A castor assembly includes a base, a wheel unit and a rotation shaft. The wheel unit is located under the base and includes a pivot member, an elastic member biased and exposed between the base and the pivot member, and two rollers mounted on the pivot member. The rotation shaft is mounted between the base and the wheel unit and extends through the elastic member. The rotation shaft has a periphery provided with an operation slot. A positioning pin extends through the pivot member and is slidable in the operation slot of the rotation shaft. Thus, the elastic member is exposed outward so that the user clearly sees the elastic member and knows the shock-absorbing function provided by the elastic member.
