  • Patent number: 10864101
    Abstract: A garment, containing a tubular joint supporter section, the section including: a central region in an axial direction of the tubular joint supporter section, which includes a wear pressure applying region for applying wear pressure to a joint site of a body, a one-end side region positioned at one end, and an other-end side region positioned at another end side, in which the wear pressure of the wear pressure applying region is higher than an average wear pressure of the one-end and other-end side regions, and regions other than the wear pressure applying region in the section include a concave-convex structure region formed from a concave-convex structure; and a knee supporter, in which an average wear pressure A of the knee support section is higher than an average wear pressure B of the thigh side support section and the shin side support section.

  • Publication number: 20200129682
    Abstract: A supporter for body (1) to be attached to a skin of a body includes a pad base member (10) which is made of an elastic member and has a curved shape at least locally, and an adhesion layer (11) which is provided in a surface of the pad base member (10) on a side being adhered to the skin. The adhesion layer (11) is adhered to the skin with the curved shape of the pad base member (10) being stretched along a shape of the body, and holds the skin in a state in which the skin is drawn up, using a restoring force of the pad base member (10).
