Abstract: A vehicle wheel attaching device for removably attaching general-road traveling wheels to the hubs of a vehicle by utilizing an independent adapter in such a manner as to enable transmission of torque. The adapter is made approximately in the form of a top hat as a whole and is bent at its top to form a dish spring surface for contact with the head of a center bolt which is pre-fitted thereto so as to extend therethrough. A center nut is applied to the projecting front end of the bolt, the nut being tightened to cause elastic action of the top surface of the adapter, thereby fixing the wheel in position in a non-rigid condition.
