On the other hand, by applying the elastic adhesive material 3 using a rubber material or an elastic resin material, preferably a silicon rubber material 3s, to the surface of the tubular covering portion 2, the pressure as shown in FIGS. 2 and 3 is applied. The pattern portion 4 is provided. 2 and 3 show a state in which the tubular covering portion 2 (supporter for hallux valgus 1t) is folded flat (crushed), FIG. 2 shows the left side surface side (thumb side), and FIG. 3 shows the right side surface side. (Pinky side) is shown. Therefore, the right side surface portion of the compression pattern portion 4 appearing in FIG. 3 and the left side surface portion of the compression pattern portion 4 appearing in FIG. 2 form a single pattern continuously formed.

The pressure-applying pattern portion 4 basically sets the coating density R of the elastic adhering material 3 in stages corresponding to different coating areas Xa, Xbp, Xbq ... Set for the entire area to which the elastic adhering material 3 is applied. By making them different from each other, a predetermined distribution pattern related to the magnitude of the contact pressure Fm ... applied to the portion of the human body H corresponding to the application areas Xa, Xbp, Xbq ... Is set. In this case, there are four types of compression parts, that is, the strong pressure portion 4a having the largest pressure Fm, the middle top pressure portion 4b having the second largest pressure Fm, depending on the size of the pressure Fm. It is equipped with a middle and lower pressure section 4c with a large contact pressure Fm, and a weak compression section 4d with a fourth large contact pressure Fm, and a predetermined contact pressure Fm ...

Further, as for the shape of the pressure-applying pattern portion 4, as shown in FIGS. 2 and 3, the coating area Xa is arranged on the side surface of the tubular covering portion 2 on the side where the thumb mounting portion 11 is provided, and the coating area Xa is arranged. The coating areas Xbp, Xbq, the coating areas Xcp, Xcq, and the coating areas Xdp, Xdq are sequentially arranged on both sides in the circumferential direction. As a result, the overall shape of the pressure pattern portion 4 becomes an elongated strip shape, one coating area Xbp, Xcp, Xdp is positioned on the upper side, and the other coating area Xbq, Xcq, Xdq is positioned on the lower side. The coating areas Xdp and Xdq are located near the little finger Hfs as shown in FIG. Further, the coating areas Xcp and Xcq are formed in an elongated shape, and one end side is located near the coating area Xa and is located on the front end side, and the other end side is located near the little finger Hfs and is located on the rear end side. Let me. Then, the coating areas Xbp and Xbq are arranged between the coating area Xa and the coating area Xcp, and between the coating area Xa and the coating area Xcq, respectively, and the coating area Xdp is arranged in the region on the little finger Hfs side with respect to the coating areas Xcp and Xcq. , Xdq are arranged respectively.

In this case, in the pressure pattern portion 4, the strong pressure portion 4a is located on the side surface on the thumb Hft side, and the pressure Fm ... , The contact pressure Fm ... is distributed as shown by the virtual line Kf in FIG. 5, and the side surface on the thumb Hft side is pressurized in the arrow Dq direction and at the same time pulled backward in the arrow Dr direction. Works.

Further, as shown in FIG. 6, at the position Pp in the anteroposterior direction on the side surface on the thumb Hft side, the contact pressure Fqm, which is relatively maximum in the anteroposterior direction, acts on the thumb Hft side and the little finger Hfs side. At the position Pq on the side surface, which is offset rearward by the width Lr with respect to the position Pp, the contact pressure Fpm, which is relatively maximum in the front-rear direction, acts on the little finger Hfs side.

As a result, the pressure pattern portion 4 pressurizes the position near the metatarsophalangeal joint, and as a result, the thumb Hft is corrected in the opposite direction, that is, in the direction of the arrow De away from the second finger. To. That is, prevention (or improvement) of hallux valgus can be effectively achieved.

As described above, the valgus supporter 1t according to the present embodiment is formed by applying the elastic adhering material 3 (silicon rubber material 3s) to the surface of the tubular covering portion 2 as a basic configuration, and the elastic adhering material 3 is formed. By gradually changing the coating density R of the elastic adhering material 3 corresponding to the different coating areas Xa, Xbp, Xbq ... Set for the entire area to be coated, the coating areas Xa, Xbp, Xbq ...
