PROBLEM TO BE SOLVED: To solve the problems that: since a conventional supporter pushes and contacts upper and lower limbs by a planar structure, it is hard to locally change a push and contact degree and stuffiness is caused due to pushing by a plane.SOLUTION: A supporter is formed of a plurality of string parts 10 forming a plurality of pressers 12 at every proper interval, and a retainer plate 20 having a plurality of fixation grooves M for engaging the string parts 10 independently. One end of each of the plurality of string parts 10 is engaged with each of the fixation grooves M of the retainer plate 20, using the pressers 12 of the string parts 10, and the other ends of the plurality of string parts 10 are wound around the upper and lower limbs like a bandage. According to a thickness of each of the upper and lower limbs, any of the pressers 12 of the string parts 10 is engaged with the fixation groove M of the retainer plate so that each of the string parts 10 compresses and holds the upper and lower limbs at a push and contact degree according to the thickness of each of the upper and lower limbs.SELECTED DRAWING: Figure 2
