Abstract

A soundproof member is mounted on a structure including a rotation body, covers at least a part of outer peripheral surfaces of the structure, includes an integral article of an elastic member, and has eccentrically located portions having at least a greater thickness or a greater density than the other portions. The eccentrically located portions may be thick wall portions having a greater thickness than the other portions. When the elastic member has a base material including polymer and a magnetic filler included in a state of being oriented in the base material, highly filled portions in which a content of the magnetic filler is greater than that of the other portions can be set as the eccentrically located portions.
