また、実施形態の顔面装着具によれば、ヘッドベルト２が、第１挿通孔６０及び第２挿通孔７０の２つの挿通孔を具備することによって、ループ部５０近傍におけるヘッドベルト２の形状を直線的に伸びる形状に整えることが容易になり、顔面装着具の着脱を容易にできるとともに、装着感を向上させることができる。 Further, according to the face attachment device of the embodiment, the head belt 2 has two insertion holes, the first insertion hole 60 and the second insertion hole 70, so that the shape of the head belt 2 near the loop portion 50 can be adjusted. It becomes easy to adjust the shape to extend linearly, and the attachment and detachment of the face attachment can be facilitated, and the feeling of wearing can be improved.

また、実施形態の顔面装着具によれば、ストッパ部８０が、ループ部５０に設けられることによって、ヘッドベルト２をベルト取付部４に取付ける際に、ヘッドベルト２が、ループ部５０を超える位置までベルト取付部４に挿通されることを防止できる。従って、ヘッドベルト２における一定の位置でヘッドベルト２を装着具本体１に連結でき、ベルト取付部４に対するヘッドベルト２の取付けを容易にできる。 Further, according to the face attachment device of the embodiment, the stopper portion 80 is provided in the loop portion 50 so that when the head belt 2 is attached to the belt attachment portion 4 , the head belt 2 is positioned beyond the loop portion 50 . It is possible to prevent the belt attachment portion 4 from being inserted up to. Therefore, the head belt 2 can be connected to the attachment main body 1 at a fixed position on the head belt 2, and the head belt 2 can be easily attached to the belt attachment portion 4. FIG.

また、実施形態の顔面装着具によれば、第１挿通孔６０と第２挿通孔７０との間に厚板部９０が形成されることによって、ループ部５０の近傍でヘッドベルト２が二重に重なる部分を直線的に伸びる形状に整えることが容易となり、顔面装着具の着脱を更に容易にできるとともに、装着感を更に向上させることができる。 Further, according to the face attachment device of the embodiment, the thick plate portion 90 is formed between the first insertion hole 60 and the second insertion hole 70 , so that the head belt 2 is doubled in the vicinity of the loop portion 50 . It becomes easy to adjust the portion overlapping with the face so as to extend linearly, so that the attachment and detachment of the face attachment can be further facilitated, and the feeling of wearing can be further improved.

また、実施形態の顔面装着具によれば、重なり部１００が、比較的に幅広に形成されることによって、ヘッドベルト２において、使用者のこめかみに当接する部分の面積を大きくでき、接触圧力を小さくし、装着感を更に向上できる。 In addition, according to the face attachment device of the embodiment, since the overlapped portion 100 is formed relatively wide, the area of the portion of the head belt 2 that contacts the temples of the user can be increased, and the contact pressure can be reduced. It can be made smaller and the feeling of wearing can be further improved.

また、実施形態の顔面装着具によれば、被連結部１１０が、全体的に幅広に形成されていることによって、面同士の摩擦力によってヘッドベルト２をバックル３に連結するとき、より大きな摩擦力を発揮でき、十分な強度でヘッドベルト２をバックル３に連結できる。 In addition, according to the face attachment device of the embodiment, since the connecting part 110 is formed to have a wide width as a whole, when the head belt 2 is connected to the buckle 3 due to the frictional force between the surfaces, the friction is greater. The head belt 2 can be connected to the buckle 3 with sufficient strength.

