[Second embodiment]

 A second embodiment is shown in FIGS.

In these drawings, FIG. 4 is a front view, FIG. 5 is an enlarged front view of a main part, FIG. 6 is a partially cutaway side view of the main part, and FIG. 7 is a plan view of a mounting rod.

The cable receiving object B2 in the second embodiment is horizontally placed on the side wall pieces 90b, 90b of the main frame 90 having the groove-shaped cross section, which is composed of the bottom wall piece 90a and the side wall piece 90b. 91 are continuously provided, and the bottom wall piece 90a is inclined so that the base side is gradually lowered, and the height width is gradually widened from the free end side tip toward the base side. The cable C is placed on the section piece 91 to support the cable C, and the cable C is stretched between the cable receivers to install the cable on the wall surface of the cave.

The attachment rod D2 for attaching the cable hanger A to the cable receiver B2 is formed by bending one metal rod as in the first embodiment. That is, the pair of horizontal portions 18a, 18b and the vertical portions 19a, 19b, 20a, 20b that are provided to be opposed to each other via the horizontal portions 18a, 18b constitute a pair of hook portions 4, 4, and the hook portions 4 One of the vertical portions 19b and 20b of 4, 4 is connected directly to the horizontal portions 18a and 18b of the hooking portion 4 so as to be positioned directly below the horizontal portions 18a and 18b. A horizontal rod portion of the latching portion 4 which is continuous with the other vertical portion 19a corresponding to the one vertical portion 19b continuous with the press contact portion 21 is referred to as a first receiving / supporting portion 8, and the first receiving / supporting portion 8 is provided. One of the rods of the press-contact portion 21 located on the extension line of is the second receiving support portion 9 and is sufficient to allow the fastening bolt 25 to penetrate at least between the horizontal portions 18a and 18b of the retaining portion 4. A gap 26 is provided.

The other one of the horizontal rods 23, which is adjacent to the second receiving and supporting portion 9 and constitutes the pressure contact portion 21, is arranged at a position slightly lower than the second receiving and supporting portion 9.

This corresponds to the inclination of the bottom wall piece 90a of the main frame 90 of the cable receiver B2, and the operation of the tightening bolt 25 described later causes the entire pressure contact portion 21 to move to the bottom wall piece 90a of the cable receiver B2. This is for surely press-contacting and strengthening the mounting state.
