In this example, the flat cable 12 has four conductors 15, and these conductors 15 are, for example, a power supply line, a ground line, a signal line, and the like.

FIG. 4 is a perspective view of a shaft body and a movable body constituting the winding device. FIG. 5 is a side view of the shaft body and the movable body constituting the winding device.
As shown in FIGS. 4 and 5, the shaft body 40 is formed in a columnar shape and is erected at the center of the case 20. The shaft body 40 has a plurality of annular contacts 41. The annular contacts 41 are arranged in the axial direction of the shaft body 40. The annular contacts 41 are respectively fitted into a plurality of annular grooves 42 formed in the shaft body 40 over the circumferential direction. The shaft body 40 is provided with a terminal (not shown) at its upper end. These terminals are electrically connected to each annular contact 41 via an internal conductor (not shown) made of an electric wire or the like provided inside the shaft body 40. Moreover, the connector 8 provided in the electric wire 7 of the wire harness by the side of the vehicle body 2 is connected to these terminals. Thereby, the connector 8 is connected to the upper end of the shaft body 40, whereby each annular contact 41 is electrically connected to each wire 7 of the wire harness on the vehicle body 2 side.

FIG. 6 is a perspective view of the movable body.
As shown in FIG. 6, the movable body 50 has a sliding contact surface 51 that is in sliding contact with the outer peripheral surface of the shaft body 40, and a plurality of sliding contacts 52 are provided on the sliding contact surface 51. . The movable body 50 is disposed on the outer peripheral side of the shaft body 40. The movable body 50 is movably supported so as to revolve around the shaft body 40 along the outer periphery of the shaft body 40. Each of the sliding contacts 52 is formed in, for example, a hemispherical shape, and a hemispherical top portion slightly protrudes from the sliding contact surface 51. The sliding contacts 52 are arranged at the same intervals as the intervals between the annular contacts 41 of the shaft body 40. Accordingly, each of the sliding contacts 52 is in contact with and in contact with the annular contact 41. One end of the flat cable 12 is connected to the movable body 50, and each conductor 15 of the flat cable 12 is electrically connected to each sliding contact 52.

A cylindrical wall 61 is erected on the rotating plate 60, and the movable body 50 is disposed on the inner peripheral side of the cylindrical wall 61. A slit 62 is formed in the cylindrical wall 61 along the axial direction, and the flat cable 12 connected to the movable body 50 is passed through the slit 62. The flat cable 12 passed through the slit 62 of the cylindrical wall 61 is wound around the outer peripheral side of the cylindrical wall 61 and drawn out from the cable lead-out path 30 to the outside.

  On the lower surface side of the rotating plate 60, a spring (not shown) that is an urging member for rotating the rotating plate 60 is provided. The rotating plate 60 is rotated by the urging force of the spring spring, so that the movable body 50 moves around the shaft body 40 in one direction of rotation. Specifically, the spring spring moves the movable body 50 in the rotation direction in which the flat cable 12 drawn from the cable lead-out path 30 is drawn into the case 20.

  7A and 7B are diagrams for explaining the movement of the winding device. FIG. 7A is a plan view of the winding device in which the flat cable is wound and the cover is removed, and FIG. 7B is a flat cable.

  In the winding device 10 having the above structure, as shown in FIG. 7A, when the slide sheet 1 is slid in one direction from the state in which the flat cable 12 is wound in the case 20, FIG. As shown, the flat cable 12 is pulled out from the cable lead-out path 30 as the slide sheet 1 slides. Then, the movable body 50 to which the flat cable 12 is connected revolves around the shaft body 40, whereby a rotational force in the reverse direction is applied to the movable body 50 by the biasing force of the mainspring spring. In this state, when the slide sheet 1 is slid in the other direction, the movable body 50 is rotated in the reverse direction by the urging force of the mainspring, so that the flat cable 12 that has been drawn out is moved from the cable lead-out path 30 into the case 20. Drawn into.
