【００１２】
【発明の実施の形態】
図１〜図５は、本発明の一実施形態を備えるテーブルを示す。
【００１３】
このテーブルは、前後方向に長い水平脚（１）の後部上面に、前後方向に長い長円形断面の起立脚（２）を立設し、この起立脚（２）の上端に、水平脚（１）とほぼ上下対称形をなす前方を向く支持アーム（３）の後端部を固着し、この水平脚（１）と起立脚（２）と支持アーム（３）とにより形成された左右１対の脚（４）をもって、ほぼ水平の天板（５）の両側部を支持したものよりなっている。
【００１４】
水平脚（１）の前端部下面には、上端が閉塞された上方を向くねじ孔（６）が穿設されており、ここに、下端に円形の脚座（７）が固着された上方を向くアジャスタボルト（８）が螺合され、このアジャスタボルト（８）を回転させることにより、水平脚（１）の前端部（７）の床面からの高さを自由に調節し得るようになっている。
【００１５】
水平脚（１）の後端部下面には、方形の凹部（９）が設けられており、この凹部（９）の上壁（１０）の中央には通孔（１１）が、またその前部には上下方向を向くスリット（１２）がそれぞれ穿設されている。
【００１６】
水平脚（１）の後部上面には、起立脚（２）との位置決め用の複数の突部（１３）（１４）（１５）（１６）が設けられており、その最も後方の突部（１３）の中央に上記通孔（１１）が貫通している。また、最も前方の突部（１６）の中央には、通孔（１１）と同様の上下方向を向く通孔（１７）が貫通している。
【００１７】
起立脚（２）の下面には、その外形と相似形をなす凹所（１８）が形成されており、この凹所（１８）に上記突部（１３）（１４）（１５）（１６）を嵌合することにより、水平脚（１）と起立脚（２）とは、それらの後端同士が互いに上下方向に整合するように位置決めされ、かつ前後の通孔（１７）（１１）に下方より挿通した止めねじ（１９）（１９）の上部を、起立脚（２）の下端面に形成したねじ孔（２０）に螺合して締着することにより、互いに強固に結合されている。
【００１８】
水平脚（１）の後端部下面における凹部（９）には、中央に上下方向を向くねじ孔（２１）が設けられたアジャスタ受材（２２）が嵌合されている。
アジャスタ受材（２２）は、ねじ孔（２１）が中央に設けられた平面視方形の底板（２３）と、その前縁及び両側縁より起立する前面板（２４）及び両側板（２５）（２５）とを備えている。
【００１９】
凹部（９）に嵌合する前のアジャスタ受材（２２）における各側板（２５）の前後方向の幅は、凹部（９）の前後幅より若干大としてあり、また各側板（２５）の前後方向の中間部に、上端より下方を向くスリット（２６）を設けることにより、各側板（２５）の後部に、上方を向く弾性撓曲片（２５ａ）が形成されている。
【００２０】
したがって、アジャスタ受材（２２）を凹部（９）へ圧嵌したとき、弾性撓曲片（２５ａ）がスリット（２６）に向かって弾性変形することができるようになっている。
【００２１】
前面板（２４）の上端中央には、上方を向く突片（２７）が突設されており、この突片（２７）を、水平脚（１）における凹部（９）の上壁（１０）における通孔（１１）より前方に設けられた上述のスリット（１２）に嵌合し、かつスリット（１２）を貫通して水平脚（１）より上方に突出する突片（２７）の側面に設けた係止爪（２７ａ）を、水平脚（１）の上面に係止させることにより、アジャスタ受材（２２）は凹部（９）より抜け止めされている。
