　ところで、外気を車室内に取り入れるための開口など、頻繁に開閉作業が行われる可能性がある開口のホールカバー（リッド）では、リッドをフロアパネルに対してヒンジ等によって傾動自在に連結するとともに、リッドとフロアパネルとの間にリッドを閉方向に付勢する付勢部材（例えば、ねじりばね等）を設ける場合がある。この場合、リッドを傾動させてリッドを閉めた際に、リッドとフロアパネルとの間に挟まれたシールには、圧縮方向の力に加え、圧縮方向と交叉する方向（シールを倒す方向）への力が作用する。シールにシールを倒す方向への力が作用すると、パネル開口周りのシールの圧力（以下、シール圧という）を一定に保つことが難しくなり、パネル開口周りでシール圧の低い部分が生じてしまうおそれがある。また、シール圧を確保するために、付勢部材の付勢力の増大化を図ると、リッドが開き難くなる可能性がある。 By the way, in the hole cover (lid) of the opening that may be frequently opened and closed, such as an opening for taking outside air into the vehicle interior, the lid is tiltably connected to the floor panel by a hinge or the like, An urging member (for example, a torsion spring) that urges the lid in the closing direction may be provided between the lid and the floor panel. In this case, when the lid is tilted and the lid is closed, the seal sandwiched between the lid and the floor panel is applied in the direction crossing the compression direction (direction in which the seal is tilted) in addition to the force in the compression direction. The force of acts. If a force in the direction of tilting the seal acts on the seal, it will be difficult to keep the pressure of the seal around the panel opening (hereinafter referred to as seal pressure) constant, and there may be a low seal pressure around the panel opening. There is. Further, if the urging force of the urging member is increased in order to secure the seal pressure, the lid may not be easily opened.
　そこで、本開示の一つの態様は、容易に開放することができ、且つ必要なシール圧を確保することが可能なリッドの開閉構造の提供を目的とする。 Therefore, one aspect of the present disclosure aims to provide a lid opening / closing structure that can be easily opened and that can secure a necessary seal pressure.

　前記基部開口を前記一面側から塞ぐ閉位置で前記基部側環状領域と対向するリッド側環状領域を有し、前記基部の前記一面側で前記閉位置と前記基部開口を開放する開位置との間を傾動可能に前記基部に回転自在に支持されるリッドと、
　前記リッドを前記閉位置へ付勢する付勢部材と、
　断面円弧状の凸曲面を有し、前記基部の前記基部側環状領域及び前記リッドの前記リッド側環状領域の一方の領域に全周域に亘って環状に設けられ、前記リッドが前記閉位置に配置された閉状態で前記基部側環状領域及び前記リッド側環状領域の他方の領域側へ突出する環状突出部と、
　前記基部側環状領域及び前記リッド側環状領域の前記他方の領域に全周域に亘って環状に設けられ、前記閉状態で前記基部と前記リッドとに挟まれて弾性変形し、前記環状突出部の全域を含んだ状態で前記基部側環状領域及び前記リッド側環状領域の前記一方の領域に密着するシールと、を備えた
　ことを特徴とする。 In order to solve the above problems, the lid opening and closing structure of the present disclosure is:
A base having a base opening and a base-side annular region on one side surrounding the base opening;
A lid-side annular region facing the base-side annular region in a closed position that closes the base opening from the one surface side; and between the closed position and an open position that opens the base opening on the one-surface side of the base. A lid rotatably supported by the base so as to be tiltable,
A biasing member that biases the lid to the closed position;
A convex curved surface having an arcuate cross section is provided annularly over the entire circumference in one region of the base side annular region of the base and the lid side annular region of the lid, and the lid is in the closed position. An annular protrusion projecting toward the other region side of the base-side annular region and the lid-side annular region in the closed state disposed;
The annular projecting portion is provided annularly over the entire circumference in the other region of the base-side annular region and the lid-side annular region, and is elastically deformed by being sandwiched between the base and the lid in the closed state. And a seal that is in close contact with the one region of the base-side annular region and the lid-side annular region in a state including the entire region.
　また、上記開閉構造において、前記環状突出部は、前記基部側環状領域に設けられ、　前記シールは、前記リッド側環状領域に備えられていてもよい。 In the opening / closing structure, the annular protrusion may be provided in the base-side annular region, and the seal may be provided in the lid-side annular region.
