ナツトｄにより締付け、固定されている。Prior Art In Figs. 3 and 4, there is a terminal bolt b protruding from a part a that is directly attached to an engine such as an automobile alternator, and a terminal A with an electric wire c crimped to an electric wire connection portion A1 is an electric contact portion thereof. The terminal bolt b is inserted into the hole A3 of A2 and connected to the bolt b,
It is tightened and fixed with nut d.

方向には回転しないで、端子用ボルトｂと一緒に
ゆるむ方向にのみ回つてしまう欠点を有する。 However, in such conventional technology, when there is engine vibration e, terminal bolt b, terminal A, and nut d vibrate together, but electric wire c is connected to terminal A. Therefore, the terminal A does not vibrate in the same direction and the terminal bolt B
Rotational torque acts around , and in this case the nut d is tightened, so it has the disadvantage that it does not rotate in the direction of further tightening, but only in the direction of loosening together with the terminal bolt b.

る。Effects of the invention As described above, the present invention provides a substantially regular polygonal coupling hole in the electrical contact part of a terminal having a wire connection part and an electrical contact part, and engages the coupling hole in the base of the terminal bolt. A substantially regular polygonal anti-rotation protrusion is provided,
Since the electrical contact part is directly pressurized by the nut, the anti-rotation protrusion prevents the terminal from rotating even during vibrations, preventing the nut from loosening, thereby preventing poor contact of the terminal. Since the locking protrusion and the engaging hole of the terminal are connected in a substantially regular polygonal shape, the position at which the electric wire is drawn out from the terminal can be easily changed.
