Abstract
A valve case includes an attaching portion and a sleeve. The valve case is attached to a cylinder head cover main body formed of resin. The attaching portion is formed of resin and is a portion of the valve case to which an oil control valve is to be attached. The sleeve is embedded in the attaching portion, and 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 valve case prevents deformation of the attaching portion.
