A mechanism, and refrigeration appliance containing a mechanism, for providing displacement of a shelf of a refrigeration appliance, which has at least one refrigeratable cabinet with a base and two side walls substantially perpendicular to the base. The mechanism has at least one supporting device associated to the side wall of the refrigeratable cabinet by a side bar having a longitudinal portion that is substantially parallel to the base. The association between the supporting device and the side bar is able to provide mechanical support to the shelf. The mechanism also comprises a pivoting arm provided with at least one first end which is connected articulatedly to the shelf and a second end connected articulatedly to the supporting device, which associates the shelf to the supporting device. The pivoting arm is able to move angularly so as to allow the displacement of the shelf in relation to the supporting device.
