しかしながら、近年は窓の各フレームを見え難くしてスリムに見せたいという要望が強いため、下側の横框を下枠に埋没させたり横框の見付け幅を小さくする傾向にある。そのようになると、横框に対して補助錠を設けるスペースが無くなる等の理由から、補助錠を横框に設けることが困難になる。このため、ストッパが上方に突出するように補助錠を下枠に設けることが考えられるが、ストッパは解錠時にはケースに収容され、施錠時に下枠より上方に突出するため、施錠時にストッパが収容されていた部位と突出したストッパとの間に空隙が形成される。このとき補助錠が下枠に設けられていると、収容されていた部位と突出したストッパとの間の空隙に小さなゴミや埃等が入り込み補助錠を収容できなくなる虞があるという課題があった。 However, in recent years, there is a strong demand to make each frame of the window difficult to see and to make it look slim, and therefore, there is a tendency to bury the lower buoy in the lower frame or to reduce the width of the buoy. In such a case, it becomes difficult to provide the auxiliary lock on the reed because the space for providing the auxiliary lock on the recumbent is eliminated. For this reason, it is conceivable that an auxiliary lock is provided on the lower frame so that the stopper protrudes upward. However, the stopper is accommodated in the case when unlocked and protrudes upward from the lower frame when locked, so that the stopper is accommodated when locking. A gap is formed between the formed portion and the protruding stopper. At this time, if the auxiliary lock is provided on the lower frame, there is a problem that there is a possibility that small dust or dust may enter the gap between the housed portion and the protruding stopper and the auxiliary lock cannot be accommodated. .

本発明は、かかる課題に鑑みてなされたものであり、その目的とするところは、下枠に設けられてもゴミや埃等により機能が阻害され難い補助錠を備えた建具を提供することにある。 The present invention has been made in view of such a problem, and an object of the present invention is to provide a joinery including an auxiliary lock whose function is hardly hindered by dust, dust, or the like even when provided on a lower frame. is there.

かかる目的を達成するために本発明の建具は、室内外を連通する開口に設けられる枠体と、前記枠体に沿って移動可能に設けられ前記開口を閉塞可能な障子と、前記枠体に設けられ前記障子の移動を規制するための補助錠と、を有し、前記補助錠は、上方に突出することにより、前記枠体が有する下枠における前記障子の移動領域に突出して前記障子の移動を規制する規制部と、当該補助錠の解錠時に前記規制部が収容され前記移動領域より下方に窪ませて形成された収容部と、当該補助錠の施錠時に上方に突出された前記規制部と前記収容部との間を閉塞するための閉塞部と、を有し、前記閉塞部は、前記補助錠の解錠時に先端側が下方に向かう傾斜面をなし、前記収容部には、前記傾斜面の下端側の部位に前記収容部外に連通する連通孔を有することを特徴とする建具である。 In order to achieve such an object, the joinery of the present invention includes a frame body provided in an opening that communicates indoors and outdoors, a shoji that is provided movably along the frame body, and that can close the opening, and the frame body. An auxiliary lock for restricting movement of the shoji, and the auxiliary lock protrudes upward to project into the moving area of the shoji in the lower frame of the frame. A restricting part for restricting movement; an accommodating part that is accommodated when the restricting part is unlocked and recessed below the moving region; and the restricting part that protrudes upward when the auxiliary lock is locked A closing portion for closing between the portion and the storage portion, the closing portion has an inclined surface whose front end side is directed downward when the auxiliary lock is unlocked. A communication hole that communicates with the outside of the housing portion at the lower end portion of the inclined surface A joinery, characterized in that it comprises.