また、反対に、ヘッドベルト２における被連結部１１０以外の部分の幅を被連結部１１０よりも小さくすることによって、顔面装着具の着脱の際に、より小さな力でヘッドベルト２を伸縮でき、ヘッドベルト２が、顔面装着具の固定に必要十分な弾性力を発揮できる長さの範囲を広げることができ、ヘッドベルト２の長さ調節を容易にできる。従って、必要十分な弾性力で顔面装着具を使用者の頭部に固定することが容易となり、顔面装着具の着脱を更に容易にできる。 Conversely, by making the width of the portion of the head belt 2 other than the connected portion 110 smaller than the width of the connected portion 110, the head belt 2 can be stretched and contracted with a smaller force when attaching and detaching the face attachment. The range of length in which the head belt 2 can exhibit necessary and sufficient elastic force for fixing the face attachment can be widened, and the length adjustment of the head belt 2 can be facilitated. Therefore, it becomes easy to fix the face fitting to the user's head with a necessary and sufficient elastic force, and the attachment and detachment of the face fitting can be further facilitated.

次に、図４～図７を参照して、バックル３を説明する。図４は、実施形態に係る顔面装着具用バックルを示す斜視図である。図５は、図４の顔面装着具用バックルを示す正面図である。図６は、図４の顔面装着具用バックルの分解斜視図である。図７は、図４の顔面装着具用バックルの動作を示す平面図である。 Next, the buckle 3 will be described with reference to FIGS. 4 to 7. FIG. FIG. 4 is a perspective view showing the buckle for facial equipment according to the embodiment. FIG. 5 is a front view showing the face attachment buckle of FIG. 4. FIG. 6 is an exploded perspective view of the buckle for the face attachment of FIG. 4. FIG. FIG. 7 is a plan view showing the operation of the buckle for the face attachment of FIG. 4. FIG.

図４、図５に示すように、バックル３のプラグ１０は、円形の凸部１１が突設された係止片１２と、台板部１３と、支持部１４と、受付部１５と、第１連結部１６と、回転規制部１７とを有する。 As shown in FIGS. 4 and 5, the plug 10 of the buckle 3 includes a locking piece 12 having a circular convex portion 11 projecting therefrom, a base plate portion 13, a support portion 14, a receiving portion 15, and a second It has a 1 connecting portion 16 and a rotation restricting portion 17 .

バックル３のソケット２０は、円形の凹部２１が形成されている被係止部２２と、台板当接部２３と、周壁部２４と、第２連結部２５と、被規制部２６とを有する。凹部２１は、実施形態においては、板状の被係止部２２を貫通する貫通孔であり、プラグ１０を枢支可能に、凸部１１と嵌合する。すなわち、凸部１１と凹部２１とが嵌合することによって、プラグ１０は、所定の角度範囲で回動可能に、ソケット２０と連結される。 The socket 20 of the buckle 3 has a locked portion 22 in which a circular recess 21 is formed, a base plate contact portion 23, a peripheral wall portion 24, a second connecting portion 25, and a restricted portion 26. . In the embodiment, the recessed portion 21 is a through hole penetrating the plate-shaped locked portion 22 and is fitted with the projecting portion 11 so as to pivotally support the plug 10 . That is, by fitting the convex portion 11 and the concave portion 21, the plug 10 is connected to the socket 20 so as to be rotatable within a predetermined angular range.

実施形態においては、バックル３は、ポリカーボネート、ナイロン、ポリエステル、及びＡＢＳ樹脂等の硬質プラスチックから形成されている。バックル３が、硬質プラスチックから形成されることによって、プラグ１０とソケット２０とを連結するときに、音や感触によって、凸部１１と凹部２１とが嵌合したことを明瞭に感知でき、顔面装着具の着脱を更に容易にできる。 In embodiments, the buckle 3 is formed from rigid plastics such as polycarbonate, nylon, polyester, and ABS resin. Since the buckle 3 is made of hard plastic, when the plug 10 and the socket 20 are connected, it can be clearly sensed by sound and touch that the projection 11 and the recess 21 are fitted to each other. Attachment and detachment of tools can be made easier.

