In consideration of the fact that the two attachment members 15a and 15a are fixed to the construction material, the urging member 23 may not be disposed, and may be arbitrarily selected.
Furthermore, the configuration of the right end 6 and the attachment member 15a in FIG. 7 may be configured symmetrically with the configuration on the left side shown in FIGS. However, since the case 2 and the mounting member 15a only need to be relatively rotatable, a configuration in which the fitting portion 28 and the locking portion 17 are not provided may be employed.

A method of installing the distributor 1 having the above-described configuration with respect to the construction material and a use state will be described.
First, based on the position of the TV terminal, the position of the device to be connected (for example, TV, VCR, DVD recorder) and the direction of its input terminal, the installation worker can attach the distributor 1 to the construction material, A wiring plan of the coaxial cable 51 connected to the connector seat 10 is assumed.

Next, the protruding direction of the plug seat 10 is adjusted so as to correspond to the assumed wiring plan. The adjustment method may be as follows.
