An object of the present invention is to straighten a wire such that twisting of the wire does not accumulate to prevent tangling of the wire when the wire is unwound from a bobbin installed in a horizontal state while gyrating. A roller supporting portion supports rotating shaft portions of a pair of rollers in a state in which a wire is sandwiched between the pair of rollers, which are rotated by following a movement of the wire, at an intermediate position that is midway in a transfer path of the wire, which is unwound from a bobbin while gyrating, and in a state in which rotation axes of the pair of rollers are kept at skew positions that are parallel with each other when viewed in a transfer direction of the wire at the intermediate position. |
