On the other hand, the bent portion 120 is preferably the upper portion (120a) and the lower portion (120b) is made of a plurality of variable members to bend. That is, although not explicitly shown in Figure 3, the upper portion (120a) and the lower portion (120b) of the bent portion 120 is formed because a plurality of variable members are overlapping may have a shape as if wrinkles when viewed from the outside. In addition, the upper portion 120a and the lower portion 120b may be each formed of a plurality of variable members so that the curved portion 120 may be bent.

Hereinafter, with reference to the drawings, the structure and operation of the bent portion 120 will be described.

4 is a cross-sectional view showing a part of the upper portion 120a of the bend 120. Referring to FIG. 4, the curved portion 120 may be formed of a plurality of variable members 121 formed so that portions thereof overlap each other.

That is, the frame 110 or the bent part 120 may be formed by the shape of the body 110 contacting the outer surface of the frame 110 while the frame 110 is drawn into the body. It may include a plurality of variable members 121 provided to overlap each other so that the shape can be changed or bent.

As shown in FIG. 4, the variable members 121 have the same shape and structure, and either end of the variable member 121 in the longitudinal direction of the frame 110 or in the transport direction of the treatment unit 130 may be formed. The neighboring variable member 121 may be inserted into the inner side, and the other end of the variable member 121 may have an outer side of the neighboring variable member 121 inserted therein. Since the adjacent variable members 121 have a form in which parts of the neighboring variable members 121 are overlapped with each other, the bent part 120 may be bent or deformed while being connected or contacted with each other.
