PURPOSE:To improve working efficiency by making it easy to remove a wire reel from a turntable without being influenced by wire reel deformation caused by wire winding. CONSTITUTION:A bolt 32 is formed into a stepped structure having a stepped part 32E thereon and secured by tightening it so that tightening force of the bolt 32 is applied only between a flange 30 of the turntable 20 and a flange 42 on the turntable 20 side of a wire reel 36, while respective fitting parts 30A, 42A are matched by tapering. Thus tensile force does not work on the bolt 32 in the axial direction even if elongation force acts on the wire reel 36 in the longitudinal direction by winding the wire 10 to the wire reel 36. Furthermore mutual chamfering of fitting parts 30A, 42A do not take place even if the wire reel 36 deforms. Thus the wire reel 36 can be simply removed from the turntable 20. |
