Abstract
The present invention provides a press-fit joining apparatuswhere two collet-chuck-type electrodes (first collet-chuck-type electrodeand second collet-chuck-type electrode) are held using a die set structural bodyand a sub platen structural body. According to the press-fit joining apparatusof the present invention, it is possible to manufacture a product which is required to have higher coaxiality and higher joining strength than conventional products (for example, products such as a drive force transmitting part, the manufacture of which requires the supply of a large and uniform electric current to a joining portion).
