Abstract
A waterproof end cap for covering and closing an end hole of a bicycle head tube includes a threaded locking base, a locking member, and a sealing cover. The threaded locking base is engaged in the end hole. The locking member has large- and small-diameter portions. The end of the large-diameter portion that faces away from the small-diameter portion has an outwardly extending annular plate. The small-diameter portion is externally threaded, extends into the end hole, and threadedly connects with the threaded hole of the threaded locking to base such that the annular plate is pulled to cover the end hole. The sealing cover is larger than the annular plate in diameter and has opposite first and second sides. The first side is free of water-holding spaces. The second side covers the annular plate detachably through elastic engagement. Water can neither accumulate on nor leak through the sealing cover.
