PROBLEM TO BE SOLVED: To provide a hole-in anchor having a widening part that is entirely or partially of a rectangular plate-form when seen in a cross-section orthogonal to an anchor axis, the hole-in anchor being reusable and allowing pull-out readily.SOLUTION: A hole-in anchor includes a cylindrical body part, a widening part divided into a plurality of parts by a plurality of slits formed on a tip side of the body part, leaving a prescribed interval in a circumferential direction and extending in an axial direction, a female screw formed on an inner surface of the body part on a non-widening side, and a male screw body of a roughly cylindrical form that may be inserted into the body part, having a rear edge side screwed into the female screw. The widening part is of a roughly rectangular plate-form when seen on a cross-section orthogonal to an anchor axis, entirely or partially in a longer-side direction, and an inner surface near a tip of the widening part being tapered toward the tip side. By screwing the male screw body into the female screw and advancing the male screw body toward the tip side of the body part, a tip part of the male screw part comes in contact with the inner surface of the widening part to open and widen the widening part, and the widened widening part closes as the male screw body is retracted.SELECTED DRAWING: Figure 1
【課題】拡開部の長手方向の全部又は一部が、軸垂直断面視で長方形状の板状で、繰り返し使用可能で、抜き取りが容易に可能である。【解決手段】筒状の本体部と、本体部の先端側に形成され周方向に所定間隔をあけ且つ軸方向へ伸びる複数のスリットで複数に分割された拡開部と、本体部の非拡開部側の内面に形成された雌ネジと、本体部に挿入可能な略円柱状で、後端側が雌ネジに螺合される雄ネジ体とを備え、拡開部の長手方向の全部又は一部が、軸垂直断面視で略長方形状の板状の板状部であり、拡開部の先端付近の内面が、先端側へ行くに従って徐々に小径となるように形成され、雄ネジ体を雌ネジに螺合させて本体部の先端側へ前進させるに従って、雄ネジ体の先端部が拡開部の内面に当接して拡開部が開いて拡径し、雄ネジ体を後退させるに従って拡径した拡開部が閉じることを特徴とする。【選択図】図１