このような建具によれば、補助錠には規制部と収容部との間を閉塞するための閉塞部が設けられているので、施錠時に規制部が収容部から突出しても、突出された前記規制部と前記収容部との間は閉塞されている。このため、補助錠が下枠に設けられていても、収容部内にゴミや埃等が入り込み難いので、解錠時に収容される規制部の妨げになることはなく、ゴミや埃等により機能が阻害され難い補助錠を備えた建具を提供することが可能である。
また、補助錠の解錠時には、閉塞部は先端が下方に向かう傾斜面をなすように構成されているので、たとえ施錠時に閉塞部上にゴミや埃が溜まったとしても、解錠することにより溜まったゴミ等は傾斜面を滑り落ちるため、閉塞部上からゴミや埃を除去することが可能である。また、収容部には、傾斜面の下端側の部位に収容部外に連通する連通孔が設けられているので、閉塞部上に溜まったゴミや埃等を収容部外に排出して収容部から除去することが可能である。 According to such a joinery, since the auxiliary lock is provided with the closing portion for closing the space between the restricting portion and the accommodating portion, the protruding portion is protruded even if the restricting portion protrudes from the accommodating portion at the time of locking. The space between the restricting portion and the accommodating portion is closed. For this reason, even if the auxiliary lock is provided on the lower frame, it is difficult for dust, dust, etc. to enter the accommodating portion, so that it does not interfere with the restricting portion accommodated during unlocking, and functions due to dust, dust, etc. It is possible to provide a fitting with an auxiliary lock that is not easily disturbed.
In addition, when the auxiliary lock is unlocked, the closing portion is configured so that the tip has an inclined surface directed downward, so even if dust or dirt accumulates on the closing portion during locking, Since accumulated dust or the like slides down the inclined surface, it is possible to remove dust and dust from the closed portion. In addition, since the accommodation portion is provided with a communication hole that communicates with the outside of the accommodation portion at the lower end side of the inclined surface, dust and dust accumulated on the closed portion are discharged out of the accommodation portion. Can be removed.

かかる建具であって、前記閉塞部は、前記規制部が見込み方向に沿う軸を中心として回動することにより前記移動領域に突出した際に、平坦な面を形成して前記収容部と前記規制部との間を閉塞することが望ましい。
このような建具によれば、規制部が移動領域に突出した際には、閉塞部が収容部と規制部との間を閉塞して平坦な面を形成し、収容部と規制部との間に窪みが形成されないので、閉塞部の上方にゴミや埃等が溜まりにくい建具を提供することが可能である。 In this joinery, the closing part forms a flat surface when the restricting part protrudes into the moving region by rotating about the axis along the prospective direction, and forms the flat part and the accommodating part and the restricting part. It is desirable to block between the parts.
According to such a joinery, when the restricting portion protrudes into the moving region, the closing portion closes between the accommodating portion and the restricting portion to form a flat surface, and between the accommodating portion and the restricting portion. Therefore, it is possible to provide a joinery in which dust, dust, and the like are not easily accumulated above the closed portion.

かかる建具であって、前記閉塞部は、平坦な面を形成し、前記規制部側に付勢されて当該規制部に当接されつつ前記障子の移動方向に沿ってスライド自在に設けられ、前記規制部が、見込み方向に沿う軸を中心に回動することにより前記移動領域に突出した際に、前記規制部に当接された状態を維持しつつスライドすることとしてもよい。
このような建具によれば、閉塞部は規制部側に付勢されて当該規制部に当接されつつ障子の移動方向に沿ってスライド自在に設けられているので、規制部の変位に追従してスライドし、規制部が移動領域内に突出する際にも常に収容部と規制部との間を閉塞することが可能である。このため、規制部と収容部との間にゴミや埃が入り込むことを防止することが可能である。 In this fitting, the blocking portion forms a flat surface, is slid along the moving direction of the shoji while being urged toward the regulating portion and abutting on the regulating portion, The restricting portion may slide while maintaining the state in contact with the restricting portion when the restricting portion protrudes into the moving region by rotating about an axis along the prospective direction.
According to such a fitting, the blocking portion is slid along the moving direction of the shoji while being urged toward the regulating portion and being in contact with the regulating portion, and therefore follows the displacement of the regulating portion. It is possible to always close the space between the accommodating portion and the restricting portion even when the restricting portion protrudes into the movement region. For this reason, it is possible to prevent dust and dirt from entering between the restricting portion and the accommodating portion.

本発明によれば、下枠に設けられてもゴミや埃ゴミや埃等により機能が阻害され難い補助錠を備えた建具を提供することが可能である。 ADVANTAGE OF THE INVENTION According to this invention, even if it is provided in a lower frame, it is possible to provide the joinery provided with the auxiliary | assistant lock | rock whose function is hard to be inhibited by dust, dust, and dust.

