[0003] [Patent Document 1] JP 2007-245951 A Summary of the Invention [Problem to be solved by the invention]

[0004] A vehicle door provided with a speaker generally includes a door body having an inner panel and a door trim that is detachably attached to the door body. Some vehicle doors have a speaker attached to the door body and an opening (work opening) for work in the inner panel. In this type of vehicle door, for example, a speaker is attached in a form facing the vehicle interior space inside the door, and sound is emitted from the front side of the speaker toward the vehicle interior space, but sound can also be emitted from the rear side of the speaker. When sound is emitted from the rear side of the speaker in this way, there is a risk that the sound will wrap around from the rear side of the inner panel (the side opposite the vehicle interior space) to the front side (the vehicle interior space side) through the opening, or vibrate the inner panel. When sound wraps around from the rear side through the opening, for example, there is a concern that a sound of an opposite phase will have an effect of canceling out the sound emitted from the speaker to the front side, resulting in a deterioration in sound quality. Even in a configuration in which the opening is not provided, the sound emitted to the rear side may vibrate the inner panel, resulting in a deterioration in sound quality due to a similar effect.

[0005] To address this issue, a method has been used in which sound deadening material is attached directly to the inner panel so as to block the opening of the inner panel. However, with this method, once sound deadening material has been attached to the inner panel and use has begun, if it becomes necessary to remove the sound deadening material later, the work becomes very extensive. For example, if sound deadening material is attached directly to block the opening of the inner panel, the sound deadening material must be removed when the opening is to be used thereafter (for example, when performing work such as passing a hand or a part through the opening), and after using the opening, the sound deadening material must be attached again to the inner panel, which creates a problem in terms of workability.

[0006] One of the objectives of the present disclosure is to provide a technology that can realize a configuration that can prevent sound emitted from a speaker attached to the door body to the back side from affecting the vehicle interior space, while minimizing the reduction in workability. [Means for solving the problem]

[0007] The method for attaching a deadening material to a vehicle door, which is one aspect of the present disclosure, is as follows: A vehicle door includes a door body having an inner panel, a door trim that is detachably attached to the door body, and a speaker is attached to the door body, and a method for attaching a deadening material to an inside of the vehicle door includes the steps of: At least a flexible sheet having flexibility is used as the deadening material, and the flexible sheet is fixed to the door trim, thereby forming a unit in which the flexible sheet is fixed to the door trim and is detachable from the door main body; When the unit is attached to the door body, the door trim is attached to the door body while pressing the flexible sheet against the inner panel directly or indirectly via another sheet material; When removing the unit from the door body, the door trim is removed from the door body, and the flexible sheet is detached from the door body together with the door trim.

[0008] The deadening structure for a vehicle door, which is one aspect of the present disclosure, is as follows: A deadening structure for a vehicle door, the vehicle door including a door main body having an inner panel, a door trim detachably attached to the door main body, and a speaker attached to the door main body, A flexible sheet having flexibility and fixed to the door trim is provided. When the flexible sheet is fixed to the door trim, a unit formed by integrating the flexible sheet and the door trim becomes detachable from the door main body, When the unit is attached to the door body, the flexible sheet is pressed against the inner panel directly or indirectly via another sheet material, When the unit is removed from the door body, the flexible sheet comes off from the door body together with the door trim. Effect of the Invention

[0009] According to the technology disclosed herein, a configuration can be realized that can prevent sound emitted from a speaker attached to the door body to the back side from affecting the vehicle interior space, while minimizing any reduction in workability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Each of the following [1] to

[16] is an example of technology such as an object or method included in this disclosure. [1] A vehicle door is provided with a door body having an inner panel, a door trim that is detachably attached to the door body, and a speaker is attached to the door body, and a method of attaching a deadening material to the inside of the vehicle door is provided, comprising: At least a flexible sheet having flexibility is used as the deadening material, and the flexible sheet is fixed to the door trim, thereby forming a unit in which the flexible sheet is fixed to the door trim and is detachable from the door main body; When the unit is attached to the door body, the door trim is attached to the door body while pressing the flexible sheet against the inner panel directly or indirectly via another sheet material; When the unit is to be removed from the door body, the door trim is removed from the door body, and the flexible sheet is detached from the door body together with the door trim. A method for installing deadening material in a vehicle door.

