユニットおよび自転車用ホイールアセンブリを提供する。【解決手段】自転車用ハブユニットは、制動装置によって制動される回転体が連結される自転車用ハブユニットであって、ハブ軸まわりで回転するハブ本体と、前記回転体を前記ハブ本体に連結する回転体連結部と、を含み、前記ハブ本体は、ホイールユニットの雌ねじが連結される雄ねじを含む第1結合部と、前記第1結合部と前記ホイールユニットとの一方向の相対的な回転を規制する規制部材が連結される第2結合部と、前記第1結合部と前記ホイールユニットとの他方向の相対的な回転を規制するように、前記ハブ本体の中心軸心に沿う方向において前記第1結合部から離れるにつれて外径が大きくなるテーパ部とを含む。【選択図】図3
