近年、例えば、ユニットバスを用いた浴室の下方空間を気密・断熱構造として省エネ化を図ることが行われている。具体的には、コンクリート製の布基礎で囲まれた浴室の下方空間内への通気を遮断するとともに、布基礎の内壁に断熱材を張りめぐらせることにより、気密性及び断熱性を高めている。このとき、布基礎には床下を点検するための人通口又は点検口（基礎点検口）を設ける必要がある。 In recent years, for example, efforts have been made to save energy by making the lower space of a bathroom using a unit bath an airtight and heat-insulating structure. Specifically, airtightness and heat insulation are improved by blocking ventilation to the lower space of the bathroom surrounded by a concrete foundation, and by covering the inner wall of the concrete foundation with a heat insulating material. At this time, it is necessary to provide a pass-through or inspection opening (foundation inspection opening) for inspecting the underfloor in the continuous foundation.

本出願人は、このような基礎点検口に採用可能な、布基礎に固定される枠体と、断熱性を有する発泡樹脂製の蓋体と、蓋体を枠体に押止するためのロック機構とを有する基礎点検口について提案している（特許文献１参照）。この基礎点検口においては、ロックを解除して蓋体を手前に引くことで、枠体から蓋体が取り外せ、蓋体を枠体に嵌合して再びロックすれば元の状態に戻る。つまり、何度でも簡単に基礎点検口の開閉が可能となり、浴室区画の点検を容易に行うことが可能となる。 The present applicant has proposed a frame fixed to a continuous foundation, a heat-insulating foamed resin lid, and a lock for holding the lid to the frame, which can be adopted for such a foundation inspection opening. proposed a basic inspection door having a mechanism (see Patent Document 1). In this basic inspection opening, the lid can be removed from the frame by releasing the lock and pulling the lid forward, and the original state can be restored by fitting the lid to the frame and locking it again. That is, the opening and closing of the basic inspection door can be easily opened and closed any number of times, and inspection of the bathroom section can be easily performed.

以下、本発明の一実施形態に係る基礎点検口１０が取り付けられた建物構造１００について、図１を参照しつつ以下に説明する。 A building structure 100 having a basic inspection opening 10 according to an embodiment of the present invention will be described below with reference to FIG.

本実施形態における建物構造１００は、図１に示すように、長手方向Ａに長尺な基礎１（例えば、布基礎）と、基礎１に設置された基礎点検口１０と、基礎１上に配置された土台３と、土台３と基礎１との間に配置された基礎パッキン４とを含んでなる。なお、図１に示す建物構造１００は、ユニットバスを用いた浴室の下方空間を画定する基礎構造の一部分を示しており、基礎１の立ち上がり部１ｂの幅方向Ｂ（長手方向Ａと直交する方向）に沿って立ち上がり部１ｂよりも図中左側が内側で右側が外側となっている。これより、以下の説明において、幅方向Ｂの一方を外側、他方を内側と称することがある。また、以下の基礎点検口１０の説明において、便宜上、基礎１に取り付けられた基礎点検口１０を外側から見たときの、幅方向Ｂの一方である外側が前方、他方を後方として説明する。つまり、幅方向Ｂを前後方向Ｂと称し、前後方向Ｂと直交する長手方向Ａを左右方向Ａと称する。また、基礎点検口１０の左右は、基礎点検口１０を前方から見たときの左右である。 The building structure 100 in this embodiment, as shown in FIG. and a foundation packing 4 arranged between the foundation 3 and the foundation 1. In addition, the building structure 100 shown in FIG. 1 shows a part of the foundation structure that defines the lower space of the bathroom using the unit bath, and the width direction B of the rising portion 1b of the foundation 1 (the direction orthogonal to the longitudinal direction A) ), the left side of the rising portion 1b in the figure is the inner side, and the right side is the outer side. Therefore, in the following description, one side of the width direction B may be referred to as the outer side, and the other side as the inner side. In addition, in the following description of the basic inspection opening 10, for convenience, when the basic inspection opening 10 attached to the foundation 1 is viewed from the outside, one side in the width direction B is the front side, and the other side is the rear side. That is, the width direction B is referred to as the front-rear direction B, and the longitudinal direction A perpendicular to the front-rear direction B is referred to as the left-right direction A. The left and right sides of the basic inspection opening 10 are the left and right sides when the basic inspection opening 10 is viewed from the front.

