PROBLEM TO BE SOLVED: To provide a vibration testing machine which can prevent an increase in weight and is excellent in economic efficiency.SOLUTION: A vibration testing machine T is provided with an actuator A which excites a test piece W, and a vibration-proofing device S which inhibits vibration of the actuator A from being transmitted to an installation surface F, and is mounted on the installation surface F. The vibration-proofing device S includes a spring element 5 interposed between the installation surface F and the actuator A; and an attenuation element D interposed between the installation surface F and the actuator A in parallel to the spring element 5. |
