ABSTRACT:
To prevent the detachment of the front wheel of a bicycle from the front fork formed of a pair of laterally spaced fork arms each having a free end with an open ended slot arranged to receive the hub spindle of the front wheel which is secured to the front fork by washers and hub nuts, the slot is shaped to have at least one portion which is positioned at the place occupied by the hub spindle when it is assembled within the front fork, that is, at the back of the slot, and which is wider than the diameter of the hub spindle and the washer is provided with a hole arranged to receive the hub spindle therein and at least one projection extending from one of its faces along the periphery of the hole. The projections are fitted into the widened portions of the slots so that even though the nuts securing the front wheel to the front fork become loose, the projections of the washers are retained in the corresponding slots in the front fork preventing the detachment of the front wheel.
