[Challenge] it is possible to change the height to easily adjust the depth of insertion of the pillar with respect to the support tube portion, to provide a high handrail stand of load bearing. A height adjustment screw 8 is intended to be screwed attached to one of a number of large-diameter screw holes 4b of the support cylinder 4, of the support tube portion across the supporting cylinder unit It is intended to adjust the bottom to be received insertion depth of the pillar of the pillar 3a being inserted into the support tube portion by being supported bracing pressed against the wall, and a large-diameter threaded hole 4b only in the longitudinal direction end side region screwed to the male screw portion 8a is provided on the outer peripheral surface in the longitudinal direction of the remaining area entire area is formed smaller in diameter than the circular a and the large diameter screw holes 4b to. .BACKGROUND【課題】支持筒部に対する柱の挿入深さを簡単に調整して高さを変更できると共に、耐荷重性の高い手摺スタンドを提供する。【解決手段】高さ調整ねじ8は、支持筒部4の多数の大径ねじ孔4bのうちのいずれか1つに螺合装着されるもので、支持筒部を横切って支持筒部の内壁面に押し付けられ突っ張り支持されることによって支持筒部内に挿入されている柱3aの底部を受け止めて柱の挿入深さを調整するものであり、その長手方向一端側領域にのみ大径ねじ孔4bに螺合する雄ねじ部8aが設けられ、長手方向の残り領域全域の外周面が円形でかつ大径ねじ孔4bよりも小径に形成されている。【選択図】図3