　また、上記開閉構造において、前記基部開口は略矩形状の形状を有していてもよい。 Further, in the opening / closing structure, the base opening may have a substantially rectangular shape.
　また、上記開閉構造において、前記環状突出部は、前記基部側環状領域及び前記リッド側環状領域の前記一方を構成する板体が曲折して形成されていてもよい。 In the opening / closing structure, the annular projecting portion may be formed by bending a plate constituting the one of the base side annular region and the lid side annular region.
　また、上記開閉構造において、前記環状突出部は、前記基部側環状領域及び前記リッド側環状領域の前記一方の一部を厚肉に形成した厚肉部を含んでいてもよい。 In the opening / closing structure, the annular projecting portion may include a thick portion in which the one part of the base side annular region and the lid side annular region is formed thick.
　また、上記開閉構造において、前記基部は、車両のフロアパネルに設けられたフロアベントに設けられ、前記基部の形状は、前記フロアベントの走行風導入開口と略同じ大きさを有していてもよい。 Further, in the above open / close structure, the base is provided on a floor vent provided on a floor panel of a vehicle, and the shape of the base may be substantially the same as the traveling wind introduction opening of the floor vent. Good.
　上記構成では、環状突出部は、基部の基部側環状領域及びリッドのリッド側環状領域の一方の領域に設けられ、リッドが閉位置に配置された閉状態で他方の領域側へ突出する。また、シールは、他方の領域に設けられ、閉状態で基部とリッドとに挟まれて弾性変形し、環状突出部の全域を含んだ状態で一方の領域に密着する。このように、一方の領域に密着するシールのシール面のうち環状突出部に当接する部分が強く密着するので、この密着によって基部開口周りに必要なシールの圧力（以下、シール圧という）を確実に確保することができる。 In the above configuration, the annular protrusion is provided in one region of the base-side annular region of the base and the lid-side annular region of the lid, and projects toward the other region in a closed state in which the lid is disposed at the closed position. Further, the seal is provided in the other region, is elastically deformed by being sandwiched between the base portion and the lid in the closed state, and is in close contact with the one region in a state including the entire region of the annular projecting portion. In this way, the portion of the sealing surface of the seal that is in close contact with the one region is in close contact with the annular protrusion, so that the required pressure of the seal around the base opening (hereinafter referred to as seal pressure) is ensured by this close contact. Can be secured.
　また、シールのシール面のうち環状突出部に当接する部分を一方の領域に強く密着させることによってシール圧を確保するので、シールのシール面の全域を一方の領域に強く密着させる場合に比べ、付勢部材の付勢力を抑えることができ、リッドを容易に開放することができる。 In addition, since the seal pressure is secured by strongly adhering the portion of the seal surface of the seal that contacts the annular protrusion to one region, compared to the case where the entire seal surface of the seal is strongly adhered to one region, The urging force of the urging member can be suppressed, and the lid can be easily opened.
　また、閉状態ではシールが基部とリッドとに挟まれて弾性変形し、環状突出部の全域を含んだ状態で一方の領域に密着する。すなわち、閉状態では環状突出部がシールに食い込むので、シールの倒れを防止することができ、基部開口周りでシール圧を一定に保ち易い。 Also, in the closed state, the seal is elastically deformed by being sandwiched between the base portion and the lid, and is in close contact with one region including the entire area of the annular protrusion. That is, since the annular protrusion bites into the seal in the closed state, the seal can be prevented from falling down, and the seal pressure can be easily kept constant around the base opening.
　また、断面円弧状の凸曲面を有する環状突出部が一方の領域に形成されるので、一方の領域が平面である場合に比べてシールの密着面積が大きくなり、シールによる遮蔽性能が向上する。 Further, since the annular protrusion having a convex curved surface having an arcuate cross section is formed in one region, the contact area of the seal is increased as compared with the case where one region is a flat surface, and the shielding performance by the seal is improved.
　また、環状突出部が断面円弧状の凸曲面を有するので、作業者が基部とリッドとの間に指を挟んだ際の環状突出部による指の負傷を抑えることができる。 In addition, since the annular protrusion has a convex curved surface with an arc-shaped cross section, it is possible to suppress finger injury caused by the annular protrusion when the operator sandwiches the finger between the base and the lid.
