ABSTRACT:
A wheel assembly for a baby carriage is provided comprising two wheels mounted on opposing ends of a shaft supported by a shaft holder fixed at an end of a supporting rod of a baby carriage. The shaft is coupled to the two wheels and a combining disc is secured to the shaft by small projections inserted within an annular groove formed in the shaft. A cap covers a recessed aperture of each wheel and is pressed inwardly to compress the combining disc for disengagement of the combining disc from the shaft and the wheel from the shaft.
