The sliding device includes a retaining portion and a rolling portion. The rolling portion includes a first combining portion, a second combining portion, a wheel shaft and a contact unit. The contact unit is clampingly and sandwichedly disposed between the first and second combining portion. Of the wheel shaft; and the wheel shaft is rotatably engaged with the retaining seat and is received in the first combining portion.