プラグ１０の凸部１１は、突出方向Ｘ１からの平面視形状が円形である。図５に示すように、凸部１１の突出方向Ｘ１は、ソケット２０にプラグ１０を差込むときの差込方向Ｘ３と交差する方向である。また、凸部１１は、差込方向Ｘ３に向かって突出高さが小さくなるように、頂面が傾斜している。 The convex portion 11 of the plug 10 has a circular shape in plan view from the projecting direction X1. As shown in FIG. 5 , the projecting direction X1 of the projection 11 is a direction that intersects the insertion direction X3 when the plug 10 is inserted into the socket 20 . Moreover, the top surface of the protrusion 11 is inclined so that the protrusion height decreases in the insertion direction X3.

凸部１１の頂面が、差込方向Ｘ３に向かって突出高さが小さくなるように傾斜していることによって、プラグ１０をソケット２０に差し込むとき、スムーズに凸部１１と凹部２１とを嵌合できる。反対に、凸部１１は、プラグ１０をソケット２０から引き抜くときの引抜方向Ｘ４に向かって突出高さが大きくなっている。従って、凸部１１と凹部２１との嵌合によって、十分な強度でプラグ１０をソケット２０に係止できる。 Since the top surface of the protrusion 11 is inclined so that the protrusion height becomes smaller in the insertion direction X3, when the plug 10 is inserted into the socket 20, the protrusion 11 and the recess 21 are smoothly fitted. can be combined. On the contrary, the protruding portion 11 has a larger projection height in the pulling-out direction X4 when the plug 10 is pulled out from the socket 20 . Therefore, by fitting the protrusion 11 and the recess 21, the plug 10 can be locked to the socket 20 with sufficient strength.

プラグ１０の係止片１２は、図５、図６に示すように、平面視形状が卵形であり、第１基端部としての基端部１２ａと、中間部１２ｂと、第１先端部としての先端部１２ｃとを有する。基端部１２ａは、支持部１４に連結される部分である。中間部１２ｂは、基端部１２ａと先端部１２ｃとの間の部分であり、凸部１１が突設される。先端部１２ｃは、係止片１２の自由端部である。 As shown in FIGS. 5 and 6, the locking piece 12 of the plug 10 has an oval shape in plan view, and includes a base end portion 12a as a first base end portion, an intermediate portion 12b, and a first tip portion. and a tip portion 12c. The base end portion 12a is a portion connected to the support portion 14 . The intermediate portion 12b is a portion between the proximal end portion 12a and the distal end portion 12c, and the convex portion 11 protrudes therefrom. The tip 12c is a free end of the locking piece 12. As shown in FIG.

プラグ１０の台板部１３は、係止片１２に対し凸部１１の突出方向Ｘ１と反対方向Ｘ２に配設される。実施形態においては、台板部１３は、係止片１２との間に所定の隙間を空けて、係止片１２に対し反対方向Ｘ２に配設される円形の板状部材である。 The base plate portion 13 of the plug 10 is arranged in a direction X2 opposite to the projecting direction X1 of the projection 11 with respect to the locking piece 12 . In the embodiment, the base plate portion 13 is a circular plate-like member arranged in the opposite direction X2 to the locking piece 12 with a predetermined gap between it and the locking piece 12 .

プラグ１０の支持部１４は、図４、図６に示すように、凸部１１と凹部２１とが嵌合する嵌合状態に、係止片１２を台板部１３に弾性支持する。すなわち、実施形態においては、係止片１２は、基端部１２ａにおいて、支持部１４によって片持ち支持される。 As shown in FIGS. 4 and 6, the support portion 14 of the plug 10 elastically supports the locking piece 12 to the base plate portion 13 in a fitted state in which the convex portion 11 and the concave portion 21 are fitted. That is, in the embodiment, the locking piece 12 is cantilevered by the support portion 14 at the proximal end portion 12a.

