The thin-film antibacterial member joint includes a main body 51 and a fixing part 52 . The body 51 is attached to the grip portion 20 and is made of a soft material having a longitudinal groove in the center thereof. Looking at the side cross-section of the joint of the thin film antibacterial member as shown in FIG. 5 , the main body 51 has a semi-circular column shape formed in the longitudinal direction, one surface is flat, and the other surface has a curved surface, and the length is at the center of the curved surface. It has a groove of a predetermined size in the direction. The curvature of the curved surface does not need to be determined and may vary depending on the grip unit 20 . For example, when the grip portion 20 is large, the curvature may be increased, and if the grip portion 20 is small, the curvature may also be decreased. And since the body 51 is a soft material including rubber, fabric, leather, paper, and plastic material, when attached to the grip part 20 having a curved surface, it can be bent by elasticity, so that it can be closely attached to the grip part 20 have.

The fixing part 52 is seated in the groove to bite into and fix a part of the thin film antibacterial member covering the surface of the body 51 . Referring to FIG. 5 , the shape of the fixing part 52 has been described using a cylinder as an example, but various shapes such as a square pillar and a polygonal pillar are possible. In addition, the thickness of the cylinder does not need to be determined, and may vary according to the size of the body 51 .

The body 51 may be formed to be elongated in the longitudinal direction, but the length may vary depending on the grip portion 20 to be attached. In addition, the size of the groove may be formed in various ways. In addition, the degree of exposure of the groove may vary according to the characteristics of the material of the body 51 . The fixing part 52 is covered with any one of copper, gold foil, gold plating, silver foil, and silver plating material, and the purity is 95% or more. The higher the purity, the better, and it may be 50% or more that antibacterial and antiviral properties are maintained, but is preferably 95% or more. However, when the exposure of the groove to the outside is small, that is, when the fixing part 52 is completely seated in the groove, the exposure of the fixing part 52 is small or even there is no exposure, so the fixing part 52 is not exposed. Antibacterial, antiviral material may not be necessary.

If the process of installing to the grip part 20 is described in more detail, a thin film antibacterial member 40 is prepared so as to have antibacterial and antiviral functions on the surface of the cylindrical grip part 20 and covered on the surface of the main body 51 or attach The thin film antibacterial member 40 is covered with any one of copper, gold foil, gold plating, silver foil, and silver plating material, and the purity is 95% or more. That is, the higher the purity, the better, it may be 50% or more that antibacterial and antiviral properties are maintained, but is preferably 95% or more. Since the thin film antibacterial member 40 is a thin flat material, it has an end, and the end portion is positioned so that it can be folded into the groove portion of the body 51 . On the other hand, since the thin film antibacterial member 40 is a thin metal material, the tip is very sharp.

When the end of the thin-film antibacterial member 40 is positioned so that it can be folded into the groove portion of the body 51, the fixing part 52 is inserted into the groove to bite the thin-film antibacterial member 40 and fix it in the groove. On the other hand, when the fixing part 52 is seated in the groove of the main body 51 , the fixing part 52 may be completely buried in the groove without being exposed to the outside due to the elasticity of the soft material of the body 51 .
