[0119] In this embodiment, the limiting opening 46 includes a limiting hole 46A. The limiting hole 46A includes a closed end and does not include a through hole. However, the limiting opening 46 is not limited to the structure described above.

However, if needed and / or desired, one of the limiting member 44 and the limiting opening 46 can be configured to limit only one of the first and second rotations of the bracket body 14 in the bracket-mounted state.

[0131] The derailleur attachment 22 is spaced apart from the frame attachment 20. The component attachment 24 is spaced apart from both the frame attachment 20 and the derailleur attachment 22.

[0132] One of the derailleur attachment portion 22 and the component attachment portion 24 is disposed on the opposite side of the other of the derailleur attachment portion 22 and the component attachment portion 24 relative to the frame attachment portion 20. One of the derailleur attachment portion 22 and the component attachment portion 24 is disposed on the opposite side of the other of the derailleur attachment portion 22 and the component attachment portion 24 relative to the frame attachment portion 20 in the arrangement direction D3.

The frame attachment 20 is also integrally configured as a single, one-piece component with at least one of the derailleur attachment 22 and the component attachment 24. However, if desired and / or as desired, the frame attachment 20 may be a separate component from at least one of the derailleur attachment 22 and the component attachment 24. For example, the frame attachment 20 may be integrally configured as a single, one-piece component with one of the derailleur attachment 22 and the component attachment 24, while simultaneously being a separate component from the other of the derailleur attachment 22 and the component attachment 24.

[0202] In this application, the term "comprising" and its derivatives as used herein are intended to be open-ended terms that specify the presence of the stated features, elements, components, groups, integers, and / or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers, and / or steps. This concept also applies to words with similar meanings, such as the terms "having," "comprising," and their derivatives.

[0203] When used in the singular, the terms “component,” “section,” “part,” “section,” “element,” “body,” and “structure” can have a dual meaning of a single part or multiple parts.

[0204] The ordinal numbers such as "first" and "second" used in this application are merely identifiers and have no other meaning, such as a specific order. Furthermore, for example, the term "first element" does not imply the existence of a "second element," nor does the term "second element" imply the existence of a "first element."

[0205] As used herein, the term "pair" includes not only a pair of elements having the same shape or structure as each other, but also a pair of elements having different shapes or structures.

[0206] The terms “a” (or “one”), “one or more” and “at least one” are used interchangeably in this document.

[0207] As used in this disclosure, the phrase "at least one" means "one or more" of the desired choices. For example, the phrase "at least one" as used in this disclosure means "only one single choice" or "two of two choices" if the number of choices is two. As another example, the phrase "at least one" as used in this disclosure means "only one single choice" or "any combination equal to or more than two choices" if the number of choices is equal to or more than three. For example, the phrase "at least one of A and B" includes (1) A alone, (2) B alone, and (3) both A and B. The phrase "at least one of A, B, and C" includes (1) A alone, (2) B alone, (3) C alone, (4) A and B, (5) B and C, (6) A and C, and (7) all of A, B, and C. In other words, in this disclosure, the phrase "at least one of A and B" does not mean "at least one A and at least one B".

[0208] Finally, degree terms such as “substantially,” “about,” and “approximately,” as used herein, indicate reasonable deviations from the original terminology such that the final result is not significantly altered. All numerical values ​​described in this application can be interpreted as including terms such as “substantially,” “about,” and “approximately.”

[0209] Obviously, many variations and modifications of the invention are possible based on the above teachings. Therefore, it should be understood that the invention can be practiced in ways other than those specifically described herein, within the scope of the appended claims.