基礎１は、フーチング１ａとフーチング１ａから上方に立設された立ち上がり部１ｂとで構成されている。土台３及び基礎パッキン４は、基礎１に植設されたアンカーボルト、角座金及びナット（ともに図示せず）によって立ち上がり部１ｂ上に固定されている。立ち上がり部１ｂの内側面１ｃ全体には、断熱材６が設けられている。なお、断熱材６は、立ち上がり部１ｂの外側面１ｄに設けられていてもよい。 The base 1 is composed of a footing 1a and a rising portion 1b erected upward from the footing 1a. The base 3 and the base packing 4 are fixed on the raised portion 1b by anchor bolts, square washers and nuts (none of which are shown) implanted in the base 1. As shown in FIG. A heat insulating material 6 is provided on the entire inner surface 1c of the rising portion 1b. Note that the heat insulating material 6 may be provided on the outer side surface 1d of the rising portion 1b.

続いて、基礎点検口１０について、図２～図１０を参照しつつ以下に説明する。基礎点検口１０は、図２に示すように、枠体１１と、蓋体２１とを有する。枠体１１は、図３及び図４に示すように、枠部１２と、枠部１２の内周縁部に設けられた合成樹脂からなる２つの被係止部材１３とを有している。枠部１２は、四角筒状の筒体１２ａと、筒体１２ａの前方に設けられたフランジ１２ｂとを有しており、発泡合成樹脂製（例えば、ＥＰＳ：ビーズ法ポリスチレンフォーム）である。なお、枠部１２は、他の合成樹脂から構成されていてもよい。 Next, the basic inspection opening 10 will be described below with reference to FIGS. 2 to 10. FIG. The basic inspection opening 10 has a frame 11 and a lid 21, as shown in FIG. As shown in FIGS. 3 and 4, the frame 11 has a frame portion 12 and two locked members 13 made of synthetic resin and provided on the inner peripheral edge portion of the frame portion 12 . The frame portion 12 has a square tubular body 12a and a flange 12b provided in front of the tubular body 12a, and is made of foamed synthetic resin (for example, EPS: bead polystyrene foam). Note that the frame portion 12 may be made of another synthetic resin.

筒体１２ａは、開口部１２ａ１を画定しており、その後端部には、開口部１２ａ１の後方を塞ぐように、打ち抜き板１２ｃが肉薄部１２ｄを介して一体的に形成されている。この打ち抜き板１２ｃは、基礎形成後には、肉薄部１２ｄにおいてユーザにより切り離す（打ち抜く）ことができる。打ち抜き板１２ｃが形成されていることで、枠体１１の形状が維持されるため、基礎形成時に流し込まれるコンクリートによって枠体１１の特に後方部分にひずみが生じることを防止することができる。さらに、打ち抜き板１２ｃは、開口部１２ａ１の後方部分を塞いでいるため、基礎形成時のコンクリートが枠体１１内に流れ込むのを防止することができる。また、打ち抜き板１２ｃは、肉薄部１２ｄを介して枠体１１と繋がっているため、基礎完成後に容易に打ち抜くことができる。 The cylindrical body 12a defines an opening 12a1, and a punched plate 12c is integrally formed at the rear end thereof via a thin portion 12d so as to close the rear of the opening 12a1. This punching plate 12c can be separated (punched) by the user at the thin portion 12d after the foundation is formed. Since the shape of the frame 11 is maintained by forming the punched plate 12c, it is possible to prevent the frame 11 from being distorted, especially in the rear portion thereof, due to the concrete that is poured during foundation formation. Furthermore, since the punched plate 12c closes the rear portion of the opening 12a1, it is possible to prevent concrete from flowing into the frame 11 during foundation formation. Further, since the punched plate 12c is connected to the frame body 11 through the thin portion 12d, it can be easily punched out after the foundation is completed.