[0012] In the mounting method of the above [1], the unit in which the flexible sheet is fixed to the door trim is configured to be detachable from the door body, and therefore the flexible sheet can be attached to the inner panel directly or indirectly via another sheet material by a relatively simple operation of attaching the unit to the door body. When the operation of attaching the unit is performed in this manner, the flexible sheet is firmly pressed against the inner panel, so that the inner panel can be effectively prevented from vibrating due to the sound from the back side, and the operation for creating such a suppression structure can be simplified. Furthermore, if it becomes necessary to separate the flexible sheet from the inner panel for some reason after the suppression structure is implemented, the unit can be removed from the door body. When the unit is removed in this manner, the flexible sheet is removed integrally with the door trim, so that the flexible sheet can be easily separated. If it is desired to use the suppression structure again after the flexible sheet is removed in this manner, the unit can be attached to the door body again, and the suppression structure can be created with a simple operation.

[0013] [2] The inner panel is provided with one or more openings, When the unit is attached to the door body, the door trim is attached to the door body while pressing the flexible sheet against the inner panel directly or indirectly via another sheet material so as to cover the opening area of ​​the opening and press the flexible sheet against the periphery of the opening. A method for installing deadening material in a vehicle door as described in [1].

[0014] The vehicle door targeted by the mounting method of [2] has an opening in the inner panel, so there is a risk that sound emitted from the speaker attached to the door body to the rear side may affect the vehicle interior space through the opening. In contrast, the mounting method of [2] can attach the flexible sheet so as to cover the opening area of ​​the opening formed in the inner panel and press it against the periphery of the opening by a relatively simple operation of mounting a unit in which a flexible sheet is fixed to the door trim to the door body. When the unit is mounted in this manner, the opening area of ​​the opening is blocked by the flexible sheet or by the flexible sheet and another sheet material while the flexible sheet is firmly pressed against the periphery of the opening. Therefore, it is possible to suppress sound emitted from the speaker attached to the door body to the rear side from affecting the vehicle interior space through the opening, and the operation for creating such a suppression structure can be simplified. In addition, if it becomes necessary to move the flexible sheet away from the opening for some reason after the suppression structure is implemented, the unit can be removed from the door body. When the unit is removed in this manner, the flexible sheet is removed together with the door trim, so that the flexible sheet can be easily separated from the opening. If it is desired to use the suppression structure again after the flexible sheet has been removed in this manner, the unit can be reattached to the door body, and the suppression structure can be created with a simple operation.

[0015] [3] The speaker has an annular end, a communication portion is provided on an inner wall portion of the door trim to communicate an inner space with an outer space of the door trim, the vehicle door is configured such that the door trim is disposed on one side of the speaker and a sound emitting portion of the speaker covers the communication portion, and the door trim is attached to the door body; As the deadening material, in addition to the flexible sheet, a flexible annular member is used, With the door trim detached from the door body, the annular member is attached to the one end of the annular member so as to be aligned with the one end of the annular member; When the unit is attached to the door body, the annular member is sandwiched between an inner wall portion of the door trim and one end of the annular member and compressed, and the unit is attached to the door body so that the communication portion is covered by the sound emitting portion. A method for installing a deadening material in a vehicle door according to [1] or [2].

