PURPOSE:To reduce an impact force acting on a metallic thin wire by means of a clamper and, at the same time, to simplify the adjusting work of the clamper. CONSTITUTION:A clamper 25 is formed of a disk 26 for holding provided with a groove 26a having a round bottom and stopper 28 which presses a metallic thin wire 2 against the groove 26a. The pressing section 28a of the stopper 28 is formed into a circular-arc shape along the disk 26. Since the groove 26a has the round bottom, the contact area of the thin wire 2 becomes larger and the wire 2 can be held firmly with a weak force. Since the thin wire 2 is shifted to the central part of the groove 26a in the width direction when the wire 2 is held, no high accuracy is required for adjusting the stopper 28. |
