A camshaft adjuster () for an internal combustion engine of a motor vehicle with a radially outer stator () that can be driven by the crankshaft, a radially inner rotor () connected locked in rotation with the camshaft (), working chambers () that are arranged between the rotor () and the stator () and that can be pressurized with a pressure such that the relative rotational position of the rotor () to the stator () is adjustable, at least one seal cover () bordering the working chambers () on the sides and contacting the rotor () and the stator () in a sealing way, with an annular disk-shaped base body () and an annular projection () encompassing the camshaft () and adjacent to the radial inside of the base body (). The base body () contacts, with a seal surface (D), the rotor () and transitions via a radius () into the annular projection (). A bead () is provided on the annular disk-shaped base body () on the side facing away from the rotor () in the region bordering the annular projection ().