図２（ｂ）及び図３に示すように、枠部１２の左右側面の下部には、仮止釘用リブ１１ｂがそれぞれ設けられている。これら仮止釘用リブ１１ｂを介して基礎形成下地面に釘を打ち込むことにより、基礎点検口１を布基礎形成下地面に固定（仮止め）することができる。 As shown in FIGS. 2(b) and 3, ribs 11b for temporary nailing are provided at lower portions of the left and right side surfaces of the frame portion 12, respectively. The foundation inspection opening 1 can be fixed (temporarily fixed) to the continuous foundation formation surface by driving nails into the foundation formation surface through these temporary nail ribs 11b.

フランジ１２ｂは、図４に示すように、開口部１２ａ１よりも一回り大きな開口部１２ｂ１を画定している。筒体１２ａの開口部１２ａ１とフランジ１２ｂの開口部１２ｂ１とが接続面１２ａｂで接続され、枠体１１の開口部１１ａを構成している。 As shown in FIG. 4, the flange 12b defines an opening 12b1 that is slightly larger than the opening 12a1. An opening 12a1 of the cylindrical body 12a and an opening 12b1 of the flange 12b are connected by a connecting surface 12ab to form an opening 11a of the frame 11. As shown in FIG.

フランジ１２ｂの鉛直方向Ｃに沿って平行な左右の垂直部１２ｂａのそれぞれには、図５に示すように、被係止部材１３を固定するための２つの貫通孔１２ｂ２が形成されている。これら貫通孔１２ｂ２は、前後方向Ｂに貫通しており、図５（ａ）に示すように前方開口部分は四角形状を有し、図５（ｂ）に示すように後方開口部分は円形状を有している。また、各垂直部１２ｂａには、２つの溝部１２ｂ３と２つの凹部１２ｂ４とが形成されている。２つの溝部１２ｂ３は、図５（ａ）に示すように、フランジ１２ｂの内周面において、鉛直方向Ｃに互いに離隔して配置され、前後方向Ｂの中央部分から前方に向かって延在して形成されている。２つの凹部１２ｂ４は、前方及び開口部１２ｂ１側（すなわち、内側）に向かって開口しており、２つの貫通孔１２ｂ２及び２つの溝部１２ｂ３を鉛直方向Ｃに挟む位置に配置されている。また、左右の垂直部１２ｂａに形成された２つの貫通孔１２ｂ２、２つの溝部１２ｂ３及び２つの凹部１２ｂ４は、枠部１２の左右方向Ａの中心を通る鉛直方向Ｃの中心線に対して線対称に配置されている。 As shown in FIG. 5, two through holes 12b2 for fixing the engaged member 13 are formed in each of the left and right vertical portions 12ba parallel to the vertical direction C of the flange 12b.

Note that the lid portion 22 may be made of another synthetic resin as long as it has a heat insulating property. Two concave portions 22a1 and 22a2 are formed in the front surface 22a of the lid portion 22. As shown in FIG. The concave portion 22a2 is arranged slightly to the left of the center of the lid portion 22 in the left-right direction A, and has an elongated hole shape elongated in the vertical direction C. As shown in FIG.

凹部２２ａ１は、図８に示すように、蓋部２２の左側端部に配置されている。また、凹部２２ａ１は、蓋部２２の前面２２ａから左側面２２ｃを経由して後面２２ｂにかけて形成されており、係止部材２３を取り付けるための部分である。凹部２２ａ１の前面２２ａ側の部分には、図９（ａ）に示すように、穴部２４と、溝部２５とが形成されている。穴部２４は、左右方向Ａにやや長尺な長穴形状となっている。溝部２５は、鉛直方向Ｃに長尺に延在している。凹部２２ａ１の後面２２ｂ側の部分には、図９（ｂ）に示すように、鉛直方向Ｃに長尺に延在する溝部２６が形成されている。 The recessed portion 22a1 is arranged at the left end portion of the lid portion 22, as shown in FIG. Further, the recessed portion 22a1 is formed from the front surface 22a of the lid portion 22 to the rear surface 22b via the left side surface 22c, and is a portion for attaching the locking member 23. As shown in FIG. As shown in FIG. 9A, a hole 24 and a groove 25 are formed in the recess 22a1 on the front surface 22a side. The hole portion 24 has an elongated hole shape that is slightly elongated in the left-right direction A. As shown in FIG. The groove portion 25 extends long in the vertical direction C. As shown in FIG. A groove portion 26 elongated in the vertical direction C is formed in the rear surface 22b side portion of the recess portion 22a1, as shown in FIG. 9B.

