The present invention relates to a vibration-proof apparatus for a switchgear, which is installed on a floor structure (200) to support a switchgear (100). The vibration-proof apparatus includes a cylinder container (10) coupled with a floor structure (200) and having an internal space (22). A vibration-isolation spring (12) is installed in the internal space of the cylinder container (10), and a support member (14), which is coupled with the switchgear (100), is placed on a free end portion of the vibration-isolation spring (12). The support member (14) is movable up, down, left, and right with the cylinder container (10). The vibration-proof apparatus prevents vibration from being applied to the switchgear (100) even vibration occurs by earthquake or external shock and reduces noise. In addition, the vibration-proof apparatus is simple and durable and the manufacturing costs of the vibration-proof apparatus are reduced. |
