The first bracket 32a and the second bracket 32b are substantially the same shape in the first embodiment, and the first bracket 32a and the second bracket 32b are independent and separate parts from each other.
[0067] The at least one connecting portion 34 comprises a first connecting portion 34a provided on the first bracket 32a and a second connecting portion 34b provided on the second bracket 32b. The first connecting portion 34a and the second connecting portion 34b are each formed in a semicircular shape. The first connecting portion 34a comprises a first groove 34c that engages the connected portion 22c, and the second connecting portion 34b comprises a second groove 34d that engages the connected portion 22c. The first groove 34c and the second groove 34d comprise a straight portion and an arcuate portion that engage the outer peripheral surface of the connected portion 22c (refer to
[0068] The first connecting portion 34a and the second connecting portion 34b are connected to the bicycle component 22 in a state in which the bicycle component 22 is disposed between the first bracket 32a and the second bracket 32b. Specifically, the first connecting portion 34a and the second connecting portion 34b are connected to the connected portion 22c of the bicycle component 22.
[0069] The first bracket 32a comprises a first abutting portion 42. The second bracket 32b comprises a second abutting portion 44. The first abutting portion 42 abuts the second abutting portion 44 in a state in which the bicycle component 22 is fixed to the cylindrical portion 12b.
[0070] In the first embodiment, the first abutting portion 42 is provided on the first connecting portion 34a of the first bracket 32a, and the second abutting portion 44 is provided on the second connecting portion 34b of the second bracket 32b. The first abutting portion 42 comprises a pair of first abutting surfaces 42a, a second abutting surface 42b and a third abutting surface 42c. The second abutting surface 42b is disposed adjacent to one of the first abutting surfaces 42a, and is formed more recessed in the circumferential direction than the first abutting surface 42a. The third abutting surface 42c is disposed adjacent to the other first abutting surface 42a. The third abutting surface 42c is formed more protruding in the circumferential direction than the first abutting surface 42a. A step is formed between one of the first abutting surfaces 42a and the second abutting surface 42b, and between the other first abutting surface 42a and the third abutting surface 42c.
[0071] The second abutting portion 44 comprises a pair of fourth abutting surfaces 44a, a fifth abutting surface 44b and a sixth abutting surface 44c. The fifth abutting surface 44b is disposed adjacent to one of the fourth abutting surfaces 44a. The fifth abutting surface 44b is formed more protruding in the circumferential direction than the fourth abutting surface 44a. The sixth abutting surface 44c is disposed adjacent to the other fourth abutting surface 44a. The sixth abutting surface 44c is formed more recessed in the circumferential direction than the fourth abutting surface 44a. A step is formed between one of the fourth abutting surfaces 44a and the fifth abutting surface 44b, and between the other fourth abutting surface 44a and the sixth abutting surface 44c. As described above, by configuring the first abutting portion 42 and the second abutting portion 44, when the first connecting portion 34a is abutted to the second connecting portion 34b, the first connecting portion 34a and the second connecting portion 34b are arranged along the central axis CL. Accordingly, it becomes easy to position the first bracket 32a and the second bracket 32b. Furthermore, the first bracket 32a and the second bracket 32b can be formed in substantially the same shape.
[0072] The at least one fixing portion 36 comprises a first fixing portion 36a provided on the first bracket 32a and a second fixing portion 36b provided on the second bracket 32b. The first fixing portion 36a and the second fixing portion 36b are plate-shaped members. Each of the first fixing portion 36a and the second fixing portion 36b is curved in an arcuate shape centered on the central axis CL. The first fixing portion 36a comprises a first inner surface 38a and a first outer surface 40a. The first inner surface 38a faces the outer peripheral surface 12h of the cylindrical portion 12b. The a first outer surface 40a faces in the direction opposite from the first inner surface 38a. The second fixing portion 36b comprises a second inner surface 38b and a second outer surface 40b. The second inner surface 38b faces the outer peripheral surface 12h of the cylindrical portion 12b. The second outer surface 40b faces in the direction opposite from the second inner surface 38b. The first fixing portion 36a and the second fixing portion 36b are arranged opposing each other in the radial direction that is perpendicular to the direction in which the central axis CL extends. The maximum distance between the first inner surface 38a and the first outer surface 40a in the radial direction that is perpendicular to the direction in which the central axis CL of the cylindrical portion 12b extends, that is the thickness of the first fixing portion 36a, is less than or equal to 5 millimeters. The maximum distance between the first inner surface 38a and the first outer surface 40a in the radial direction that is perpendicular to the direction in which the central axis CL of the cylindrical portion 12b extends is preferably less than or equal to 2 millimeters, and more preferably greater than or equal to 0.5 millimeters and less than or equal to 2 millimeters. Similarly, the maximum distance between the second inner surface 38b and the second outer surface 40b in the radial direction that is perpendicular to the direction in which the central axis CL of the cylindrical portion 12b extends, that is, the thickness of the second fixing portion 36b, is less than or equal to 5 millimeters. The maximum distance between the second inner surface 38b and the second outer surface 40b in the radial direction that is perpendicular to the direction in which the central axis CL of the cylindrical portion 12b extends is preferably less than or equal to 2 millimeters, and more preferably greater than or equal to 0.5 millimeters and less than or equal to 2 millimeters. The first fixing portion 36a and the second fixing portion 36b are fixed to the outer peripheral surface 12h of the cylindrical portion 12b by a pressing force that acts on the first outer surface 40a and the second outer surface 40b. This pressing force is, for example, generated by winding bar tape 50, as a strip-shaped tape member that has stretchability that can be wound onto the handlebar 12c, onto the at least one outer surface 40 of the at least one fixing portion 36. Accordingly, since normally, the bicycle component 22 can be fixed to the cylindrical portion 12b by using bar tape 50 that is wound to the outer peripheral surface of the handlebar 12c, the bicycle component 22 can be easily fixed. Further, it is possible to easily generate a pressing force by only winding the bar tape 50 on at least one outer surface 40 of the fixing portion 36.
Bicycle Component Assembly Fixing Procedure
[0073] When fixing the bicycle component 22 to the cylindrical portion 12b of the bicycle in the state shown in
[0074] Here, the bicycle component 22 can be detachably attached to the cylindrical portion 12b without using a tool. The workability of an operation to fix the bicycle component 22 can thereby be improved, and it is possible to provide a bicycle component fixing structure 24 and a bicycle component assembly 20 that is detachable with respect to the cylindrical portion 12b. The first bracket 32a and the second bracket 32b can be connected to the bicycle component 22 in a state in which a part of the component body 22a of the bicycle component 22 is inserted in the cylindrical portion 12b, after connecting, for example, the electrical wires L2, L3 and L4 to the communication unit 28b of the bicycle component 22 in advance.
