PROBLEM TO BE SOLVED: To enable a vibration-proof rubber to be easily fitted to a hanger of a vibrohammer.SOLUTION: A vibrohammer vibration-proof rubber fitting tool comprises a bolt 165 and a special nut 170. The bolt 165 has a slender tip 167. The special nut 170 comprises: a nut upper part 171, which has a cross section with a larger external diameter than that of a hole 154 in a predetermined shape formed on a metal plate 151; and a nut lower part 172 with a cross section, the external diameter of which has the same shape as that of the hole 154 in the predetermined shape and is smaller than an inner diameter of the hole 154 in the predetermined shape. A spiral open hole 173 penetrates the nut upper part 171 and the nut lower part 172. When the metal plate 151 is fitted to an inside surface of a hanger 110, the tip 167 of the bolt 165 engages to the spiral open hole 173.SELECTED DRAWING: Figure 12 |
