Abstract
A locking nut assembly comprises an axle nut, a resilient ring member and a cover member. The axle nut has a threaded bore at one end and a locking bore at the other end thereof. The threaded bore has a structural configuration which threadingly engages a bicycle axle. The outer surface of the axle nut has flat surface areas and an annular groove. The resilient ring member is disposed within the annular groove. The cover member is slidingly disposed over the outer surface of the axle nut. The cover member has a tapered, smooth outer surface and an end portion with a bore opening juxtaposed the locking bore of the axle nut. The use of the assembly prevents the untightening of the axle nut which holds the bicycle wheel in place on the bicycle frame.
