になされている。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. (3) is a terminal screw, and (7) and (8) are a spring washer and an electric wire press washer attached to the neck of the terminal screw. Notches (4) are formed at the center of four sides of the electric wire press washer (8). 81) and (82) are provided. Then, ribs (51) (52) are provided on the inner wall surface of the operation hole (5) corresponding to the notches (81) (82) of the electric wire press washer (8),
Fitting the rib (51) into the notch (81) and the rib (52) into the notch (82) of the electric wire press washer (8), the electric wire press washer (8) was dropped into the operation hole (5). At this time, the washer (8) can freely move back and forth in the depth direction of the operation hole (5).

防止するために操作穴（５）を充分に深くして安全性を
高めることもできる。Since it is configured as described above, when the electric wire press washer (8) integrated with the terminal screw (3) is inserted into the operation hole (5) through the opening of the operation hole (5), the wire is shown in FIG. As shown, the electric wire press washer (8) is prevented from rolling in the Y direction by the abutting engagement between the rib (51) and the notch (81), and the electric wire press washer (8) shown in FIG. Ribs (52) for turning in the Y direction
It is prevented by the abutting engagement of the notch (82). That is, the wire press washer (8) does not rotate in either X or Y direction,
It slides only in the depth direction of the operation hole (5). Therefore, even if the terminal screw (3) integrally combined with the wire retainer washer (8) is disengaged from the terminal fitting (2), the wire retainer washer (8) is almost connected to the terminal fitting (2). 〞Because it moves back and forth while maintaining the parallel relationship, the terminal screw (3) does not fall over in the operation hole (5) unlike the conventional one, and the driver screw tip is engaged with the head of the terminal screw (3). Alternatively, the tip of the terminal screw (3) can be easily seen through the screw hole of the terminal fitting (2), which makes the connection work very easy. Also, since the workability of the above-mentioned wiring work is not affected by the depth of the operation hole (5) at all, the operation hole (5) should be deep enough to prevent an electric shock accident for safety. It can also be increased.

（８）として円形のものを用いてもよい。In addition, in the above-mentioned embodiment, one rib is provided on each of the three wall surfaces of the operation hole (5), and three ribs are provided for convenience. However, as shown in FIG. One rib may be provided on each of the two sides orthogonal to each other, that is, two ribs for convenience, and a circular wire press washer (8) may be used as shown in FIG.
