An anti-vibration device, which reduces vibration between an object and an installation surface on which the object is installed, the anti-vibration device comprising:

• a first elastic member;
• a first support member disposed to cover the first elastic member and fastened to the first elastic member;
• a second elastic member disposed on an upper portion of the first support member;
• and
• a second support member disposed to cover the second elastic member and fastened to the first support member,
• wherein only a part of an outer surface of the first elastic member is in contact with the first support member such that a space is formed between the first elastic member and the first support member,
• wherein the first support member comprises:
• a first cover plate configured to support an upper surface of the first elastic member and fastened to the first elastic member;
• wherein the second support member comprises:
• a second cover plate configured to support an upper surface of the second elastic member;
• and
• a second sidewall connected to a lower portion of the second cover plate and configured to cover a lateral surface of the second elastic member,
• wherein the first cover plate, the first elastic member, the second cover plate, and the second elastic member each have a through-hole provided in a central portion thereof, the anti-vibration device further comprises a first nut inserted into the through-hole of the first elastic member and having a flange configured to support a lower surface of the first elastic member, and the second cover plate, the second elastic member, the first cover plate, and the first elastic member are fastened to one another by a bolt coupled to the first nut while penetrating the second cover plate, the second elastic member, the first cover plate, and the first elastic member, and
• a second nut provided between the first cover plate and the second cover plate, disposed in the through-hole of the second elastic member, and fastened to the bolt.
