A cylinder head cover is formed by a synthetic resin outer shell, which is molded by inserting a metal valve case, which holds a oil control valve, in a mold. The valve case has a bolt fastening portion for fastening the valve case, together with the outer shell, to the cam cap. The valve fastening portion has a bolt insertion hole. The bolt fastening portion also has a flange that extends radially outward. The flange has through holes. The flange is embedded in the outer shell, and synthetic resin forming the outer shell fills the through holes.
