The inner panel 21 constitutes the inner wall of the passenger compartment. Further, the inner panel 21 has water drain holes 22 at three locations, the front, the center, and the rear, in the vicinity of the joint at the lower edge. The inner panel 21 has an access hole 23 in the vicinity of the central drain hole (the central drain hole 22).
On the inner panel 21, a sound insulation cover 41 is disposed on the surface on the vehicle interior side so as to surround the drain hole 22 (see FIG. 2). In addition, the inner panel 21 overlaps the sound insulation cover 41 from the vehicle interior side, and on the inner surface 21a (the plate surface facing the vehicle interior side) of the inner panel 21 via an inner assembly means (not shown). An inner garnish 51 is detachably installed. As will be described later, the sound insulation cover 41 is installed integrally with the inner garnish 51. However, in FIG. 2, for the convenience of explanation, the sound insulation cover 41 remains on the inner panel 21 and the inner garnish 51 is removed. Shows the state.

The drain hole 22 is a through-hole penetrating the inner panel 21 and communicates the accommodation chamber AR1 with the interior side of the intermediate chamber AR2 described later. Then, the water due to rain or snow that has entered the accommodation room AR1 is discharged from the accommodation room AR1 through the drain hole 22 through the door glass that moves up and down.
The access hole 23 is a through hole that penetrates the inner panel 21. The access hole 23 is set to have a hole shape that allows the screw 32c of the screw fixing means 32 to be attached and detached (contactable) with a tool (not shown) such as a screwdriver.

The sound insulation cover 41 is set in each drain hole 22. That is, the sound insulation cover 41 includes a front cover 41F surrounding the periphery of the front drain hole 22, a center cover 41M surrounding the periphery of the central drain hole 22, and a rear cover 41R surrounding the periphery of the rear drain hole 22. (See FIG. 2).
As shown in FIGS. 6 to 13, each of the sound insulation covers 41 surrounds the upper, front, and rear sides except for the lower part around the drain hole 22, and stands up toward the inner panel 21 from the vehicle interior side. A sound insulating wall 42 is provided, and a turning wall 43 that obliquely intersects the extension of the drain hole 22 on the vehicle interior side. That is, the sound insulation cover 41 is formed in a U-shaped cross section by the direction change wall 43 and the sound insulation wall 42 erected from the periphery of the direction change wall 43. A groove portion on the U-shaped inner side of the sound insulating cover 41 is set as a drainage channel 44 that changes the flow direction along the penetration direction of the water drain hole 22.

As shown in FIG. 4, the drainage channel 44 is formed such that a drainage channel inlet 44 a serving as an inlet faces the drainage hole 22, and a drainage channel outlet 44 b serving as an outlet is positioned below the drainage hole 22. However, it is formed facing downward. That is, the drainage channel inlet 44 a is configured by a portion surrounding the drain hole 22 at the inner panel 21 side edge of the front wall, the upper wall, and the rear wall of the sound insulation wall 42. The drainage channel outlet 44b is located below the lower ends of the inner panel 21 and the outer panel 11, and is configured by a portion surrounded by the inner panel 21 side edge of the front wall, the lower wall, and the rear wall of the sound insulating wall 42. Has been.
The sound insulation cover 41 is formed as a separate part from the inner garnish 51 and is installed integrally with the inner garnish 51 via a joining means such as a double-sided tape or an adhesive.

The sound insulation wall 42 is set so that the size and shape in the vertical direction are blocked between the drain hole 22 and a drain hole 52 described later. That is, the sound insulation wall 42 forms a labyrinth structure between the drain hole 22 and the drain hole 52 (see FIG. 3). In addition, the size of the sound insulation wall 42 is set so that the sound insulation wall 42 is separated from the inner panel 21 with a predetermined interval. That is, the inner panel 21 side edge of the sound insulating wall 42 is formed so as to trace the surface of the inner panel 21 with a predetermined interval.
The diverting wall 43 is set in size and shape so as to overlap the entire drain hole 22 when the drain hole 22 is viewed from the front. In the turning wall 43, slits 45 are opened along the vehicle vertical direction at the front edge and the rear edge. Further, the turning wall 43 is provided with a double-sided tape 61 between the pair of slits 45, and is attached to the outer side surface 51 a of the inner garnish 51 via the double-sided tape 61. For this reason, the turning wall 43 is formed following the shape of the outer side surface 51 a of the inner garnish 51. The turning walls 43 of the front cover 41F and the center cover 41M are formed with a smooth curved surface similar to the shape of the inner surface 51b of the inner garnish 51, but the turning walls 43 of the rear cover 41R are uneven.

The dimension of the slit 45 is set such that a rib (not shown) protruding from the outer surface 51a of the inner garnish 51 can be inserted. The slit 45 is provided with a rib (not shown) so that the position of the inner garnish 51 on the vehicle outer surface 51a is defined.