　また、環状突出部を、基部の基部側環状領域の基部開口の近傍に設けた場合には、環状突出部によって基部の基部開口周りの剛性を確保することができる。 Further, when the annular protrusion is provided in the vicinity of the base opening of the base-side annular region of the base, the rigidity around the base opening of the base can be ensured by the annular protrusion.
　本開示の一つの態様によれば、リッドを容易に開閉することができ、且つ必要なシール圧を確保することができる。 According to one aspect of the present disclosure, the lid can be easily opened and closed, and a necessary seal pressure can be secured.

The spring insertion hole 40 of the locking portion 28 in the closed position is formed by connecting a center line of a later-described other end 32 of the torsion spring 16 to be inserted into the spring insertion hole 30b of the locking portion 30 of the frame plate portion 11 and a shaft rod. An imaginary plane 33 including 15 axial centers CL (indicated by a two-dot chain line 33 in FIGS. 6A and 6B) is disposed below. The stopper portion 29 extends rearward from the rear end of the bracket 27, contacts the lower surface of the floor panel 3 at the open position, and restricts movement of the lid 13 in the open position. In FIG. 5, illustration of the bracket 27, the torsion spring 16, and the locking portion 30 of the frame plate portion 11 is omitted. 6A and 6B, the virtual plane 33 is indicated by a two-dot chain line 33 for convenience, but the virtual plane 33 is a surface obtained by extending the two-dot chain line 33 in the vehicle width direction. is there.
　第２シール１４は、環状に形成されたスポンジゴム等のシール部材であって、リッド１３のリッド側環状領域２５の一部の領域に開口対向領域２４を囲むように配置されて、リッド１３の下面１３ｂに接着剤等によって固定される。すなわち、第２シール１４は、リッド側環状領域２５に全周域に亘って環状に設けられる。なお、「リッド側環状領域２５に全周域に亘って設けられる第２シール１４」とは、リッド側環状領域２５内でリッド側環状領域２５と同様に開口対向領域２４を囲むように連続して設けられる第２シール１４を意味し、リッド側環状領域２５の全域に設けられる第２シール１４に限定されるものではない。 The second seal 14 is a seal member such as sponge rubber formed in an annular shape, and is disposed so as to surround the opening facing region 24 in a partial region of the lid side annular region 25 of the lid 13. It is fixed to the lower surface 13b with an adhesive or the like. That is, the second seal 14 is provided in an annular shape over the entire circumference in the lid-side annular region 25. The “second seal 14 provided over the entire circumference of the lid-side annular region 25” is continuous in the lid-side annular region 25 so as to surround the opening facing region 24 in the same manner as the lid-side annular region 25. The second seal 14 is provided and is not limited to the second seal 14 provided over the entire lid-side annular region 25.
　第２シール１４は、リッド１３が閉位置に配置された閉状態（図５に実線で示す状態）で、後述するねじりばね１６の付勢力によって圧縮され、第２シール１４の下面であるシール面１４ａ（図６（ｂ）参照）が、枠板部１１の枠板環状領域１８に密着する。具体的には、シール面１４ａの幅方向（短手方向）の中央部が、ビード１９の凸曲面３７に強く密着し、前記中央部の両側の領域が、ビード１９の幅方向の両側でビード１９に隣接する隣接領域３６（図６（ｂ）参照）に前記中央部よりも弱く密着する。すなわち、第２シール１４は、閉状態で枠板部１１とリッド１３との間に挟まれて弾性変形し、ビード１９の全域を含んだ状態で枠板環状領域１８に密着する。閉状態での第２シール１４は、第１シール１２と共に枠板部１１の枠板環状領域１８を挟むように、枠板部１１に対して第１シール１２の反対側に配置される。リッド１３が開位置に配置された開状態（図５に２点鎖線で示す状態）では、第２シール１４のシール面１４ａは、枠板部１１の枠板環状領域１８から前上方へ離間した位置に配置される。なお、閉状態の第２シール１４のシール面１４ａは、枠板環状領域１８に完全に密着しなくてもよく、ビード１９の凸曲面３７及び隣接領域３６に面接触していればよい。例えば、ビード１９の凸曲面３７と隣接領域３６（枠板部１１の上面１１ａ）との境界である隅部に僅かな空間が生じていてもよい。 The second seal 14 is compressed by an urging force of a torsion spring 16 described later in a closed state (indicated by a solid line in FIG. 5) in which the lid 13 is disposed at a closed position, and is a seal surface that is a lower surface of the second seal 14. 