This application is based on Japanese Patent Application No. 2014-134469 filed on June 30, 2014, the disclosure of which is incorporated herein by reference.

The present disclosure relates to a door member, a door device, and a vehicle air conditioner using the door member.

2. Description of the Related Art Conventionally, in a vehicle air conditioner, a first door substrate extending in a circumferential direction centered on a rotation axis, and provided in a circumferential direction with respect to the first door substrate and extending in a circumferential direction centered on the rotation axis. Some include a rotary door having a second door substrate and a door opening provided between the first and second door substrates (see, for example, Patent Document 1).

JP 2009-214869 A

However, according to the examination of the inventors of the present disclosure, in the above vehicle air conditioner, when the end of one side in the circumferential direction of the film hits the inner wall of the case as the rotary door rotates, the force applied to the case from the film Variations occur. For this reason, sliding noise may be generated by sliding between the end portion on one side in the circumferential direction of the film and the inner wall of the case, or the sliding noise may vary.

The inventor of the present disclosure winds the film from the outer side in the radial direction of the door substrate to the circumferential end of the door substrate, as shown in FIG. 14 (comparative example), in order to alleviate the sliding noise and its fluctuation. It was considered that the end of one side in the circumferential direction of the film 1 was arranged on the inner side in the radial direction of the door substrate by bending the inner side in the radial direction of the door substrate.

In this case, an elastic force is generated in the film, and the film is deformed so that the bending start point of the film is displaced inward in the radial direction as time passes. Therefore, a gap may be generated between the film and the inner wall of the case. Due to this gap, there is a possibility that a sealing failure may occur in which the film cannot seal any one blowing opening. That is, there is a possibility that sealing of the blowout opening (opening) is impaired due to the displacement of the bending start point in the film.

The present disclosure provides a door member, a door device, and a vehicle air conditioner using the door member, in which the deterioration of the sealing performance of the opening due to the displacement of the bending start point of the film is obviated. With the goal.

The door member of the present disclosure includes a door substrate, a film, and a protrusion. A door board | substrate is arrange | positioned in the case which has a blowing opening part, opens and closes a blowing opening part by displacement, and has plate shape. A film is arrange | positioned in a case, is arrange | positioned so that the blower opening part side may be followed among door doors, and the blower opening part is sealed in the state which closed the blower opening part. The protrusion is formed so as to protrude from the end in the plate surface direction of the door substrate toward the blowout opening. The film is wound around the protrusion from the outlet opening side of the door substrate, and is bent to the opposite side of the door substrate from the outlet opening.

According to the door member of the present disclosure, it is possible to suppress the bending start point from being displaced by the elastic force of the film. For this reason, it can suppress that a clearance gap arises between a case and a film. Thereby, it can suppress beforehand that the displacement of a bending start point arises among films, and impairing the sealing performance of an opening part.

The door device of the present disclosure includes the above door member, case, and rotating shaft. The rotating shaft is rotatably supported by the case. The door substrate includes a first door substrate and a second door substrate whose plate surface direction is a circumferential direction around the rotation axis. The film includes a first film portion disposed on the first door substrate and a second film portion disposed on the second door substrate. The first door substrate and the second door substrate are arranged in a circumferential direction. A door opening is formed between the first door substrate and the second door substrate. The first and second door substrates, the first and second film portions, and the door opening rotate as the rotation shaft rotates. When either one of the first and second door substrates closes the blowout opening, the film portion disposed on the one of the first and second film portions has the blowout opening. It is designed to be sealed. The blowout opening is opened in a state where the door opening communicates with the blowout opening.

The vehicle air conditioner of the present disclosure includes the door device described above. The blowout opening of the case is arranged to blow air into the vehicle interior of the vehicle. The vehicle interior is air-conditioned by air blown into the vehicle interior from the blowout opening with the door substrate opened.

According to this, it is possible to suppress the impairing of the airtightness of the blowout opening constituting the air conditioner.

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. FIG. 1 shows an embodiment of a vehicle air conditioner according to the present disclosure. FIG. 1 is a diagram showing a schematic configuration of a vehicle air conditioner. In FIG. 1, the up, down, left, and right arrows indicate the directions when the vehicle air conditioner is mounted on the vehicle.

The vehicle air conditioner includes an air conditioning unit 20. The air conditioning unit 20 includes a case 21, a cooling heat exchanger 22, a heating heat exchanger 23, an air mix door 24, and a door device 2500. An air inlet 21a is provided on the front side of the case 21 in the traveling direction of the vehicle. Air blown from the blower is introduced into the air inlet 21a. The blower is disposed in the left-right direction (vehicle width direction) of the vehicle with respect to the air conditioning unit 20.

