The arm assembly portion 791 is formed to protrude laterally on the holder outer skin 78 . A groove recessed from one end facing the holder inner skin 77 to the other end is formed on the arm assembly portion 791 . The through-hole portion 792 is formed to pass through in the transverse direction at a position corresponding to the arm assembly portion 791 of the holder inner skin 77 . The holder fastening member 793 has a male screw structure, passes through the through hole 792 and is screwed to the female assembly 791 . By the assembly structure between the arm assembly part 791, the through hole part 792, and the holder fastening member 793 as described above, the holder inner skin 77 and the holder outer skin 78 can be firmly coupled to each other.

A groove in which the head of the holder fastening member 793 can be accommodated is formed on the through hole 792 . In the state in which the holder fastening member 793 is fastened, the head portion of the holder fastening member 793 is accommodated in the through hole 792 and does not protrude from the holder inner skin 77 . The attachment cover 794 covers the head portion of the holder fastening member 793 exposed to the outside of the holder inner skin 77 and is attached to the holder inner skin 77 . As the attachment cover 794, a sticker member having an adhesive applied thereto may be applied. In applying the sticker member as the attachment cover 794, by applying various colors and textures that are in harmony with the color and texture of the inner skin 77 of the holder, it is possible to further improve the aesthetics.

The mask seating part 72 and the seating interlocking rotation part 764 of the mask holder 70 together form a continuous mask seating surface corresponding to the lower edge of the mask part 10 . Referring to FIGS. 4 and 26 , the mask seating surface on which the mask part 10 of the mask holder 70 is seated includes a front guide seating part 71b and a load distribution seating part 76b.

The front guide seating part 71b is a device part forming a front part and a lower part of the mask seating surface on which the mask part 10 is seated, and forms a curved surface in which the slope of the tangent line increases toward the rear. The center of curvature of the front guide seat part 71b is located on the front upper part of the front guide seat part 71b.

The load distribution seating part 76b is a device part forming the rear part and the upper part of the mask seating surface, and is formed continuously on the upper part of the front guidance seating part 71b, and forms a curved surface in which the slope of the tangent line decreases toward the rear. The center of curvature of the load distribution and seating portion 76b is located at the rear lower portion of the load distribution and seating portion 76b.

The front guide seating portion 71b is formed in a shape concave downwardly below the extension line connecting the upper end and the lower end of the neck cover portion 13 in a straight line. The load distribution seating part 76b is formed in a convex shape upwardly above the extension line connecting the upper end and the lower end of the neck cover part 13 in a straight line.

The edge of the neck cover part 13 constituting the lower part of the mask part 10 has a curved shape corresponding to the front guide seat part 71b and the load distribution seat part 76b. The edge portion of the neck cover portion 13 according to an embodiment of the present invention includes a sliding curved portion 131 and a spanning curved portion 132 . The edge of the neck cover part 13 is formed by assembling the lower gap cover part 121d and the assembled cover part 127 to form a continuous curved surface.

The sliding bent portion 131 has a shape corresponding to the front guide seat portion 71b, that is, a curved shape in which the slope of the tangent line increases toward the rear. The spanning bending portion 132 has a shape corresponding to the load distribution and seating portion 76b, that is, a curved shape in which the slope of the tangent line decreases toward the rear. The sliding bent portion 131 is seated on the front guide seat portion 71b, and the spanning bend portion 132 is seated on the load distribution seat portion 76b.

The sliding bent part 131 constituting the lower part of the neck cover part 13 is provided with a front guide seating part 71b having a curved surface shape in which the inclination of the tangent line increases toward the rear, so that the inclination to the rear is more stable. It may be seated in a fixed position on the front guidance seating portion 71b in a restrained state.

In addition, as the load distribution seating part 76b has a curved shape to protrude toward the center of curvature of the front guidance seating part 71b, the spanning bending part 132 constituting the upper part of the neck cover part 13 is a load distribution It is caught in the seating portion (76b). Accordingly, the load of the mask part 10 is not concentrated only on the front guide seat part 71b that supports the lower end of the mask part 10, but the load distribution seat part 76b on which the spanning bending part 132 is spread. Also, the load of the mask unit 10 is distributed and acts.

Accordingly, when the mask part 10 is mounted on the mask holder 70 in an inclined shape so that the lower part thereof is positioned in the front, the load of the mask part 10 is applied to the front guide seat part 71b and the load distribution seat part. It can act more uniformly over the entire mask seating surface including (76b). Structural stability of the mask holder 70 supporting the mask unit 10 can be secured by this action.

The front guidance seating part 71b according to an embodiment of the present invention is formed on the mask seating part 72 of the mask holder 71, and the load distribution seating part 76b is the seating of the mask holding part 76. It is formed on the interlocking rotation unit 764 . However, the front guidance seating part 71b and the load distribution seating part 76b according to the present invention have names that are distinguished according to the curved shape and position, and the mask holding part 76 is formed to extend more forward, or the mask When disposed in the middle portion of the extension direction of the seating portion 72, the front end of the mask holding portion 76 may form a part of the front guide seating portion (71b). In addition, the mask seating part 72 may form a part of the load distribution seating part 76b.

Although the present invention has been described with reference to the embodiment shown in the drawings, this is merely exemplary, and it is understood that various modifications and equivalent other embodiments are possible by those of ordinary skill in the art. will understand Accordingly, the true technical protection scope of the present invention should be defined by the following claims.