[0016] In the mounting method of the above [3], the unit is mounted on the door body so that the sound emitting part of the speaker covers the communication part, so that after mounting, the sound emitted from the sound emitting part easily passes through the communication part and easily reaches the vehicle interior space. However, if the communication part is simply covered by the sound emitting part, the sound emitted from the sound emitting part leaks from the gap between the annular end of the speaker and the inner wall part of the door trim, and there is a concern that this phenomenon will reduce the sound quality or volume of the sound reaching the vehicle interior space. In contrast, the mounting method of the above [3] adopts a method of mounting the unit in a configuration in which an annular member is sandwiched between the inner wall part of the door trim and the annular end of the speaker while the annular member is compressed when mounting the unit on the door body. Due to this feature, the gap between the annular end of the speaker and the inner wall part of the door trim is more reliably blocked, and the deterioration of sound quality and volume caused by the sound emitted from the sound emitting part leaking from the gap can be suppressed.

[0017] [4] The vehicle door is configured such that one end side of a flexible part having at least one of an electric wire portion and a wire portion is connected to the door main body side, a slit extending from one side to the other side of the flexible sheet is provided at a predetermined position of the flexible sheet; When the unit is attached to the door body, the flexible part is placed across one side and the other side of the soft sheet so as to pass through the slit, and the unit is attached to the door body in a state where the other end side of the flexible part is connected to the door trim side. A method for mounting a deadening material on a vehicle door according to any one of [1] to [3].

[0018] The above mounting method [4] allows the flexible sheet to be attached and detached by the relatively simple operation of attaching and detaching the unit to the door body, even if the flexible part is configured such that one end is connected to the door body and the other end is connected to the door trim.

[0019] [5] A waterproof sheet is attached to the inner panel in a configuration that covers the opening, When the unit is attached to the door body, the waterproof sheet is sandwiched between the peripheral portion of the opening and the flexible sheet, and the unit is attached to the door body while pressing the flexible sheet against the waterproof sheet at a position that closes the opening area. A method for mounting a deadening material in a vehicle door according to any one of [2] to [4].

[0020] The mounting method of [5] above can prevent water from entering the door trim from the back side of the inner panel through the opening by using the waterproof sheet, while preventing sound emitted from the speaker to the back side from affecting the vehicle interior space through the opening. Furthermore, since the flexible sheet can be arranged to press against the waterproof sheet at a position that blocks the opening area of ​​the opening, it is possible to reliably prevent sound emitted to the back side from propagating to the waterproof sheet in the position that covers the opening area and causing the waterproof sheet to vibrate.

[0021] [6] When the unit is attached to the door body, the unit is attached to the door body so that the flexible sheet is in contact with the inner edge of the opening and a part of the flexible sheet is inserted into the opening. A method for mounting a deadening material in a vehicle door according to any one of [2] to [4].

[0022] The above-mentioned mounting method [6] enables the flexible sheet to be more firmly attached to the opening, and makes it easier to close the opening more reliably, thereby more reliably preventing sound that has leaked around to the back side of the inner panel from being transmitted to the vehicle interior space through the opening.

The flexible sheet 60 is flexible and is fixed to the door trim 40 so as to cover the openings 16A, 16B provided in the inner panel 12. The annular member 80 is attached to one end 38 of the speaker 30 (FIG. 8).

[0057] In the sound deadening structure 2, the flexible sheet 60 is fixed to the door trim 40, and this configuration allows a unit 8 (FIG. 4) in which the flexible sheet 60 and the door trim 40 are integrated to be detachable from the door body 10 (FIG. 2). In this configuration, when the unit 8 is attached to the door body 10, the flexible sheet 60 is indirectly pressed against the inner panel 12 via the waterproof sheet 24 (another sheet material) so as to cover the opening area of ​​the opening 16A and be pressed against the peripheral portion 18 of the opening 16A as shown in FIG. 10. When the unit 8 is removed from the door body 10, the flexible sheet 60 detaches from the door body 10 together with the door trim 40, and the flexible sheet 60 moves away from the vicinity of the opening 16A as shown in FIG. 9.

