Patent ID: 7891599

Claim:
A take-up reel for metallic filament having a flange at both ends of a winding drum, the reel comprising: a recessed portion in at least one area in an inside surface of a flange, the recessed portion extending in a radial direction toward a flange outer edge; and a connecting portion that straddles the recessed portion in a circumferential direction extending only partway along the recessed portion, thereby connecting the inside surface of the flange on both sides of the recessed portion, wherein the connecting portion is flush with the inside surface of the flange on both sides of the recessed portion, and wherein a tabular end retaining member having elasticity is fitted into the recessed portion, with a base end portion of the end retaining member being passed under the connecting portion and brought into contact with an inside surface of the recessed portion on a side of the connecting portion closer to a winding drum side and out of the connecting portion and butted up against an end surface of the recessed portion on the winding drum side, and with enough space provided between a tip end portion of the end retaining member and the flange outer edge to allow an end part of the metallic filament to be caught therein, and an area around the base end portion is anchored to the connecting portion.