底部２６の下面２６ａには、収容凹部１６を構成するレール載置部１２ｂに設けられた取付孔９に係止される鉤部２８が、見付け方向に並べて２カ所設けられている。鉤部２８は、取付孔９と相似形状をなし、取付孔９の外形形状より僅かに小さな外形形状をなす鉤体部２８ａと、鉤体部２８ａと底部２６とを連結する連結部２８ｄとを有している。 On the lower surface 26 a of the bottom portion 26, two hook portions 28 are provided side by side in the direction of finding, and are engaged with the mounting holes 9 provided in the rail mounting portion 12 b constituting the housing recess 16. The flange portion 28 has a similar shape to the mounting hole 9, and includes a housing portion 28 a having an outer shape slightly smaller than the outer shape of the mounting hole 9, and a connecting portion 28 d that connects the housing portion 28 a and the bottom portion 26. Have.

鉤体部２８ａは、取付孔９と相似形状をなしているので、取付孔９と同様に、図７に示すように、可動障子側の円形部分２８ｂと、円形部分２８ｂと繋がった枠体側の長丸部分２８ｃとにて形成されている。鉤体部２８ａの上面と底部２６の下面２６ａとの間隔はレール載置部１２ｂの肉厚より僅かに広く形成されている。連結部２８ｄは、長丸部分２８ｃの見込み方向の幅とほぼ同じ幅を有しており、円形部分２８ｂの上面に設けられている。 Since the housing portion 28a has a similar shape to the attachment hole 9, as shown in FIG. 7, the circular portion 28b on the movable shoji side and the frame side connected to the circular portion 28b are provided as in the attachment hole 9. It is formed with the long round part 28c. The distance between the upper surface of the housing portion 28a and the lower surface 26a of the bottom portion 26 is slightly wider than the thickness of the rail mounting portion 12b. The connecting portion 28d has substantially the same width as the prospective direction of the oval portion 28c, and is provided on the upper surface of the circular portion 28b.

底部２６には、２カ所の鉤部２８の間に、底部２６のほぼ平坦な内面２６ｃより僅かに突出する爪部２６ｄが設けられており、爪部２６ｄと、この爪部２６ｄを上下方向に変位可能とするために片持ち支持して弾性変形するように設けられた腕部２６ｅとが、腕部２６ｅの支持部２６ｆを除いた輪郭に沿って底部２６から切り離されている。ここで、爪部２６ｄの頂点の位置は、室内側ケース部２２及び室外側ケース部２３に設けられた軸受部２７と見付け方向においてほぼ同じ位置に配置されている。 The bottom portion 26 is provided with a claw portion 26d that slightly protrudes from the substantially flat inner surface 26c of the bottom portion 26 between the two flange portions 28.

錠本体３０は、ケーシング２１の軸受部２７に支持されて回動自在に収容され、一体に形成されたブロック状の部材である。錠本体３０は、解錠状態にてケーシング２１に収容された際に上方に露出する平坦な面でなる上面部３１と、室内側の面３２から室内側に、室外側の面３３から室外側にそれぞれ突出され、軸受部２７に支持される軸突部３７と、下面３４に設けられ下方に突出されて爪部２６ｄと係合する突起３４ａと、可動障子側に設けられ、施錠状態にて可動障子５が移動された際に可動障子５の移動を規制する規制部３５と、規制部３５と直交する面を形成し施錠状態にて可動障子側ケース部２４の上端と規制部３５との間を閉塞する閉塞部３６と、を有している。ここで、施錠時にケーシング２１より上方に突出する部位が規制部３５であり、施錠時にケーシング２１と規制部３５との間を閉塞する部位が閉塞部３６である。 The lock body 30 is a block-shaped member that is supported by the bearing portion 27 of the casing 21 and is rotatably accommodated and integrally formed. The lock body 30 has an upper surface portion 31 that is a flat surface exposed upward when accommodated in the casing 21 in an unlocked state, the indoor surface 32 to the indoor side, and the outdoor surface 33 to the outdoor surface. The shaft projection 37 is supported by the bearing 27, the projection 34a is provided on the lower surface 34 and is projected downward to engage with the claw portion 26d. A restriction part 35 that restricts movement of the movable obstacle 5 when the movable obstacle 5 is moved, and a surface orthogonal to the restriction part 35 is formed, and the upper end of the movable obstacle side case part 24 and the restriction part 35 are locked. And a closing portion 36 that closes the gap. Here, a portion that protrudes upward from the casing 21 during locking is the restricting portion 35, and a portion that closes the space between the casing 21 and the restricting portion 35 during locking is the closing portion 36.

