A camshaft assembly has a shaft and a cam that are formed independently and then assembled together. The cam includes an inclined section and a parallel section. The radius of the inclined section varies in the axial direction in at least one angular section of the cam, and the cross section of the parallel section is constant in the axial direction. The parallel section is adjacent to the inclined section and not contacted by the cam follower.
