Then, the other end (4) of first fitting body (2) and the other end (7) of the second fitting body (5) engaging with the recesses and protrusions of a fluted portion of a sensor portion (28) are fixed with a fixing screw (42). Thus, the other end (4) of the first fitting body (2) and the other end (7) of the second fitting body (5) are drawn near to each other, and a fitting for a bicycle (1) is firmly fixed to fork (34). |