補助錠２０は、解錠状態から施錠する際に、錠本体３０の上面部３１における軸突部３７より枠体側の部位が下方に押圧される。このため、錠本体３０は、軸突部３７より枠体側の部位のほうが、可動障子側の部位より見込み方向の幅が広く形成されており、操作しやすく構成されている。 When the auxiliary lock 20 is locked from the unlocked state, the frame side portion of the upper surface portion 31 of the lock body 30 is pressed downward from the shaft projection 37. For this reason, the lock body 30 is formed so that the frame-side portion of the lock body 30 is wider in the prospective direction than the movable shoji-side portion, and is easy to operate.

規制部３５は、施錠時にはケーシング２１より上方に突出して可動障子５の軌道領域にて、可動障子５の召合せ框５ａと対向するようにほぼ鉛直な平面をなす規制面３５ａを有し、閉塞部３６は、規制面３５ａと直交するように設けられ施錠時にケーシング２１の上端とほぼ同じ水平面をなす閉塞面３６ａを有している。また、解錠時には、上面部３１が水平面をなすように錠本体３０がケーシング２１内に収容されるので、施錠時に水平をなしていた閉塞部３６の閉塞面３６ａは、枠体側から可動障子側に向かって順次低くなるように傾斜した傾斜面を形成している。 The restricting portion 35 has a restricting surface 35a that protrudes upward from the casing 21 at the time of locking and forms a substantially vertical plane so as to face the summing rod 5a of the movable obstacle 5 in the track region of the movable obstacle 5. The part 36 has a closing surface 36a which is provided so as to be orthogonal to the regulating surface 35a and forms a horizontal plane substantially the same as the upper end of the casing 21 when locked. Further, since the lock main body 30 is accommodated in the casing 21 so that the upper surface portion 31 forms a horizontal plane at the time of unlocking, the closing surface 36a of the closing portion 36 that has been horizontal at the time of locking is from the frame body side to the movable obstacle side. An inclined surface is formed so as to be gradually lowered toward the surface.

また、錠本体３０がケーシング２１内にて回動する際にケース側曲面２５ｃと対向する枠体側の面３８は、ケース側曲面２５ｃより僅かに小さな半径をなす曲面に形成されている。 Further, when the lock body 30 rotates in the casing 21, the frame-side surface 38 that faces the case-side curved surface 25c is formed as a curved surface having a slightly smaller radius than the case-side curved surface 25c.

このような補助錠２０は、ケーシング２１に錠本体３０が取り付けられた状態にて、収容凹部１６内のレール載置部１２ｂに取り付けられる。補助錠２０を取り付ける際には、まず、補助錠２０に設けられている鉤部２８をレール載置部１２ｂに設けられた取付孔９に上方から挿入し、底部２６がレール載置部１２ｂに当接した後に補助錠２０を可動障子側から枠体側に移動させることにより、取付孔９の長孔部分９ｂに鉤部２８の連結部２８ｄが位置するように配置する。その後、レール部材６０を収容凹部１６に嵌合する。このとき、レール部材６０の切欠部６３ｂの縁が、可動障子側ケース部２４及び枠体側ケース部２５の延出部２４ｂ、２５ｂの上方に位置するため、補助錠２０の見付け方向の移動が規制される。このように取り付けることにより、ビス等を用いることなく補助錠２０を取り付けることが可能である。また、取り付ける際に補助錠２０をスライドさせる方向は、閉じられた可動障子５を開放するために移動させる方向なので、補助錠２０の施錠状態にて可動障子５が移動されて規制部３５に衝突しても、補助錠２０は外れ難いように構成されている。 Such an auxiliary lock 20 is attached to the rail mounting portion 12 b in the housing recess 16 in a state where the lock body 30 is attached to the casing 21. When attaching the auxiliary lock 20, first, the collar portion 28 provided in the auxiliary lock 20 is inserted into the attachment hole 9 provided in the rail mounting portion 12 b from above, and the bottom portion 26 is inserted in the rail mounting portion 12 b. After the contact, the auxiliary lock 20 is moved from the movable shodder side to the frame body side so that the connecting portion 28d of the flange portion 28 is positioned in the long hole portion 9b of the mounting hole 9. Thereafter, the rail member 60 is fitted into the housing recess 16. At this time, since the edge of the notch portion 63b of the rail member 60 is located above the extended portions 24b and 25b of the movable shoji case 24 and the frame case 25, the movement of the auxiliary lock 20 in the direction of finding is restricted. Is done. By attaching in this way, it is possible to attach the auxiliary lock 20 without using screws or the like. Further, since the direction in which the auxiliary lock 20 is slid when attaching is the direction in which the closed movable shoddle 5 is moved, the movable shoddle 5 is moved in the locked state of the auxiliary lock 20 and collides with the restricting portion 35. Even so, the auxiliary lock 20 is configured so as not to easily come off.

