Abstract

A derailleur of a bicycle includes a fixing portion, a chain guiding portion, a linkage portion, a movable portion and a pivot. The fixing portion is adapted to be fixed to a frame of the bicycle. The chain guiding portion is adapted to be linked up with a chain and guide the chain to a driving direction. The linkage portion is connected between the fixing portion and the chain guiding portion. The movable portion is pivotally to the linkage portion and the chain guiding portion, and the movable portion includes a pressing element, a base and a sprag clutch. The pressing element is disposed at a side of the movable portion away from the chain guiding portion. The base is connected to the chain guiding portion. The sprag clutch is disposed between the pressing element and the base. The pivot is connected to the movable portion and the chain guiding portion, and is rotatably through the pressing element, the sprag clutch and the base. The chain guiding portion is adapted to be rotated by the pivot relative to the movable portion in a first direction or a second direction. The sprag clutch is adapted to stop the pivot from rotating in the second direction, and makes the pivot drive the pivot to rotate in the second direction. The pressing element is adapted to press against the sprag clutch towards the base to restrain the pivot from rotating the chain guiding portion in the second direction.