プラグ１０の受付部１５は、係止片１２において凸部１１よりも先端部１２ｃ寄りの位置に形成されており、係止片１２を反対方向Ｘ２に押圧する押圧操作であって、凸部１１と凹部２１との嵌合状態を解除するための押圧操作を受付ける。実施形態においては、係止片１２の先端部１２ｃにおける突出方向Ｘ１側の面に受付部１５が形成されている。また、受付部１５は、滑り止めのための複数の突条１５ａを有している。以上のとおり、実施形態のバックル３は、係止片１２を突出方向Ｘ１の反対方向Ｘ２に押圧することによって嵌合状態が解除されるフロントリリース式である。 The receiving portion 15 of the plug 10 is formed at a position closer to the tip portion 12c of the locking piece 12 than the convex portion 11, and the pressing operation of pressing the locking piece 12 in the opposite direction X2 causes the convex portion 11 to be pushed. and the concave portion 21 are pressed to release the fitted state. In the embodiment, the reception portion 15 is formed on the surface of the front end portion 12c of the locking piece 12 on the projecting direction X1 side. Moreover, the receiving part 15 has a plurality of protrusions 15a for slip prevention. As described above, the buckle 3 of the embodiment is a front release type in which the fitted state is released by pressing the locking piece 12 in the direction X2 opposite to the projecting direction X1.

プラグ１０の第１連結部１６は、図４、図５に示すように、台板部１３と一体的に形成されており、プラグ１０にヘッドベルト２を連結する。また、第１連結部１６は、ヘッドベルト２の長さ調節機構としての複数本のバー部材１６ａ、１６ｂ、１６ｃを有する。 The first connecting portion 16 of the plug 10 , as shown in FIGS. 4 and 5 , is formed integrally with the base plate portion 13 and connects the head belt 2 to the plug 10 . The first connecting portion 16 also has a plurality of bar members 16a, 16b, and 16c as a length adjusting mechanism for the head belt 2. As shown in FIG.

複数本のバー部材１６ａ、１６ｂ、１６ｃは、互いに平行に、所定の間隔を置いて第１連結部１６に配設されており、ヘッドベルト２と摩擦係合可能である。すなわち、ヘッドベルト２のベルト先端部４０が、例えば図５に矢印付きの曲線Ａに示されている経路で複数本のバー部材１６ａ、１６ｂ、１６ｃの間を挿通されることによって、ヘッドベルト２の被連結部１１０と第１連結部１６とが摩擦係合され、プラグ１０とヘッドベルト２とが、ヘッドベルト２の長さを調節自在に連結される。 A plurality of bar members 16a, 16b, and 16c are arranged parallel to each other at a predetermined interval on the first connecting portion 16, and are frictionally engageable with the head belt 2. As shown in FIG. That is, the belt tip 40 of the head belt 2 is passed through the plurality of bar members 16a, 16b, and 16c along the path indicated by arrowed curve A in FIG. The connected portion 110 and the first connecting portion 16 are frictionally engaged, and the plug 10 and the head belt 2 are connected so that the length of the head belt 2 can be adjusted.

プラグ１０の回動規制部１７は、図５、図６に示すように、台板部１３の両側部に突設されており、図７に示すように、プラグ１０がソケット２０に対し回動する回動範囲を規制可能に、ソケット２０と当接する。実施形態においては、プラグ１０は、円形の凸部１１の中心を通る中心軸周りに回動し、回動規制部１７によって、左右の最大回動位置Ｌ２、Ｌ３が規制される。 5 and 6, the rotation restricting portions 17 of the plug 10 protrude from both sides of the base plate portion 13. As shown in FIG. It abuts on the socket 20 so as to be able to regulate the rotation range. In the embodiment, the plug 10 rotates around a central axis passing through the center of the circular convex portion 11 , and the left and right maximum rotation positions L2 and L3 are restricted by the rotation restricting portion 17 .

