如圖44中所見,軸向方向D2包括第一軸向方向D21及與第一軸向方向D21相反之第二軸向方向D22。偏置力F5在第一軸向方向D21上自偏置構件84施加至收納構件94。偏置構件84之偏置力F5使收納構件94、第一棘輪構件80、第二棘輪構件82及滑動構件90在第一軸向方向D21上朝向鏈輪支撐主體28偏置。此使第一棘輪齒80A與第二棘輪齒82A嚙合。

此外,如圖48中所見,當踩踏扭矩T1在傳動旋轉方向D11上輸入至鏈輪支撐主體28時,螺旋內部花鍵齒80H1在第一軸向方向D21上由螺旋外部花鍵齒46相對於鏈輪支撐主體28導引。此強有力地使第一棘輪齒80A與第二棘輪齒82A嚙合。在此狀態下,踩踏扭矩T1經由第一棘輪構件80及第二棘輪構件82(圖44)自鏈輪支撐主體28傳遞至輪轂主體36(圖44)。

如圖48中所見,在惰轉期間,藉由偏置構件84(圖44)與第一棘輪構件80之間產生之旋轉摩擦力F6,第一棘輪構件80與導引部分28G接觸以自第二棘輪構件82脫嚙。如圖49中所見,惰轉扭矩T2在惰轉期間在傳動旋轉方向D11上施加至輪轂主體36。惰轉扭矩T2經由第二棘輪構件82(圖44)自輪轂主體36(圖44)傳遞至第一棘輪構件80。此時,由螺旋外部花鍵齒46在第二軸向方向D22上相對於鏈輪支撐主體28導引螺旋內部花鍵齒80H1。此使第一棘輪構件80在第二軸向方向D22上抵抗偏置力F5相對於
鏈輪支撐主體28移動。因此,第一棘輪構件80在第二軸向方向D22上移動遠離第二棘輪構件82,從而致使第一棘輪齒80A與第二棘輪齒82A之間的嚙合較弱。此允許第二棘輪構件82在傳動旋轉方向D11上相對於第一棘輪構件80旋轉,從而防止惰轉扭矩T2經由第一棘輪構件80及第二棘輪構件82自輪轂主體36傳遞至鏈輪支撐主體28。此時,第一棘輪齒80A在圓周方向D1上與第二棘輪齒82A一起滑動。

如本文所使用之術語「包含」及其派生詞意欲為指定陳述特徵、元 件、組件、群組、整數及/或步驟的存在但不排除其他未陳述特徵、元件、組件、群組、整數及/或步驟的存在的開放術語。此概念亦適用於類似含義之詞語,例如術語「具有」、「包括」及其派生詞。 As used herein, the term "comprises" and its derivatives are intended to designate stated features, elements The presence of elements, components, groups, integers and/or steps is not excluded but other open terms do not state the presence of features, elements, components, groups, integers and/or steps. This concept also applies to words of similar meaning, such as the terms "having", "including" and their derivatives.
術語「構件」、「區段」、「部分」、「部件」、「元件」、「主體」及「結構」在以單數形式使用時可具有單一部件或複數個部件之雙重含義。 The terms "member", "section", "portion", "part", "element", "body" and "structure" when used in the singular can have the dual meaning of a single part or a plurality of parts.
諸如本申請案中敍述的「第一」及「第二」之序數數目僅為標識符,而不具有任何其他含義,例如特定次序等等。此外,舉例而言,術語「第一元件」自身不暗示「第二元件」之存在,且術語「第二元件」自身不暗示「第一元件」之存在。 The ordinal numbers such as "first" and "second" described in this application are only identifiers and do not have any other meaning, such as a specific order or the like. Furthermore, for example, the term "first element" does not imply the existence of a "second element" by itself, and the term "second element" does not imply the existence of a "first element" by itself.
如本文中所使用之術語「對」可涵蓋除其中成對元件具有彼此相同之形狀或結構之構形外之其中成對元件具有彼此不同的形狀或結構之構形。 The term "pair" as used herein may encompass configurations in which paired elements have different shapes or structures from each other, in addition to configurations in which paired elements have the same shape or structure as each other.
因此,術語「一」、「一或多個」與「至少一個」在本文中可互換地使用。 Accordingly, the terms "a", "one or more" and "at least one" are used interchangeably herein.
最後,如本文中所使用之諸如「大體上」、「大約」及「大致」之程度術語意謂所修飾之術語之合理量之偏差以使得最終結果並無顯著改變。本申請案中所描述之所有數值可被理解為包括諸如「大體上」、「大約」及「大致」之術語。 Finally, terms of degree such as "substantially", "approximately" and "approximately" as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. All numerical values described in this application can be understood to include terms such as "substantially", "approximately" and "approximately".
顯然,根據以上教示,本發明之眾多修改及變化為可能的。因此應理解,在所附申請專利範圍之範疇內,可以不同於如本文特定描述之方式的其他方式實踐本發明。 Obviously many modifications and variations of the present invention are possible in light of the above teachings.