蓋部２２の右側面２２ｄには、図８（ａ）に示すように、右側に突出する２つの突起２７が形成されている。これら突起２７は、鉛直方向Ｃに互いに離隔して配置されている。各突起２７は、蓋体２１を枠体１１の開口部１１ａに嵌合したときに、上述したガイド片１４の水平部１４ｂ、ガイド片１５，１６及び凹部１２ｂ４によって画定された挿入部１１ｄのそれぞれにちょうど挿入可能な大きさに形成されている。 As shown in FIG. 8A, two protrusions 27 are formed on the right side surface 22d of the lid portion 22 so as to protrude to the right. These protrusions 27 are arranged apart from each other in the vertical direction C. As shown in FIG. Each protrusion 27 is formed in an insertion portion 11d defined by the horizontal portion 14b of the guide piece 14, the guide pieces 15 and 16, and the concave portion 12b4 when the lid 21 is fitted into the opening 11a of the frame 11. It is formed in a size that can be inserted just into the

蓋部２２の後面２２ｂには、図８（ｂ）に示すように、３つの突起２２ｂ１が形成されている。これら突起２２ｂ１は、左右方向Ａに長尺に形成されており、鉛直方向Ｃに互いに離隔して配置されている。また、蓋部２２の後方部分には、段差部３０が周縁部全体に形成されている。この段差部３０によって形成された垂直な段差面３１は、蓋体２１が枠体１１に取り付けられたときに、枠体１１の開口部１１ａの接続面１２ａｂと当接する面である。つまり、蓋体２１が枠体１１に取り付けられることで、段差面３１と接続面１２ａｂとが当接し、枠体１１の開口部１１ａが蓋体２１によって封止される。 Three projections 22b1 are formed on the rear surface 22b of the lid portion 22, as shown in FIG. 8(b). These projections 22b1 are elongated in the left-right direction A and arranged apart from each other in the vertical direction C. As shown in FIG. A stepped portion 30 is formed along the entire peripheral portion of the rear portion of the lid portion 22 . A vertical stepped surface 31 formed by the stepped portion 30 is a surface that contacts the connection surface 12ab of the opening 11a of the frame 11 when the lid 21 is attached to the frame 11 . That is, when the lid 21 is attached to the frame 11 , the stepped surface 31 and the connection surface 12 ab are brought into contact with each other, and the opening 11 a of the frame 11 is sealed by the lid 21 .

係止部材２３は、図１０に示すように、蓋部２２の端部を挟持する挟持部４１と、挟持部４１に一体的に形成された操作部４２とを有する。挟持部４１は、前方部５１と、側方部５２と、後方部５３とを有しており、これら各部５１～５３が連続して略コの字形状を構成する板状部材からなる。前方部５１は、図１０（ｃ）に示すように、前方から見て、鉛直方向Ｃに長尺な長方形平面形状を有している。前方部５１の右端部には、図１０（ｂ）及び図１０（ｃ）に示すように、後方に突出する突起５１ａが形成されている。突起５１ａは、溝部２５にちょうど嵌合可能な形状に形成されている。 The locking member 23 has, as shown in FIG. 10 , a clamping portion 41 that clamps the end portion of the lid portion 22 and an operating portion 42 integrally formed with the clamping portion 41 . The clamping portion 41 has a front portion 51, a side portion 52, and a rear portion 53, and these portions 51 to 53 are formed of a plate-like member that continuously forms a substantially U-shape. As shown in FIG. 10(c), the front portion 51 has a rectangular planar shape elongated in the vertical direction C when viewed from the front. As shown in FIGS. 10(b) and 10(c), the right end of the front portion 51 is formed with a projection 51a projecting rearward. The projection 51 a is formed in a shape that can be just fitted into the groove portion 25 .