実施形態においては、左右の最大回動位置Ｌ２、Ｌ３と、プラグ１０の中立位置Ｌ１との間の最大回動角度α１、α２は、等しい角度である。また、最大回動角度α１、α２は、鋭角であればよいが、４５°以下の角度であることが好ましく、２０°以下の角度であることがより好ましく、５°から１０°の角度であることが更に好ましい。 In the embodiment, the maximum rotation angles α1 and α2 between the left and right maximum rotation positions L2 and L3 and the neutral position L1 of the plug 10 are equal. Further, the maximum rotation angles α1 and α2 may be acute angles, but are preferably angles of 45° or less, more preferably angles of 20° or less, and angles of 5° to 10°. is more preferred.

ソケット２０の被係止部２２は、ソケット２０にプラグ１０が差込まれているとき、プラグ１０の係止片１２に当接する。ソケット２０の台板当接部２３は、ソケット２０にプラグ１０が差込まれているとき、プラグ１０の台板部１３に当接する。ソケット２０の周壁部２４は、ソケット２０にプラグ１０が差込まれているとき、プラグ１０の支持部１４を囲うように支持部１４と対向する。 The locked portion 22 of the socket 20 contacts the locking piece 12 of the plug 10 when the plug 10 is inserted into the socket 20 . The base plate contact portion 23 of the socket 20 contacts the base plate portion 13 of the plug 10 when the plug 10 is inserted into the socket 20 . The peripheral wall portion 24 of the socket 20 faces the support portion 14 so as to surround the support portion 14 of the plug 10 when the plug 10 is inserted into the socket 20 .

ソケット２０の第２連結部２５は、ソケット２０とヘッドベルト２とを連結するものであり、ヘッドベルト２の長さを調節する長さ調節機構を有している。また、図４、図５に示すように、第２連結部２５は、台板当接部２３と一体形成されており、複数本のバー部材２５ａ、２５ｂ、２５ｃを有する。被規制部２６は、プラグ１０がソケット２０に対し回動する回動範囲を規制可能に、回動規制部１７に当接される。 The second connecting portion 25 of the socket 20 connects the socket 20 and the head belt 2 and has a length adjusting mechanism for adjusting the length of the head belt 2 . Moreover, as shown in FIGS. 4 and 5, the second connecting portion 25 is integrally formed with the base plate contact portion 23, and has a plurality of bar members 25a, 25b, and 25c. The restricted portion 26 abuts on the rotation restricting portion 17 so as to restrict the rotation range in which the plug 10 rotates with respect to the socket 20 .

以上、図１～図２と、図４～図７とを参照して説明したように、本実施形態の顔面装着具及び顔面装着具用バックルによれば、円形の凸部１１と円形の凹部１２との嵌合によって、プラグ１０とソケット２０とが連結される。従って、プラグ１０とソケット２０との向きが一直線上ではなく、多少斜めであっても、プラグ１０をソケット２０に差し込むことができ、後頭部において、プラグ１０とソケット２０とを連結する連結作業が容易となる。 As described above with reference to FIGS. 1 to 2 and FIGS. 4 to 7, according to the face-mounting device and the face-mounting device buckle of the present embodiment, the circular convex portion 11 and the circular concave portion 12 connects the plug 10 and the socket 20 together. Therefore, even if the directions of the plug 10 and the socket 20 are not in a straight line but slightly oblique, the plug 10 can be inserted into the socket 20, and the work of connecting the plug 10 and the socket 20 at the back of the head is easy. becomes.

