SLIDE BEARING
PROBLEM TO BE SOLVED: To provide a slide bearing capable of supporting an item to be supported appropriately in sliding without producing any partial contact.SOLUTION: The present invention relates to a slip bearing unit 1 comprising a support 4 of which lower end part is fixed to a base 2 and which is buried in a concrete layer 3 installed on the base 2; a support plate 5 of disk attached to the upper end part of the support 4 and fixed to the upper surface of the concrete layer 3; and a slip sheet 7 made of low frictional material having, as major component, polytetrafluoroethylene fixed to the upper surface of the support plate 5 and contacted with an item 6 to be supported. The lower surface part of the support plate 5 is formed with a recess part 51 that expands downward and at the same time a top surface 41a at the upper end part of the support 4 is formed into a hemispherical shape having a smaller diameter than an opening diameter of the recess part 51, it is engaged with the upper end part of the support 4 at the recess part 51 of the support plate 5 to cause the support plate 5 to be supported in such a manner that it can be oscillated in a vertical direction, and a rubber resilient cap 8 having a through-pass hole 8c for the support 4 is fitted and closely contacted with the support plate 5 at its lower surface part and peripheral surface part.
【課題】被支承物を片当たりを生じることなく適正に滑り支承することができる滑り支承具を提供する。【解決手段】基盤２に下端部を固着され且つ基盤２上に打設されるコンクリート層３に埋没される支持具４と、支持具４の上端部に取り付けられて当該コンクリート層３の上面に固定される円板である支承板５と、支承板５の上面に固着されて被支承物６と接触するポリテトラフルオロエチレンを主成分とする低摩擦材製の滑りシート７とを具備する滑り支承具１において、支承板５の下面部に下拡がり状の凹部５１を形成すると共に支持具４の上端部の頂面４１ａを当該凹部５１の開口径より小径の半球状に形成して、支持具４の上端部にこれを支承板５の凹部５１に係合させることにより支承板５を上下揺動自在に支持させ、支持具４の貫通孔８ｃを設けたゴム製の弾性蓋８を支承板５にその下面部及び周面部に嵌合密着させてある。【選択図】図１
