Abstract
An electrode unit configuring a resistance welding device is provided with a first chassis section and a second chassis section. A plurality of stepped hole sections are formed in the first chassis section, and an electrode pin is slidably provided in each stepped hole section. On the head section of the electrode pin, a resin ball configuring a welding pressure adjusting mechanism is disposed. In the second chassis section, a screw hole is formed coaxially with each stepped hole section, and a setscrew configuring an extrusion output adjusting mechanism for adjusting an extrusion output of the electrode pin is screwed into each screw hole.
