The protrusion 111 has a semicircular shape that is convex upward when viewed from the left and right sides, and has a predetermined width in the left and right directions when viewed from the front or the upper side.

Therefore, at the upper end of the plug housing 110, the front, upper and rear surfaces having a predetermined thickness are connected in a rounded curved surface, and the upper cutout 112 is formed at the center thereof.

The upper cutout 112 extends in the front-rear direction when the plug housing 110 is viewed from the top, and extends further downward from the front side of the plug housing 110 in the downward direction, and thus will be described later. It extends to the bottom height of the receiving portion 113.

The shaft accommodating part 113 is formed by penetrating the left and right sides near the upper end of the plug housing 110 from side to side. That is, the shaft receiving portion 113 is provided with a pair facing each other. The shaft receiving portion 113 is formed in a circular shape.

Therefore, when looking near the upper end of the housing 110 from the left and right side, a convex semicircular protrusion 111 is provided to the upper side, a through hole is formed in the inner side, the through hole is the shaft receiving portion 113. .

The shaft member 120 is coupled to the shaft receiving portion 113 of the plug housing 110. The shaft member 120 includes a first shaft member 121 that extends from side to side and a second shaft member 122 screwed with the first shaft member.

The first shaft member 121 includes a substantially cylindrical first body 121a and a substantially plate-shaped first plate portion 121b coupled to an outer end of the first body 121a. The first body 121a has a diameter approximately equal to or slightly smaller than the shaft accommodating portion 113, and the first plate portion 121b has a larger diameter than the shaft accommodating portion 113. In the present embodiment, the first plate portion 121b has a disc shape, but may have a quadrangle or other shape.

An intermediate cutout 121c is formed in the first body 121a perpendicular to the extending direction. The intermediate cutout 121c has only a part of the first body 121a left as shown in FIG. 3. It is formed by removing in a disk shape having a predetermined thickness. The part left here is called the connection part 121d. Accordingly, the first body 121a has a shape in which two members are integrally coupled to the connection portion 121d. The connecting portion 121d may be formed as a curved surface having an outer circumferential surface.

Here, the intermediate cutout 121c becomes a portion through which the cable 150 passes.
