Mounting to the part A can be facilitated. Moreover, it can be attached in close contact with the lower leg part A, and the leg part can be further protected by preventing the protective device from shifting. Further, since the belt member 40 can be worn while reducing the surface directly pressing the lower leg A, it is possible to reduce discomfort and discomfort during wearing.

  Further, in the leg protector provided with the crus protection part 22, at least the outer skin member 12 and the endothelial member 13 are laminated as constituent members, and crossing the crus protection part 22 in the unmounted state by sewing in the vertical direction. Since the surface shape is formed in a C-shaped entrainment shape, it can be easily attached to the lower leg A. Further, since the outer skin member 12 and the inner skin member 13 are laminated and sewn, it is possible to suppress the compression caused by the fastening of the belt member 40 or the like to the lower leg A. Further, since the belt member 40 can be worn while reducing the surface directly pressing the lower leg A, it is possible to reduce discomfort and discomfort during wearing.

  Further, in the leg protector provided with the lower leg protection part 22 having the left and right covering flexible pieces 6a and 6a covering the lower leg side part D to the calf part F, at least the outer skin member 12 and the endothelial member 13 are used as constituent members. The left and right covered flexible piece portions 6a and 6a are laminated, and the width dimension of the inner skin member 13 in each of the left and right covered flexible piece portions 6a and 6a is smaller than the width dimension of the outer skin member 12. Since the cross-sectional shape of the left and right covering flexible piece portions 6a and 6a in the unmounted state is formed in an arcuate wrapping shape by setting and sewing in the vertical direction, it can be protected so as to surround the lower leg portion A. Moreover, not only the impact from the front but also the impact from the left and right direction can be mitigated. Further, since it is formed in an arc shape in a cross section in the unmounted state, the inner skin member 13 (the back fabric 8) can be easily attached so as to follow the lower leg A. In addition, since the belt member 40 can be worn with less contact with the crus A, local pressure can be reduced, and discomfort and discomfort during wearing can be reduced.