補助錠２０は、軸突部３７が見付け方向において錠本体３０の中央より枠体側に偏らせて配置されており、ケーシング２１の軸受部２７に支持された解錠状態では、錠本体３０の軸突部３７より可動障子側の部位の自重により、可動障子側の部位の下面がケーシング２１の底部２６に当接されている。このとき、錠本体３０の上面部３１は、ケーシング２１の室内側ケース部２２、室外側ケース部２３、可動障子側ケース部２４、枠体側ケース部２５の上縁部とほぼ同じ高さの水平面をなしている。また、錠本体３０の下方には、錠本体３０が回動できるように、ケーシング２１との間に空隙が設けられ、下面３４の突起３４ａは、底部２６に設けられた爪部２６ｄの頂部より枠体側にて、爪部２６ｄに当接されている。 The auxiliary lock 20 is arranged such that the shaft protrusion 37 is offset from the center of the lock body 30 toward the frame in the direction of finding, and in the unlocked state supported by the bearing portion 27 of the casing 21, The lower surface of the movable obstacle side is in contact with the bottom 26 of the casing 21 due to the weight of the movable obstacle side of the protrusion 37. At this time, the upper surface portion 31 of the lock body 30 has a horizontal surface that is substantially the same height as the upper edge portion of the indoor side case portion 22, the outdoor side case portion 23, the movable shoji side case portion 24, and the frame body side case portion 25 of the casing 21. I am doing. In addition, a space is provided below the lock body 30 so that the lock body 30 can rotate, and the protrusion 34 a of the lower surface 34 is formed from the top of the claw portion 26 d provided on the bottom 26. It is in contact with the claw portion 26d on the frame body side.

施錠する際には、錠本体３０の軸突部３７より枠体側を下方に押圧すると、錠本体３０が軸突部３７を中心として回動し、軸突部３７より可動障子側の規制部３５がケーシング２１より上方に突出する。このとき、回動した錠本体３０の下面３４に設けられた突起３４ａが接触している、爪部２６ｄの頂部より枠体側の部位を錠本体３０の回動にともなって下方に押圧する。爪部２６ｄは、支持されている腕部２６ｅが弾性変形することにより下方に変位する。そして、錠本体３０の回動により突起３４ａが爪部２６ｄの頂部を越えた状態にて、錠本体３０の姿勢が維持される。また、このときケーシング２１より上方に突出した錠本体３０の規制部３５は、可動障子５の移動領域にて可動障子５の召合せ框５ａの枠体側の面と対向するように鉛直な規制面３５ａを形成しており、閉塞部３６の閉塞面３６ａは、収容部２０ａと規制部３５との間を塞ぐようにケーシング２１の上端部とほぼ同じ高さにて水平面を形成している。 When locking, when the frame body side is pressed downward from the shaft protrusion 37 of the lock body 30, the lock body 30 rotates around the shaft protrusion 37, and the restricting portion 35 on the movable shoji side from the shaft protrusion 37. Protrudes upward from the casing 21. At this time, the portion on the frame body side from the top of the claw portion 26 d, which is in contact with the protrusion 34 a provided on the lower surface 34 of the rotated lock body 30, is pressed downward as the lock body 30 rotates. The claw portion 26d is displaced downward when the supported arm portion 26e is elastically deformed. And the attitude | position of the lock main body 30 is maintained in the state in which the protrusion 34a exceeded the top part of the nail | claw part 26d by rotation of the lock main body 30. FIG. Further, at this time, the restricting portion 35 of the lock body 30 protruding upward from the casing 21 is a vertical restricting surface so as to face the frame side surface of the summing rod 5a of the movable shoji 5 in the moving region of the movable shoji 5. 35a is formed, and the closing surface 36a of the closing part 36 forms a horizontal plane at substantially the same height as the upper end part of the casing 21 so as to close the space between the housing part 20a and the restricting part 35.