14 a (see FIG. 6B) is in close contact with the frame plate annular region 18 of the frame plate portion 11. Specifically, the center portion in the width direction (short direction) of the seal surface 14 a is in close contact with the convex curved surface 37 of the bead 19, and regions on both sides of the center portion are beaded on both sides in the width direction of the bead 19. 19 is closely attached to an adjacent region 36 adjacent to 19 (see FIG. 6B) weaker than the central portion. That is, the second seal 14 is sandwiched between the frame plate portion 11 and the lid 13 in the closed state and is elastically deformed, and is in close contact with the frame plate annular region 18 in a state including the entire region of the bead 19. The second seal 14 in the closed state is arranged on the opposite side of the first seal 12 with respect to the frame plate portion 11 so as to sandwich the frame plate annular region 18 of the frame plate portion 11 together with the first seal 12. In the open state in which the lid 13 is disposed at the open position (the state indicated by a two-dot chain line in FIG. 5), the seal surface 14 a of the second seal 14 is spaced forward and upward from the frame plate annular region 18 of the frame plate part 11. Placed in position. The seal surface 14a of the second seal 14 in the closed state may not be completely in close contact with the frame plate annular region 18 as long as it is in surface contact with the convex curved surface 37 and the adjacent region 36 of the bead 19. For example, a slight space may be generated at a corner that is a boundary between the convex curved surface 37 of the bead 19 and the adjacent region 36 (the upper surface 11a of the frame plate portion 11).
　図４、図６（ａ）、及び図６（ｂ）に示すように、ねじりばね１６は、細い金属製の線状部材を車幅方向に延びる軸を中心として螺旋状に巻回して形成されるばね本体１６ａと、ねじりばね１６の一端部３１側の一側アーム部１６ｂと、ねじりばね１６の他端部３２側の他側アーム部１６ｃとを有する。ねじりばね１６の一端部３１は、一側アーム部１６ｂの先端から車幅方向の一側（本実施形態では、右側）に曲折して直線状に延び、リッド１３のブラケット２７の係止部２８のばね挿入孔４０に挿入され、ブラケット２７の係止部２８に回転自在に係止される。ねじりばね１６の他端部３２は、他側アーム部１６ｃの先端から車幅方向の他側（本実施形態では、左側）に曲折して直線状に延び、枠板部１１のばね支持部３０ａのばね挿入孔３０ｂに挿入され、枠板部１１の係止部３０に回転自在に係止される。ねじりばね１６の一側アーム部１６ｂと他側アーム部１６ｃとは、側面視においてばね本体１６ａから略Ｖ字状に互いに交叉することなく離間して拡がる方向へ延びる。ねじりばね１６が一側アーム部１６ｂと他側アーム部１６ｃとが近づく方向に捩られると、ねじりばね１６には一側アーム部１６ｂと他側アーム部１６ｃとを離間させる方向への弾性力が発生する。ねじりばね１６は、閉位置と開位置との間では、常に一側アーム部１６ｂと他側アーム部１６ｃとが近づく方向に捩られた状態で、枠板部１１とリッド１３とに連結されている。 As shown in FIGS. 4, 6 (a), and 6 (b), the torsion spring 16 is formed by spirally winding a thin metal linear member around an axis extending in the vehicle width direction. A spring body 16 a, a one-side arm portion 16 b on the one end portion 31 side of the torsion spring 16, and an other-side arm portion 16 c on the other end portion 32 side of the torsion spring 16.

The one-side arm portion 16b and the other-side arm portion 16c of the torsion spring 16 extend away from the spring body 16a in a substantially V shape in a side view so as to be separated and expanded. When the torsion spring 16 is twisted in the direction in which the one-side arm portion 16b and the other-side arm portion 16c approach each other, the torsion spring 16 has an elastic force in a direction to separate the one-side arm portion 16b and the other-side arm portion 16c. appear. The torsion spring 16 is connected to the frame plate portion 11 and the lid 13 in a state where the one side arm portion 16b and the other side arm portion 16c are always twisted between the closed position and the open position. Yes.
　次に、閉状態のフロアベント１０と、開状態のフロアベント１０とについて説明する。 Next, the closed floor vent 10 and the opened floor vent 10 will be described.
