Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reliably weld a fixed metal fitting 23 of a support member 2 and a sealed case 3 to a valve housing 1 without welding failure, in a motor valve 100 where the support member 2 and the sealed case 3 are assembled to the valve housing 1.SOLUTION: On the whole circumference of an opening end part of a valve housing 1, a step part 11 is provided. The step part 11 comprises an inside first annular surface 11a and an outside second annular surface 11b. A fixed metal fitting 23 is arranged inside the second annular surface 11b, and the first annular surface 11a is contacted with a flange part 232. The whole circumference of a contact portion between the first annular surface 11a and the flange part 232 is welded. An opening end part of a lower end of a sealed case 3 is contacted with the second annular surface 11b. The whole circumference of a contact portion between the second annular surface 11b and the opening end part of the sealed case 3 is welded.