[0058] 3. How to install sound deadening materials When implementing the method for mounting the deadening material employed in the deadening structure, first, the unit 8 is prepared. Specifically, at least a flexible sheet 60 having flexibility is used as the deadening material. The flexible sheet 60 is preferably made of a material having flexibility and resilience, and may be a resin material such as urethane, or may be rubber or elastomer. For example, the flexible sheet 60 is preferably made of a structure and material having flexibility such that it deforms to match the surface shape of the contacting counterpart (the door body 10) when pressed against the door body 10, and is preferably deformed into a compressed state so that the thickness of the portion pressed from both sides becomes smaller when the unit 8 is sandwiched between the door trim 40 and the inner panel 12 and pressed from both sides. In addition, when the unit 8 is removed from the door body 10 and the state of being sandwiched between the door trim 40 and the inner panel 12 (the state of being pressed from both sides) is released, it is preferably deformed into an expanded state so that the thickness of the portion pressed from both sides becomes larger. 4, a unit 8 is formed in which the flexible sheet 60 is fixed to the door trim 40 as shown in Fig. 6, and the unit 8 is made detachable from the door body 10. In this embodiment, the unit 8 can be attached to the door body 10 by inserting an insertion portion 43 (projection portion) provided on the door trim 40 into an insertion receiving portion 13 (hole portion) provided on the door body 10, and the unit 8 can be removed from the door body 10 by removing the insertion portion 43 from the insertion receiving portion.

[0059] Furthermore, in this mounting method, a flexible annular member 80 is used as the deadening material. As shown in Fig. 7 and Fig. 8, the annular member 80 is attached to the front surface of the annular one end 38 (front end) of the speaker 30 so as to cover the annular one end 38 from the front side along the annular one end 38. Specifically, in a state in which the door trim 40 is detached from the door body 10, the annular member 80 is attached to the annular one end 38 so as to follow the annular one end 38, whereby the annular member 80 can be integrated with the door body 10.

[0060] After adopting such a configuration, the deadening material can be attached and detached by attaching and detaching the unit 8 to and from the door body 10. Specifically, by attaching the unit 8 to the door body 10, the door trim 40 is attached to the door body 10 while indirectly pressing the flexible sheet 60 against the inner panel 12 via the waterproof sheet 24 (another sheet material) so as to cover the opening area of ​​the opening 16 and press it against the peripheral part 18 of the opening 16, as shown in Fig. 10. Specifically, the waterproof sheet 24 is sandwiched between the peripheral part 18 of the opening 16 and the flexible sheet 60, and the door trim 40 is attached to the door body 10 while pressing the flexible sheet 60 against the waterproof sheet 24 at a position that blocks the opening area.

[0061] 12, the annular member 80 is sandwiched between the inner wall portion 44 and the annular one end portion 38 of the door trim 40 and is in a compressed state, and the opening area of ​​the annular member 80 is located between the sound emitting portion 32 and the communicating portion 46. Specifically, the annular member 80 is compressed while being sandwiched between the inner wall portion 44 and the annular one end portion 38 of the door trim 40, and the unit 8 is attached to the door body 10 such that the communicating portion 46 is covered by the sound emitting portion 32.

[0062] In the technology according to the present embodiment, as shown in Fig. 4, a slit 68 is provided at a predetermined position of the flexible sheet 60, which continues from one side (front side) to the other side (rear side) of the flexible sheet 60. When mounting the unit 8 to the door body 10 as described above, before mounting, the flexible part 4 is inserted so as to pass through the slit 68 as shown in Fig. 5 and straddles the one side and the other side of the flexible sheet 60, with the other end of the flexible part 4 connected to the door trim 40. After making such connections, the unit 8 is attached to the door body 10 as described above.

[0063] On the other hand, when removing the unit 8 from the door body 10, the door trim 40 is removed from the door body 10, and the flexible sheet 60 can be detached from the door body 10 together with the door trim 40, as shown in Fig. 9. When the door trim 40 is separated from the door body 10 in this manner, workers can easily access the vicinity of the opening 16, etc. In addition, when the door trim 40 is detached from the door body 10, the speaker 30 and the annular member 80 are also separated from the inner wall portion 44, as shown in Fig. 11, which allows workers to easily access the vicinity of the speaker 30.