As shown in FIGS. 6 to 9, the central cover 41 </ b> M is integrally provided with an access frame portion 46.
The access frame portion 46 surrounds the periphery of the access hole 23, and the central through hole 46 a communicates with the access hole 23. The access frame portion 46 has a rectangular frame shape including a frame side 47 that surrounds the upper, lower, front, and rear sides of the access hole 23.
Each frame side 47 includes a reinforcing wall 43a and a frame wall 47a and has a substantially L-shaped cross section.
The reinforcing wall 43a is obtained by extending the turning wall 43 forward of the vehicle.
The frame wall 47a is configured by a standing wall that stands from the vehicle interior side toward the inner panel 21.

The upper, front, and rear three frame walls 47a are arranged close to the access hole 23, and the lower frame wall 47b is set at a position farther from the access hole 23 than the remaining three frame walls 47a.
By separating the lower frame wall 47a from the access hole 23, the area of the reinforcing wall 43a is expanded, and the area for installing the double-sided tape 61 can be expanded. Further, since the installation area of the double-sided tape 61 is increased, the access frame portion 46 can be more firmly installed on the inner garnish 51. This prevents the access frame 46 from flapping when the vehicle vibrates.
Further, by forming the access frame portion 46 integrally with the center cover 41M, the work of assembling the access frame portion 46 to the inner garnish 51 is simplified.

The inner garnish 51 is formed together with the outer garnish 12 by injection molding of a resin material, and is integrally connected to the outer garnish 12 below the outer panel 11. That is, the inner garnish 51 and the outer garnish 12 are composed of one part through the hinge portion 55 set to a thickness that can be folded back. The intermediate chamber AR2 is formed by the space between the outer garnish 12 and the outer panel 11 and the space between the inner garnish 51 and the inner panel 21 (see FIG. 4).
Further, in the inner garnish 51, a drain hole 52 is opened at a site below the drain hole 22, and a maintenance hole 53 is opened at a site facing the access hole 23.

As shown in FIGS. 3 and 4, the drain hole 52 is a through hole that penetrates the inner garnish 51, and communicates the intermediate chamber AR <b> 2 with the outside of the vehicle.
Further, the drainage hole 52 constitutes an engagement structure 71 set at a portion of the inner garnish 51 that is offset in the vehicle front-rear direction from a position vertically below the drainage hole 22.
The engagement structure 71 locks the inner garnish 51 to the outer garnish 12, and includes a claw arm portion 72 and a claw receiving base 73.
The claw arm portion 72 is erected so as to cut and raise the bottom of the inner garnish 51, and a claw 74 is formed at the tip. A hole portion of the inner garnish 51 from which the claw arm portion 72 is cut and raised is set as a drain hole 52. The claw arm 72 has flexibility and is inserted into the engagement hole 75 of the claw receiving base 73 while being bent and deformed, and the claw 74 engages with the engagement hole 75 in the removal direction.

That is, the claw arm portion 72 is formed so as to cover the drain hole 52. For this reason, the sound insulation effect similar to the sound insulation cover 41 with respect to the drain hole 22 of this embodiment is obtained by the claw arm portion 72 with respect to the drain hole 52.
Moreover, even if the hinge part 55 is damaged by providing the engagement structure 71, the separation between the outer garnish 12 and the inner garnish 51 is suppressed.
Then, the water that has entered the intermediate chamber AR <b> 2 through the drain hole 22 is discharged outside the vehicle through the drain hole 52. That is, when water such as rain or snow enters the storage room AR1 through the door glass that can be moved up and down, it is discharged from the storage room AR1 to the intermediate room AR2 through the drain hole 22. Then, the water that has entered the intermediate chamber AR2 is discharged outside the vehicle through the drain hole 52.

  As shown in FIG. 5, the maintenance hole 53 includes a through hole that penetrates the inner garnish 51 and is closed by a removable cap 54. The position and hole shape of the maintenance hole 53 are set so that the maintenance hole 53 can contact the screw fixing means 32 (outer assembling means 13) and can communicate with the access hole 23. That is, the maintenance hole 53 has a hole shape in which the screw 32c of the screw fixing means 32 (outer assembling means 13) can be attached / detached (contactable) with a tool (not shown) such as a driver, like the access hole 23. Is set to

  The inner assembling means (not shown) has the same configuration as the above-described clip fixing means 31 (outer assembling means 13), and thus the description thereof is omitted.

Next, the effect of the vehicle door 1 according to the present embodiment will be described.
By providing a sound insulation cover 41 that includes a turning wall 43 that obliquely intersects with the extension of the drainage hole 22 inside the vehicle while surrounding at least a part of the periphery of the drainage hole 22, the penetration of the drainage hole 22 is achieved. A drainage channel 44 that changes the direction of the flow along the direction is formed on the inner side of the inner panel 21 with respect to the vehicle interior. As a result, the noise radiated through the water drain hole 22 is reflected by the sound insulation cover 41, so that the noise is suppressed from reaching the vehicle interior directly. Therefore, the vehicle door 1 can enhance the sound insulation while providing drainage.

