<P>PROBLEM TO BE SOLVED: To provide a vibration isolation mount which uses nonlinear springs and yet obtains a stable spring constant irrespective of a value of a load to be vibration-isolated. <P>SOLUTION: The vibration isolation mount 1 is provided in which an upper plate 5 positioning a vibration isolation object to a positioning seat 11 is stably supported by a base plate 3 at a plurality of points via the arrangement of the nonlinear springs 7a, 7b, 7c, 7d. The vibration isolation mount includes a position changing functioning part which adjust a combined spring constant by changing the stable supporting position between the positioning seat 11 and nonlinear springs 7a, 7b, 7c, 7d. The position changing functioning part includes the positioning seat 11 which is fixed to the upper plate 5 in such a manner that the fastening position can be changed, and is configured by including a plurality of screw holes 15a, 15b, 17a, 17b, 19a, 19b, 21a, 21b enabling the fastening position of the positioning seat 11 to be changed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