側方部５２は、図１０（ｂ）に示すように、蓋部２２の段差部３０の形状に沿って屈曲しており、その前方が前方部５１と一体的に接続されている。後方部５３は、後方から見て、鉛直方向Ｃに長尺な長方形形状を有しており、側方部５２の後端と一体的に接続されている。後方部５３の先端（右端部）には、前方に突出する突起５３ａが形成されている。突起５３ａは、溝部２６にちょうど嵌合可能な形状に形成されている。 As shown in FIG. 10(b), the side portion 52 is bent along the shape of the stepped portion 30 of the lid portion 22, and the front portion thereof is integrally connected to the front portion 51. As shown in FIG. The rear portion 53 has a rectangular shape elongated in the vertical direction C when viewed from the rear, and is integrally connected to the rear ends of the side portions 52 . A projection 53a projecting forward is formed at the tip (right end) of the rear portion 53 . The projection 53a is formed in a shape that can be just fitted into the groove portion 26. As shown in FIG.

操作部４２は、前方から見て略半円形状の第１部分４３と、側方部５２を鉛直方向Ｃに挟む位置に配置され第１部分４３と側方部５２の後方部分とを接続する一対の第２部分４４とを有している。第１部分４３は、前後方向Ｂに貫通する円孔４３ａが形成された板状部材からなる。第２部分４４は、第１部分４３の左側端部から左方に延在してから後方に折れ曲がって段差部３０の形状に沿って屈曲する板状部材からなる。また、一対の第２部分４４には、係止突起４６が形成されている。係止突起４６は、後方に向かうに連れて第２部分４４から離れるように傾斜する前方傾斜部４６ａと、前方に向かうに連れて第２部分４４から離れるに傾斜する後方傾斜部４６ｂとを有している。 The operation part 42 is arranged at a position sandwiching the side part 52 in the vertical direction C, and connecting the first part 43 and the rear part of the side part 52 to each other. and a pair of second portions 44 . The first portion 43 is made of a plate-like member having a circular hole 43a extending therethrough in the front-rear direction B. As shown in FIG. The second portion 44 is a plate-like member that extends leftward from the left end portion of the first portion 43 and then bends rearward to follow the shape of the stepped portion 30 . Further, locking protrusions 46 are formed on the pair of second portions 44 . The locking protrusion 46 has a forward inclined portion 46a that is inclined away from the second portion 44 as it goes rearward, and a rearward inclined portion 46b that is inclined away from the second portion 44 as it goes forward. is doing.

