<p>PROBLEM TO BE SOLVED: To provide an earthquake-resistant device provided with a function usually supporting the main body of the device with earthquake-resistance, and releasing the earthquake-resistant support of the main body of the device when the main body of the device reaches a resonant condition based on an earthquake motion.SOLUTION: An earthquake-resistant device according to an embodiment comprises: a main body of the device 1 provided on a base 5; a support member 2 supported by the base 5 and supporting the main body of the device 1; and a fastening member 3 fastening between the main body of the device 1 and the support member 2 releasably. The fastening member 3 usually fastens the support member 2 with the main body of the device 1, and releases the fastening state of the main body of the device 1 and the support member 2 when a vibration value for a resonance frequency based on an earthquake motion exceeds a reference value set in advance.</p> |
