。In an engine cylinder head cover sound insulation structure configured to include a sound insulation cover that covers the cylinder head cover at a predetermined gap outside the cylinder head cover,
The cylinder head cover is fixed to the cylinder head by the cylinder head cover mounting bolt inserted into the through hole formed in the cylinder head cover, and the cylinder head cover is fixed to the cylinder head via a washer that provides an oil-tight seal between the head of the bolt and the cylinder head cover. A through hole corresponding to the through hole of the cylinder head cover is formed in the cover, and a vibration damping member is disposed in the through hole portion, thereby forming a predetermined gap between the cylinder head cover and the sound insulation cover, and A sound insulating structure for a cylinder head cover for an engine, characterized in that the sound insulating cover is attached via a vibration damping member by means of a nut screwed into a screw portion protruding above the head of the cylinder head cover mounting bolt.
