PROBLEM TO BE SOLVED: To provide a manufacturing method for a gas sensor capable of reducing a manufacturing cost by simplifying a working process and a working installation therefor. SOLUTION: In manufacturing an oxygen sensor 1, a rear end part of a principal fitting 7 is caulked by a two-spindle type press P with a filler member 5 pressurized. This eliminates the problem of buckling the once compressed filler member 5. As a result, heat caulking so far performed for buckling correction is not required and the omission of the heat caulking dispenses with a power supply, a cooling device, or the like, needed therefor. Resultantly, the whole of a manufacturing device can be simply constructed and the manufacturing cost for the oxygen sensor 1 can be reduced as a whole. |
