To provide a post-installed anchor that has a high anchorage force to prevent the anchor from being removed from concrete and can be easily removed when unnecessary.SOLUTION: A post-installed anchor 1 has: an inner member 2 having a taper portion 22 whose diameter increases gradually toward a front end on a front end side of a base 21; and a sleeve 3 having an extension piece 33 to be extended by entering of the taper portion 22 on a front side. A female screw hole 24 opening at a rear end surface 23 is provided on the inner member 2. A fitting bolt 4 can be screwed into the female screw hole 24. A spacer 5 extending in an axial direction is slidably inserted in an insertion hole 26 opening at a front end surface 25 of the inner member 2, and partially protrudes from the insertion hole 26 to the front end side.SELECTED DRAWING: Figure 3 【課題】高い定着力を有し、コンクリートからの抜け出しを防止することができると共に、不要時に容易に撤去することができるあと施工アンカーを提供する。【解決手段】基部２１の先端側に先端に向かって漸次拡径するテーパ部２２が設けられているインナー部材２と、先端側にテーパ部２２の入り込みで拡張する拡張片３３が設けられているスリーブ３を備え、インナー部材２に後端面２３で開口する雌ねじ穴２４が設けられ、雌ねじ穴２４に取付ボルト４を螺合可能であると共に、インナー部材２の先端面２５で開口する挿入穴２６に軸方向に延びるスペーサー５がスライド可能に挿入され、その一部が挿入穴２６から先端側に突出して設けられているあと施工アンカー１。【選択図】図３