[0064] 4.Examples of effects In the above-mentioned mounting method and sound deadening structure, the unit 8, in which the flexible sheet 60 is fixed to the door trim 40, is configured to be detachable from the door body 10, so that the flexible sheet 60 can be attached by a relatively simple operation of attaching the unit 8 to the door body 10. In this mounting method, when the unit 8 is mounted during maintenance or the like, as shown in FIG. 10, the flexible sheet 60 can be attached while indirectly pressing the flexible sheet 60 through the waterproof sheet 24 (another sheet material) so as to cover the opening area of ​​the opening 16 formed in the inner panel 12 and press it against the peripheral portion 18 of the opening 16. When the operation of mounting the unit 8 is performed in this manner, the opening area of ​​the opening 16 is blocked by the flexible sheet 60 and the waterproof sheet 24 (another sheet material) while the flexible sheet 60 is firmly pressed against the peripheral portion 18 of the opening 16. Therefore, it is possible to suppress the sound emitted from the speaker 30 attached to the door body 10 on the back side from affecting the vehicle interior space through the opening 16, and the operation for creating such a suppression structure can be simplified. Furthermore, if it becomes necessary to move the flexible sheet 60 away from the opening 16 for some reason after the restraining structure is implemented, the unit 8 can be removed from the door body 10. When the unit 8 is removed in this manner, the flexible sheet 60 is removed integrally with the door trim 40, so that the flexible sheet 60 can be easily moved away from the opening 16 as shown in Fig. 9. If it is desired to use the restraining structure again after the flexible sheet 60 has been removed in this manner, the unit 8 can be reattached to the door body 10, and the restraining structure can be implemented with a simple operation.

[0065] In the above-mentioned mounting method and sound deadening structure, the unit 8 is mounted on the door body 10 so that the sound emitting part 32 of the speaker 30 covers the communication part 46, so that after mounting, the sound emitted from the sound emitting part 32 easily passes through the communication part 46 and easily reaches the vehicle interior space. However, if the communication part 46 is simply covered by the sound emitting part 32, the sound emitted from the sound emitting part 32 leaks from the gap between the annular one end part 38 of the speaker 30 and the inner wall part 44 of the door trim 40, and there is a concern that this phenomenon will reduce the quality or volume of the sound reaching the vehicle interior space. In contrast, the above-mentioned mounting method employs a method of mounting the unit 8 on the door body 10 in such a manner that the annular member 80 is sandwiched between the inner wall part 44 of the door trim 40 and the annular one end part 38 of the speaker 30 and compressed. Due to these characteristics, the gap between the annular end 38 of the speaker 30 and the inner wall portion 44 of the door trim 40 is more reliably sealed, thereby suppressing the deterioration in sound quality and volume caused by sound emitted from the sound-emitting portion 32 leaking through the gap.

[0066] In the above-described mounting method and deadening structure, even if one end of the flexible part 4 is connected to the door body 10 and the other end is connected to the door trim 40, the flexible sheet 60 can be attached and detached by the relatively simple task of attaching and detaching the unit 8 to the door body 10.

[0067] The above-mentioned mounting method can prevent water from entering the door trim 40 side from the back side of the inner panel 12 through the opening 16 by the waterproof sheet 24, while also preventing sound emitted from the speaker 30 to the back side of the inner panel 12 from affecting the vehicle interior space through the opening 16. Furthermore, since the flexible sheet 60 can be arranged to press against the waterproof sheet 24 at a position that blocks the opening area of ​​the opening 16, it is possible to reliably prevent sound emitted to the back side of the inner panel 12 from propagating to the waterproof sheet 24 in a position that covers the opening area, causing the waterproof sheet 24 to vibrate.