このような係止部材２３は、突起５１ａが溝部２５に、突起５３ａが溝部２６に嵌合するようにして凹部２２ａ１に取り付けられる。これにより、係止部材２３は、図８に示すように、挟持部４１によって、蓋部２２の左側端部を前後方向Ｂに挟持するようにして取り付けられる。操作部４２は、図１０に示すように、側方部５２との接続箇所以外は挟持部４１からスリット４５を介して離隔している。これにより、蓋部２２に取り付けられた係止部材２３の操作部４２の第１部分４３は、第２部分４４の弾性変形によって左右方向Ａに移動可能となる。このため、ユーザが第１部分４３の円孔４３ａ及び凹部２２ａ２に指を入れて、第１部分４３を凹部２２ａ２に近づく方向に移動させると、第２部分４４が弾性変形して第１部分４３が凹部２２ａ２に近付く。つまり、第１部分４３が右方に移動する。このとき、第２部分４４の前方部分も右方に移動するため、溝部１１ｃ内に挿入され被係止部材１３と係止する係止突起４６が溝部１１ｃから脱して、その係止が解除される。こうして、係止突起４６と被係止部材１３との係止が解除されているときに、蓋体２１を枠体１１から前方に取り外すことが可能となる。一方、枠体１１の開口部１１ａに蓋体２１を取り付ける際は、２つの突起２７を左右いずれか一方にある２つの挿入部１１ｄに挿入する。そして、蓋体２１を開口部１１ａ内に押し込むと、係止突起４６の後方傾斜部４６ｂと他方にある被係止部材１３とが係合して操作部４２が左右方向Ａに移動し、係止突起４６が溝部１１ｃ内に挿入され被係止部材１３と係止される。こうして、蓋体２１が枠体１１にロックされた状態で取り付けられる。 Such a locking member 23 is attached to the concave portion 22a1 so that the projection 51a fits into the groove portion 25 and the projection 53a fits into the groove portion 26. As shown in FIG. 8, the locking member 23 is attached so that the left end portion of the lid portion 22 is sandwiched in the front-rear direction B by the sandwiching portion 41. As shown in FIG. As shown in FIG. 10 , the operating portion 42 is separated from the clamping portion 41 via the slit 45 except for the connecting portion with the side portion 52 . As a result, the first portion 43 of the operation portion 42 of the locking member 23 attached to the lid portion 22 can move in the left-right direction A due to the elastic deformation of the second portion 44 . Therefore, when the user puts a finger in the circular hole 43a and the recess 22a2 of the first portion 43 and moves the first portion 43 in a direction approaching the recess 22a2, the second portion 44 is elastically deformed and the first portion 43 approaches the recess 22a2. That is, the first portion 43 moves rightward. At this time, since the front portion of the second portion 44 also moves to the right, the locking projection 46 inserted into the groove 11c and locked to the locked member 13 is removed from the groove 11c, and the locking is released. be. In this way, the lid 21 can be removed forward from the frame 11 when the locking between the locking projection 46 and the locked member 13 is released. On the other hand, when attaching the lid 21 to the opening 11a of the frame 11, the two protrusions 27 are inserted into the two insertion portions 11d on either the left or right side. When the lid body 21 is pushed into the opening 11a, the rear inclined portion 46b of the locking projection 46 and the locked member 13 on the other side are engaged with each other to move the operation portion 42 in the left-right direction A, thereby locking. The locking projection 46 is inserted into the groove portion 11c and locked with the locked member 13. As shown in FIG. Thus, the lid 21 is attached to the frame 11 in a locked state.

このような係止部材２３が蓋体２１に設けられていることで、蓋部２２を開口部１１ａに嵌合させるだけで、蓋体２１を枠体１１に容易に係止、すなわちロックすることが可能となる。また、係止部材２３が、複数の別部材の組み合わせで構成されているものよりも製造コストが小さくなる。 Since the locking member 23 is provided on the lid 21, the lid 21 can be easily locked to the frame 11 simply by fitting the lid 22 into the opening 11a. becomes possible. Moreover, the manufacturing cost is lower than when the locking member 23 is configured by combining a plurality of separate members.

なお、本実施形態における枠体１１は、左右方向Ａの中心を通る鉛直方向Ｃに平行な中心線に対して線対称に形成されている。このため、蓋体２１は、係止部材２３が左右のどちらにあるように配置されても、枠体１１に取り付けることができる。 In addition, the frame 11 in this embodiment is formed line-symmetrically with respect to a center line passing through the center in the left-right direction A and parallel to the vertical direction C. As shown in FIG. Therefore, the lid body 21 can be attached to the frame body 11 regardless of whether the locking member 23 is arranged on the left or the right side.

以上に述べたように、本実施形態の基礎点検口１０によると、係止部材２３が前後方向Ｂから挟持するようにして蓋部２２に取り付けられているので、蓋部２２が比較的脆い材料（発泡樹脂）から構成されていても、係止部材２３が蓋部２２から脱落するのを軽減することが可能となる。 As described above, according to the basic inspection opening 10 of the present embodiment, since the locking member 23 is attached to the lid portion 22 so as to be sandwiched from the front-rear direction B, the lid portion 22 is made of a relatively fragile material. (foamed resin), it is possible to reduce the possibility that the locking member 23 falls off from the lid portion 22 .

