PROBLEM TO BE SOLVED: To provide a newly structured hole-hanging clamp capable of efficiently and safely hole-hanging a variety of workpieces with a different thickness.SOLUTION: The hole-hanging clamp comprises: a shaft which is arranged movable in the axial direction relative to a main body sleeve 11, and has a main body bolt 21 protruding from its one end in the axial direction and an insertion end part 22 protruding from its other end in the axial direction; a movable plate 26 which takes a protruded position (indicated by a two-dot chain line in Fig. 5) protruded from both sides of the insertion end part and an embedded position (indicated by a solid line in Fig. 5) embedded in the insertion end part; a compression spring 30 for always energizing the movable plate toward the protruded position; and an opening button 27 which is arranged within a head part 21a of the main body bolt, and turns by its push-in operation the movable plate toward the embedded position, against the energization force of the compression spring. The hole-hanging clamp can be attached to a workpiece by only an operation from one side of the workpiece. The gap between the main body sleeve and the movable plate can be adjusted in accordance with the thickness of the workpiece by moving the main body bold in the axial direction. 【課題】異なる肉厚を有する多種多様なワークを効率的且つ安全に穴吊りすることができる新規構成の穴吊りクランプを提供する。【解決手段】本体スリーブ１１に対して軸方向に移動可能に設けられてその軸方向一端から突出する本体ボルト２１とその軸方向他端から突出する挿入端部２２とを有するシャフトと、挿入端部の両側に突出する突出位置（図５二点鎖線）と挿入端部内に収容される埋没位置（図５実線）とを取る可動プレート２６と、可動プレートを常に突出位置に向けて付勢する圧縮バネ３０と、本体ボルト頭部２１ａに内設されてその押し込み動作により圧縮バネの付勢力に抗して可動プレートを埋没位置に向けて回転させる開放ボタン２７とを有する。ワークの片側からの操作のみでワークに装着することができる。本体ボルトを軸方向に移動させて、ワークの肉厚に応じて本体スリーブと可動プレートとの間の間隔を調整する。【選択図】図５
