如圖15及圖16中所見，限制部分50經構形以在附接狀態中限制第一附接部分34及第二附接部分36之至少一者在第一方向D2、第二方向D5及第三方向D6之至少一者上相對於鏈條導引件14移動。在本實施例中，限制部分50經構形以在附接狀態中限制第一附接部分34及第二附接部分36之各者在第一方向D2、第二方向D5及第三方向D6之各者上相對於鏈條導引件14移動。然而，視需要及/或視情況，限制部分50可經構形以在附接狀態中限制第一附接部分34及第二附接部分36之至少一者在第一方向D2、第二方向D5及第三方向D6之至少一者上相對於鏈條導引件14移動。As seen in FIGS. 15 and 16 , the limiting portion 50 is configured to limit at least one of the first attachment portion 34 and the second attachment portion 36 from moving relative to the chain guide 14 in at least one of the first direction D2, the second direction D5, and the third direction D6 in the attached state. In the present embodiment, the limiting portion 50 is configured to limit each of the first attachment portion 34 and the second attachment portion 36 from moving relative to the chain guide 14 in each of the first direction D2, the second direction D5, and the third direction D6 in the attached state. However, as needed and/or as circumstances dictate, the limiting portion 50 may be configured to limit at least one of the first attachment portion 34 and the second attachment portion 36 from moving relative to the chain guide 14 in at least one of the first direction D2, the second direction D5, and the third direction D6 in the attached state.

如圖15中所見，在附接狀態中，第一限制部分52可在第二方向D5上與鏈條導引附接件30 (例如，第一導板16)接觸以限制鏈條導引附接件30在第二方向D5上相對於鏈條導引件14移動。在附接狀態中，第一限制部分52可在第二方向D5上與鏈條導引件14 (例如，第一導板16)接觸以限制鏈條導引附接件30在***方向D31上相對於鏈條導引件14移動。在附接狀態中，第一限制部分52可在第一方向D2上與鏈條導引件14 (例如，第二導板18)接觸以限制鏈條導引附接件30在第一方向D2上相對於鏈條導引件14移動。15 , in the attached state, the first limiting portion 52 may contact the chain guide attachment 30 (e.g., the first guide plate 16) in the second direction D5 to limit the chain guide attachment 30 from moving relative to the chain guide 14 in the second direction D5. In the attached state, the first limiting portion 52 may contact the chain guide 14 (e.g., the first guide plate 16) in the second direction D5 to limit the chain guide attachment 30 from moving relative to the chain guide 14 in the insertion direction D31. In the attached state, the first limiting portion 52 may contact the chain guide 14 (e.g., the second guide plate 18) in the first direction D2 to limit the chain guide attachment 30 from moving relative to the chain guide 14 in the first direction D2.

在附接狀態中，第二限制部分54可在第二方向D5上與鏈條導引件14 (例如，第二導板18)接觸以限制鏈條導引件14在第二方向D5上相對於鏈條導引件14移動。In the attached state, the second limiting portion 54 may contact the chain guide 14 (eg, the second guide plate 18) in the second direction D5 to limit movement of the chain guide 14 relative to the chain guide 14 in the second direction D5.

如圖16中所見，在附接狀態中，第三限制部分56可在第一方向D2上與鏈條導引件14 (例如，第一導板16及第二導板18之至少一者)接觸以限制鏈條導引附接件30在第一方向D2上相對於鏈條導引件14移動。在附接狀態中，第三限制部分56可在第三方向D6上與鏈條導引件14 (例如，第二導板18)接觸以限制鏈條導引附接件30在第三方向D6上相對於鏈條導引件14移動。16, in the attached state, the third limiting portion 56 may contact the chain guide 14 (e.g., at least one of the first guide plate 16 and the second guide plate 18) in the first direction D2 to limit the chain guide attachment 30 from moving relative to the chain guide 14 in the first direction D2. In the attached state, the third limiting portion 56 may contact the chain guide 14 (e.g., the second guide plate 18) in the third direction D6 to limit the chain guide attachment 30 from moving relative to the chain guide 14 in the third direction D6.

在附接狀態中，第四限制部分58可在第三方向D6上與鏈條導引件14 (例如，第二導板18)接觸以限制鏈條導引附接件30在第三方向D6上相對於鏈條導引件14移動。In the attached state, the fourth limiting portion 58 may contact the chain guide 14 (eg, the second guide plate 18) in the third direction D6 to limit movement of the chain guide attachment 30 relative to the chain guide 14 in the third direction D6.

如圖4中所見，鏈條導引附接件30在***方向D31上***至鏈條導引空間14S中。如圖17中所見，當鏈條導引附接件30***至鏈條導引空間14S中時，鏈條導引附接件30經變形以使外長度L1更短。例如，外長度L1之最小長度比在第一方向D2上界定於第一導板16與第二導板18之間的距離DS3長。因此，在其中鏈條導引附接件30相對於第一方向D2傾斜之一狀態中，鏈條導引附接件30***至鏈條導引空間14S中。As seen in FIG. 4 , the chain guide attachment 30 is inserted into the chain guide space 14S in the insertion direction D31. As seen in FIG. 17 , when the chain guide attachment 30 is inserted into the chain guide space 14S, the chain guide attachment 30 is deformed to make the outer length L1 shorter. For example, the minimum length of the outer length L1 is longer than the distance DS3 defined between the first guide plate 16 and the second guide plate 18 in the first direction D2. Therefore, in a state in which the chain guide attachment 30 is tilted relative to the first direction D2, the chain guide attachment 30 is inserted into the chain guide space 14S.