[0068] In the above-described mounting method and sound deadening structure, when the unit 8 is mounted on the door body 10, as shown in Fig. 10, the unit 8 can be attached to the door body 10 so that at least a portion of the flexible sheet 60 enters the opening 16A while contacting the peripheral portion 18 (e.g., near the inner edge) of the opening 16A. With this method, the flexible sheet 60 can be more reliably brought into close contact with the opening 16, and the opening 16 can be more reliably blocked, so that sound that has been transmitted around to the rear side of the inner panel 12 can be more reliably prevented from being transmitted to the vehicle interior space via the opening 16.

[0069] 10, in the inner panel 12, a recess 14 recessed on the side opposite to the vehicle interior space is provided, an opening 16A is provided with an inner wall portion within the recess 14 that is open, and the unit 8 is attached to the door body 10 with a configuration in which a part of the flexible sheet 60 is pushed into the recess 14 to close the opening 16A within the recess 14. With this method, the opening 16A within the recess 14 can be more reliably closed in the vehicle door 1 in which the opening 16A is provided within the recess 14, and such a configuration can be realized with minimal deterioration in workability.

[0070] In the above-mentioned mounting method and deadening structure, two or more openings (e.g., openings 16A, 16B) are provided in the inner panel, one flexible sheet 60 spans the two or more openings, and a part of the flexible sheet 60 is pressed against each of the peripheries of the two or more openings spanned by the flexible sheet 60 to close each opening, and the unit 8 is attached to the door body. In this method, in a vehicle door 1 provided with two or more openings, the flexible sheet 60 is easily attached and detached to and from the door body 10, and the two or more openings can be more reliably closed.

[0071] In the above-described mounting method and sound deadening structure, the inner surface of the door trim 40 or a part held on the inner surface is adhered to the flexible sheet 60 with double-sided tape. According to this method, the flexible sheet 60 can be fixed to the door trim 40 side with a simple structure.

[0072] In the above-described mounting method and deadening structure, a waterproof layer is provided on at least the surface portion of the flexible sheet 60 facing the door body 10, which is waterproofed. The unit 8 is attached to the door body 10 so that this waterproof layer is pressed against the peripheral portion 18 of the opening 16 while covering the opening region of the opening 16. In this method, a structure that can block the opening 16 while suppressing water passage from the surface side (door body 10 side) of the flexible sheet 60 to the back side (door trim 40 side) can be realized with a configuration that allows the flexible sheet 60 to be easily attached and detached.

[0073] <Other embodiments> The present invention is not limited to the embodiments described above and in the drawings. For example, the features of the above or later described embodiments can be combined in any combination within a range that does not contradict. Furthermore, any feature of the above or later described embodiments can be omitted unless it is clearly stated as essential. Furthermore, the above described embodiments may be modified as follows.

[0074] The deadening structure and the mounting method adopted in the deadening structure are a structure and method for mounting the unit 8 so that the flexible sheet 60 covers the opening 16 provided in the inner panel 12 of the vehicle door 1, but are not limited to this structure. For example, the deadening structure or mounting method may be intended for a vehicle door having a door body without an opening provided in the inner panel (for example, a door body obtained by modifying the door body 10 configured as shown in FIG. 3 to a structure without the opening 16 (blocked structure)). For example, even in the case of a vehicle door obtained by modifying the representative vehicle door 1 to a structure without the opening 16 (blocked structure), the same flexible sheet 60 as in the first embodiment is used as the deadening material, and the flexible sheet 60 is fixed to the door trim 40 as in FIG. 4, so that the unit 8 with the flexible sheet 60 fixed to the door trim 40 can be configured to be detachable from the door body (the door body obtained by modifying the door body 10 in FIG. 3 to a structure without the opening 16 (blocked structure)). In this case, when the unit 8 is attached to the door body, the door trim 40 can be attached to the door body while pressing the flexible sheet 60 against the inner panel 12 directly or indirectly via another sheet material. Even in this configuration, when the unit 8 is attached to the door body, one side of the flexible sheet 60 is firmly pressed against the inner panel 12, so that even if sound is emitted from the speaker 30 to the back side of the inner panel 12, the sound can be prevented from vibrating the inner panel 12. On the other hand, when the unit 8 is removed from the door body, the door trim 40 can be removed from the door body together with the flexible sheet 60. Even in such a configuration, the annular member 80 can be used in the same configuration as in the first embodiment.

