It will surely be maintained. That is, in a configuration in which a rotating member is provided on the insertion port side of the flat wire to maintain the connection state on the insertion port side, a force for releasing the connection state by drawing the flat wire in the connection state or the like is directly. In contrast to the fact that the connection state is easily released by acting on the rotating member, in the present invention in which the rotating member 4 is provided in the opening 6 opposite to the insertion port 5, the flat electric wire 8 is provided. Since the force due to the drawing and the like does not directly act on the rotating member 4,
The connection state is more reliably maintained.
