Abstract
(EN)
Provided is a novel sound-proofing cover which has adequate sound-proofing performance and excellent heat resistance. The sound-proofing cover comprises: a sound-proofing covering; and a heat-shielding plate provided at a distance above the sound-proofing covering. Preferably, the distance between the abovementioned sound-proofing covering and heat-shielding plate which are provided at a distance from one another exceeds 0 mm but does not exceed 30 mm, and the heat-shielding plate and sound-proofing covering are held while maintaining a distance therebetween, and linkages each comprising at least a support member which is inserted into insertion holes provided in corresponding positions in the heat-shielding plate and the sound-proofing covering, and an intermediate shock-absorbing member of the support member, comprising a metal mesh inserted between the heat-shielding plate and the sound-proofing covering.
