According to the dustproof device of the present invention,
First, vibration can be prevented from being directly transmitted on the installation surface on which the structure is installed,
Second, vibration can be prevented from being transmitted through the vibration-proof spring and the elastic supporting portion corresponding to an external force in the horizontal direction as well as in the vertical direction,
Third, when the external force is out of the permissible range, the structure can be prevented from falling over or falling off from the mounting surface through the elastic supporting portion,
Fourth, the horizontal position of the structure can be adjusted by adjusting the joining position of the adjustment part,
Fifth, it is possible to apply the present invention to various structures such as a distribution panel, a motor control panel, a photovoltaic power generation device, an inverter, and a connection panel as well as a transmission and reception panel by using an anti-vibration device.
