PROBLEM TO BE SOLVED: To provide an easily extractable anchor pin. SOLUTION: This invention is premised on the anchor pin 11 having a holding shaft part 16 to be held in an installation hole 9, and a head part 17 arranged in a base end part of the holding shaft part in a state of expanding a diameter more than the holding shaft part 16. In this anchor pin 11, the head part 17 has a first head part 17a arranged on the base end of the holding shaft part 16, and a second head part 17b arranged at an interval on the inner side in the axial direction of the holding shaft part 16 more than the first head part 17a. A space between the first head part 17a and the second head part 17b is formed into an extracting tool inserting space 20. An extracting tool 22 is inserted into the extracting tool inserting space 20, to engage the first head part 17a with the extracting tool 22. COPYRIGHT: (C)2005,JPO&NCIPI
