A wheel assembly has a support unit, a rotating unit and an arresting unit. The support unit includes a sleeve, a stop hole and a recess. Brackets respectively extend from opposing sides of the sleeve. A rotating shaft pivots the wheel between the brackets. The rotating unit includes a base. An axis portion extends from a surface of the base for movably engaging with the sleeve. A tooth-like surface is formed on a side of the axis portion. The arresting unit includes a limiting portion movably pivoted between the brackets and in the vicinity of the wheel. A pressing plate pivots to an end of the limiting portion movably. A link portion movably links the limiting portion and the pressing plate and forms an abutting portion. The limiting portion forms a stop portion thereon. The arresting unit limits movement and rotation directions of the support unit and the wheel simultaneously.
