バー。 In a back bar of a vertical automatic welding device equipped with a lifting/lowering and forward/backward movement mechanism, a fixed part having a sliding surface with an upward slope from the front side to the rear side of the back bar provided at either or both of the upper and lower ends of the back bar; , a movable body that is movable along the sliding surface via a reciprocating linear movement means and always biased toward the front side of the back bar via a return means; and a movable body that returns to the front of the movable body in the extension direction of the back bar. The movable part back bar is provided with a split back bar that is located forward of the front surface of the back bar and has a back gas communication path for avoiding an inwardly bent part of the workpiece, the tip of which protrudes from the end of the movable body. Features a movable back bar.
