という欠点がある。In the case of the conventional sliding type rubber bearing, the tetrafluoroethylene plate having the flat upper sliding surface is in surface contact with the stainless steel plate having the flat lower sliding surface. Therefore, there is a drawback in that the tetrafluoroethylene plate is adsorbed on the stainless steel plate and is less likely to slide and move.
