Movement toward the first opening 22B along the longitudinal direction D2 is restricted. That is, it is possible to prevent the engaging portion 13 from coming off from the first hole portion 22C. Similarly, the second hole portion 23C restricts the tip portion 132 of the engaging portion 13 from moving along the longitudinal direction D3 of the second cylindrical portion 23 toward the second opening 23B. That is, it is possible to prevent the engaging portion 13 from coming off from the second hole portion 23C. As a result, the ear hook arm 10 can be detachably engaged with the mask body 20 with a simple structure.

Next, a modified example of the engaging portion 13 of the ear hanging arm 10 will be described with reference to FIGS. 1 and 4. FIG. The proximal end portion 131 of the engaging portion 13 preferably has a first proximal end portion 131A and a second proximal end portion 131B. The first base end portion 131A is connected to the other end 11B of the arm portion 11 . The second base end portion 131B has, for example, a horizontally long rectangular plate shape. The second proximal end portion 131B communicates between the first proximal end portion 131A and the distal end portion 132 of the engaging portion 13 . The first base end portion 131A protrudes from the second base end portion 131B in the longitudinal direction D1 of the arm portion 11 . The width of the first base end portion 131A along the direction perpendicular to the longitudinal direction D1 is greater than the widths of the first hole portion 22C of the first tubular portion 22 and the width of the second hole portion 23C of the second tubular portion 23 . The width of the first base end portion 131A is, for example, 8 mm.

According to this preferred example, when viewed from the longitudinal direction D1 of the arm portion 11, the first base end portion 131A protrudes more than the second base end portion 131B, so that the first hole portion 22C is positioned in the first hole portion 22C. The base end portion 131A is restricted from moving along the longitudinal direction D2 of the first tubular portion 22 toward the back side when viewed from the first opening 22B side. That is, it is possible to prevent the second base end portion 131B from coming out of the first hole portion 22C. Similarly, the second hole portion 23C restricts the first base end portion 131A from moving along the longitudinal direction D3 of the second cylindrical portion 23 toward the back side when viewed from the second opening 23B side. That is, it is possible to prevent the second base end portion 131B from coming out of the second hole portion 23C. Therefore, positional deviation of the engagement position of the ear hook arm 10 can be reduced with a simple configuration. As a result, the wearing comfort of the mask 1 can be further improved.
