(Prior Art) Electric wires originally have a circular cross section. However, it has recently been discovered that the cause of wind noise and wind pressure vibration is that the cross-sectional shape of the electric wire is circular. In other words, it has been found that vibration is generated by the separation of air fluid flowing around the outer circumference of a circular wire, and is the source of wind noise and wire vibration.In order to reduce noise and vibration, the wire's outer shape should be I found out that it's better if it's not circular.

(Solution by invention) U-shaped grooves with a constant pitch are arranged in parallel in the width direction of a gripping collar that has a single or multiple protrusions and is wrapped around a gripping portion of an electric wire that has a circular cross section except for the protrusions. Further, a protrusion groove into which the protrusion of the electric wire fits was obliquely provided on the side where the U-shaped groove was provided. After wrapping this gripping collar around the gripping portion, the gripping member is tightened.

This is an electric wire 1 having a single or multiple protrusions 2.
The protrusion 2 is placed on the outer peripheral surface of the part excluding the protrusion 2.
An armor rod 3 having a diameter d larger than a height h of the armor rod 3 is wound around the armor rod 3, and a gripping member 4 is attached onto the armor rod 3 to clamp it.

Now, the present invention can be said to be an improvement on the above-mentioned invention, and when the electric wire 1 having the protruding part 2 is gripped by the gripping member 4, a gripping rod that is wound around the gripping part is used instead of an armor rod which has problems in terms of workability. It is characterized by its color.

The explanation will be given below based on FIGS. 1 and 2. 5 is a rectangular, thin metal gripping collar (hereinafter referred to as collar). Reference numeral 6 denotes U-shaped grooves arranged in parallel at a constant pitch in the width direction of the collar 5. Reference numeral 7 denotes a protrusion groove provided diagonally in the center of the collar 5 on the side where the U-shaped groove 6 is provided, into which the electric wire protrusion 2 (see FIG. 3) is inserted. The depth d 1 of the groove 7 is smaller than the depth d of the U-shaped groove 6 .
