Zusammenfassung:	To provide a resistance-welding device configured so that a cover member can be stably expanded and contracted.SOLUTION: A welding gun 10 comprises an approach-suppressing mechanism 40, provided between a shaft 26 and a cover member 32 to surround the shaft 26 and to be relatively movable in a shaft direction with respect to the shaft 26 accompanying expansion and retraction of the cover member 32, which suppresses the cover member 32 from approaching the shaft 26 too closely.SELECTED DRAWING: Figure 3 【課題】カバー部材を安定して伸縮させることができる抵抗溶接装置を提供する。【解決手段】溶接ガン１０は、シャフト２６とカバー部材３２との間に、シャフト２６を取り囲むように、且つ、カバー部材３２の伸縮に伴ってシャフト２６に対して軸方向に相対的に変位可能に設けられ、カバー部材３２がシャフト２６に接近し過ぎることを抑制する接近抑制機構４０を備えている。【選択図】図３
