Abstract

A noise reducing cover (10) comprising a retainer member (24) secured to a structural member (12) capable of being vibrated and formed with a groove (24b), a cover member (11) whose major part (22) is made of a material high in damping capacity, the cover member being formed with an edge section (11a) which is disposed within the retainer member groove (24b), and an elastic member (28) interposed between the surface of the retainer member groove (24b) and the surface of the cover member edge section (11a), thereby effectively preventing the vibration of the vibrating structural member (12) from transmitting to the cover member and preventing noise emission from the cover member surface.
