前記従来のせん断変形抑制弾性滑り支承装置の場合は、ゴム層がせん断変形さ れる。ゴム材は、これにせん断変形を与えると耐久性が短かくなるという性質が あるので、前記従来の弾性滑り支承装置の場合は、ゴム層の耐久性が短かいとい う欠点がある。 また前記従来の弾性滑り支承装置の場合は、縦孔が開放されているので、弾性 滑り支承装置の運搬中あるいは取扱中に、縦孔と係止部材との間に塵類その他の 異物が侵入する恐れがある。 In the case of the conventional elastic deformation support device for suppressing shear deformation, the rubber layer undergoes shear deformation. Since the rubber material has a property that its durability becomes short when it is subjected to shear deformation, the conventional elastic sliding bearing device has a drawback that the rubber layer has a short durability. Further, in the case of the conventional elastic slide bearing device, since the vertical hole is opened, dust or other foreign matter may enter between the vertical hole and the locking member during transportation or handling of the elastic slide bearing device. There is a risk of
