Apparatus for the variable setting of the control times of gas exchange valves of an internal combustion engine

An apparatus for variable setting of control times of gas exchange valves of an internal combustion engine, comprising:

• a drive element brought into drive connection with a crankshaft of the internal combustion engine;
• an output element brought into drive connection with a camshaft of the internal combustion engine, the output element being arranged such that the output element is pivotable with respect to the drive element;
• and
• a side cover axially delimiting the output element and/or the drive element and being connected in a rotationally fixed manner to the drive element or the output element by at least one fastening element, the side cover having a sealing cover and at least one mating element, the sealing cover being composed at least partially of a metallic material and having at least one opening, and the fastening element reaching through the opening at least partially and interacting with the mating element in such a way that a rotationally fixed connection can be produced between the side cover and the output element or the drive element
• wherein the mating element is configured separately with respect to the sealing cover and is connected to the sealing cover independently from the fastening element, the mating element having an axial projection inserted in the opening with at least one positively locking element extending radially outward inside the opening into the side cover radially past a circumferential face of the opening thereby forming a positive locking connection between the mating element and the sealing cover, an axial edge of the axial projection being inside the opening, the at least one positively locking element comprising an annular radial collar or radial tongues of the projection.
