PURPOSE:To prevent surely a bushing from dropping-out and rotation by easily press fitting an outer tube formed with only an engaging part formed of a recess or opening into a metal bracket and then projecting and deforming a portion of the metal bracket in the engaging part. CONSTITUTION:An outer tube 2 is press fitted in a cylindrical metal bracket 4 with a thick wall. The central portion of the peripheral surface of the outer tube 2 is caved inward in the rectangular form on the upper and lower opposed portions to form recesses 21 as engaging parts. The metal bracket 4 is bulged inward on the portions 41 thereof corresponding to these recesses 21 and entering engageably the recesses. That is, an inner tube 1 is disposed in the center of the outer tube 2 formed on the peripheral surface with the recess 21 and a vibration preventing rubber body 3 is provided integrally between these inner and outer tubes 1, 2 by injection molding. Such an outer tube 2 is press fitted and located in the metal bracket 4 which is not yet formed with the bulging portions 41. Then, the portions 41 of the metal bracket corresponding to the recesses 21 of the outer tube 2 are bulged and deformed inward by a press or the like to provide bulging portions. |
