be set accurately at 90 u00b0 as described with reference to fig6 however in the case of the vibration proofing device b having three rows of cylindrical rollers even if the angles formed between the upper intermediate and lower rollers 17 23 and 18 are not set accurately at 60 u00b0 since the rollers 17 23 and 18 compensate each other there is no danger of the upper structure 11 becoming unable to swing horizontally to exert the vibration proofing function in addition in the vibration proofing device b of this second embodiment the first and second intermediate pressure resisting plates 19a and 19b having elastomeric bodies 20a 21a 20b and 21b bonded thereto have been used however they are not absolutely necessary as in the case of the vibration proofing devices a 39 and a 34 in fig4 and 5 elastomeric bodies alone with no intermediate pressure resisting plates combined therewith may be interposed or intermediate pressure resisting plates with no elastomeric bodies bonded thereto may be interposed or the rollers 17 23 and 18 may be directly stacked using neither intermediate pressure resisting plates nor elastomeric bodies as for the elastomeric bodies used in the first and second embodiments described above those which have a poor damping property may be used however since the rolling surfaces of the elastomeric bodies locally moved up and down as the rollers 17 18 and 23 roll the performance of the vibration proofing device can be further improved by using elastomeric bodies of high damping property which are capable of absorbing greater.
