Provided is an anchor bolt that can be reliably held in a rock wall or the like, and is easily transported, stored, etc. This anchor bolt has expanding mechanisms (5) positioned in three locations on a rod (3). When the anchor bolt is inserted in a hole (2), free end sides of contact parts (16) of the expanding mechanisms (5) come into contact with the inner peripheral surface (26) of the hole (2), and expanding members (13) are held in the hole (2). In this state, tapered members (12) move to the base end side of the anchor bolt with the rod (3), bringing inclined surfaces (15) of the tapered members (12) into contact with inner surfaces (19) of the contact parts (16), and outer peripheral surfaces (20) of the contact parts (16) are pressed against the inner peripheral surface (26) of the hole (2). |
