VIBRATION ISOLATING DEVICE, AND FACILITY HAVING PIPE OR DUCT SUPPORTED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive and maintenance-free vibration isolating device capable of reducing the vibration of vibrating body with an excitation force (dynamic displacement) applied thereto but non-resistant against the thermal expansion displacement due to temperature change (static displacement), and a facility having a pipe or a duct supported thereby. SOLUTION: This vibration isolating device for reducing the vibration of the vibrating body with the excitation force applied thereto comprises a supporting member for movably supporting the vibrating body in the direction of the thermal expansion displacement, and an inertial mass body with an inertia force against the excitation force applied thereto.
