The rubber bush is one of the key components of the vehicle shock absorber. It connects the shock absorber to the vehicle and absorbs external vibration and shock. Generally, a rubber bush for a shock absorber of a vehicle is provided with an inner bush, an outer bush, and a rubber which is bonded between the inner bush and the outer bush to serve as a vibration proof. The inner bush is fastened to the vehicle through bolt insertion when the shock absorber is mounted, and the outer bush is pressed into the shock absorber to catch the rubber from the shock absorber. In recent years, rubber bushes having improved shock absorber assemblability have been developed and used by attaching a guide ring serving as a guide when assembling a vehicle. A rubber bush having a guide ring is conventionally manufactured in the following manner. First, after the swaging process operator places the swaging device on the swaging device, the swaging device is operated to perform the swaging process. Thereafter, the operator removes the rubber bush from the swaging device. Next, after the indentation / caulking process operator places the rubber bush detached from the guide ring and the swaging device on the press-fit / caulking device, the press-in / caulking device is operated to firmly fix the guide ring to the rubber bush. Thereafter, the indentation / calking process operator removes the rubber bush with the guide ring from the indentation / calking process device. However, in the process of manufacturing the rubber bush having such a conventional guide ring, defects due to the number of worker errors (for example, lack of swinging operation missing guide and reverse assembly of guide ring) occur, .
