PURPOSE:To reduce working time by working arranging three or more die at an equal interval in a radial form an thereby decreasing the swaging area per die. CONSTITUTION:When a spindle is rotated being drive by a motor, a swaging roller 22 being in a line contact makes a rolling motion and moves towards a direction same as that of the spindle. In the meantime, hammer rollers 16a-16c fitted to swaging hammers 15a-15c roll being in contact each other alternately and synchronously with a roller cage 21 and swaging roller 22. When the hammer rollers 16a-16c move from the roller cage 21 to the roller 22, each of the hammer 15a-15c, washers 14a-14c and dies 11a-11c displace simultaneously towards the center direction. The wire rod inserted to a work hole 13 formed by cut parts 12a-12c of a circular arc form of dies 11a-11c is swaged from three direction s simultaneously so as to be finished corresponding to the size of the work hole 13.
