Protectors for protecting players who play the above-mentioned sports are often made of leather and are stuffed with cushioning material if necessary. All of them were heavy, had poor air permeability, did not withstand much abrasion, and would break if sharp edges such as metal came into contact with them, so there was still room for improvement.

The protector 1 of the present invention, an example of which is shown in the drawings, includes:
Cloth or mesh 3A, 3 made of ultra-high molecular weight polyethylene fibers is attached to one or both surfaces (both surfaces in the figure) of the shock absorber 2 made of an elastic material such as rubber.
It is characterized by being made by overlapping B. The ultra-high molecular weight polyethylene used in this invention has an intrinsic viscosity [η] of 5 at 135°C in decalin solvent.
dl/g or more, preferably in the range of 7 to 30 dl/g. When [η] is less than 5 dl/g, it is easy to form fibers, but even when stretched, fibers with excellent tensile strength cannot be obtained. On the other hand, the upper limit of [η] is not particularly limited, but if it exceeds 30 dl/g, it tends to be difficult to form fibers. The above-mentioned ultra-high molecular weight polyethylene is obtained by polymerizing ethylene or ethylene with a small amount of other α-olefins such as propylene, 1-butene, 4-methyl-1-pentene, 1-hexene, etc. by a so-called medium-low pressure polymerization method. Among the polyethylenes obtained by polyethylene, it has a much higher molecular weight. In addition, the ultra-high molecular weight polyethylene fibers in the present invention are fibers, tapes, or fibers obtained by fibrillating tapes, which have highly oriented ultra-high molecular weight polyethylene molecular chains and have high elastic modulus and high tensile strength. . The method for manufacturing fibers having such characteristics is not limited to the above, but for example,
15408, a method of diluting ultra-high molecular weight polyethylene with a solvent and then spinning and drawing, as described in JP-A-58-5228, or JP-A-59-1999.
It can be adjusted by the method disclosed in Japanese Patent Publication No. 108116 and Japanese Patent Application Laid-Open No. 187614/1983. The ultra-high molecular weight polyethylene fiber used in the present invention has a tensile modulus (initial) of 30 GPa or more, preferably 500 GPa or more,
It is preferable that the tensile strength is 1.5 GPa or more, preferably 1.7 GPa or more, and the elongation is 6% or less, preferably 4% or less. The material and shape of the shock absorber 2 are arbitrary.
Further, it may be formed by combining other materials as necessary.

As shown in Figure 2, this protector deforms slightly when it receives an impact, but because it does not stretch much, the impact does not reach the inside, providing good protection for the player wearing it. Objects that collide from an oblique direction slide along the surface, softening the impact. Effects of the invention The protector of this invention can be made light in weight, has good breathability, slipperiness, abrasion resistance, etc.
Since it also has excellent shock absorbing ability, it is suitable as a protector for sports such as ice hockey, American football, and baseball. It also has the advantage of being highly abrasion resistant and difficult to cut even when exposed to sharp edges.