The cooling heat exchanger 22 is disposed in the rear side of the case 21 in the traveling direction of the vehicle at the air inlet 21a. The cooling heat exchanger 22 constitutes a well-known refrigeration cycle apparatus that circulates refrigerant together with a compressor, a condenser, and an expansion valve, and cools air introduced into the air inlet 21a by evaporating the refrigerant. .

The heating heat exchanger 23 is disposed on the rear side in the traveling direction with respect to the cooling heat exchanger 22 in the case 21, and heats the cool air blown from the cooling heat exchanger 22 by engine cooling water (hot water). To do. A hot air passage 26 a that guides the warm air blown from the heating heat exchanger 23 to the air mixing chamber 27 is formed on the rear side of the case 21 in the traveling direction with respect to the heating heat exchanger 23.

In the case 21, a bypass passage 26 is provided on the improvement side of the heat exchanger 23 with respect to the heating heat exchanger 23.

The air mix door 24 is disposed on the upper side of the heat exchanger 23 for heating. The air mix door 24 is formed so that the cross section thereof has a substantially arc shape. The air mix door 24 is rotatably supported by the case 21.

The air mix door 24 changes the ratio of the opening area of the bypass passage 26 and the opening area of the hot air passage 26a depending on its position. Thus, the air mix door 24 can adjust the temperature of the air blown into the vehicle interior by adjusting the ratio of the amount of air flowing through the bypass passage 26 and the amount of air flowing through the hot air passage 26a. FIG. 1 shows a max cool state in which the air mix door 24 fully closes the hot air passage 26 a and fully opens the bypass passage 26.

The door device 2500 includes at least a case 21 and a mode door (door member) 25 disposed inside the case 21.

The mode door 25 is disposed above the air mixing chamber 27 in the case 21. In other words, the mode door 25 is located downstream of the air mixing chamber 27 in the air flow direction of the case 21. The mode door 25 is rotatably supported with respect to the case 21 by a rotating shaft 25a (see FIG. 2). The mode door 25 is driven by, for example, an electric motor (not shown).

In the present embodiment, the face blowing opening 21c is arranged on one side in the circumferential direction with respect to the defroster blowing opening 21b. The foot blowing opening 21d is arranged on one side in the circumferential direction with respect to the face blowing opening 21c.

The face blowout opening 21c is a blowout opening that blows conditioned air toward the upper body of the passenger in the passenger compartment. The foot blowout opening 21d is a blowout opening that blows conditioned air toward the lower body of the occupant. The defroster blowing opening 21b is a blowing opening that blows conditioned air toward the inner surface of the window glass in the vehicle interior.

The mode door 25 causes the mixed air from the air mixing chamber 27 to flow to any one of the

outlet openings

21b, 21c, and 21d as it rotates. The mode door 25 of the present embodiment constitutes a rotary door formed in a substantially cylindrical shape.

Next, a specific structure of the mode door 25 according to the present embodiment will be described with reference to FIGS. FIG. 2 is a perspective view of the mode door 25. 1 and 3 are sectional views of the mode door 25 as viewed from one side in the axial direction.

The door side walls 250a and 250b are each formed in a disk shape, and are arranged with an interval in the vehicle width direction (perpendicular to the paper surface in FIG. 1). A rotary shaft 25a is disposed on each of the door side walls 250a and 250b. The rotary shaft 25a is formed so as to protrude outward (that is, in the vehicle width direction) from the door side walls 250a and 250b.

The door substrates 251 and 252 are each formed in a plate shape extending in the circumferential direction around the rotation shaft 25a, as shown in FIGS. That is, the

door substrates

outlet openings

21b, 21c, and 21d side) from the end Z1 on one side in the circumferential direction of the outer peripheral surface of the door substrate 251 in the axial direction. It is formed to protrude. In other words, the door substrate 251 has the protrusion 30a that protrudes from the end Z1 so as to bend outward in the radial direction. Specifically, the protrusion 30a is bent at the end Z1 so that the tip Z3 of the protrusion 30a is located on the outer side in the radial direction than the end Z1. Further, the protruding portion 30 a extends from one end of the door substrate 251 in the axial direction to the other end. The axial direction is the axial direction of the rotating shaft 25a.

