Claims

[Claims for Utility Model Registration] (1) A seam welding machine that guides an annular welded part of a workpiece that is integrally moved by a copying plate that is rotatably provided in a direction along a surface between a pair of upper and lower roller electrodes. A copying device includes: a workpiece support that runs integrally with the copying plate above the copying plate and is swingable around an axis parallel to the copying plate surface; A copying device for a seam welding machine, comprising: a work holder that clamps a workpiece between the workpiece holder and the workpiece holder by swinging to follow the oscillation of the workpiece on the workpiece holder; (2) The copying device for a seam welding machine according to claim 1, further comprising an actuator connected to the workpiece receiver and maintaining the workpiece receiver in a predetermined state. (3) The copying device for a seam welding machine according to claim 2, wherein the actuator switches the biasing direction to the workpiece holder to swing the workpiece holder based on a detection signal of a starting point of the swinging of the workpiece holder. .
