To support a lower jaw using a lower jaw supporting tool which can be easily worn, does not become uncomfortable even when worn during sleeping, and can support the lower jaw while allowing some movement, and Method.SOLUTION: The lower jaw support tool is formed of a series of rod-like members, and includes an annular base portion 110 which is partially opened, a first support portion which supports the central portion of the lower jaw, a second support which supports the lower jaw side portion Section. This first support portion is constituted by the left side first support material 121 and the right side first support material 122, and is elastically deformed following the upward and downward movement of the lower jaw. The lower end of the opening of the base portion, the lower end of the first support portion, the upper end of the first support portion and the front end of the second support member are connected to form the lower jaw support. With this structure, when the base portion is placed on the shoulder, the first support portion is disposed below the central portion of the lower jaw and the second support portion is arranged along the lower jaw side portion.(FIG.【課題】手軽に装着できて、睡眠時に装着しても不快となることがなく、しかも多少の動きを許容しつつ下顎を支持することができる下顎支持具と、これを用いて下顎を支持する方法を提供する。【解決手段】下顎支持具は、一連の棒状部材で形成されるものであり、一部開口した環状の基礎部110と、下顎中央部を支える第1支持部、下顎側部を支える第2支持部を備えたものである。この第1支持部は、左側第1支持材121と右側第1支持材122で構成されており、下顎の上下移動に追随して弾性変形する。基礎部の開口部端と第1支持部の下端、第1支持部の上端と第2支持材の前方端が接続されて、下顎支持具は形成される。この構造により、基礎部を肩上に載置すると第1支持部は下顎中央部の下方に、第2支持部は下顎側部に沿って配置される。【選択図】図2
