<p>Provided are: an anchor bolt capable of fixing firmly in a hole provided in a concrete wall, etc.; and a production method therefor. This anchor bolt has: four contact sections (12) that form inside surfaces (14) capable of coming in surface-contact with a sloping surface (11) of a tapered member (7); and a bridging section (13) formed by a main body section (13a) and connection sections (13b) that fix the tips of the contact sections (12). A rod section (3) having a male screw (9) is connected to the tapered member (7). The sloping surface (11) of the tapered member (7) gets closer to the center axis of the tapered member (7) the closer same is to the base side of the anchor bolt. The outer peripheral surfaces (15) of the contact sections (12) can be in surface-contact with the inner peripheral surface (4) of a hole (2) in a wall surface (1), in a state in which the inside surfaces (14) of the contact sections (12) are in surface-contact with the sloping surface (11) of the tapered member (7). The connection sections (13b) of the bridging section (13) are formed in an inclined shape so as to be further away, in a free state, from the tapered member (7) the closer same are to the free end side of the contact section (12).</p> |
