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

The front guide seating portion 71b is a device portion forming a front portion and a lower portion of the mask seating surface on which the mask portion 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 seating portion 71b is located in the front upper portion of the front guide seating portion 71b.

The load distribution and seating portion 76b is a device that forms the rear portion and the upper portion of the mask seating surface, and is continuously formed on the upper portion of the front guide seating portion 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 concave shape below the extension line connecting the upper end and the lower end of the neck cover 13 in a straight line. The load distribution seating portion 76b is formed in a shape that is convex upward on the upper side of the extension line connecting the upper end and the lower end of the neck cover 13 in a straight line.

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

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

The sliding bent portion 131 constituting the lower portion of the neck cover portion 13 is provided with a front guide seating portion 71b having a curved shape in which the slope of the tangent line increases toward the rear, so that the inclination toward the rear is more stable. In a constrained state, it may be seated in a correct position on the front guide seating portion 71b.

In addition, as the load distribution seating portion 76b has a curved shape to protrude toward the center of curvature of the front guide seating portion 71b, the overhanging bent portion 132 constituting the upper portion of the neck cover portion 13 is load-distributing. It is caught on the seating portion 76b. Accordingly, the load of the mask portion 10 is not concentrated only on the front guide seating portion 71b supporting the lower end of the mask portion 10, but the load distribution seating portion 76b over which the spanning bent portion 132 is applied. Even the load of the mask part 10 is distributed and acts.

Accordingly, in mounting the mask portion 10 on the mask holder 70 in an inclined shape so that the lower portion thereof is positioned in front, the load of the mask portion 10 is applied to the front guide seating portion 71b and the load distribution seating portion. It can act more evenly distributed over the entire mask seating surface including (76b). By this action, structural stability of the mask holder 70 supporting the mask portion 10 can be secured.

The front guide seating portion 71b according to an embodiment of the present invention is formed on the mask seating portion 72 of the mask mounting portion 71, and the load-distributing seating portion 76b seats the mask holding portion 76. It is formed on the interlocking rotation part 764. However, the front guide seating portion 71b and the load-distributing seating portion 76b according to the present invention are classified according to their curved shape and position, and the mask holding portion 76 is formed to extend more forward or the mask When disposed in the middle of the seating portion 72 in the extending direction, the front end portion of the mask holding portion 76 may form a part of the front guide seating portion 71b. In addition, the mask seating portion 72 may form a part of the load distribution seating portion 76b.
