中心線)(z+)と一致していれば、何ら問題なく溶接
を行える。(Problem to be Solved by the Invention) When the above-mentioned welding gun penetrates into the welded parts of the joint parts (8) and (9), it is usually necessary to connect the pivots (3) of the gun arms (1) and (2) and the welding electrode ) (5) and the center line (
! The spot welding gun is moved in parallel along I) to penetrate. Therefore, the extension line (12) of the mating surfaces of the end faces of the joining members (8) and (9) is the direction of penetration of the spot welding gun (
If it matches the center line) (z+), welding can be performed without any problem.

ができず、溶接を行えなかった。However, as shown in FIGS. 8 and 9, the connecting parts (10
) If the direction of the mating surface (12) in (11) intersects the direction of penetration of the spot welding gun (!I), or if the joining parts (
12) At least one end (12a) of (13)
If the gun arm (1) (2) of the spot welding gun is bent and exceeds the opening of the spot welding gun,
is the connecting member (1o) (11) or (12) (13
), the welding gun could not penetrate into the area to be welded, and welding could not be performed.

ず、ロボット等に対する負荷も少なく、安全である。According to this invention, the direction of the gun arm 1 can be adjusted by moving the collar shaft and holding the eccentric shaft formed therein at the rear of the gun arm, thereby rotating the gun arm around the pivot shaft. This allows you to change the direction of the gun arm without installing a special rotation mechanism on the robot or automatic machine that holds the spot welding gun, making it possible to use the spot welding gun on inclined joint parts or joint parts with flanges. They can be invaded, and inexpensive robots can be used. Further, since the present invention only adds a few parts to the conventional spot welding gun, the Ti angle does not increase, the load on robots, etc. is small, and it is safe.