  The noise radiated to the vehicle interior side through the drain hole 22 is reflected downward by the sound insulation cover 41. Thereby, since the noise radiated through the drain hole 22 is suppressed from reaching the vehicle interior directly, the sound insulation can be improved.

  Since the inner garnish 51 is installed on the inner surface of the inner panel 21 while overlapping the sound insulation cover 41 from the vehicle interior side, it is further suppressed that the noise radiated through the drain hole 22 reaches the vehicle interior directly. Is done. As a result, the sound insulation can be further enhanced while the drainage is maintained.

When the outer garnish 12 is detachably installed on the outer surface of the outer panel 11 via the outer assembling means 13, the inner garnish 51 penetrates the outer assembling means 13 and can be communicated with the access hole 23. The maintenance hole 53 is provided, and the maintenance hole 53 is closed with a cap 54. Accordingly, the outer garnish 12 can be installed while providing drainage and sound insulation.
Moreover, by enclosing the periphery of the access hole 23 with the access frame part 46, the spread of the sound to the space between the inner panel 21 and the inner garnish 51 is suppressed, and sound insulation can be improved.

  By connecting the outer garnish 12 and the inner garnish 51 integrally, the rigidity of the outer garnish 12 and the inner garnish 51 is increased. As a result, the generation of noise due to the vibration of the outer garnish 12 and the inner garnish 51 can be suppressed. Further, by providing the drainage hole 52 in the inner garnish 51, the drainage performance is not impaired. From the above, it is possible to further improve sound insulation without impairing drainage.

  The sound insulation wall 42 of the sound insulation cover 41 is erected toward the inner panel 21 so as to block between the drain hole 22 and the drain hole 52, so that the labyrinth structure is provided between the drain hole 22 and the drain hole 52. Is formed. As a result, noise does not enter the interior of the intermediate chamber AR2 linearly, so that sound insulation can be improved.

  By forming the sound insulating cover 41 and the inner garnish 51 as separate parts, the sound insulating cover 41 and the inner garnish 51 are not impaired as compared with the case where the sound insulating cover 41 and the inner garnish 51 are formed as one part. Can be formed into a more suitable shape.

  When the sound insulation cover 41 is fixed to both the inner garnish 51 and the inner panel 21, if the dimensional accuracy is low, the sound insulation cover 41 is rattled due to vibration, causing noise. For this reason, it is necessary to increase the molding accuracy, resulting in an increase in manufacturing cost. However, since the shape is set so that the sound insulating cover 41 is separated from the inner panel 21, the generation of noise due to vibration can be suppressed without increasing the molding accuracy. Therefore, it is possible to improve the sound insulation while suppressing the manufacturing cost.

In addition, although the sound-insulation cover 41 of this embodiment is provided with a U-shaped cross section and the drainage channel 44 is formed in a groove shape, it is not limited to such a shape. For example, an elbow pipe (not shown) in which a circular pipe is bent can be used instead of the sound insulation cover, and the same effect as the present embodiment can be obtained. Moreover, it is also possible to set it as the structure which installs the sound insulation cover 41 in the inner panel 21 while separating the sound insulation cover 41 from the inner garnish 21, and the effect similar to this embodiment is acquired.
The flow may be changed upward and water may be accumulated in the drainage channel 44 in the sound insulation cover 41 so as to close the drain hole 22. Since the drain hole 22 is blocked, the sound insulation on a rainy day can be further enhanced.

The sound insulation cover 41 of this embodiment is set so that the sound insulation wall 42 is spaced from the inner panel 21 while being fixed to the inner garnish 51, but is not limited to such a shape. For example, the sound insulation cover 41 may be fixed to the inner panel 21 while being spaced apart from the inner garnish 51 by a predetermined distance, and the same effects as the present embodiment can be obtained.
When the outer garnish 12 is installed and the inner garnish 51 is not installed, the cap 54 is installed on the access frame portion 46 while the sound insulation cover 41 is installed on the inner panel 21 and the access hole 23 is closed. In other words, the same effects as the present embodiment can be obtained.

Although the drainage hole 52 of this embodiment is opened in the site | part of the inner garnish 51 located below the drainage hole 22, it is not a thing limited to such a structure. For example, it is good also as a structure opened in the location which is not conspicuous from the outside in the site | part of the outer garnish 12 located below the drain hole 22, and the same effect is obtained.
The diverting wall 43 of the present embodiment is sized and shaped so as to overlap the entire drainage hole 22 when the drainage hole 22 is viewed from the front, but is not limited to such a configuration. Absent. For example, the shape of the turning wall 43 may be set so as to overlap a part of the drain hole 22 when the drain hole 22 is viewed from the front.
