Patent ID: 7740199

Claim:
A metallic filament end retaining clip mountable on a take-up reel for metallic filament provided with a flange made of a metallic plate on both sides of a winding drum that has a hollow ring-shaped flange outer periphery portion curling outward in the axial direction of the reel across the entire circumference of an outer edge, forming a space between the flange outer periphery portion and a flange outer surface, the metallic filament end retaining clip being mountable in a removable state in the space between the flange outer periphery portion and the flange outer surface, wherein a clip portion, formed from an elastic wire, is bent in an essentially W shape when viewed from the front, and attachment arm portions that extend the upper ends of the W shape in an essentially horizontal direction are formed on both sides of the clip portion; guide portions for capturing the end part of the metallic filament are configured by slanting the vicinity of lower curved portions on both sides of the clip portion forward, as viewed from the side, at a first angle relative to the upper portion and middle portion of a part that forms an inverse V when the center of the clip portion is viewed from the front; the upper portion of the clip portion, excluding the guide portions, of the outer wire portions of essentially V shapes on either side when viewed from the front, is, in its free state, slanted forward at a second angle relative to the guide portions when viewed from the side, the second angle being greater than the first angle, and coiled portions are formed in the vicinity of the upper ends of the outer wire portions; the attachment arm portions are, in their free states, angled forward relative to a line that connects the upper ends of the W shape of the clip portion, and the tip sides of the attachment arm portions are bent even further forward; and the top bent portions in the center of the clip portion are positioned higher than the line that connects the upper ends of the W shape of the clip portion.
