ABSTRACT:
A quick release apparatus for a bicycle for pulling and fixing a drawbar having a cam follower formed at one end thereof. The apparatus includes a housing for contacting a bicycle frame, and a rotary cam supported in the housing to be rotatable about an axis substantially perpendicular to the drawbar. The rotary cam is rotatable by a cam lever to contact the cam follower to pull the drawbar toward the housing. The rotary cam and cam lever are interconnected through a coupling device disposed at one side of the housing. The coupling device includes a first coupling for restraining a relative rotation between the rotary cam and the cam lever, and a second coupling for restraining a relative movement in a direction of the axis between the rotary cam and the cam lever.
