  In the wire harness connection structure described in Patent Document 1, a case 110 having an extra length absorbing function and a sheet side fixing portion 202 for fixing the wire harness 200 drawn from the case 110 to the sheet are separated on the back side of the sheet. Since it is provided at the position, it is necessary to individually fix these to the seat, and there is a problem that the assembling workability to the vehicle is poor. The extra length absorbing case 110 requires a main body, a lid, a spring accommodated in the case, and a circular guide, and there is a problem that the number of parts is large and the cost is high. Furthermore, since the wire harness is simply wired in the U shape in the case 110 to absorb the surplus length, it is necessary to increase the length of the case 110 to increase the size of the slide sheet when the moving length of the slide sheet increases. There is a problem that the installation space becomes large.

  Further, it is understood that the vehicle body side fixing portion 201 on the floor of the wire harness 200 is connected to the floor harness and a connector.
