PROBLEM TO BE SOLVED: To provide a hold down metal fitting in which a back plate part and a cylindrical part do not easily separate from each other even when a large load is applied to the hold down metal fitting by earthquake and the like.SOLUTION: A hold down metal fitting 1 includes a back plate part 11 fixed to a columnar member 3, and a cylindrical part 12 to which an anchor bolt 5, whose one end to is connected to a horizontal member 2, is inserted and fixed by a fastening nut 7. A pair of rising side-face parts and an arching back plate part are provided in the middle part of the back plate part 11, and an anchor bolt inserting part and a back plate middle part inserting part are provided in the cylindrical part 12. When the back plate part 11 is inserted into the cylindrical part 12, inner surfaces of back side-face part and both side-face parts of the cylindrical part 12 abut with outer surfaces of the pair of rising side-face parts and the arching back plate part of the back plate part 11, and at least each of the rising side-face parts of the back plate parts 11 and the back plate middle part inserting part of the cylindrical part 12 are welded to join the cylindrical part 12 to the back plate part 11.
【課題】地震などによりホールダウン金物に大きな荷重などが作用した場合でも、背板部と筒部とが分離し難くすることができるホールダウン金物を提供すること。【解決手段】ホールダウン金物１は、柱材３に固定される背板部１１と、一端が横架材２を介したアンカーボルト５が挿入されて締結ナット７により固定される筒部１２とを備え、背板部１１の中間部分には一対の起立側面部と浮き上り背板部とを設ける一方、筒部１２にはアンカーボルト軸挿入部と背板中間挿入部とを設け、背板部１１を筒部１２に挿入して、筒部１２の後側面部と両側面部の内側面が背板部１１の一対の起立側面部と浮き上り背板部の外側面に当接しており、少なくとも背板部１１の各起立側面部と筒部１２の背板中間挿入部とを溶接して筒部１２を背板部１１に接合した。【選択図】図１