　図６（ａ）に示すように、閉状態のフロアベント１０は、ねじりばね１６の一端部３１（図４参照）が、上記仮想平面３３よりも下方に配置され、ねじりばね１６が、リッド１３のブラケット２７の係止部２８を枠板部１１のばね支持部３０ａ側から前下方（図中の矢印３４が示す方向）へ付勢し、この付勢によってリッド１３を閉方向に付勢している。第２シール１４は、ねじりばね１６の付勢力によって枠板部１１の枠板環状領域１８側へ押圧され、リッド１３と枠板部１１とに挟まれて弾性変形する。第２シール１４のシール面１４ａ（図６（ｂ）参照）は、弾性変形し、枠板環状領域１８のビード１９の凸曲面３７（図６（ｂ）参照）及びビード１９の両側の隣接領域３６（図６（ｂ）参照）に密着する。リッド１３は、枠板部１１の開口１７及びフロアパネル３の走行風導入開口５を上側から塞ぎ、走行風導入開口５から車室４内への走行風の流入を阻止する。 As shown in FIG. 6A, in the closed floor vent 10, one end 31 (see FIG. 4) of the torsion spring 16 is disposed below the virtual plane 33, and the torsion spring 16 is connected to the lid 13. The urging portion 28 of the bracket 27 is biased forward and downward (in the direction indicated by the arrow 34 in the figure) from the spring support portion 30a side of the frame plate portion 11, and the lid 13 is urged in the closing direction by this urging. ing. The second seal 14 is pressed toward the frame plate annular region 18 side of the frame plate portion 11 by the urging force of the torsion spring 16, and is elastically deformed by being sandwiched between the lid 13 and the frame plate portion 11. The seal surface 14a (see FIG. 6B) of the second seal 14 is elastically deformed, and the convex curved surface 37 (see FIG. 6B) of the bead 19 in the frame plate annular region 18 and adjacent regions on both sides of the bead 19 are. 36 (see FIG. 6B). The lid 13 closes the opening 17 of the frame plate part 11 and the traveling wind introduction opening 5 of the floor panel 3 from above, and prevents the traveling wind from flowing into the passenger compartment 4 from the traveling wind introduction opening 5.
　図６（ｂ）に示すように、開状態のフロアベント１０は、ねじりばね１６の一端部３１（図４参照）が、上記仮想平面３３よりも上方に配置され、ねじりばね１６が、リッド１３のブラケット２７の係止部２８を枠板部１１のばね支持部３０ａ側から前上方（図中の矢印３５が示す方向）へ付勢し、この付勢によってリッド１３を開方向に付勢している。ストッパ部２９は、フロアパネル３の下面に当接し、ねじりばね１６の付勢力に抗してリッド１３の開方向への移動を開位置に規制する。第２シール１４のシール面１４ａは、枠板部１１の枠板環状領域１８から前上方へ離間する。リッド１３は、枠板部１１の開口１７及びフロアパネル３の走行風導入開口５を開放し、走行風導入開口５から車室４内への走行風の流入を許容する。 As shown in FIG. 6B, in the opened floor vent 10, one end 31 (see FIG. 4) of the torsion spring 16 is disposed above the virtual plane 33, and the torsion spring 16 is connected to the lid 13. The urging portion 28 of the bracket 27 is biased forward and upward (in the direction indicated by the arrow 35 in the figure) from the spring support portion 30a side of the frame plate portion 11, and the lid 13 is urged in the opening direction by this urging. ing. The stopper portion 29 is in contact with the lower surface of the floor panel 3 and restricts the movement of the lid 13 in the opening direction against the biasing force of the torsion spring 16. The seal surface 14 a of the second seal 14 is spaced forward and upward from the frame plate annular region 18 of the frame plate part 11. The lid 13 opens the opening 17 of the frame plate portion 11 and the traveling wind introduction opening 5 of the floor panel 3 and allows the traveling wind to flow into the passenger compartment 4 from the traveling wind introduction opening 5.
　次に、フロアベント１０のリッド１３の動きについて説明する。 Next, the movement of the lid 13 of the floor vent 10 will be described.
