Damping structure

A damping structure comprising:

• a first frame including a first plate;
• a driving motor provided on the first plate of the first frame;
• a second frame provided at a position facing the first frame and including a second plate opposite to the first plate, the second frame being configured to support the first frame in such a manner that a gap is provided between the first and second plates;
• a projecting portion provided in the gap and configured to project from one plate toward the other plate of the first and second plates;
• a press member provided at a tip of the projecting portion and whose area is larger than an area of an end surface of the tip of the projecting portion;
• and
• a damping member provided on the press member so as to be compressively held between the press member and the other plate, the damping member (i) having a rigidity lower than rigidities of the first frame, second frame, and the projecting portion and (ii) having a loss factor, measured by a mechanical impedance method in the state being compressed between the press member and the other plate, of 0.05 or more.
