A castor includes a castor body, an operation unit connected with the castor body, a locking unit connected with the castor body, a roller mounted on the castor body, and a mandrel extended through the castor body and the roller. Thus, when the castor is locked completely, the roller is entirely locked by the locking unit so that the roller cannot roll and translate and cannot be turned around simultaneously so as to provide a double-braking effect. In addition, when the castor is locked partially, the roller is partially locked by the locking unit so that the roller cannot be turned around but can roll and translate freely.
