A wheel-supporting hanger for utilization on the frame of a roller skate, this hanger having an upper mounting portion as well as front and back portions. A central cavity is defined in the front portion of the hanger, in which an axle-receiving member is operatively mounted in a cantilever manner. A wheel-supporting axle protrudes outwardly in a cantilever manner from the axle-receiving member, with a screw utilized on the outer end of the axle for retaining a skate wheel in an operative manner on the axle. A structural member is located in an upper part of the cavity, defining a substantially flat undersurface in a relatively closely spaced relationship to the axle-receiving member. The cantileverly mounted axle-receiving member, because of the mounting of the axle therein, is permitted to flex upwardly as well as to move laterally to a controlled extent should the wheel mounted on the axle encounter an obstacle or obstruction. The axle-receiving member, in the instance of lateral movement, moves a commensurate distance with respect to the substantially flat undersurface, with this movement lessening the chance of material stress to the skate as a result of the shock of the skate wheel striking the obstacle. I prefer to utilize an insert of resilient, shock absorbing material between the axle-receiving member and the flat undersurface, with this insert being of selectable hardness so that the degree of permissible vertical travel of the axle can be closely controlled.
