note = {This paper deals with the pressure generated btween two flat disks in the fluid, one lower disk fixed and another upper disk moved perpendicular to the fixed lower one. Results obtained from the experiment are as follows :When the upper disk approaches the lower one, viscoelasticity of the fluid decreases the pressure below the pressure of corresponding Newtonian fluids, whereas in the case of separating the upper disk from the lower one, the pressure takes minus values of about - 3.5 × 10^5Pa and the magnitude is increased by the viscoelasticity of the fluid used. This minus pressure is raised to a vacuum pressure by the cavitation inception inferred, the vacuum pressure holds constant for a duration and finally the pressure abruptly increases by the cavity extinction which accompanies pressure vibrations of high frequencies. These experimental results are qualitatively explained using the assumption of squeezing flow and the constitutive equation of the second order fluid.},
