Abstract
Wheel structure for a trash container comprising an enhanced thickness hub portion defined by positioning a metal member within the locus of the wheel wall during molding so as to increase wall thickness by better heat transfer and increase resin buildup in the vicinity of the metal member. The metal member is usefully a fastener for the end of the wheel carrying axle whereby the position of the wheel on the axle is fixed by the fastening metal member being trapped in the increased wall thickness hub.