如圖18中所見，在其中鏈條導引附接件30設置於鏈條導引空間14S中且變形之一狀態中，第二突出部分36C***至第二開口14B中。如圖10中所見，在其中第二突出部分36C設置於第二開口14B中之一狀態中，第一突出部分34C***至第一開口14A中。此時，如圖11及圖12中所見，當第一突出部分34C***至第一開口14A中時，緊固件19A之頭部分19A2及緊固件19B之頭部分19B2配置於開口30P中。As seen in Fig. 18, in a state where the chain guide attachment 30 is disposed in the chain guide space 14S and deformed, the second protrusion 36C is inserted into the second opening 14B. As seen in Fig. 10, in a state where the second protrusion 36C is disposed in the second opening 14B, the first protrusion 34C is inserted into the first opening 14A. At this time, as seen in Figs. 11 and 12, when the first protrusion 34C is inserted into the first opening 14A, the head portion 19A2 of the fastener 19A and the head portion 19B2 of the fastener 19B are disposed in the opening 30P.

在本申請案中，如本文中使用之術語「包括」及其衍生詞旨在作為開放性術語，其等指定存在陳述特徵、元件、組件、群組、整數及/或步驟，但不排除存在其他未陳述特徵、元件、組件、群組、整數及/或步驟。此概念亦適用於類似意義之字詞，舉例而言，術語「具有」、「包含」及其等之衍生詞。In this application, the term "include" and its derivatives as used herein are intended to be open terms, which specify the existence of stated features, elements, components, groups, integers and/or steps, but do not exclude the existence of other unstated features, elements, components, groups, integers and/or steps. This concept also applies to words with similar meanings, for example, the terms "have", "include" and their derivatives.

術語「部件」、「區段」、「部分」、「零件」、「元件」、「本體」及「結構」在以單數使用時可具有一單個零件或複數個零件之雙重意義。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.

諸如本申請案中所敘述之「第一」及「第二」之序數僅係識別符，而不具有任何其他意義(舉例而言，一特定順序及類似者)。此外，舉例而言，術語「第一元件」本身不暗示存在「第二元件」，且術語「第二元件」本身不暗示存在「第一元件」。As described in this application, the ordinal numbers "first" and "second" are merely identifiers and do not have any other meanings (e.g., a specific order and the like). In addition, for example, the term "first element" itself does not imply the existence of a "second element", and the term "second element" itself does not imply the existence of a "first element".

除了其中元件對具有彼此相同之形狀或結構之構形以外，如本文所使用之術語「對」亦可涵蓋其中元件對具有彼此不同之形狀或結構之構形。In addition to a configuration in which a pair of elements have the same shape or structure as each other, the term "pair" as used herein may also encompass a configuration in which a pair of elements have different shapes or structures from each other.

術語「一(或一個)」、「一或多個」及「至少一個」可在本文中互換使用。The terms "a", "one or more" and "at least one" may be used interchangeably herein.

如本發明中使用之片語「…之至少一者」意謂一所要選擇之「一或多者」。對於一項實例，如本發明中使用之片語「…之至少一者」在其選擇之數目係兩個之情況下意謂「僅一單個選擇」或「兩個選擇之兩者」。對於其他實例，如本發明中使用之片語「…之至少一者」在其選擇之數目等於或超過三個之情況下意謂「僅一單個選擇」或「等於或超過兩個選擇之任何組合」。例如，片語「A及B之至少一者」涵蓋(1)僅A、(2)僅B，及(3) A及B兩者。片語「A、B及C之至少一者」涵蓋(1)僅A、(2)僅B、(3)僅C，(4) A及B兩者、(5) B及C兩者、(6) A及C兩者，及(7)全部A、B及C。換言之，在本發明中，片語「A及B之至少一者」並不意謂「A之至少一者及B之至少一者」。As used in the present invention, the phrase "at least one of..." means "one or more" of a desired choice. For one example, the phrase "at least one of..." as used in the present invention means "only a single choice" or "two of the two choices" when the number of the choices is two. For other examples, the phrase "at least one of..." as used in the present invention means "only a single choice" or "any combination of equal to or more than two choices" when the number of the choices is equal to or more than three. For example, the phrase "at least one of A and B" covers (1) only A, (2) only B, and (3) both A and B. The phrase "at least one of A, B, and C" covers (1) only A, (2) only B, (3) only C, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all of A, B, and C. In other words, in the present invention, the phrase "at least one of A and B" does not mean "at least one of A and at least one of B."

最後，如本文中使用之諸如「實質上」、「大約」及「近似」之程度術語意指修飾術語之一合理偏差量，使得最終結果未顯著改變。本申請案中所描述之所有數值可被解釋為包含諸如「實質上」、「大約」及「近似」之術語。Finally, as used herein, terms of degree such as "substantially", "approximately" and "approximately" mean a reasonable deviation of the modified term so that the end result is not significantly changed. All numerical values described in this application may be interpreted as including terms such as "substantially", "approximately" and "approximately".

顯然，依據以上教示本發明之許多修改及變動係可能的。因此，應理解，在隨附發明申請專利範圍之範疇內，可依除本文中具體描述之方式外之方式實踐本發明。Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present invention may be practiced in ways other than those specifically described herein.
