<p><P>PROBLEM TO BE SOLVED: To obtain a flat cable winding/feeding unit having a reduced thickness. <P>SOLUTION: The flat cable winding/feeding unit comprises a case 12 having an annular space S, a rotor 14 provided rotatably in the case, a coil spring 16 imparting a rotating force to the rotor, and a flat cable 10 having one end connected to a fixed body and the other end connected to a moving body. The rotor 14 comprises a roll 36 for reversing the winding direction of the flat cable 10 in the annular space S, a guide roll 38 for guiding the flat cable 10 along the inner circumferential surface of the outer annular wall 18, and a hollow shaft 40 fitted rotatably to the inner circumference of the inner annular wall 20. The coil spring 16 is arranged coaxially in the hollow shaft 40 of the rotor 14 and engaging, on one end side 16a thereof, with the hollow shaft 40, and on the other end side 16b thereof, with a lower case 12B while being twisted to impart a rotating force to the rotor 14 in the winding direction of the flat cable 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
