Ž<P>SOLUTION: An ended annular sliding auxiliary tool 23 with a plurality of rollers 25 is arranged so as to be circularly movable around a core member 16 of a reel in a wiring case formed by relatively rotatably combining a cylindrical case 15 with the reel. The flexible printed wiring board (FPC board) 14 is stored in the wiring case so as to wind the core member 16 inside the sliding auxiliary tool 23 and is stored so as to wind the outside of the sliding auxiliary tool 23 outside the sliding auxiliary tool 23. The one end side of the FPC board 14 is coupled to the core member 16, and the other end side thereof is coupled to the case 15. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž</p> |