施錠状態から解錠する際には、錠本体３０の軸突部３７より可動障子側を下方に押圧すると、軸突部３７を中心として回動し、軸突部３７より錠本体３０がケーシング２１内に収容される。このとき、錠本体３０の下面３４に設けられた突起３４ａが、錠本体３０の回動にともなって爪部２６ｄの頂部より可動障子側から枠体側へ爪部２６ｄを下方に押圧しつつ移動し、解錠状態となる。このとき、収容部２０ａと規制部３５との間を閉塞していた閉塞部３６の閉塞面３６ａは、収容部２０ａ内にて傾斜した状態となり、傾斜面の下端側、すなわち可動障子側には、連通孔２４ｃが位置している。 When unlocking from the locked state, when the movable shoji side is pressed downward from the shaft projection 37 of the lock body 30, the lock body 30 rotates around the shaft projection 37, and the lock body 30 is moved from the shaft projection 37 to the casing 21. Housed inside. At this time, the protrusion 34a provided on the lower surface 34 of the lock body 30 moves while pressing the claw portion 26d from the top of the claw portion 26d to the frame side from the top of the claw portion 26d as the lock body 30 rotates. , It will be unlocked. At this time, the closing surface 36a of the closing portion 36 that has closed the space between the receiving portion 20a and the restricting portion 35 is inclined in the receiving portion 20a, and on the lower end side of the inclined surface, that is, on the movable shoji side. The communication hole 24c is located.

本実施形態の建具１によれば、可動障子５の移動領域に突出して可動障子５の移動を規制する規制部３５は、解錠時には下枠１２において移動領域より下方に窪ませた収容部２０ａに収容されるので、見込み方向に建具１を見た際に補助錠２０が見え難くなっている。このため、意匠性に優れた建具１を実現することが可能である。 According to the joinery 1 of the present embodiment, the restricting portion 35 that protrudes into the moving region of the movable shoji 5 and restricts the movement of the movable shoji 5 is the housing portion 20a that is recessed below the moving region in the lower frame 12 when unlocked. Therefore, the auxiliary lock 20 is difficult to see when the joinery 1 is viewed in the prospective direction. For this reason, it is possible to implement the joinery 1 having excellent design properties.

また、補助錠２０には規制部３５と収容部２０ａとの間を閉塞するための閉塞部３６が設けられているので、施錠時に規制部３５が収容部２０ａから突出しても、収容部２０ａには空隙が形成されなない。このため、補助錠２０を下枠１２に設けてもゴミや埃により機能が阻害され難い補助錠２０を備えた建具１を提供することが可能である。 Further, since the auxiliary lock 20 is provided with a closing portion 36 for closing the space between the restricting portion 35 and the accommodating portion 20a, even if the restricting portion 35 protrudes from the accommodating portion 20a during locking, No voids are formed. For this reason, even if the auxiliary lock 20 is provided on the lower frame 12, it is possible to provide the joinery 1 provided with the auxiliary lock 20 whose function is not easily hindered by dust and dirt.

また、規制部３５が移動領域に突出した際に、閉塞部３６が下枠１２とともに平坦な面を形成して収容部２０ａと規制部３５との間を閉塞するので、たとえ閉塞部３６の上方にもゴミや埃が溜まったとしても清掃がしやすい建具１を提供することが可能である。 Further, when the restricting portion 35 protrudes into the moving region, the closing portion 36 forms a flat surface together with the lower frame 12 and closes the space between the accommodating portion 20a and the restricting portion 35. In addition, it is possible to provide a joinery 1 that is easy to clean even if dust or dust accumulates.

また、補助錠２０の解錠時には、閉塞部３６の閉塞面３６ａは下方に向かう傾斜面をなすように構成されているので、たとえ施錠時に閉塞部３６上にゴミや埃が溜まったとしても、解錠時に傾斜することにより閉塞部３６上のゴミや埃を除去することが可能である。また、収容部２０ａには、傾斜面の下端側の部位に下枠１２内に連通する連通孔２４ｃが設けられているので、閉塞部３６上のゴミや埃を収容部２０ａ内に残すことなく除去することが可能である。 In addition, when the auxiliary lock 20 is unlocked, the closing surface 36a of the closing portion 36 is configured to form a downwardly inclined surface. Therefore, even if dust or dirt accumulates on the closing portion 36 during locking, By tilting at the time of unlocking, it is possible to remove dust and dirt on the closed portion 36. In addition, since the accommodating portion 20a is provided with a communication hole 24c communicating with the lower frame 12 at a lower end side of the inclined surface, dust and dust on the closing portion 36 are not left in the accommodating portion 20a. It is possible to remove.