　閉状態のフロアベント１０の閉位置のリッド１３を開位置へ傾動させて、フロアベント１０を開状態にする際には、乗員は、操作部２６を上方へ押し上げる。操作部２６を上方へ押し上げる際、ねじりばね１６の一端部３１が、上記仮想平面３３よりも下方にある間は、乗員は、ねじりばね１６の付勢力に抗してリッド１３を上方へ傾動させる。ねじりばね１６の一端部３１が、上記仮想平面３３よりも上方へ移動すると、そこからリッド１３がねじりばね１６の付勢力によって開位置へ移動し、ストッパ部２９がフロアパネル３の下面に当接する。第２シール１４は、弾性変形した状態からその弾性力によって復元する。 When the lid 13 in the closed position of the closed floor vent 10 is tilted to the open position to open the floor vent 10, the occupant pushes up the operation unit 26 upward. When the operation portion 26 is pushed upward, the occupant tilts the lid 13 upward against the urging force of the torsion spring 16 while the one end 31 of the torsion spring 16 is below the virtual plane 33. . When the one end portion 31 of the torsion spring 16 moves above the virtual plane 33, the lid 13 moves to the open position by the urging force of the torsion spring 16, and the stopper portion 29 comes into contact with the lower surface of the floor panel 3. . The second seal 14 is restored by its elastic force from the elastically deformed state.
　開状態のフロアベント１０の開位置のリッド１３を閉位置へ傾動させて、フロアベント１０を閉状態にする際には、乗員は、操作部２６を下方へ押し下げる。操作部２６を下方へ押し下げる際、ねじりばね１６の一端部３１が、上記仮想平面３３よりも上方にある間は、乗員は、ねじりばね１６の付勢力に抗してリッド１３を下方へ傾動させる。ねじりばね１６の一端部３１が、上記仮想平面３３よりも下方へ移動すると、そこからリッド１３がねじりばね１６の付勢力によって閉位置へ移動し、第２シール１４のシール面１４ａが枠板部１１の枠板環状領域１８に密着する。 When the lid 13 in the open position of the floor vent 10 in the open state is tilted to the closed position to place the floor vent 10 in the closed state, the occupant pushes down the operation unit 26 downward. When the operation portion 26 is pushed downward, the occupant tilts the lid 13 downward against the urging force of the torsion spring 16 while the one end 31 of the torsion spring 16 is above the virtual plane 33. . When the one end portion 31 of the torsion spring 16 moves below the virtual plane 33, the lid 13 moves to the closed position by the urging force of the torsion spring 16, and the seal surface 14a of the second seal 14 is moved to the frame plate portion. It closely adheres to the 11 frame plate annular regions 18.
　上記のように構成されたフロアベント１０では、ビード１９が、枠板部１１の枠板環状領域１８に設けられ、枠板部１１の上面１１ａに対して略垂直に上側へ突出する。すなわち、ビード１９は、閉状態でリッド１３のリッド側環状領域２５側へ突出する。また、第２シール１４が、リッド１３のリッド側環状領域２５に設けられて閉状態で枠板部１１とリッド１３との間に挟まれて弾性変形し、第２シール１４のシール面１４ａが、ビード１９及びビード１９の両側の隣接領域３６に密着する。このように、第２シール１４のシール面１４ａのうちビード１９に当接する部分が枠板環状領域１８に強く密着するので、この密着によって枠板部１１の開口１７周りに必要な第２シール１４の圧力（以下、シール圧という）を確実に確保することができる。 In the floor vent 10 configured as described above, the bead 19 is provided in the frame plate annular region 18 of the frame plate portion 11 and protrudes upward substantially perpendicularly to the upper surface 11a of the frame plate portion 11. That is, the bead 19 protrudes toward the lid-side annular region 25 side of the lid 13 in the closed state. Further, the second seal 14 is provided in the lid-side annular region 25 of the lid 13 and is sandwiched between the frame plate portion 11 and the lid 13 in the closed state and elastically deforms, and the seal surface 14a of the second seal 14 is The bead 19 and the adjacent regions 36 on both sides of the bead 19 are in close contact with each other. Thus, the portion of the seal surface 14a of the second seal 14 that abuts the bead 19 is in close contact with the frame plate annular region 18, so that the second seal 14 required around the opening 17 of the frame plate portion 11 by this close contact. The pressure (hereinafter referred to as seal pressure) can be ensured reliably.
