A structure for supporting a wheel of a roller skate which enables a wheel coupled to an outsole of a roller skate to be supported and retracted simply and reliably is disclosed. The structure includes a frame attached to an outsole of the roller skate, which has at its bottom wall recesses and protrusions; a swing plate pivotally coupled to the frame, which has a central hole; and a bracket for rotatably supporting a wheel, which has a throughhole and a top portion to be releasably fitted in the pair of fitting recesses of the frame, and which is rotatably coupled to the swing plate by a bolt threaded in the hole of the swing plate through the throughhole of the bracket. The bracket has a pair of arms extending downward which rotatably support the wheel therebetween, and a protrusion formed at the top portion thereof which is releasably fitted in the fitting recesses of the frame. The throughhole of the bracket is formed with a concentric counterbored portion receiving a coil spring therein.
