摘要 一種自行車輪轂基本上具有輪轂軸、輪轂殼、鏈輪支撐體、第一棘輪構件、及第二棘輪構件。輪轂殼被可繞旋轉軸線旋轉地安裝在輪轂軸上。鏈輪支撐體被可旋轉地安裝在輪轂軸上以繞旋轉軸線旋轉。鏈輪支撐體具有有第一螺旋花鍵的外周邊表面。第一棘輪構件具有至少一個第一棘輪齒、及與第一螺旋花鍵配合的第二螺旋花鍵。第二棘輪構件具有與所述的至少一個第一棘輪齒配合的至少一個第二棘輪齒、及接合輪轂殼的輪轂殼接合部份。鏈輪支撐體的外周邊表面具有引導部份,此引導部份在滑行的情況下將第一棘輪構件朝向輪轂殼引導。 A bicycle hub basically has a hub axle, a hub shell, a sprocket support body, a first ratchet member and a second ratchet member. The hub shell is rotatably mounted on a hub axle about a rotational axis. The sprocket support body is rotatably mounted on the hub axle to rotate around the rotational axis. The sprocket support body has an outer peripheral surface with a first helical spline. The first ratchet member has at least one first ratchet tooth and a second helical spline mating with the first helical spline. The second ratchet member has at least one second ratchet tooth mating with the at least one first ratchet tooth and a hub shell engagement portion that engages the hub shell The outer peripheral surface of the sprocket support body has a guiding portion that guides the first ratchet member toward the hub shell while coasting.
