In addition, the adhesive member is located at the position on the inner surface of the hood portion 12 corresponding to the position where the adhesive member 15 is folded back when the headband 14 is folded back to the upper side of the hood portion 12 at the sewing position 17 of the headband 14. The other adhesive member 16 for receiving 15 is provided.
Inside the hood part 12, a protect part 21 that covers the head of the user 30 is arranged.
The protect part 21 has a hemispherical protection member 22 shown in FIG. 4 and a headband part 23 surrounding the head periphery shown in FIG. FIG. 6 shows the mounting state of the protection member 22 and the headband portion 23.

  As shown in FIG. 4, the protection member 22 is formed of a hemispherical main body formed of a hard resin such as polyethylene, a plurality of slit holes 41 are provided at the top, and a plurality of slits 42 are provided on the side wall. Is provided. The slit 42 has a function of adjusting the hemispherical size of the protective member 22 corresponding to the size of the head of the user 30 when the user 30 wears the protective member 22. A plurality of oblong holes 43, 431, 44, 441 are formed in the side wall of the protection member 22. The oval holes 43 and 431 are located in the back of the head when the protective member 22 is put on the head, and the oval holes 44 and 441 are located in the forehead. The oval hole 43 is provided at a position below the oval hole 431, and the oval hole 44 is provided at a position above the oval hole 441. The oval holes 43, 431, 44, and 441 function as attachment holes for the headband portion 23 shown in FIG.

As shown in FIG. 5, the headband portion 23 has a band 45 formed of a flexible resin, and a plurality of through holes 46 arranged in the length direction of the band 45 are formed at one end of the band 45. At the other end, a slider 47 having a protruding member that can be fitted into any of the through holes 46 is provided. The slider 47 and the through hole 46 constitute a length adjusting member of the band 45, and the slider 47 is slid in the length direction of the band 45 and fitted into one of the through holes 46, so that the head 30 of the user 30 is fitted. The length of the band 45 is adjusted according to the size, and the size of the diameter formed by the band 45 can be adjusted.
A plurality of branches 48 extending in a direction intersecting the length direction of the band 45 are provided at a plurality of locations of the band 45, and protrusions 49 are formed in the vicinity of the tips of the branches 48. The projection 49 can be fitted into the small holes 43, 431, 44, 441 on the side wall of the protective member 22, and is not easily detached when fitted into the small holes 43, 431, 44, 441. 5 (b), a rod-like portion 491 having a width substantially equal to the hole width of the oval holes 43, 431, 44, 441 and penetrating through the oval holes 43, 431, 44, 441, and the oval holes 43, The stopper 492 has a diameter larger than the hole width of 431, 44, 441.

  As shown in FIG. 6, when the plurality of protrusions 49 of the headband portion 23 are respectively fitted into the plurality of small holes 43 and 44 of the protection member 22, the protection member 22 and the headband portion 23 are connected to the protrusions 49 and the small holes 43. , 44 are connected by fitting members. At this time, since the position of the oval hole 43 is below the oval hole 44, an opening 50 is formed between the protection member 22 and the headband portion 23 at the back of the head when the protection member 22 is put on the head. The On the other hand, on the frontal side, the lower end of the protection member 22 and the headband part 23 overlap, and no opening is formed. When it is desired to form an opening also on the front head side, the oval hole 44 into which the protrusion 49 is fitted may be changed to the lower oval hole 441. Further, when the head is small, the oval hole 43 into which the protrusion 49 is fitted may be the upper oval hole 431.

Next, a method for mounting the protect portion 21 inside the hood portion 12 will be described.
First, as shown in FIGS. 2 and 3, the headband 14 of the hood portion 12 is opened downward, and the protect portion 21 in which the headband portion 23 is attached to the protection member 22 as shown in FIG. 6 inside the hood portion 12. Is inserted. At this time, it inserts so that the length adjustment member which consists of the slider 47 and the through-hole 46 may be arrange | positioned in the position corresponding to the back head of the hood part 12. FIG.
