The front surface12AF, the upper side surface12AA, and the side surfaces12AB are covered with the housing body11(an example of a cover member). Accordingly, in the attachment member10according to the embodiment, ion dust (dust, sand, leaves, or the like) can be more effectively prevented from accumulating on the upper side surface12AA and the side surface12AB in which the through holes14A to16A are formed, the upper surface12AC, and the intermediate upper surface12AD.

In addition, the housing body11of the attachment member10according to the embodiment covers the through holes14A to16A. Accordingly, in the attachment member10according to the embodiment, dust (dust, sand, leaves, or the like) can be more effectively prevented from accumulating in the through holes14A to16A.

The gaps18(an example of a gap) through which the belts B1to B3can be respectively inserted are formed between the housing body11and the pair of upper side surfaces12AA and the pair of side surfaces12AB of the attachment member10according to the embodiment. Accordingly, in the attachment member10according to the embodiment, each of the belts B1to B3inserted through a respective one of the through holes14A to16A can be drawn out of the housing body11, and attachment to the pole PL by each of the belts B1to B3can be implemented.

The housing body11of the attachment member10according to the embodiment covers the back plate12D. The gap18through which the belts B1to B3can pass is formed between the side surface of the back plate12D and the housing body11. Accordingly, the housing body11of the attachment member10according to the embodiment can be attached to the pole PL.

The pair of side surfaces of the attachment member10according to the embodiment include the upper side surfaces12AA and the side surfaces12AB (an example of the intermediate side surface), and the intermediate upper surface12AD connecting the lower end of the upper side surface12AA and the upper end of the side surface12AB is provided. The through hole15A (an example of an intermediate through hole) having an opened upper end is provided at the upper end of the side surface12AB. The notch portion15B (an example of a notch) continuous with the upper end of the through hole15A is formed in the intermediate upper surface12AD. Accordingly, in the attachment member10according to the embodiment, water droplets such as rainwater are less likely to accumulate on the intermediate upper surface12AD, and a salt adhering to the belt B2inserted through the through hole15A is easily washed away with the water droplets. Therefore, in the attachment member10, deterioration of the base member12due to water droplets and the salt can be more effectively prevented.

Various embodiments have been described above with reference to the drawings, but the present disclosure is not limited thereto. It is apparent to a person skilled in the art that various changes, modifications, substitutions, additions, deletions, and equivalents can be conceived within the scope of the claims, and it is understood that such modifications also belong to the technical scope of the present disclosure.
