Title:
RESISTANCE WELDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/058853
Kind Code:
A1
Abstract:
This resistance welding device (1) welds a bracket (first member) (2) and an outer tube (second member) (3) by bringing same into contact, applying pressure in a direction in which same approach each other, and flowing current between same. The resistance welding device (1) is provided with a first electrode (10), a second electrode (20), and a first holding member (30). The first electrode (10) is in contact with the bracket (2) while being pressed against the bracket (2). The second electrode (20) is disposed so as to oppose the first electrode (10) and is in contact with the outer tube (3). The first holding member (30) has a first V shaped surface (first holding surface) (34) for holding the bracket (2), and the bracket (2) is pressed toward the outer tube (3) via the first V shaped surface (34). The first holding member (30) has electrical insulating properties with respect to the first electrode (10). In the first holding member (30), the first electrode (10) is inserted in freely slidable fashion in a through hole (33) that is open on the first V shaped surface (34) side.
