して上記の問題を解決するかが課題となる。However, in any of the conventional electric pressurizing devices for spot welding guns, the electrode pressurizing mechanism is not unitized. In general, components such as a ball nut, a ball screw and a rotation stopper, and a transmission mechanism such as a driving belt and a belt gear are incorporated in the main body. Therefore, it is difficult to assemble and adjust (the tension of the driving belt). Also, since mass production is difficult, production costs are high. In addition, it takes time to perform maintenance and determine the accuracy of the core (especially replacement of driving parts), resulting in high maintenance costs. Therefore, regardless of the variation of the gun body, it is an issue how to make the electrode pressing mechanism such as an electric motor or a ball screw compact and unitized to solve the above problem.