　また、第２シール１４のシール面１４ａのうちビード１９に当接する部分を枠板環状領域１８に強く密着させることによってシール圧を確保するので、シール面１４ａの全域を枠板環状領域１８に強く密着させる場合に比べ、ねじりばね１６の付勢力を抑えることができ、リッド１３の開放を容易に行うことができる。 In addition, since the seal pressure is secured by strongly adhering the portion of the seal surface 14a of the second seal 14 that contacts the bead 19 to the frame plate annular region 18, the entire area of the seal surface 14a is strongly against the frame plate annular region 18. Compared with the case where it adheres, the urging | biasing force of the torsion spring 16 can be suppressed, and the lid | cover 13 can be open | released easily.
　また、閉状態では、第２シール１４が、枠板部１１とリッド１３との間に挟まれて弾性変形し、ビード１９の全域を含んだ状態で枠板部１１の枠板環状領域１８に密着する。すなわち、閉状態ではビード１９が第２シール１４に食い込んで第２シール１４が倒れ難いので、枠板部１１の開口１７周りでシール圧を一定に保ち易い。 Further, in the closed state, the second seal 14 is sandwiched between the frame plate portion 11 and the lid 13 and elastically deformed, and in the state including the entire area of the bead 19, the second seal 14 enters the frame plate annular region 18 of the frame plate portion 11. In close contact. That is, in the closed state, the bead 19 bites into the second seal 14 and the second seal 14 is unlikely to fall down, so that the seal pressure can be easily maintained around the opening 17 of the frame plate portion 11.
　また、断面円弧状の凸曲面３７を有するビード１９が枠板部１１の枠板環状領域１８に形成されるので、枠板環状領域１８が平面である場合に比べて第２シール１４の密着面積が大きくなり、第２シール１４による遮蔽性能が向上する。 Further, since the bead 19 having the convex curved surface 37 having an arcuate cross section is formed in the frame plate annular region 18 of the frame plate portion 11, the contact area of the second seal 14 is larger than when the frame plate annular region 18 is flat. And the shielding performance by the second seal 14 is improved.
　また、ビード１９が断面円弧状の凸曲面３７を有するので、例えば、作業者（乗員等）がリッド１３と枠板部１１との間に指を挟んだ際のビード１９による指の負傷を抑えることができる。 Further, since the bead 19 has a convex curved surface 37 having an arc-shaped cross section, for example, an operator (occupant or the like) suppresses finger injury caused by the bead 19 when the finger is sandwiched between the lid 13 and the frame plate part 11. be able to.
　また、ビード１９を、枠板部１１の枠板環状領域１８のうち開口１７の近傍に配置するので、ビード１９によって枠板部１１の開口１７周りの剛性を確保することができる。 Further, since the bead 19 is disposed in the vicinity of the opening 17 in the frame plate annular region 18 of the frame plate part 11, the bead 19 can ensure the rigidity around the opening 17 of the frame plate part 11.
　また、閉状態での第２シール１４の枠板部１１に対する反対側には、第１シール１２が配置されて枠板部１１とフロアパネル３との間に挟まれている。このため、枠板部１１とフロアパネル３とが離間して配置されても、第１シール１２を介してフロアパネル３が枠板部１１の枠板環状領域１８を下方から支持するので、閉状態でねじりばね１６の付勢力によって枠板部１１の枠板環状領域１８が下方へ押圧されても、枠板部１１の枠板環状領域１８が下方へ変形し難く、閉状態での第２シール１４のシール圧を確保することができる。 The first seal 12 is disposed on the opposite side of the second seal 14 to the frame plate portion 11 in the closed state, and is sandwiched between the frame plate portion 11 and the floor panel 3. For this reason, even if the frame plate portion 11 and the floor panel 3 are spaced apart from each other, the floor panel 3 supports the frame plate annular region 18 of the frame plate portion 11 from below via the first seal 12, so that the Even if the frame plate annular region 18 of the frame plate portion 11 is pressed downward by the urging force of the torsion spring 16 in the state, the frame plate annular region 18 of the frame plate portion 11 is hardly deformed downward, and the second state in the closed state. The seal pressure of the seal 14 can be ensured.
　従って、本実施形態によれば、リッド１３を容易に開放することができ、且つ必要なシール圧を確保することができる。 Therefore, according to the present embodiment, the lid 13 can be easily opened and a necessary sealing pressure can be secured.