The protrusion (second protrusion) 30b is formed so as to protrude from the end Z2 on the other circumferential side of the outer peripheral surface of the door substrate 251 to the outer peripheral side in the axial direction. In other words, the door substrate 251 has the protruding portion 30b that protrudes from the end portion Z2 so as to be bent radially outward. Specifically, the protrusion 30b is bent at the end Z2 so that the tip Z4 of the protrusion 30b is positioned on the outer side in the radial direction than the end Z2. Further, the protrusion 30b extends from one end of the door substrate 251 in the axial direction to the other end. Here, the outer peripheral side is the outer side in the radial direction centering on the rotary shafts 25a and 25b. The inner peripheral side is a radially inner side centering on the rotary shafts 25a and 25b.

FIG. 4A shows a partially enlarged view of the protrusion 30a. The protrusion 30a has a first part (first side face) 31a and a second part (second side face) 31b. The 2nd site | part 31b is located in the circumferential direction other side among the projection parts 30a, and the 2nd site | part 31b is located in the circumferential direction one side among the projection parts 30a. Furthermore, the 1st site | part 31a is located in the radial direction outer side of the 2nd site | part 32a. The 1st site | part 31a is formed in the cross-section circular arc shape which becomes convex on the circumferential direction one side. The 1st site | part 31a means the part between the edge part Z1 of the circumferential direction one side among the outer peripheral surfaces of the door board | substrate 251, and the front-end | tip Z3 of the projection part 30a. The 2nd site | part 31b is formed in the cross-sectional circular arc shape which becomes convex on the circumferential direction one side.

The first portion 31c is formed in a circular arc shape that is convex toward the other side in the circumferential direction. The 1st site | part 31c means the part between the edge part Z2 of the circumferential direction other side and the front-end | tip Z4 of the projection part 30b among the outer peripheral surfaces of the door board | substrate 251. FIG. The second portion 31d is formed in a circular arc shape that is convex on the other circumferential side.

Prior to the present disclosure, the inventor of the present disclosure uses an end 1c on one side in the circumferential direction of the film 1 as a door substrate, as shown in FIG. It was considered to arrange them on the inner side in the radial direction. Specifically, the film 1 is wound from the outer side in the radial direction of the door substrate 2 to the circumferential end of the door substrate 2 and bent toward the inner side in the radial direction of the door substrate 2.

Here, a position at which bending starts from the radially outer side of the door substrate 2 to the radially inner side in the radially outer side 1a (see FIG. 15) of the film 1 is defined as a bending start point Y, and an arbitrary reference point of the door substrate 2 Is a reference point K. The length measured between the reference point K and the bending start point Y along the radially outer side (that is, the blowout opening side) 1a of the film 1 is La, and the reference point A and the door substrate 2 circle The length measured along the radial direction inner side (that is, the door substrate 2 side) 1b of the film 1 is defined as Lb.

Since the door substrate 2 is formed in an arc shape as described above, the length La is longer than the length Lb. For this reason, the elastic force which makes the difference of length La and Lb small arises in the film 1. FIG. Thereby, with the passage of time, the film 1 is deformed so that the bending start point Y is displaced radially inward by the elastic force of the film 1. For this reason, the displacement of the bending start point Y is not uniquely determined. Therefore, a gap may be generated between the film 1 and the inner wall of the case. Thereby, in the state which closed any one blowing face opening part by the door board | substrate 2 among the face blowing opening part, the defroster blowing opening part, and the foot blowing opening part, it originates in a clearance gap, and the film 1 is the said any 1 There is a risk that a sealing failure may occur in which the two outlet openings cannot be sealed. That is, there is a risk of impairing the airtightness of the blowout opening (opening) due to the displacement of the bending start point in the film 1.

FIG. 5 shows the door substrate 251 and the film 254 of this embodiment. FIG. 6 shows the dimensional relationship on one side in the circumferential direction of the door substrate 251 and the film 254. In FIG. 6, hatching is omitted to clarify the illustration of the reference numerals and the like.

In the present embodiment, the circumferential intermediate portion of the film 254 is disposed along the outer peripheral surface of the door substrate 251 as shown in FIG. One side in the circumferential direction of the film 254 is wound around the protrusion 30 a by elastic deformation and is bent from the outer peripheral side of the door substrate 251 to the inner peripheral side of the door substrate 251. That is, the end of one side in the circumferential direction of the film 254 is located on the inner peripheral side of the door substrate 251.

The other circumferential side of the film 254 is wound around the protrusion 30b by elastic deformation and is bent from the outer peripheral side of the door substrate 251 to the inner peripheral side of the door substrate 251. That is, the end on the other circumferential side of the film 254 is located on the inner peripheral side of the door substrate 251.

