PROBLEM TO BE SOLVED: To provide a band length adjustment body of face fittings in which the interference due to flapping of a band end is eliminated, and further the length adjustment of the band can easily be operated, and furthermore, a configuration is simple and the production cost can also be reduced.SOLUTION: A band length adjustment body of face fittings is characterized as follows: a frame body 1 comprises upper lower frames and a back frame 1c made of hard resin a first partition frame 2 and a second partition frame 3 are integrally provided from the back frame side of this frame body a space between the back frame and the first partition frame is a first insertion space S1 of a band B a space between the first partition frame and the second partition frame is a second insertion space S2 of the band B a connecting body of the band B is installed between the upper lower frames in an open end of the frame body the band B is inserted and drawn outwardly from the inside of the first insertion space S1 the band B is inserted and drawn inwardly from the outside of the second insertion space S2 further, the band B is inserted and drawn outwardly from the inside of a band insertion hole h of the end of the face fittings and the end of this band B is connected with the connecting body.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT【課題】バンドの端部がばたついて邪魔になることはなく、さらにバンドの長さ調節の操作がし易く、しかも構造が簡単で、生産コストも削減することができる顔面装着具のバンド長さ調節体を提供する。【解決手段】硬質樹脂製の上下枠と後枠1cよりなる枠体1とし、この枠体の後枠側から第一仕切り枠2及び第二仕切り枠3を一体に設けたものとし、後枠と第一仕切り枠の間を、バンドBの第一挿通空間S1とし、第一仕切り枠と第二仕切り枠の間を、バンドBの第二挿通空間S2とし、枠体の開放端において、上下枠の間に、バンドBの連結体を取り付け、第一挿通空間S1の内方からバンドBを挿通して外方に引き出し、第二挿通空間S2の外方からバンドBを挿通して内方に引き出し、さらに顔面装着具の端部のバンド挿通孔hの内方からバンドBを挿通して外方に引き出し、このバンドBの端部を連結体に連結した。【選択図】図7
