ABSTRACT:
A hub clutch device for a bicycle includes a threaded shaft, a hub, a positioning sleeve, a movable sleeve, an elastic member, a fixing seat, and a plurality of urging balls. Thus, each of the urging balls is moved between a respective one of the adjusting slots of the movable sleeve and a respective one of the adjusting slots of the fixing seat to detach the fixing seat and the movable sleeve from the positioning sleeve, so that when the positioning sleeve and the hub are rotated, the fixing seat is not rotated, so that the freewheel will not be rotated by the wheel when the pedal stops operating.
