The spring 50 is inserted from the inside of the coupling groove 39 and pushes the coupling bolt 40 outward by the elastic force of the spring 50 to prevent the coupling bolt 40 from being released . Therefore, the building exterior material provided by the coupling bolts 40 can be firmly and securely fixed even if the time passes. Further, by inserting the spring 50 into the engaging groove 39, it is not necessary to provide a structure such as a spring washer so as to protrude outward, and the building exterior member can be more firmly engaged. That is, in the case of installing the saddle ring washer, it is difficult to secure a strong fastening force because the contact surface where slippage may occur due to both surfaces of the spring washer is increased, and this embodiment can solve this problem.

Referring to FIG. 5, the present embodiment may include a lid 60 covering the rotation support 37. The lid 60 may be formed of stainless steel, aluminum, plastic, or the like. By covering the rotation supporting portion 37 with the lid 60, corrosion of the rotation supporting portion 37 can be prevented and heat transfer through the rotation supporting portion 37 can be prevented. In other words, by preventing corrosion and heat transfer, it is possible to prevent damage to the rotary support 37 and to use it for a long time, and to improve the heat insulation effect.

In this embodiment, the outer body 35 and the rotary support 37 can be coated (not shown). By coating the outer body 35 and the rotary support 37, the outer body 35 and the rotary support 37 can be prevented from being thermally insulated or corroded.
