ABSTRACT:
A resin cylinder head cover includes an attaching portion and a sleeve. The attaching portion is formed of resin, and is a portion of the cylinder head cover to which the oil control valve is to be attached. The sleeve is embedded in the attaching portion. The sleeve has an interior space that permits the oil control valve to be accommodated therein and oil holes. Each oil hole is selectively connected to one of ports of the oil control valve accommodated in the interior space of the sleeve. The sleeve is formed of material having higher rigidity than the resin forming the attaching portion. Therefore, the cylinder head cover maintains highly reliable attachment of an oil control valve without a large number of high precision machining steps and prevents deformation of the attaching portion.
