Abstract
A dumping structure includes a first frame on which a driving portion is mounted, a second frame, a fixture fixing the first frame to the second frame, a restrict portion, provided around the fixture and provided between the first and second frames, which restricts a distance between the first and second frames, and a damping member, provided around the restrict portion, which is compressed by the first and second frame. The damping member has rigidity lower than rigidity of the first frame, rigidity of the second frame and rigidity of the restrict portion, and has a loss factor, measured by a mechanical impedance method in the state being compressed between the first and second frames, of 0.05 or more.
