Abstract
A quick release device includes a tightening bar having an enlarged head and an actuated end outboard of two fork blades of a bicycle, and a cam member having front and rear ends, and a cam segment interposed therebetween and engaging a cam follower surface of the actuated end such that rotation of the cam segment results in movement of the actuated end between tightening and loosening positions relative to one of the fork blades. A cover includes front and rear walls which defines an accommodation space therebetween for receiving the actuated end and the cam segment. The front and rear ends extend outwardly of the front and rear walls, respectively. A lever includes front and rear lug portions which are coupled respectively with the front and rear ends of the cam member to enable the cam segment to be rotated by a turning movement of the lever.