[0075] The above-described embodiment uses a vehicle door 1 having the configuration shown in Figure 1 as a representative example, but the above-described mounting method and deadening structure can be applied to various known vehicle doors as long as the vehicle door has a door trim, a door main body having an inner panel, an outer panel overlapping the inner panel, and a speaker, and the door trim is configured to be detachable from the door main body.

[0076] The deadening structure shown in Fig. 13 and Fig. 14 and the mounting method adopted in this structure are different from the deadening structure 2 of the first embodiment and the mounting method adopted in this deadening structure 2 only in that the waterproof sheet 24 and the adhesive 25 are not provided, and are the same as the deadening structure 2 of the first embodiment and the mounting method adopted in this deadening structure 2 except that the waterproof sheet 24 and the adhesive 25 are removed. Therefore, the example of Fig. 13 and Fig. 14 is a configuration in which the waterproof sheet 24 and the adhesive 25 are omitted in the examples of Fig. 1 to Fig. 12. In the example of Fig. 13 and Fig. 14, the configuration on the door trim 40 side is the same as the configuration on the door trim 40 side in the first embodiment, and the same unit 8 (Fig. 2) as in the first embodiment is used. In the deadening structure of the example of Fig. 13 and Fig. 14 and the mounting method adopted in this structure, the flexible sheet 60 is fixed to the door trim 40, and the unit 8 in which the flexible sheet 60 and the door trim 40 are integrated is configured. The unit 8 is detachably attached to the door body 10. In this configuration, when the unit 8 is attached to the door body 10, the flexible sheet 60 is directly pressed against the inner panel 12 so as to cover the opening area of ​​the opening 16 and to be pressed against the peripheral portion 18 of the opening 16. Specifically, when the unit 8 (FIG. 2) is attached to the door body 10, the unit 8 is attached to the door body 10 so that the flexible sheet 60 is in contact with the peripheral portion 18 of the opening 16 and a part of the flexible sheet 60 is inserted into the opening 16A as shown in FIG. 14. In this method, the flexible sheet 60 can be more reliably brought into close contact with the opening 16A and the opening 16A is more reliably blocked, so that the sound that has gone around to the back side of the inner panel 12 can be more reliably prevented from being transmitted to the vehicle interior space through the opening 16A. In addition, when such a configuration is adopted, it is more preferable that the surface portion of the flexible sheet 60 is made of the above-mentioned waterproof layer. In this way, it is possible to suppress or prevent water from entering the door trim side through the opening 16A.

[0077] In either the configuration shown in FIG. 9 or the configuration shown in FIG. 13, as long as flexible sheet 60 is pressed against peripheral portion 18 of opening 16A, flexible sheet 60 does not need to enter opening 16A.

[0078] In both the configuration shown in Fig. 9 and the configuration shown in Fig. 13, the position where the flexible sheet 60 is pressed in the peripheral portion around the opening 16A may be a peripheral portion near the opening region of the opening 16A, or may be a peripheral portion slightly distant from the opening region of the opening 16A. In the configurations shown in Fig. 9 and Fig. 13, when the door trim 40 is attached to the door body 10, the flexible sheet 60 is pressed against the peripheral portion of the opening 16A in the recess 14, but the flexible sheet 60 may be pressed near the inner edge of the hole of the recess 14, and a part or the whole of the inside of the recess 14 may not be pressed against the flexible sheet 60. In either case, it is desirable that when the door trim 40 is attached to the door body 10, the flexible sheet 60 is pressed over the entire circumference of the recess 14 in the peripheral portion of the recess 14.

[0079] It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is not limited to the embodiments disclosed herein, and is intended to include all modifications within the scope indicated by the claims or within the scope equivalent to the claims.
