PURPOSE:To permit the assembly, averting an obstacle which interferes with a seat metal on an insertion line, by tilting the top edge of a bolt by an automatic assembling machine, etc. positioning the bolt at an insertion port, and dropping the seat metal along the bolt and returning the top edge of the bolt to an original angle. CONSTITUTION:When cylinders 31 and 32 are moved, a bolt 37 is held by a pushing-in rod 41 and a chuck arm 47, and a nut 52 is held onto a holder arm 50 and set at the insertion positions X and Y. When the arm 10 of the three- formed arm 13 of a pivotal shaft 9 supported onto a main frame 7 is moved leftward by a cylinder 14, arms 28 and 30 are moved, and in the swing frames 21 and 22, the rollers 23, 24 and 25, 26 are shifted to 23', 24' and 25', 26, guided by cam grooves 17a and 18a, and swing shafts 27 and 29 shift to 27' and 29' and are swung right and left around the top edge of the bolt, and each posture of X' and Y' is formed. At the same time, a holder arm 50 is opened, and a seat metal 52 is dropped into an insertion port 56, averting an obstacle 57b, and when the cylinder 14 returns, each posture of X and Y is formed again.
