Abstract
A clutch unit of a bicycle derailleur includes a main body, a cover for the main body, a positioning assembly, and a pressure-applying assembly. Both assemblies are received in a space between the main body and the cover. The main body has a top side with a receiving groove and is pivotally connected with a rotating shaft, which extends out of a bottom portion of the receiving groove. The positioning assembly includes a ratchet, a pawl, and an elastic member. The ratchet is pivotally connected in the receiving groove, can rotate with the rotating shaft, and has ratchet teeth annularly arranged at an equal spacing. The pawl is adjacent to and can move toward and away from the ratchet, has a meshing tooth for meshing with the corresponding ratchet tooth, and is elastically biased toward the ratchet by the elastic member. The pressure-applying assembly applies resistance to the ratchet.
