た構造である。2. Description of the Related Art FIG. 4 shows a conventional terminal fitting 21 of a rubber stopper mounting type. The terminal fitting 21 has an electric contact portion 23 in front of a substrate 22 and a type in which a rubber plug 25 and an electric wire 26 are simultaneously caulked to an electric wire connecting portion 24 on the rear side. Several types of wires 26 of different sizes

The reference of the bottom wall Gb insulator crimping piece 24b is because using a wire 26 1, 26 2, 26 3 of different sizes while fixing, the crimping pieces 24a, the crimp height of 24b vary by size. For example, if the standard electric wire for the terminal fitting 21 is the electric wire 26 2 , and 1/2 of the crimp height is h, the small-diameter electric wire 26 1 is as low as h 1 and the large-diameter electric wire 26
In 3 as high as h 3. As a result, the center line (axis) of the terminal fitting 21 does not coincide with the center of the rubber plug 25.

And the center of the rubber stopper 25 is shifted. For this reason, the pressing force of the rubber stopper 25 against the upper surface and the lower surface of the inner wall of the storage portion becomes uneven, and the electric wire 26
It becomes impossible to obtain a uniform sealing property against runout. In the above, the terminal fitting 21 is of a female type, and the electrical contact portion 23 has a cylindrical receiving portion 23a for receiving a mating terminal, and an elastic tongue 23b folded back from the substrate 22 into the receiving portion. However, the same applies to the case where a rubber stopper is attached to the male terminal fitting 21 'shown in FIG.
