[Solution] A sleeve impact type post-construction anchor 10 that is anchored in an anchor hole 1 in which an expanded diameter portion 4 is formed at a position at a prescribed depth in a pilot hole 3 comprises: a sleeve unit 11 having an expanding portion 22 on the distal end; an anchor body 12 that is inserted into the sleeve unit 11 and that has male threads 12a formed on at least the distal end; and a cone portion 13 that has a tapered portion 13a to expand the expanding portion 22 and that screws onto the distal end of the anchor body 12 so that the position thereof is adjustable. The cone portion 13 is formed in the axial direction to a length corresponding to the length of the expanded diameter portion 4 and to be longer than the distance from the bottom 3c of the pilot hole 3 to the bottom part 4a of the expanded diameter portion 4.
