PURPOSE:To obtain a coil spring with a low natural frequency and a short length in an oscillation isolating supporting device by providing a coil spring having an elastic strain which causes the displacement of the coil spring to extend to a defined length in an unrestricted condition. CONSTITUTION:Four cylindrical installing members 13 are fixed to the top face of a base 10. And, a cylindrical coil spring 15 is placed in each of the cylindrical installing members 13. The coil spring has an elastic strain which always causes a displacement of the coil spring to extend to a defined length with the positions of both ends being reversed. Thereby, an oscillation isolating supporting device using the coil spring 15 which can obtain a low natural frequency of 1Hz or less can be formed, enabling a shock absorbing device using a short coil spring to be simply formed. |