Here, on one side in the circumferential direction of the outer peripheral surface of the film 254, a position at which bending starts from the outer peripheral side of the door substrate 251 to the inner peripheral side of the door substrate 251 is the bending start point (first bending start point) Y1. (See FIG. 5).

In the present embodiment, an intermediate position between one end Z1 in the circumferential direction and the other end Z2 in the circumferential direction on the outer peripheral surface (opening side surface) of the door substrate 251 is the door substrate. An arbitrary reference point K of 251 (see FIG. 5) is used. Further, a position corresponding to the reference point (first reference point) K in the radial direction on the outer peripheral surface (surface on the opening side) of the film 254 is set as a reference point (second reference point) Kf.

The length in the circumferential direction measured along the outer peripheral surface of the door substrate 251 between the reference point K and one end Z1 in the circumferential direction of the door substrate 251 is a length LA (second length: FIG. 6).

The length in the circumferential direction measured along the outer peripheral surface of the film 254 between the reference point Kf and the position X1 on the outer peripheral surface of the film 254 is defined as a length L2 (see FIG. 6). The position X1 is set so that the length L2 is the same as the length LA. And the length of the circumferential direction measured along the outer peripheral surface of the film 254 between the position X1 and the bending start point Y1 is set to length J2a.

The length measured along the side surface 50a on the other circumferential side of the protrusion 30a between the end Z1 on one side in the circumferential direction of the door substrate 251 and the tip Z3 of the protrusion 30a is a length J1a ( 3rd length). And the protrusion part 30a is formed so that length J1a and length J2a may become the same.

That is, the length in the circumferential direction measured along the outer peripheral surface of the film 254 between the reference point Kf on the outer peripheral surface of the film 254 and the bending start point Y1 is the length L1 (outer path length: first As a result, the protrusion 30a is formed such that the length (LA + J1a) obtained by adding the length LA and the length J1a is the same as the length L1 (L1 = LA + J1a). In other words, the length L1 is longer than the length LA. As a result, the bending start point Y1 is located at a position further away from the first reference point Kf in the circumferential direction. That is, the bending start point Y1 comes closer to the tip Z3 of the protrusion 30a.

When the film 254 is wound around the protrusion 30a, the film 254 is deformed by the stress received from the protrusion 30a, and there is a possibility that a gap is formed between the film 254 and the door substrate 251. However, the stress that the film 254 receives from the protrusion 30a decreases as the bending start point Y1 approaches the tip Z3 of the protrusion 30a. As a result, the gap formed between the film 254 and the door substrate 251 can be reduced.

Further, the length measured from the reference point K of the door substrate 251 through the end Z1 to the tip Z3 of the protrusion 30a along the inner peripheral surface side of the film 254 is a length LX (inner path length). : 7th length). At this time, the length LX corresponds to a length (LA + J1a) obtained by adding the length LA and the length J1a (LX = LA + J1a). That is, the length LX and the length L1 can be matched.

In the present embodiment, assuming that one end in the circumferential direction on the inner peripheral surface of the film 254 is an end W1, the length between the bending start point Y1 and the end W1 of the film 254 in the film 254 is long. The length is shortened and the length J1a is lengthened.

Next, the other circumferential side of the film 254 will be described with reference to FIG. FIG. 7 shows a dimensional relationship between the door substrate 251 and the film 254 on the other side in the circumferential direction. In FIG. 7, hatching is omitted for clarity of illustration of symbols and the like.

On the other circumferential side of the outer peripheral surface of the film 254, the bending start point (second bending start point) Y2 is a position where the bending starts from the outer peripheral side of the door substrate 251 to the inner peripheral side of the door substrate 251 (FIG. 5). FIG. 7).

The circumferential length measured along the outer peripheral surface of the door substrate 251 between an arbitrary reference point K on the outer peripheral surface of the door substrate 251 and the end Z2 on the other circumferential side of the door substrate 251 is Length LB (fifth length).

The length in the circumferential direction measured along the outer peripheral surface of the film 254 between the reference point Kf of the film 254 and the position X2 on the outer peripheral surface of the film 254 is a length L4, and the length L4 is a length LB. Position X2 is set to be the same. And the length of the circumferential direction measured along the outer peripheral surface of the film 254 between the position X2 and the bending start point Y2 is set to length J2b.