また、被係止部材１３が枠部１２を前後方向Ｂから挟持するようにして取り付けられている。これにより、枠部１２が比較的脆い材料（発泡樹脂）から構成されていても、被係止部材１３が枠部１２から脱落するのを軽減することが可能となる。 Further, the locked member 13 is attached so as to sandwich the frame portion 12 from the front-rear direction B. As shown in FIG. As a result, even if the frame portion 12 is made of a relatively fragile material (foamed resin), it is possible to reduce the likelihood that the locked member 13 will drop out of the frame portion 12 .

また、挟持部４１の前方部５１に突起５１ａが形成され、後方部５３に突起５３ａが形成されていることで、挟持部４１が蓋部２２に対して左右方向Ａへの移動が規制される。これにより、操作部４２が左右方向Ａに移動する際に、挟持部４１が左右方向Ａに移動しにくくなる。このため、蓋体２１を枠体１１に効果的にロックすることが可能となる。 Further, since the projection 51a is formed on the front portion 51 of the holding portion 41 and the projection 53a is formed on the rear portion 53, the movement of the holding portion 41 in the left-right direction A with respect to the lid portion 22 is restricted. . Thereby, when the operation part 42 moves in the left-right direction A, the holding part 41 becomes difficult to move in the left-right direction A. Therefore, it is possible to effectively lock the lid 21 to the frame 11 .

以上、本発明の好適な実施の形態について説明したが、本発明は上述の実施の形態に限られるものではなく、特許請求の範囲に記載した限りにおいて様々な変更が可能なものである。例えば、上述の実施形態においては、係止部材２３が蓋部２２の左右方向Ａの一方に配置されているが、鉛直方向Ｃの一方に配置されていてもよい。この場合、被係止部（被係止部材）も、係止部材に対応するように、枠部１２の鉛直方向Ｃの一方に配置されておればよい。これにおいても、上述と同様の効果を得ることができる。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, in the above-described embodiment, the locking member 23 is arranged on one side of the lid portion 22 in the left-right direction A, but it may be arranged on one side in the vertical direction C. In this case, the to-be-latched portion (to-be-latched member) may also be arranged on one side of the frame portion 12 in the vertical direction C so as to correspond to the engaging member. Also in this case, the same effect as described above can be obtained.

また、上述の実施形態における被係止部材１３は、枠部１２を前後方向Ｂから挟持するようにして取り付けられているが、枠部１２と一体的に形成されていてもよい。この場合、係止部材２３の係止突起４６と係止可能な溝又は凹部（被係止部）が枠部の内周縁部に設けられておればよい。 Moreover, although the locked member 13 in the above-described embodiment is attached so as to sandwich the frame portion 12 from the front-rear direction B, it may be formed integrally with the frame portion 12 . In this case, a groove or a recess (locked portion) that can be locked with the locking protrusion 46 of the locking member 23 may be provided in the inner peripheral edge portion of the frame portion.

また、係止部材２３に形成された突起５１ａ及び突起５３ａは、いずれか一方だけが形成されていてもよいし、両方とも形成されていなくてもよい。 Either one of the protrusions 51a and the protrusions 53a formed on the locking member 23 may be formed, or both of them may not be formed.

また、上述の実施形態においては、第１部分４３（操作部４２）を右方に移動することで係止が解除されるようにしているが、係止部材を、単に前方部、後方部、及び、前記前方部と前記後方部とを繋ぐ側方部からなる略コ字状とし、この係止部材を蓋部の外周端部を挟持するように取り付け、枠体に蓋体を嵌め込み係止部材を被係止部材に係止した状態で、前方部を弾性変形により前方乃至右方に移動（変形）させることで、被係止部に対する係止部材の係止を解除できるように、係止部材が構成されていてもよい。 In the above-described embodiment, the locking is released by moving the first portion 43 (operation portion 42) to the right. and a substantially U-shaped side portion connecting the front portion and the rear portion. By moving (deforming) the front portion forward or rightward due to elastic deformation in a state in which the member is locked to the member to be locked, the locking of the locking member to the locked portion can be released. A stop member may be configured.
