Abstract
A lid adapted to be mounted on the cylinder head of an internal combustion engine by attachment screws includes a cap and a carrier element adapted to be attached to the cylinder head by the attachment screws. To achieve an improved sound decoupling, the cap and the carrier element are connected to an elastomer component, with the connection between the cap and the carrier element being, at least in part, exclusively constructed by the elastomer component, and with a space being provided between the cap and the carrier element. The carrier element possesses a substantially straight section arranged to extending preferably at a right angle to the attachment surface of the cylinder head, the substantially straight section of the carrier element, a portion of the elastomer component adjacent the cap, and a portion of the cap adjacent the carrier element extend in a straight line.
