WELDING CHUCK AND WELDING MACHINE

To provide a welding chuck which enables reduction of the number of components with a structure simpler than that of a conventional jig and also enables improvement of maintainability.SOLUTION: A welding chuck 2 includes: base end fixing parts 21 fixed to an opening/closing mechanism; tip holding parts 22 which hold multiple terminals 31, 31 in a sandwiching manner; elastic extending parts 23 extending in a longitudinal direction (a Z axis direction) along a protruding direction of the terminals 31, 31 between the base end fixing parts 21 and the tip holding parts 22; and split grooves 24 each of which extends along the longitudinal direction from a tip of the tip holding part 22 to the base end fixing part 21.SELECTED DRAWING: Figure 3 【課題】本開示は、従来の治具よりも単純な構造で部品点数の削減が可能であり、メンテナンス性を向上させることが可能な溶接チャックを提供する。【解決手段】溶接チャック２は、開閉機構に固定される基端固定部２１と、複数の端子３１，３１を挟み込んで保持する先端保持部２２と、基端固定部２１と先端保持部２２との間で複数の端子３１，３１の突出方向に沿う長手方向（Ｚ軸方向）に延びる弾性延在部２３と、先端保持部２２の先端から基端固定部２１へ向けて長手方向に沿って延びる分割溝２４と、を有する。【選択図】図３
