The base leg for the operating table isColumn base (4) to connect the column base (2) to the floorThe head support part (6) of the height adjustable column base for supporting the head of the base leg (2) andAn elevating and driving device (7) for adjusting the height of a column base support portion (6) to a base of a column base (4) andA column support portion (6) is connected to the base of the column baseThe main guide part (10) of the cylindrical shape which serves to provide the vertical guide of the column base head support part (6) in the height adjustment of the column base head support part (6) and.The additional stabilizing guide part (20) connects the column base head support portion (6) to the base of the column base (4), reduces the play in the rotation of the main guide part (10) of the cylindrical shape, and also serves to provide a guide perpendicular to the leg support portion (6) when adjusting the height of the column support head Want to be among the first to wish you every happiness.Diagram手術台の為の台柱脚（２）は、床面に台柱脚（２）を接続する為の柱脚基部（４）と、台柱脚（２）の頭部を支持する為の高さ調整可能な柱脚頭部支持部（６）と、柱脚基部（４）に対する柱脚頭部支持部（６）の高さを調整する為の昇降駆動装置（７）と、柱脚基部（４）に柱脚頭部支持部（６）を接続し、柱脚頭部支持部（６）を高さ調整する際に柱脚頭部支持部（６）の垂直な案内を提供する役割を果たす円筒状の主要な案内部（１０）と、を含む。付加的な安定化案内部（２０）は、柱脚基部（４）に柱脚頭部支持部（６）を接続し、円筒状の主要な案内部（１０）の回転に於ける遊びを減少させ乍らも、柱脚頭部支持部（６）を高さ調整する際に柱脚頭部支持部（６）に垂直な案内を提供する役割を果たす。【選択図】図３
