コストで製造できる等の効果が得られる。 According to this invention, the steel lower bearing stopper 3
is embedded deeply to the extent that the upper bearing surface 4 thereof is located on the same plane as the receiving surface 5 of the seat 2 of the support structure 1, and the steel upper bearing stopper 8 is
Since the lower support surface 9 in this case is buried deep enough to be located on the same plane as the mounting surface 10 of the mounting seat 7 of the supported structure 6, the lower support stopper 3 and the upper support stopper against horizontal force are The embedded fixation strength of No. 8 is extremely high and stable,
Furthermore, since the horizontal force bearing protrusion 11 on the lower bearing stopper 3 is inserted into the horizontal force bearing recess 12 in the upper bearing stopper 8, it exerts a large supporting force against horizontal seismic forces, etc. The lower surface of the fitted vertical force bearing rubber shoe 13 is placed across the upper support surface 4 and the receiving surface 5, and the lower support surface 9 and mounting surface 10 are placed on the upper surface of the rubber shoe 13. Therefore, the lower support stopper 3 and the upper support stopper 8 are completely covered by the catch 2, the mounting seat 7, and the rubber shoe 13, so that the catch 2, the mounting seat 7, and the rubber shoe 13 can be used skillfully. The lower bearing stopper 3 and the upper bearing stopper 8 can be completely covered to prevent corrosion thereof, and furthermore, the horizontal force bearing protrusion 11 can be used to prevent the displacement movement of the vertical force bearing rubber shoe 13. This can be reliably prevented, and since the planar shapes of the lower support stopper 3 and the upper support stopper 8 are smaller than the rubber shoe 13, effects such as reduction in size and weight and manufacturing at low cost can be obtained.
