Provided is a vibration prevention device in which deterioration of an elastic member for linking together a supporting body and a vibrating body is minimized, and in which there is little change over time in spring characteristics. A vibration prevention device (an engine mount (1)) provided with: an elastic member (30) for linking together a supporting body (e.g., a body frame or the like to which a body-side attachment member (10) is attached) and a vibrating body (e.g., an engine or the like to which an engine-side attachment member (20) is attached), the elastic member (30) having a diene-based rubber as the primary component; an outside air blocking member (40) for covering the elastic member (30) and blocking contact between the elastic member (30) and outside air; and a gas-absorbing body (60) sealed in a sealed space (50A) that is partitioned by the outside air blocking member (40), wherein the gas-absorbing body (60) includes a substance that absorbs gas produced by the heat-deterioration of the elastic member (30), and comprises a substance that does not produce a sulfur compound and/or carbon dioxide due to the heat-deterioration of the gas-absorbing body (60) itself. |
