As described above, according to the present invention, the core wire of the service wire inserted from the insertion hole is elastically sandwiched by the sandwiching member having the internal conductivity, and the mixed output of the antennas for BS and UHF / VHF is provided. The terminal portion to be connected, and the holding metal fitting pivotally supported by the shaft supporting portions provided on both sides of the terminal portion to hold the covering portion of the lead-in wire between the lead-in device body and the holding wire holding portion of the holding metal fitting. Since a fixed piece that is screwed to the main body of the retractor from one side is formed, the retractor can be connected to the terminal part by a so-called quick connection method, and the mixed output of the antennas for BS and UHF / VHF of the retractor It is easy to connect with, and the pressing metal fitting is rotated to hold the cover part of the lead wire between the lead-in device body and fix it by screwing only one side to the fixing piece. As when using the metal fittings , It is not necessary to position the retainer member, and since it is possible to fix the bracket holding a single screw, anchorage work is also easy, thus it is possible to save construction of connection of the retraction line.
