In this paper, we estimated how the horizontal deformation characteristic changed when natural rubber bearing turned in vertical direction. In other words, we quantitatively estimated the influence which turning of the natural rubber bearing gave to the horizontal stiffness. The analysis resulted the knowledge mentioned below. 1. The relationship between the shearing force and the shearing strain estimated in this analysis can reproduce the results of the testing when the natural rubber bearing does not turn in vertical direction. The result of this analysis is highly reliable as far as the shape of the natural rubber bearing analyzed is concerned. 2. In this analysis, it was confirmed that the horizontal stiffness declined when natural rubber bearing turned in vertical direction and deformed around 200 % strain in shear. The larger the angle of turning degree, the more remarkable this tendency is, especially when turned 1/50 radian. 3. In the shearing strain area in this analysis, the change of the horizontal stiffness is within 10 % when natural rubber bearing turned in 1/150 radian.
