In a roll changing apparatus of a rolling mill, a stationary roll changing table is provided on a front surface of a work side of the rolling mill. Pull-out rails and upwardly and downwardly movable shift rails are provided on the roll changing table. Shift blocks are provided for detachably attaching to a work roll assembly which has been pulled out, to move the work roll assembly sideways in a shifting direction. Only the work roll assembly to be pulled out can be shifted easily, and replaced with a new work roll assembly without the use of an elaborate foundation structure. Thus, work rolls can be changed swiftly.
