<p>A derailleur that can provide a speed-change operation while performing a braking operation and which can provide an optimum speed-change operation for various running conditions. Namely, provided on the outer circumference of a gripping portion of a handle bar (3) are a first speed-change operating body (14) and a second spedd-change operating body (103) that are supported such that they can be rotated around the axis of the handle bar, a cable winding body (107) adapted to be rotated by rotation of these speed-change operating bodies so as to pull in or pay out a speed-change operating cable, and a locking mechanism (15) for locking the cable winding body at a predetermined rotating position, the first speed-change operating body being connected to the cable winding body in such a manner that the cable winding body is integrally rotated in cable pulling-in and paying-out directions, while the second speed-change operating body being connected to the cable winding body via a transmission mechanism (127) for rotating the cable winding body in the cable pulling-in or paying-out direction through reciprocating rotating operations from a predetermined rotation starting point.</p> |
