The air holes 21 can be formed in each of the portions 20, and the air permeability can be further improved.

Next, another embodiment is shown in FIG. Another embodiment has a pair of left and right ridges 30, 30 arranged in parallel along the front tip portion k of the shin portion Kc on the inner surface 2 a side.
In the mounted state, a concave strip portion 31 into which the front tip portion k of the shin portion Kc enters is formed between the pair of left and right convex strip portions 30, 30 so as to prevent positional displacement and reduce the impact. It is.
4, 5, and 7, in order to facilitate the distinction between the lower leg portion K when worn indicated by a two-dot chain line and the lower leg covering member 2 indicated by a solid line, It is shown with some gaps.

The design of the present invention can be changed, and the lower leg covering member 2 may be divided into four parts in the vertical direction to form four divided covering parts . Moreover, in the connection part 20, you may provide the non-sewing site | part 29 1 location, 2 locations, or 4 or more locations. That is, one, two, or four or more vent holes 21 may be formed in the connecting portion 20. Further, the lower leg covering member 2 forms the ridge 30 by heat compression molding (or cold press molding) of the outer covering member 51 with an upper die having a concave groove and a flat lower die, and a cushion member 53 is formed. May be omitted. Further, the inner covering member 52 is heat compression molded (or cold press molded) with a female die having a concave groove and a male die having a convex portion to form a concave groove recessed in the inner surface 2a direction. Alternatively, the cushion member 53 may be fitted and sewn. The belt of each female buckle member 41, 43, 45 may be a rubber belt. The lower leg upper female buckle member 43 and the lower leg upper male buckle member 44 may be engaged with each other.

  As described above, the leg protector of the present invention includes the crus protection unit 1 that protects the crus K from the vicinity of the knee Ka to the ankle Kb of the human body, and the crus protection unit 1 corresponds to the shin Kc of the human body. Cross section C having a shin protection member 3 for protecting the front and flexible left and right projecting pieces 25 and 25 for protecting the left and right side surfaces of the lower leg K and attached to the back surface 3a side of the shin protection member 3 Since the lower leg covering member 2 is divided in the vertical direction to form two or more divided covering parts 2A and 2B, three-dimensionally, the parts having different thicknesses are three-dimensionally formed. Correspondingly along the line, the lower leg K can be protected. The divided covering portions 2A and 2B can be formed into shapes corresponding to the portions to be protected, respectively, and adhesion can be improved to prevent positional displacement and can be reliably protected. The belt tightening force of the buckle member can be adjusted independently according to different parts of the lower leg K, and the uncomfortable feeling at the time of wearing can be reduced. Generation of an unnecessary space (gap) between the lower leg covering member 2 and the lower leg part K can be prevented, and adhesion can be improved. Even if either the upper part or the lower part of the lower leg K is strongly tightened with a rubber belt or the like of the buckle member, there is no deformation that causes the other to be pulled in, and a desired adhesion force (clamping force) according to different thickness parts ) Can be obtained.

  Further, it has a connecting portion 20 for connecting the divided covering portions 2A and 2B adjacent in the vertical direction to each other by sewing, and the connecting portion 20 has a vent hole 21 for communicating the inner surface 2a side and the outer surface 2b with a non-sewing part. Since it is formed by 29, the stuffiness between the user and the lower leg covering member 2 can be reduced, and the user can play comfortably. Hot air can be discharged from between the user and the lower leg covering member 2. Or outside air can be taken in.
