Even if the air flowing through the holes 63' is sent toward the user's U eyeglasses 100B, the air flowing toward the eyes of the user U can be sent out, and the desired effect can be achieved.

That is, the wearable item 100 includes a mask 100A that covers the mouth and nose of the user U, and glasses 100B that covers the eyes of the user U, and directs the circulating air toward the user U's glasses 100B (facing the user U's eyes). The desired effect can also be achieved by having a sending section 63 that sends out toward the side). However, in the eyeglass side tubes 60, 260, the delivery portions 63, 262 are positioned below the eyeglasses 100B, or the eyeglass side tubes 60, 260 are configured to reach the lower side of the inner side 100B' of the eyeglasses 100B. This is a more preferable embodiment since it is possible to reliably send out the air that circulates to the eyes of the user U.

Furthermore, in the embodiment described above, the wearable item 100 is a mask 100A or glasses 100B, but it may also be used as a protective device such as an eye shield to protect the eyes or a protective device to protect the mouth such as a mouth shield. The desired effect can be achieved.
In addition, in the first and second embodiments described above, the magnet 80 on the inside 110A of the mask 100A and the mask side tubes 40, 240 are fixed in advance using an adhesive (adhesive) as the fixing part 90 to set the attached item. 1 and 2 may be assembled. Furthermore, in the third embodiment described above, the attachment set 4 may be assembled by fixing the cup body 312 and the magnet 313 on the inside 110A of the mask 100A in advance using an adhesive (adhesive) as a fixing part. Furthermore, in the fifth embodiment described above, the first filling portion 531 may include an adhesive (adhesive). Furthermore, in the fifth embodiment described above, the first filling part 531 is interposed between the magnet 522 on the inner side 100C1 of the face shield 100C and the inner side 100C1 of the face shield 100, but as shown in FIG. In addition, the desired effect can also be achieved by interposing between the surface 532a of the second filling portion 532 facing the inner side 100C1 of the face shield 100C and the magnet 522 on the inner side 100C1 of the face shield 100C.
