Abstract

The present invention relates to a cylinder head cover (4) for covering a cylinder crank case (14) of an internal combustion engine. It is essential to the invention here that at least one bearing upper part (3) for a camshaft (2) has at least one through-opening (5), which is in alignment on the one hand with a screw-in/through-opening (5a) in a bearing lower part (6) and/or with a screw-in opening (5b) in the cylinder crank case (14) and on the other hand with a through-opening (5c) in the cylinder head cover (4), so that it is possible to fasten the cylinder head cover (4) and the bearing upper part (3) on the cylinder crank case (14) by means of a shared fastening screw (7), in which the cylinder head cover (4) is produced from a material which has different material characteristics from the at least one bearing upper part (3).
