PURPOSE:To provide possiblity of feeding a wire surely straight in the axial direction by permitting a cover, mounted on a holding member with possiblity of relative movement, to press a retainer, putting the roller in pressure contact with the wire, and thereby maintaining the shaft of roller in a desired position of tilting. CONSTITUTION:The body 1 of this arrangement 1 is equipped with a holding member 2, hollow shafts 6, 7 installed projectingly at the inlet and outlet for wires, etc. where the holding member 2 is mounted on hollow shaft 9 of a motor with the aid of a cramp 8 provided at the end of said hollow shaft 6. At this time, the square drum part 5 between two flanges 3, 4 is excavated with hole 13 in the direction perpendicular to the axis 12 of wire, and retainers 14a, 14b are set in this hole slidably to bear the shafts 16 of rollers 15 with their both ends. A cover is installed, and the internal surfaces of its cylindrical part 26 are fitted at the flanges 3, 4 rotatably while the sleeve part 27 is fitted on the hollow shaft 7 also rotatably. The roller 15 is put in pressure contact with the wire by permitting the cover 25 to press the retainer 14 so as to ensure straight feeding of the wire. |
