Description of the Related Art Conventionally, as a connector device used for a steering device for a vehicle, the applicant of the present application has one end fixed to a rotating member 35 and the other end outside the rotating member 35 as shown in FIG. A flat cable (flexible cable) 37 fixed to a fixing member (fixed shaft) 36 in the rotating member 3
5 and the fixed shaft 36 are wound a plurality of times around both the rotary member 35, the fixed shaft 36 and the flat cable 37.
The first application was for a connector device that is housed in No. 8 (Japanese Patent Laid-Open No. 6-243946).

The flat cable 7 is unwound from the winding member 1. Here, the flat cable 7 is wound around the winding member 1, and the winding auxiliary member 2 is thereby rotated, so that the spiral spring 5 in the winding auxiliary member 2 is wound around the winding core 3. Since its end 5'is engaged and fixed to the slit 4a, it is not pulled out to the outside of the winding auxiliary member 2 and a sufficient elastic force (restoring force) is generated in the counterclockwise direction.

められていくことになる。Therefore, when the flat cable 7 is unwound from the winding member 1, the counterclockwise elastic force generated by the spiral spring 5 causes the winding assisting member 2 to move in the second case defined by the protrusion 10a. It is rotated counterclockwise at a predetermined position of 10. At this time, when the flat cable 7 is tightly wound around the winding member 1, a frictional force due to contact with the spiral spring 5 acts on the flat cable 7c in the winding auxiliary member 2, and the winding auxiliary member 2
Since it is not pulled out to the outside, the amount of rotation of the winding assisting member 2 can be kept constant, and the flat cable 7 fed into the second case 10 via the cable passage 12 can assist the winding. The flat cable 7c and the spiral spring 5 in the winding auxiliary member 2 are wound around the member 2 and stored in the second case 10.
2 is gradually loosened from the winding core 3 as shown in FIG.
