Description

  The present invention relates to an ankle supporter to be attached to an ankle joint part of a body.

Conventionally, for example, supporters have been widely used for fixing, supporting, compressing, or keeping warm the knee and elbow of the body. As such a supporter, there is one proposed in Patent Document 1, for example. This supporter has a core material having a modulus larger than that of the elastic material forming the main body on a part of the surface of the main body (supporter main body) made of the elastic material formed in a cylindrical shape, and the elongation of the core material. A reinforcing material formed by laminating a surface material that restricts the above is adhered, and the modulus of the reinforcing material is set to a size that can restrict the movement of the affected area within the range of motion. As a result, in normal daily living conditions with little changes in muscles and ligaments, the body structure can be followed only by changes, and when the movement is intense, the elasticity of the reinforcing material is added due to the change in the body only and strong. Stress acts to suppress further muscle and ligament movement.
