CAULKING COUPLING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To improve strength of caulking coupling. SOLUTION: The base part of an L-shaped metal bracket 3 having a mounting screw hole 2 in the center of a side protruding part 1 is fixed by welding at a place where both one edge of the side of metal cylinder 5 (solenoid component) and one edge of the side protruding part 1 are set on the same level. In the caulking coupling structure that other component part 6 (sleeve) is coupled with the cylinder 5 having one edge caulked, both sides of side protruding part 1 near the base part 4 are formed in recessed condition toward the base part 4. In other parts than that adjacent to the central part, one edge of the cylinder 5 including the adjacent part to the recessed part 7 is caulked to form a caulking coupling part 8 which is caulking coupling structure.
