The conventional protectors described above have common problems. That is, since the electric wire is pressed from the upper part of the electric wire by the pressing member or the lid or pressed by the partition plate, a large force is required to press the electric wire when the amount of the electric wire increases. For this reason, when there are many electric wires, the work for attaching the pressing member and the lid becomes difficult, and the workability is poor. Also,
Since the electric wire continues to be strongly pushed in the protector, when the electric wires are arranged in a cross shape, the coating may be damaged and an undesired accident such as a short circuit may occur. An object of the present invention is to provide a protector capable of maximally utilizing the effective cross-sectional area in the protector and improving workability when performing the wire installation work of the protector, and a method of installing the wire in the protector. is there.
