(57) 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.
