FLOOR POST

To provide a floor post capable of improving work efficiency in a height adjustment of a floor substrate panel.SOLUTION: In a floor post 1, an axial position of a second pillar 4 movable with respect to a first pillar 3 erected on a base surface 9, is adjusted by an adjustment mechanism 5. The adjustment mechanism 5 comprises: an operating member 6 movably out-fitted in the axial direction with respect to the first pillar 3; and a connecting member 7 for connecting the second pillar 4 and the operation member 6. The operation member 6 has: an operating portion 61 having a female thread 6A screwed with a male thread 31 of the first pillar 3; and an insertion portion 62 inserted into a cylindrical portion 41 of the second pillar 4. The connecting member 7 has: a connecting body 71; and a first engaging portion 72 and a second engaging portion 73 provided on the connecting body 71. The first engaging portion 72 is engaged with a first engaged portion 411 of the cylindrical portion 41 in the second pillar 4, and a second engaging portion 73 is engaged with a second engaged portion 621 of the insertion portion 62 in the operation member 6.SELECTED DRAWING: Figure 1 【課題】床下地パネルの高さ調整の作業効率の向上を図ることが可能な床束を提供する。【解決手段】床束１では、基盤面９に立設された第１支柱３に対して移動自在な第２支柱４の軸方向の位置を、調整機構５によって調整する。調整機構５は、第１支柱３に対して軸方向に移動自在に外挿される操作部材６と、第２支柱４と操作部材６とを連結する連結部材７と、を含む。操作部材６は、第１支柱３の雄ネジ部３１と螺合する雌ネジ部６Ａを有する操作部６１と、第２支柱４の筒状部４１内に挿入される挿入部６２と、を有する。連結部材７は、連結本体部７１と、連結本体部７１に設けられた第１係合部７２及び第２係合部７３と、を有する。第１係合部７２は第２支柱４における筒状部４１の第１被係合部４１１に係合し、第２係合部７３は操作部材６における挿入部６２の第２被係合部６２１に係合する。【選択図】図１