　なお、本実施形態では、リッド１３に固定されるブラケット２７の係止部２８と、枠板部１１のばね支持部３０ａとの間にねじりばね（付勢部材）１６を配置し、このねじりばね１６よって、所定の位置（ねじりばね１６の一端部３１と上記仮想平面３３とが重なる位置）を境にしてリッド１３を開方向又は閉方向の双方へ付勢したが、付勢部材はこれに限定されるものではない。例えば、枠板部１１とリッド１３とを回転自在に連結するヒンジ部に、リッド１３を閉方向のみへ付勢するねじりばね等の付勢部材を設けてもよい。この場合、リッド１３を開位置に保持する機構やストッパ部材等を設けてもよい。 In the present embodiment, a torsion spring (biasing member) 16 is disposed between the locking portion 28 of the bracket 27 fixed to the lid 13 and the spring support portion 30a of the frame plate portion 11, and this torsion spring. Accordingly, the lid 13 is urged in both the opening direction and the closing direction at a predetermined position (a position where the one end portion 31 of the torsion spring 16 and the imaginary plane 33 overlap). It is not limited. For example, an urging member such as a torsion spring that urges the lid 13 only in the closing direction may be provided at the hinge portion that rotatably connects the frame plate portion 11 and the lid 13. In this case, a mechanism or a stopper member for holding the lid 13 in the open position may be provided.
　また、本実施形態では、枠板部１１の枠板環状領域（一方の領域）１８にビード（環状突出部）１９を設け、リッド１３のリッド側環状領域（他方の領域）２５に第２シール１４を固定したが、リッド１３のリッド側環状領域（一方の領域）２５にビード１９を設け、枠板部１１の枠板環状領域（他方の領域）１８に第２シール１４を固定してもよい。この場合、ビード１９は、閉状態で枠板環状領域１８側へ突出する。また、環状突出部は、プレス加工等によって板体（本実施形態では、枠板部１１）を曲折して形成したビード１９に限定されず、例えば、枠板環状領域１８及びリッド側環状領域２５の一方の領域の一部を厚肉に形成して閉状態で他方の領域側へ突出する厚肉部を設けてもよく、該厚肉部が断面円弧状の凸曲面を有してもよい。 Further, in the present embodiment, a bead (annular protrusion) 19 is provided in the frame plate annular region (one region) 18 of the frame plate portion 11, and the second seal is provided in the lid side annular region (the other region) 25 of the lid 13. 14 is fixed, but the bead 19 is provided in the lid side annular region (one region) 25 of the lid 13, and the second seal 14 is fixed to the frame plate annular region (the other region) 18 of the frame plate part 11. Good. In this case, the bead 19 protrudes toward the frame plate annular region 18 in the closed state. Further, the annular projecting portion is not limited to the bead 19 formed by bending a plate body (in this embodiment, the frame plate portion 11) by press working or the like, for example, the frame plate annular region 18 and the lid side annular region 25. A part of one of the regions may be formed thick and a thick part protruding toward the other region in the closed state may be provided, and the thick part may have a convex curved surface having an arcuate cross section .
　また、本実施形態では、フロアパネル３に固定される枠板部１１を設けたが、これに限定されるものではない。例えば、枠板部１１を設けることなく、リッド１３が、フロアパネル（基部）３に回転自在に支持されてフロアパネル３の走行風導入開口（基部開口）５を開閉自在に閉止してもよく、フロアパネル３の走行風導入開口５を囲む基部側環状領域が、閉状態でリッド１３のリッド側環状領域２５に対向してもよい。 In the present embodiment, the frame plate portion 11 fixed to the floor panel 3 is provided, but the present invention is not limited to this. For example, the lid 13 may be rotatably supported by the floor panel (base portion) 3 without providing the frame plate portion 11 and close the traveling wind introduction opening (base opening) 5 of the floor panel 3 so as to be freely opened and closed. The base side annular region surrounding the traveling wind introduction opening 5 of the floor panel 3 may face the lid side annular region 25 of the lid 13 in the closed state.
　また、本実施形態では、フロアベント１０を、前上方から後下方へ向かって僅かに傾斜するフロアパネル３の前端部の車幅方向中央部に固定したが、フロアベント１０を固定する位置及びフロアパネル３の傾斜は、これに限定されるものではない。 In the present embodiment, the floor vent 10 is fixed to the center in the vehicle width direction of the front end of the floor panel 3 that is slightly inclined from the front upper side to the rear lower side. The inclination of the panel 3 is not limited to this.
