To provide a rubber bearing body which is of a laminate structure formed by alternately laminating, on each other, rubber layers made of chloroprene rubber and rigid plates having rigidity, such as metal plates, wherein the rubber bearing body ensures the adhesiveness between the rubber layers and the rigid plates to a high degree while improving the low-temperature characteristics thereof.

The rubber bearing body 10 is formed by alternately laminating the rigid plates 14 having rigidity and the rubber layers 16 on each other. The rubber layer 16 is made of a rubber composition which contains a polymer material mainly consisting of the chloroprene rubber, in an amount of 100 pts.wt., dioctyl phthalate of 8 to 25 pts.wt. mixed in the polymer material, and silica of 3 to 15 pts.wt. further mixed in the same.