また、本実施形態の顔面装着具及び顔面装着具用バックルによれば、係止片１２が、凸部１１よりも先端部１２ｃ寄りの位置に受付部１５を有することによって、梃子の原理によって、より小さな力で凸部１１と凹部２１との嵌合状態を解除でき、顔面装着具の着脱を更に容易にできる。また、より小さな力で凸部１１と凹部２１との嵌合状態を解除できることによって、支持部１４が係止片１２を弾性支持する支持力を大きくしても、凸部１１と凹部２１との嵌合状態を容易に解除できる。従って、より大きな支持力を発揮するように支持部１４を設計でき、プラグ１０とソケット２０との結合強度を更に大きくできる。 In addition, according to the face-mounting device and the face-mounting device buckle of the present embodiment, the locking piece 12 has the receiving portion 15 at a position closer to the tip portion 12c than the convex portion 11, and according to the principle of leverage, The fitting state between the convex portion 11 and the concave portion 21 can be released with a smaller force, and the attachment and detachment of the face attachment can be further facilitated. In addition, since the fitting state between the convex portion 11 and the concave portion 21 can be released with a smaller force, even if the supporting force for elastically supporting the locking piece 12 by the supporting portion 14 is increased, the convex portion 11 and the concave portion 21 can be disengaged. The fitted state can be easily released. Therefore, the support portion 14 can be designed to exert a greater support force, and the coupling strength between the plug 10 and the socket 20 can be further increased.

また、凸部１１と凹部２１との嵌合状態は、例えば、凹部２１を通して指で凸部１１を押圧することによっても解除可能である。しかしながら、凹部２１の径が小さければ、凹部２１に指を通し、凸部１１を押圧することはできない。実施形態によれば、係止片１２が受付部１５を有することによって、凹部２１の径が小さく、凸部１１を指で押圧できないときにも、受付部１５に対し押圧操作し、凸部１１と凹部２１との嵌合状態を解除できる。従って、凹部２１を小さな径に設計しても、不都合がなく、バックル３を容易に小型化できる。 Further, the fitting state between the convex portion 11 and the concave portion 21 can be released by pressing the convex portion 11 through the concave portion 21 with a finger, for example. However, if the diameter of the concave portion 21 is small, the finger cannot be passed through the concave portion 21 to press the convex portion 11 . According to the embodiment, since the engaging piece 12 has the receiving portion 15, even when the diameter of the concave portion 21 is small and the convex portion 11 cannot be pressed with a finger, the receiving portion 15 can be pressed and the convex portion 11 can be pressed. and the recessed portion 21 can be released. Therefore, even if the concave portion 21 is designed to have a small diameter, the buckle 3 can be easily miniaturized without any inconvenience.

また、本実施形態の顔面装着具及び顔面装着具用バックルによれば、最大回動角度α１、α２が上記の範囲であることによって、顔面装着具の装着時におけるヘッドベルト２のずれを効果的に防止できる。例えば、水中への飛び込みや競泳のスタート時における顔面装着具の脱落、ずれ、並びに装着具本体１における水漏れを防ぐために、使用者の後頭部において、眼よりも上の位置にヘッドベルト２を掛けると、バックル３の両端に下向きの力が掛かる。一般的なフック式のバックルや、サイドリリース式のバックルであれば、プラグとソケットとが一直線上に並んだ状態で固定されるために、バックル３が下にずれやすくなる。実施形態のバックル３によれば、後頭部におけるバックル３の位置に応じて、プラグ１０とソケット２０との相対角度が変化することによって、バックル３のずれを効果的に防止でき、顔面装着具の脱落、ずれを効果的に防止できる。 In addition, according to the face attachment and the buckle for the face attachment of the present embodiment, since the maximum rotation angles α1 and α2 are within the above ranges, the deviation of the head belt 2 when wearing the face attachment can be effectively prevented. can be prevented. For example, the head belt 2 is hung on the back of the user's head at a position above the eyes in order to prevent the face fitting from coming off or slipping and water leakage from the fitting main body 1 when jumping into water or starting a swimming race. , a downward force is applied to both ends of the buckle 3 . In the case of a general hook-type buckle or a side-release type buckle, the buckle 3 tends to slide downward because the plug and the socket are fixed in a straight line. According to the buckle 3 of the embodiment, since the relative angle between the plug 10 and the socket 20 changes according to the position of the buckle 3 on the back of the head, it is possible to effectively prevent the buckle 3 from slipping, thereby preventing the face attachment from coming off. , can effectively prevent deviation.

