PURPOSE:To press fit an inner ring inserted into and retained by a press fitting body easily into a pipe material by providing a screw shaft-shaped press fitting operation body screwed to a device main body and a revolving body-shaped press fitting action body installed revolvably at the end of the press fitting operation body and screwing the press fitting operation body. CONSTITUTION:An inner ring 2 of a press fitting action body 2 is inserted and retained in an inner ring retaining section 22 of a press fitting body 5, and a section close to an end of a PFA pipe 1 is fixed to a clamp bed 9. The inner ring 2 is press fitted into the PFA pipe 1 by revolving a press fitting operation body 4 by means of an operation handle 19 and screwing forward. At that time, the force fitting action body 5 retaining the inner ring 2 is revolvably on the press fitting operation body 4, and the press fitting operation body 5 is made of tetrafluoroethylene resin with small frictional resistance, and the inner ring 2 is press fitted in the stabilized posture the god press fitting accuracy without relatively revolving to the PFA pipe 1, despite of the revolution of the press fitting operation body 4. |