The length measured along the side surface 50b on one circumferential side of the projection 30b between the end Z2 on the other circumferential side of the door substrate 251 and the tip Z4 of the projection 30b is a length J1b ( 6th length). And the protrusion part 30b is formed so that length J1b and length J2b may become the same.

That is, the length in the circumferential direction measured along the outer peripheral surface of the film 254 between the reference point Kf of the film 254 and the bending start point Y2 is defined as a length L3 (outer path length: fourth length). . At this time, the protrusion 30b is formed such that the length (LB + J1b) obtained by adding the length LB and the length J1b is the same as the length L3 (L3 = LB + J1b). In other words, the length L3 is longer than the length LB. Accordingly, the bending start point Y2 is located at a position further away from the first reference point Kf in the circumferential direction. That is, the bending start point Y2 comes closer to the tip Z4 of the protrusion 30b.

When the film 254 is wound around the protrusion 30b, the film 254 is deformed by the stress received from the protrusion 30b, and there is a possibility that a gap is formed between the film 254 and the door substrate 251. However, as described above, the stress that the film 254 receives from the protrusion 30b is reduced by the bending start point Y2 being closer to the tip Z4 of the protrusion 30b. Therefore, the gap formed between the film 254 and the door substrate 251 can be reduced.

Further, the length measured from the reference point K of the door substrate 251 to the tip end Z4 of the protrusion 30b through the end Z2 along the inner peripheral surface of the film 254 is the length LY (inner path length: 8th length). At this time, the length LY corresponds to a length (LB + J1b) obtained by adding the length LB and the length J1b (LY = LB + J1b). That is, the length LY and the length L3 can be matched.

Thus, the shapes and dimensions of the

protrusions

30a and 30b are determined by the dimensions of the door substrate 252 and the film 255.

The protrusion 30c of the present embodiment is formed so as to protrude from one side in the circumferential direction of the door substrate 252 to the outer peripheral side (that is, the

outlet openings

21b, 21c, and 21d). The protrusion 30d is formed so as to protrude from the other circumferential side of the door substrate 252 to the outer peripheral side (that is, the

outlet openings

21b, 21c, and 21d).

Here, the shape and dimensions of the

protrusions

30c and 30d are determined by the dimensions of the door substrate 251 and the film 254 in the same manner as the

protrusions

30a and 30b. For this reason, as for the shapes and dimensions of the

protrusions

30c and 30d, the description of the dimensions of the door substrate 251 and the film 254 is omitted.

Note that the protrusion 30c corresponds to the protrusion 30a, the protrusion 30d corresponds to the protrusion 30b, the door substrate 252 corresponds to the door substrate 251, and the film 255 corresponds to the film 254.

In the present embodiment pair, the case 21 and the mode door 25 are made of a resin material having elasticity to some extent and excellent in strength.

Next, a specific operation of the mode door 25 of this embodiment will be described. 8 to 12 show the operating state of the mode door 25, respectively. 8 to 12, the cooling heat exchanger 22, the heating heat exchanger 23, and the air mix door 24 are not shown.

First, in the face mode shown in FIG. 8, the door substrate 252 closes the defroster outlet opening 21b, and the door substrate 251 closes the foot outlet opening 21d.

Thereby, the film 255 closely contacts the periphery of the defroster blowout opening 21b of the case peripheral wall 210 and the door substrate 251. For this reason, the defroster blowing opening 21b is sealed. The film 254 closely contacts the periphery of the foot outlet 21 d of the case peripheral wall 210 and the door substrate 251. For this reason, the foot outlet opening 21d is sealed.

At this time, the door opening 253 communicates with the face blowing opening 21c. For this reason, the face blowing opening part 21c opens. At this time, the cold air introduced from the bypass passage 26 through the door opening 256 and the hot air introduced from the hot air passage 26 a through the door opening 256 are mixed in the air mixing chamber 27. Then, the mixed air flows through the door opening 253 to the face blowing opening 21c.

As described above, in the face mode, the defroster blowing opening 21b is sealed and the foot blowing opening 21d is sealed.

Next, when the mode door 25 rotates (ie, displaces) clockwise, the bi-level mode shown in FIG. 9 is entered. In this bi-level mode, the door substrate 252 closes the defroster blowing opening 21b, and the door opening 253 communicates with the face blowing opening 21c and the foot blowing opening 21d.

At this time, the face blowing opening 21c and the foot blowing opening 21d are opened. For this reason, the air blown from the air mixing chamber 27 with the film 255 sealing the defroster blowout opening 21b in the same manner as the face mode described above, the face blowout opening 21c and the foot blowout opening 21d from the door opening 253. And flow.

