ABSTRACT:
A wheel assembly includes a main body, two wheels, two positioning shafts, and two retaining rods. In practice, the retaining portion of each of the retaining rods is urged on the positioning plates of the respective positioning shaft to position the locking portion of each of the positioning plates on the inner side the respective pivot hole of the main body so as to lock each of the two positioning shafts on the main body, so that each of the two wheels is attached on the main body rigidly and stably, thereby preventing the two wheels from detaching from the main body during a long-term utilization.
