This anchor bolt (40) has: a tapered member (7) with which a rod (4) engages through threads; and three or five contact sections (12) fitted over the tapered member (7). The tapered member (7) has a regular triangular or regular pentagonal cross-sectional shape, and the sides of the tapered member (7) have three or five sloped surfaces (10) which are sloped so as to be closer to the center axis of the tapered member (7) as the sloped surfaces approach the base end. The contact sections (12) are sloped so as to be closer to the center axis of the tapered member (7) as the contact sections (12) approach the base end, and the contact sections (12) have inner surfaces (11) coming into contact with the sloped surfaces (10) of the tapered member (7). Moving only the tapered member (7) toward an opening of a mounting hole (2) while the tapered member (7) and the contact sections (12) are inserted in the mounting hole (2) causes the outer peripheral surfaces (15) of the contact sections (12) to be pressed against the inner peripheral surface (2a) of the mounting hole (2) to affix the contact sections (12) to the mounting hole (2). |
