A two-purpose roller skate, includes a shoe body (1) and a pair of wheel assemblies (2,2'), each of the wheel assemblies includes a base (21), the base (21) having an installation plate (211) and two parallel side walls (212,212') extending downwards from the installation plate (211), a swing arm (22) being mounted in a hinging way on a pivot (23), and on at least one side of the said swing arm (22) there are formed the first protruding shoulders (222,222') and the second protruding shoulders (223,223') which can be engaged with the lower end face (214) and the back end face (215) of the base (21) respectively. A stopping mechanism locks said swing arm (22) on the first position and the second position being at an angle alpha to each other. The swing arm can provide a firm support for the lower end face of the base to improve the overall rigidity of the wheel assembly.
