In this embodiment, the axial projection 382 to the first outer connecting plate 14 fastened. The axial projection 582 is attached to the second outer connecting plate 16 fastened. The axial projection 582 It essentially has the same structure as the axial projection 382 However, the axial projection can 582 a structure different from that of the axial projection 382 exhibit.

[0155] The at least one axial projection 382 and / or 582 It contains a plastic or resin material. It has at least one axial projection. 382 and / or 582 is connected to at least one of the first intermediate section 26 and the second intermediate section 36 It is attached via an adhesive and integral forming process. In this embodiment, the axial projection 582to the second intermediate section 36 via adhesive 583 fastened. In a case where the axial projection 582 to the second intermediate section 36 via integral form method, as in Fig. 27 can be seen, is / will be attached, the axial projection 582 to the second intermediate section 36 It is attached via an insertion molding process. In such an embodiment, the axial projection covers 582 the second intermediate section 36 ab. In a case where the second outer connecting plate 16 a plastic material or resin material, the second outer connecting plate can 16 and the axial projection 582 integrally formed together via an integral forming process as a single unit element.

[0156] The at least one axial projection 382 and / or 582 includes the axial projection 382projecting from the first inner surface 76 in the axial direction D1.

[0157] Regarding the bicycle chain 512 Is it possible to add the following effects to and / or instead of the effects produced by the bicycle chain? 412 to be achieved according to the second embodiment.

[0158] Since the axial projection 382 If a plastic or resin material is included, the plastic or resin material may produce unusual noises caused by the interaction between the axial protrusion. 382 and caused by the chainring tooth B9 of the bicycle chainring B5 and / or B6, reduce.

[0159] Since the axial projection 582The plastic or resin material may contain unusual noises caused by the interaction between the axial projection. 582 and is caused by the chainring tooth B9 of the bicycle chainring B5 and / or B6, reduce.

[0160] The at least one axial projection 582 is connected to at least one of the first intermediate section 26 and the second intermediate section 36 via one of an adhesive 583 and integral forming process. Accordingly, it is possible to effectively control the axial projection. 582 including the metallic material attached to the first outer connecting plate 14 to fasten, taking into account mass production or mass manufacturing. The production efficiency of the bicycle chain. 512 is particularly improved if the axial protrusion 582 to the first intermediate section 26is / will be attached via integral forming process.

[0161] Furthermore, if the second outer connecting plate 16 free from at least one axial projection 382 and / or 582 Is it possible to increase the shifting performance of the bicycle chain? 512 between the multitude of bicycle chainrings B5 and B6 by the front derailleur B7 and / or the rear derailleur B8 to maintain.

[0163] In the present application, the term "attached" or "fastening," as used herein, encompasses configurations in which one element is directly attached to another by fixing the element directly to the other element; configurations in which the element is indirectly attached to the other element via an intermediate element or elements; and configurations in which one element is integral with another element, i.e., one element is essentially part of the other element. This concept can also be applied to words with similar meanings, such as "connected," "coupled," "mounted," "glued," "fixed," and their derivatives.

[0164] The term "comprehensive" and its derivatives, as used herein, are to be understood as open terms that specify the presence of the mentioned features, elements, components, groups, integers, and / or steps, but do not exclude the presence of unmentioned features, elements, components, groups, integers, and / or steps. This can also be applied to words with similar meanings, such as "exhibit," "include," and their derivatives.

[0165] The terms “link”, “section”, “section”, “part” and “element”, when used in the singular, can have the plural usage of a single part and a multitude of parts.

[0166] The designations such as "first" and "second," as used in the present application, are merely identifying marks and have no other meaning, such as indicating a specific order or the like. Furthermore, 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.

[0167] The term “a pair of”, as used herein, includes configurations in which the pair of elements have different shapes or structures from each other and additional configurations in which the pair of elements may have the same shape or structure from each other.

[0168] Finally, the magnitude terms such as "essentially", "by" and "approximately" as herein use a reasonable amount of deviation of the modified term so that the final result is not significantly altered.

[0169] Naturally, numerous modifications and variations of the present invention are possible in light of the foregoing teachings. It should therefore be understood that, within the scope of the appended claims, the invention may be practiced or exercised in ways other than those specifically described herein.
