く寄与している。What is important here is that the position of the torsion coil spring 16 for return is determined by the terminal fitting 6 as is apparent from FIG.
Is located behind the position where the screw hole is provided. Therefore, the locking point between the return torsion coil spring 16 provided on the washer guide portion 13 becomes closer to the washer 12, and
The longitudinal dimension of the washer guide portion 13 is reduced. By the way, in the conventional example shown in FIG.
0, and the washer guide portion 42 is supported by penetrating the terminal fitting 41 even when the terminal screw 40 is farthest from the terminal fitting 41. Is getting longer. Another important point is that the ridge direction of the bend of the washer 12 and the washer guide portion 13 is perpendicular to the axial direction of the torsion coil spring 16 for return. Incidentally, in the conventional example shown in FIG. 3, these two directions are parallel to each other. These features of the present invention greatly contribute to the reduction of the depth length of the entire terminal device.
