Abstract

A sound absorbing cover is made of foam containing magnetic filler and is integrally molded in a three-dimensional shape so as to cover at least a part of a mating member that is a noise source. The sound absorbing cover includes side walls that cover side surfaces of the mating member and a bottom wall that covers a bottom surface of the mating member that intersects with the side surfaces of the mating member. The magnetic filler is oriented in a thickness direction of each of the side walls and the bottom wall. A sound absorbing assembly includes the sound absorbing cover and a fixing cover that is attached to the outer peripheral surface of the sound absorbing cover and that fixes, to a base, the sound absorbing cover and the mating member that is a noise source covered by the sound absorbing cover.