また、例えば、使用者が、顔面装着具を装着している状態で、装着具本体１を額まで移動するとき、プラグ１０とソケット２０との相対的な回動によって、装着具本体１を額までスムーズに移動できる。 Further, for example, when the user wears the face attachment and moves the attachment main body 1 to the forehead, the relative rotation between the plug 10 and the socket 20 moves the attachment main body 1 to the forehead. You can move smoothly to

反対に、最大回動角度α１、α２が上記の範囲であることによって、プラグ１０とソケット２０との相対的な回動角度が大きくなり過ぎることを防止でき、凸部１１と凹部２１との嵌合状態が解除されやすくなることを防止でき、安定的に顔面装着具を頭部に固定できる。すなわち、凸部１１の頂面が、Ｘ３に向かって突出高さが小さくなるように傾斜しているとき、プラグ１０がソケット２０に対し大きな角度で回動すると、凸部１１と凹部２１との嵌合状態は解除されやすくなる。最大回動角度α１、α２を上記の範囲に設定することによって、例えば装着具本体１を額まで移動するときにも、プラグ１０とソケット２０との相対角度が大きくなり過ぎることを防止でき、凸部１１と凹部２１との嵌合状態が解除されやすくなることを防止できる。 On the contrary, by setting the maximum rotation angles α1 and α2 within the above ranges, it is possible to prevent the relative rotation angle between the plug 10 and the socket 20 from becoming too large, and the fitting between the projection 11 and the recess 21 can be prevented. It is possible to prevent the mated state from being easily released, and to stably fix the face attachment to the head. That is, when the top surface of the protrusion 11 is inclined toward X3 so that the protrusion height becomes smaller, when the plug 10 rotates at a large angle with respect to the socket 20, the protrusion 11 and the recess 21 The mated state is easily released. By setting the maximum rotation angles α1 and α2 within the above range, it is possible to prevent the relative angle between the plug 10 and the socket 20 from becoming too large even when the attachment main body 1 is moved to the forehead, for example. It is possible to prevent the fitting state between the portion 11 and the concave portion 21 from being easily released.

The glass body 1A has a pair of colored lens portions 1a, a lens frame portion 1b, and a nose pad 1e. In the embodiment, the pair of lens portions 1a are integrally formed and formed from a single curved resin plate or glass plate. The pair of lens portions 1a may be formed separately, or may be connected to each other by a nose bridge (not shown) or the like.

また、グラス本体１Ａは、両端に、ヘッドベルト２が挿通可能であるベルト取付部４を有する。使用者は、ベルト取付部４にヘッドベルト２を挿通し、ヘッドベルト２をグラス本体１Ａに取り付ける。本実施形態におけるグラス本体１Ａ以外の構成は、図１～図７に示す実施形態の構成と同様である。 Further, the glass body 1A has belt attachment portions 4 at both ends through which the head belt 2 can be inserted. The user inserts the head belt 2 through the belt attachment portion 4 and attaches the head belt 2 to the glass body 1A. The configuration of this embodiment other than the glass body 1A is the same as the configuration of the embodiment shown in FIGS.

以上、図８を参照して説明したように、本実施形態の顔面装着具は、サングラスであり、グラス本体１Ａが、両端に、ヘッドベルト２が挿通可能であるベルト取付部４を有しており、本発明は、ゴーグルだけではなく、サングラスを含む眼鏡一般に適用可能である。 As described above with reference to FIG. 8, the face attachment device of the present embodiment is sunglasses, and the glass body 1A has belt attachment portions 4 at both ends through which the head belt 2 can be inserted. Therefore, the present invention is applicable not only to goggles but also to spectacles in general including sunglasses.

以上、図面（図１～図８）を参照しながら本発明の実施形態を説明した。但し、本発明は、上記の実施形態に限られるものではなく、その要旨を逸脱しない範囲で種々の態様において実施することが可能である（例えば、下記（１）～（２））。 The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 8).
