Abstract: In a camshaft for an internal combustion engine having a cam disk support shaft, to which a plurality of cam disks and a drive wheel are attached, the outer radius of the cam disk support shaft varies continuously in those sections in which the cam disks are attached. The cam disks have bores whose inner radius varies continuously and the cam disk support shaft is alternately provided with elevations and depressions in those sections in which the cam disks are attached, the elevations and depressions forming a wedge-shaped curve profile about the circumference of the section of the cam disk support shaft The elevations continuously enlarge the outer radius of the cam disk support shaft, the bores of the cam disks being matched to the enlarged portion of the outer radius of the cam disk support shaft, so that by relative rotation of the cam support shaft and the cam disks and also the drive wheel the components are firmly joined and the camshaft is formed.
