という問題点を有していた。In the first construction method among those described in the prior art, although the one satisfying both accuracy and characteristics can be obtained, when the conventional vulcanized rubber is adopted. The polishing work is very difficult, it is difficult to maintain a constant friction coefficient, and the process for obtaining a uniform thin film thickness is troublesome, which is a complicated and expensive work.
Further, in order to vulcanize and bond the rubber to the turntable, it is necessary to mix the solvents for degreasing the turntable, the solvent contained in the adhesive, etc. in order to increase the adhesive strength, which makes the work complicated. However, there is a problem in that it becomes an environmental pollution problem due to the harmfulness of solvents. In addition, in the second conventional construction method, by using the double-sided adhesive tape, the influence of heat,
In particular, there is a problem that the double-sided adhesive tape is peeled off due to thermal strain deformation at a high temperature and the rubber plate and the elastomer plate are displaced.
