(Description of protective body)
The protective body 5 attached to the base body 4 described above is formed in substantially the same shape as the front half portion 11 of the base body 4, and as shown in FIG. It has first to fourth extension portions 32 to 35 protruding from the body portion 31 . The body portion 31 is formed in a shape that covers the chest and abdomen of the user 2 . The first extension portion 32 and the second extension portion 33 extend to a portion covering the shoulders of the user 2 . The third extension part 34 and the fourth extension part 35 extend to the part covering the user's 2 flanks. That is, the protector 5 according to this embodiment includes first and second extensions 32 and 33 extending from the main body 31 to cover the shoulders of the user 2, and covering the flanks of the user 2 from the main body 31. It has third and fourth extensions 34, 35 extending to the site.

As shown in FIG. 4, the protector 5 is composed of a plurality of laminated sheets 41 and a holder 42 that covers and holds the sheets 41. As shown in FIG. The plurality of sheets 41 are formed in a foil shape from a metal material and laminated so that the thickness direction thereof coincides with the thickness direction of the outer material 21 and the lining material 22 of the substrate 4 . Further, the sheet 41 is formed so as to extend continuously over the entire area of the body portion 31 of the protective body 5 and the first to fourth extension portions 32 to 35 . The metallic material forming the sheet 41 according to this embodiment is a titanium sheet or foil. The metal material forming the sheet 41 includes a thin plate or foil made of any one of stainless steel, aluminum, iron, and magnesium. There are the following three patterns for forming the plurality of sheets 41 of the protector 5 .

(1) All the sheets 41 of the protector 5 are sheets 41 made of titanium.
(2) All the sheets 41 of the protector 5 are sheets 41 made of any one metal material of stainless steel, aluminum, iron, and magnesium.
(3) One or more sheets 41 made of any one metal material of aluminum, iron, and magnesium are mixed with one or more sheets 41 made of titanium.

The thickness of each sheet 41 is desirably 0.6 mm or less. The reason why the thickness is set to 0.6 mm or less is that if the sheet 41 is thicker than 0.6 mm, it becomes difficult to bend and the weight increases. Also, since each sheet 41 is thin, it can be cut into a desired shape with scissors, for example. The number of sheets 41 is desirably about 15 when the thickness of one sheet 41 is 0.6 mm. 4, the number of sheets 41 is reduced in order to facilitate understanding of the structure. The reason why the number of sheets 41 is about 15 is that if the number exceeds 15, the protector 5 becomes difficult to bend and becomes heavy and difficult to handle.

The holding body 42 is formed in a bag-like shape by, for example, a woven fabric, a net, or a non-woven fabric made of synthetic fibers. It is held so as to be slidable. The protective body 5 is mounted on the base body 4 by inserting the protective body 5 formed by accommodating a plurality of sheets 41 in the holding body 42 thus formed into the bag portion 23 of the front half portion 11 of the base body 4 . It will be.
When the protective body 5 is attached to the base body 4 and a force is applied to bend the protective body 5, the adjacent sheets 41 slide freely against each other and each sheet 41 bends due to elastic deformation to protect the body. The body 5 becomes flexed.

Therefore, the protective body 5 of the protective clothing 1 can be easily bent, so that it has high flexibility. In addition, since the protector 5 can be formed without arranging the sheets 41 in the vertical or horizontal direction, there is no gap and the manufacturing is simple. Furthermore, the sheet 41 made of a foil-like metal material is easy to cut, and thus has a high degree of freedom in shape.
Therefore, according to this embodiment, it is possible to provide a protective body which is formed so as to have high flexibility without forming a gap, and which can be easily manufactured into a free shape.
In addition, according to the protective clothing 1 having the protective body 5 according to this embodiment, since a plurality of sheets 41 are laminated in the thickness direction of the cloth-like body, the performance of the protective body 5 can be fully exhibited. It can be worn by the user.
