Zusammenfassung:To provide an anchor which has no risk of damaging or breaking a concrete wall and is easy to fix to the concrete wall, and a footrest using the anchor.SOLUTION: An anchor is composed of a cylindrical body and an expanded cone, and a split groove is formed in a part including one end of the cylindrical body at a position opposed to each other in the circumference, and the expanded cone is composed of a main body and a cone pin. The main body has a truncated cone shape, and an outer diameter of a cross section of one end part is smaller than an inner diameter of the cylindrical body, and the outer diameter of the cross section of the other end part is larger than the inner diameter of the cylindrical body. The cone pin penetrates a head of the main body in a direction perpendicular to an axial direction of the main body, and both ends thereof protrude outside the main body. A footrest has a stepping part and leg parts on both sides thereof, and the anchor is connected to the leg parts.SELECTED DRAWING: Figure 1 【課題】コンクリート壁を損傷・破壊する恐れがなく、かつコンクリート壁に固定する作業が容易であるアンカー、該アンカーを使用した足掛け具等を提供する。【解決手段】アンカーは、円筒体と拡開コーンからなり、円筒体の一方の端部を含む部位には、円周において互いに対向する位置に割り溝が形成され、拡開コーンは本体とコーンピンからなり、本体は、形状が円錐台状であり、一方の端部の断面の外径が円筒体の内径よりも小さいとともに、他方の端部の断面の外径が円筒体の内径よりも大きく、コーンピンは、本体の軸方向に対して直角の方向に本体の頭部を貫通してその両端部が本体外に飛び出ている。足掛け具は、足踏み部とその両側に脚部を有し、脚部には上記のアンカーが接続されている。【選択図】図1
