<p>PURPOSE:To simplify mounting work to a structural body by forming the cut line of the other end so that the contact surface of the other end to a through hole inner wall may become a tilted surface to approach the shaft core of a collar-like sleeve fixing member as its position is closer to the loose end side. CONSTITUTION:Cut lines L are provided on a plurality of parts in the circumferential direction of a collar surface part 8 of a collar-like sleeve fixing member 7, so as to form a bending objective part 18, and the other end 18B in the circumferential direction of the bending objective part 18 is bent inward from a through hole by bending one end 18A in the circumferential direction of the bending objective part 18 outward from the through hole, so as to be brought in contact with the through hole inner wall, thereby the position in the penetration sleeve 5 direction in the through hole can be determined. The cut line L of the other end 18B of the bending objective part 18 is so formed that the contact surface of the other end to the through hole inner wall may become the tilted surface to approach the shaft core of the collar-like sleeve fixing member 7 as its position is closer to the loose end side on the other end, thereby the other end can be made to be difficult to hook on the through hole inner wall.</p> |
