摘要： A vibration isolator is composed of a cylindrical elastomer body and a cylindrical inner fixing member and an outer fixing member both made of a metallic material. The inner fixing member and the outer fixing member have flange parts formed along the edges thereof. The inner fixing member which has a smaller diameter than the outer fixing member is fixed to the inside diameter side of the elastomer body and the outer fixing member is fixed to the outside diameter side of the elastomer body. The elastomer body is formed of either an elastomer having a thermal conductivity in the range of from 1.3.times.10.sup.-3 to 7.1.times.10.sup.-3 cal/cm.cndot.sec.cndot..degree. C. or a elastomer composition containing 50 to 200 parts by weight per 100 parts by weight of rubber. The vibration isolator constructed as described above enables the spring constant in the direction perpendicular to the axis to be increased without reducing the effect of isolating vibration so as to decrease the displacement of the motor and improve the accuracy of positioning thereof. It also provides effective radiation of the heat generated by the motor and prevents the motor from temperature elevation.
