パッド部材４０は、固定部３１から内方へ環状に延びる内周壁部４２と、中央に位置する、内周壁部４２に囲まれた内側開口（第１開口）４３とを有する。肌側シート５０は、固定部３１から内方へ環状に延びる内周壁部５２と、中央に位置する、内周壁部５２に囲まれた外側開口（第２開口）５３とを有する。接顔体３０の内周壁部３２は、前後方向Ｚにおいて互いに重なり合う、パッド部材４０の内周壁部４２と肌側シート５０の内周壁部５２とから形成されている。接顔体３０の中央開口３３は、パッド部材４０の内側開口４３と肌側シート５０の外側開口５３とが連通して形成されており、その開口縁３３ａは、肌側シート５０の外側開口５３の開口縁５３ａによって画成されている。 The pad member 40 has an inner peripheral wall portion 42 extending inward from the fixed portion 31 in an annular shape, and an inner opening (first opening) 43 located at the center and surrounded by the inner peripheral wall portion 42. The skin side sheet 50 has an inner peripheral wall portion 52 extending inward from the fixed portion 31 in an annular shape, and an outer opening (second opening) 53 located at the center and surrounded by the inner peripheral wall portion 52. The inner peripheral wall portion 32 of the face contact body 30 is formed of an inner peripheral wall portion 42 of the pad member 40 and an inner peripheral wall portion 52 of the skin side sheet 50 that overlap each other in the front-rear direction Z. The central opening 33 of the face contact body 30 is formed by communicating the inner opening 43 of the pad member 40 and the outer opening 53 of the skin side sheet 50, and the opening edge 33a is the outer opening 53 of the skin side sheet 50. It is defined by the opening edge 53a of.

パッド部材４０と肌側シート５０とは、前後方向Ｚにおいて互いに重なるように配置されていて、固定部３１を介してのみ接合されており、固定部３１から内方へ延びる内周壁部４２，５２は互いに接合されていない。したがって、パッド部材４０の内周壁部４２と肌側シート５０の内周壁部５２とは互いに分離されており、互いに干渉されることなく、自由に屈曲、変形させることができる。接顔体３０は、かかる構成を有することから、例えば、発泡弾性体層（内層）と、発泡弾性体層の後面全体に接着剤を介して接合された繊維不織布層（外層）との２層構造を有する従来の接顔体とは、その基本的構造が相違する。 The pad member 40 and the skin side sheet 50 are arranged so as to overlap each other in the front-rear direction Z, are joined only via the fixing portion 31, and the inner peripheral wall portions 42 , 52 extending inward from the fixing portion 31. Are not joined to each other. Therefore, the inner peripheral wall portion 42 of the pad member 40 and the inner peripheral wall portion 52 of the skin side sheet 50 are separated from each other, and can be freely bent and deformed without being interfered with each other. Since the face contact body 30 has such a configuration, for example, two layers of a foamed elastic body layer (inner layer) and a fibrous nonwoven fabric layer (outer layer) bonded to the entire rear surface of the foamed elastic body layer via an adhesive. Its basic structure is different from that of a conventional face-contact body having a structure.

肌側シート５０は、パッド部材４０の内側開口４３から径方向の内側へ延出して環状に延びる内側延出部５７を有し、内側延出部５７のうちの下方部分５７Ｂの面積は、上方部分５７Ａの面積よりも大きくなっており、また、下方部分５７Ｂの縦断中心線Ｐ上における上下方向Ｙの寸法Ｗ２は、上方部分５７Ａの縦断中心線Ｐ上における上下方向Ｙの寸法Ｗ１よりも大きくなっている。 The skin side sheet 50 has an inner extending portion 57 extending radially inward from the inner opening 43 of the pad member 40 and extending in an annular shape, and the area of the lower portion 57B of the inner extending portion 57 is upward. It is larger than the area of the portion 57A, and the dimension W2 in the vertical direction Y on the longitudinal center line P of the lower portion 57B is larger than the dimension W1 in the vertical direction Y on the longitudinal center line P of the upper portion 57A. It has become.

図４は、装着者が、大きな声で会話したり、大きく欠伸をする等して口４を比較的に大きく開いた状態における、マスク１０の様子を示している。反撥性材料のみからなる接顔体を備えた従来のマスクであっても、接顔体が顔面の起伏形状に沿って変形した状態でフィットされるので、高いシール性が発揮されて粉塵等がマスク内部に侵入するのを効果的に抑制しうる。したがって、通常の装着状態であればかかる従来のマスクであっても十分に内部の気密性を保つことができるが、突発的に、装着者が大きな声で会話したり、大きく欠伸をする等した場合には、接顔体が顔面（特に、下顎部）の急な動きに追従することができずに、接顔体と顔面との間に僅かな隙間が形成されて、装着感が損なわれて、装着者に不快感を与えるおそれがある。 Figure 4 is a wearer, large or talk with voice, in equal to opened mouth wide 4 relatively to the increased yawning, shows how the mask 10. Even with a conventional mask equipped with a face-contact body made of only a repulsive material, the face-contact body is fitted in a deformed state along the undulating shape of the face, so that high sealing performance is exhibited and dust and the like are removed. It can effectively suppress the invasion into the inside of the mask. Therefore, under normal wearing conditions, even with such a conventional mask, the internal airtightness can be sufficiently maintained, but suddenly, the wearer talks in a loud voice or makes a large stretch. In some cases, the face-contact body cannot follow the sudden movement of the face (particularly the lower jaw), and a slight gap is formed between the face-contact body and the face, which impairs the wearing comfort. This may cause discomfort to the wearer.

また、パッド部材４０の内側開口４３の面積は、肌側シート５０の外側開口５３の面積よりも大きいことから、肌側シート５０の内周壁部５２は、内側開口４３の開口縁４３ａよりも径方向の内側に延出する内側延出部５７を有する。したがって、マスク１０を装着したときに、肌側シート５０の前方に位置するパッド部材４０の内周壁部４２よりもさらに前方に内側延出部５７が位置し、かつ、柔軟に変形してパッド部材４０と顔面との間に入り込むような状態で顔面にフィットされる。 Further, since the area of the inner opening 43 of the pad member 40 is larger than the area of the outer opening 53 of the skin side sheet 50, the inner peripheral wall portion 52 of the skin side sheet 50 has a diameter larger than the opening edge 43a of the inner opening 43. It has an inner extending portion 57 extending inward in the direction. Therefore, when the mask 10 is attached, the inner extending portion 57 is located further forward than the inner peripheral wall portion 42 of the pad member 40 located in front of the skin side sheet 50, and the pad member is flexibly deformed and deformed. It fits on the face so that it fits between the 40 and the face.

切欠７０，７１は、パッド部材４０の横方向Ｘの両側に一対のみ配置されているが、このように横方向Ｘにおいて対向する一対の切欠が、上下方向Ｙにおいて間隔を空けて並ぶように複数配置されていてもよい。 Only a pair of notches 70 and 71 are arranged on both sides of the pad member 40 in the lateral direction X, and a plurality of notches facing each other in the lateral direction X are arranged so as to be spaced apart from each other in the vertical direction Y. It may be arranged.
