Abstract
A wheel hub for a bicycle includes a hub shell with an inner wall segment within which an engaging portion of a driven cylinder is non-rotatably fitted from one end of the hub shell. A screw-threaded cylinder can enter the hub shell from the other end, and has an externally threaded shank to engage threadedly an internally threaded portion of the engaging portion, and an enlarged head which is provided with a resilient member to restrain rotatably the head relative to another inner wall segment of the hub shell during the threaded engagement. As such, the screw-threaded cylinder can be remained in the hub shell even after the driven cylinder is removed from the hub shell to prevent misplacement of the screw-threaded cylinder.
