<P>PROBLEM TO BE SOLVED: To prevent the early wearing of a flexible printed wiring board (FPC board) when configuring a rotary joint wiring unit for a robot using the FPC. <P>SOLUTION: A wiring case 13 is configured by combining a casing 15 connected to one of members of a robot with a reel 20 rotatable relatively to the casing 15 and connected to the other member rotated relatively to the one member. In the wiring case 13, an annular slide aid 23 having both ends in which a plurality of rollers 25 are arranged is disposed rotatably around the core member 16 of the reel 20. A FPC board 14 housed in the wiring case 13 is connected to the core member 16 at one end side and connected to the casing 15 at the other end side. A part located inside the slide aid 23 is wound along the inner periphery of the slide aid 23. A part drawn out from both ends of the slide aid 23 to the outside of the slide aid 23 is wound around the outside of the slide aid 23 in such a way that its winding direction is reverse to that inside the slide aid 23. <P>COPYRIGHT: (C)2013,JPO&INPIT |
