PROBLEM TO BE SOLVED: To provide an anchor bolt that prevents a shaft body and a sleeve from rotating together when rotating a nut after fitting the nut to the bolt.SOLUTION: An anchor bolt 1 is inserted into a fitting hole 8 formed in a wall surface 85, and includes: a shaft body 2 whose tip end part is formed with an enlarged diameter part 20 and whose other end part is formed with a bolt 21, respectively, and in which the enlarged diameter part 20 has a taper-shaped outer peripheral surface; a sleeve 3 inserted from the other end part of the shaft body 2 so as to be in contact with and to cover an outer peripheral surface of the shaft body 2, and provided with expanding pieces 31 which bend outward along the enlarged diameter part 20 by being pushed further in with respect to the shaft body 2 when the shaft body 2 is in an insertion completed state into the fitting hole 8; and a fitting piece 43 for joining the shaft body 2 to the sleeve 3. The sleeve 3 is formed with a first groove 35 opened on a peripheral surface thereof, and a ring 4 being abutted to an inner peripheral surface of the fitting hole 8 is fitted in the first groove 35.SELECTED DRAWING: Figure 10
【課題】ボルトにナットを嵌めてナットを回転させる際に、軸体とスリーブが一緒に回転することを防ぐアンカーボルトを提供する。【解決手段】壁面85の取付け孔8に挿入されるアンカーボルト1であって、先端部に拡径部20を、他端部にボルト21を夫々形成し、拡径部21は外周面がテーパ状に形成された軸体2と、該軸体2の外周面に接して被さるように該軸体2の他端部から挿入され、軸体2の取付け孔8への挿入完了状態で軸体2に対して更に押し込まれることにより、拡径部20に沿って外向きに曲がる展開片31を設けたスリーブ3と、軸体2とスリーブ3とを連結する嵌合片43を備えている。スリーブ3の周面に第１凹溝35が開設され、該第１凹溝35内に取付け孔8の内周壁に接するリング4が嵌められている。【選択図】 図１０
