For rotating a wheel 20, this device is provided with a unit supported by a support bracket 30 connecting with the fixed bed 10 in a method of rotating it about a horizontal shaft A getting across the workstation P. This unit is provided with a mandrill 32 having a motor of which the shaft B is vertical to, cross with, or substantially cross with the rotating shaft A to tightly lock a wheel rim, so that the rotating shaft A of the support bracket 30 can get across a substantially center position of the tire of the wheel 20 supported by the mandrill 32.
