Claims

[Scope of Claim for Utility Model Registration] (1) A fixing plate for fixing the thickness adjustment plates stacked on both sides of a welding electrode is fixed to both sides of the electrode by fastening means, and the outer side of the fixing plate is Welding characterized in that the screw rod is made to protrude to opposite sides, and a washer having a chamfered portion on the side facing the electrode is externally fitted between a stopper at the tip of the screw rod via an elastic body. machine electrode. (2) A convex edge of a recess with an inner dimension corresponding to the outer dimension between the outer surfaces of the fixed plate fixed to the electrode has an opening on the end surface side of the convex edge, and the male threaded rod is fitted into the convex edge of the concave. What is claimed is: 1. An electrode holder for a welding machine, characterized in that the electrode holder is provided with a notch into which the washer is inserted, and a bulge having a tapered surface on the opening side of the outer surface of the bulge with which the chamfer of the washer comes into contact.