Next, when the mode door 25 rotates clockwise, the foot mode shown in FIG. 10 is entered. In this foot mode, the door substrate 252 closes the defroster blowing opening 21b and the face blowing opening 21c, and the door opening 253 communicates with the foot blowing opening 21d.

In this case, the foot blowing opening 21d is opened, and the air blown from the air mixing chamber 27 flows from the door opening 253 to the foot blowing opening 21d.

Further, the film 255 closely adheres between the periphery of the face outlet opening 21 c in the case peripheral wall 210 and the door substrate 252, and between the periphery of the defroster outlet opening 21 b in the case peripheral wall 210 and the door substrate 251. Adhere. For this reason, the defroster blowing opening 21b and the face blowing opening 21c are sealed.

Next, when the mode door 25 rotates clockwise, the foot-diff mode is set as shown in FIG. In the foot-def mode, the film 255 seals the face blowing opening 21c, and the air blown from the air mixing chamber 27 flows from the door opening 253 to the foot blowing opening 21d. Furthermore, the air blown out from the air mixing chamber 27 flows from the door opening 256 to the defroster blowing opening 21b.

Next, when the mode door 25 rotates clockwise, the defroster mode is set as shown in FIG. In the defroster mode, the door substrate 252 closes the face blowing opening 21c and the foot blowing opening 21d. Further, the door opening 256 communicates with the defroster blowout opening 21b.

At this time, the defroster outlet opening 21b is opened, the film 255 closely contacts the periphery of the face outlet opening 21c in the case peripheral wall 210 and the door substrate 252, and the foot outlet opening in the case peripheral wall 210. The periphery of the portion 21d and the door substrate 252 are in close contact with each other. Thereby, the face blowing opening 21c and the foot blowing opening 21d are sealed. In this case, the air blown out from the air mixing chamber 27 flows from the door opening 256 to the defroster blowing opening 21b.

According to the present embodiment described above, the mode door 25 is a protrusion formed so as to protrude in the outer peripheral direction from the ends Z1 and Z2 in the circumferential direction (plate surface direction) of the door substrate 251 (252).

Part

30a, 30b (30c, 30d) is provided. The film 254 (255) extends along the outer peripheral side of the

door substrates

251 and 252 and is wound around the

protrusions

30a and 30b (30c and 30d) by elastic deformation and bent to the inner peripheral side of the door substrate 251 (252). It has been.

Here, the length in the circumferential direction measured along the outer peripheral surface of the film 254 (255) between the arbitrary reference point K and the bending start point Y1 of the door substrate 251 (252) is defined as a length L1. Then, the protrusion 30a (30c) is formed such that the length (LA + J1a) obtained by adding the length LA and the length J1a is the same as the length L1. Therefore, the distance from an arbitrary reference point K of the film 254 (255) through the end Z1 to the tip Z3 of the protrusion 30a (30c) is measured along the inner peripheral surface side of the film 254 (255). The obtained length LX (inner path length) and the length L1 (outer path length) can be matched.

Moreover, when the length in the circumferential direction measured along the outer peripheral surface of the film 254 (255) between an arbitrary reference point K and the bending start point Y2 of the door substrate 251 (252) is a length L3. The protrusion 30b (30d) is formed so that the length (LB + J1b) obtained by adding the length LB and the length J1b is the same as the length L3. Therefore, the distance from any reference point K of the film 254 (255) to the tip Z4 of the protrusion 30b (30d) via the end Z2 is measured along the inner peripheral surface of the film 254 (255). The obtained length LY (inner path length) and the length L3 (outer path length) can be matched.

As described above, it is possible to suppress the bending start points Y1 and Y2 from being displaced by the elastic force of the film 254 (255). For this reason, it can suppress that a clearance gap produces between case surrounding wall part 210 and film 254 (255). Thereby, it is possible to suppress the occurrence of a sealing failure that impairs the sealing performance of the blowing

openings

21b, 21c, and 21d due to the displacement of the bending start points Y1 and Y2 in the film 254 (255).

In the present embodiment, as described above, the bending start points Y1 and Y2 of the film 254 (255) can be suppressed from being displaced. Therefore, the bending start points Y1 and Y2 can be set at arbitrary positions depending on the shape of the protrusions 30a to 30d and the angle of the protrusions 30a to 30d. The angle of the protrusions 30a to 30d is an angle formed by the direction in which the protrusions 30a to 30d protrude with respect to the plate surface direction of the door substrate 251 (252).
