PROBLEM TO BE SOLVED: To provide an anchor bolt which can alleviate a time and labor or the like of assembling work even if a rod is long.SOLUTION: This anchor blot has a rod 4, a tapered member 7 and an expanded member 8. The expanded member 8 has an abutment part 12 whose internal face 11 abuts on an external peripheral face of the tapered member 7. Since the external peripheral face of the tapered member 7 push-presses an internal peripheral face 11 of the abutment part 12 accompanied by the rotation of the rod 4, an external peripheral face 15 of the abutment part 12 is push-pressed against an internal peripheral face 2a of an attachment hole 2, and the anchor bolt is fixed to the internal peripheral face 2a of the attachment hole 2. The tapered member 7 is divided into tapered pieces, and the tapered pieces have female screw portions. Protrusions and recesses which are engaged with each other are arranged at divided faces of the tapered pieces, the protrusions and the recesses are engaged with each other with male screws 3 of the rod 4 sandwiched between the female screw portions of the tapered pieces, and female screws 6 of the tapered pieces 7 are screwed to the male screws 3 of the rod 4. |
