Description

[Technical Field]

[0001] The present invention relates to a door for a vehicle. [Background technology]

[0002] A vehicle door has an outer panel on the vehicle exterior side and an inner panel on the vehicle interior side. Of these panels, the outer panel is particularly prone to contact with people and objects. For this reason, a panel reinforcement is attached to the inside of the outer panel to prevent the outer panel from easily deforming (see Patent Document 1).

[0003] On the other hand, when designing a vehicle, it is important to lower the frequency of the sound generated when the door is closed to give the vehicle a sense of weight and, as a result, a sense of luxury. However, if the panel rain located on the inside of the outer panel is fixed at intervals with adhesive, the rigidity of the outer panel increases but its natural frequency also increases, which causes the sound when the door is closed to shift to a higher frequency, losing the sense of luxury.

[0004] [Patent Document 1] Patent Publication No. 2021-45995 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, an object of the present invention is to provide a vehicle door having an outer panel reinforced with panel reinforcement, which is configured to generate predominantly low-frequency sounds when the door is closed. [Means for solving the problem]

[0006] In order to achieve this object, the present invention is characterized by the following configuration.

[0007] First, the present invention provides a vehicle door having an outer panel that is attached to a vehicle body by a front hinge so as to be able to open and close, and a panel rain that extends in the fore-and-aft direction of the vehicle inside the outer panel, the outer panel and the panel rain being fixed together by a plurality of adhesive portions, The outer panel is a first band-shaped protrusion that protrudes toward the vehicle exterior and extends in the vehicle front-rear direction; a band-shaped recessed portion that is located below the first band-shaped protrusion and that protrudes toward the passenger compartment and extends in the front-rear direction of the vehicle; a second band-shaped protrusion that is located below the band-shaped recess and protrudes toward the vehicle exterior and extends in the vehicle front-rear direction, The band-shaped recess is a recessed apex line extending in the front-rear direction and projecting most toward the passenger compartment side between the upper end and the lower end of the band-shaped recess, The outer panel is an upper region located above the recessed ridge line; a lower region located below the recessed ridge line, the number of adhesive portions in the upper region is greater than the number of adhesive portions in the lower region; the lower region is divided into a front lower region close to the front hinge and a rear lower region distant from the front hinge by a vertical line passing through the center of gravity of the outer panel, The aforementioned The number of adhesive bonds in the front lower region is The aforementioned greater than the number of adhesive bonds in the rear lower region; It is characterized by:

[0008] According to the present invention, the number of adhesive portions in the upper region located above the apex line of the band-shaped recess of the outer panel is greater than the number of adhesive portions in the lower region located below the apex line of the band-shaped recess of the outer panel. Furthermore, the number of adhesive portions in the front lower region in the lower region, which is close to the front hinge, is greater than the number of adhesive portions in the rear lower region in the lower region, which is farther from the front hinge. Because the number of adhesive portions in the upper region is greater than the number of adhesive portions in the lower region, the rigidity of the upper region is greater than the rigidity of the lower region. Therefore, when an occupant touches the upper region of the outer panel to open or close the door, the upper region has a sufficiently high rigidity to prevent it from easily bending due to an external force. Furthermore, because the number of adhesive portions in the front lower region is greater than the number of adhesive portions in the rear lower region, the rigidity of the rear lower region is less than that of the front lower region. This rear lower region is the region where door closing noise occurs when an occupant closes the door, and because it has a sufficiently low rigidity, the natural frequency is low. Therefore, when an occupant closes the door, a low frequency sound, i.e., a heavy door slamming sound, may be generated.

[0009] A plurality of the adhesive portions may be present on the recessed apex line.

[0010] According to this configuration, the presence of a plurality of adhesive portions on the recess apex line ensures sufficient rigidity of the band-shaped recess.

[0011] In addition, the first band-shaped protrusion is a convex apex line that is located between an upper end and a lower end of the first band-shaped convex portion and that protrudes most toward the vehicle exterior and extends in the front-rear direction; The number of the adhesive portions between the concave ridge line and the convex ridge line may be in the range of 70% to 90% of the number of adhesive portions that bond the outer panel and the panel reinforcement.

[0012] According to this configuration, the number of adhesive joints between the concave apex line and the convex apex line is in the range of 70% to 90% of the number of adhesive joints bonding the outer panel and the panel rain, thereby sufficiently stiffening the area between the first band-shaped convex portion and the band-shaped concave portion, which is prone to low rigidity.

[0013] The panel rein may be present in a shape that widens from the front end to the rear end of the outer panel.

[0014] According to this configuration, the panel reinforcement is present in a shape that widens from the front end to the rear end of the outer panel, so that the rigidity of the outer panel is maintained sufficiently to prevent it from easily being deflected by an external force.

[0015] In addition, the panel rain is a first panel rain portion extending from the front end toward the rear end of the outer panel; a second panel rein portion disposed below the first panel rein portion and extending from the front end to the rear end of the outer panel, the first panel rein portion is fixed to the outer panel only by the adhesive portion disposed in the upper region, The second panel rein portion may be fixed to the outer panel by the adhesive portion disposed in the upper region and the lower region.

[0016] According to this configuration, the panel rain has a first panel rain portion extending from the front end to the rear end of the outer panel, and a second panel rain portion positioned below the first panel rain portion and extending from the front end to the rear end of the outer panel, thereby maintaining sufficient rigidity of the outer panel to prevent it from easily deforming due to external forces even when the vehicle is subjected to a side collision.

[0017] The first panel rain portion is disposed at a downward gradient from the front end to the rear end of the outer panel, The second panel rain portion is disposed at a downward gradient from the front end to the rear end of the outer panel, The downward gradient of the second panel rain portion may be greater than the downward gradient of the first panel rain portion.

[0018] With this configuration, the downward gradient of the second panel reinforcement portion is greater than that of the first panel reinforcement portion, so that the area in the rear lower region of the outer panel where the first and second panel reinforcement portions are not fixed is sufficiently large. Therefore, the rear lower region has a sufficiently low rigidity, which reduces the natural frequency and makes it easier for a heavy door closing sound to be generated.

[0019] The second band-shaped protrusion may have a length in the up-down direction that increases toward the rear of the vehicle.

[0020] According to this configuration, the vertical length of the second band-shaped protrusion increases as it moves toward the rear of the vehicle, and the area between the band-shaped recess and the second band-shaped protrusion, which has low rigidity, becomes larger as it moves toward the rear of the vehicle, resulting in a lower natural frequency and making it more likely that a heavy door closing sound will be generated.

[0021] The adhesive portion may be disposed only on the first band-shaped convex portion and the band-shaped concave portion.

[0022] According to this configuration, since the adhesive portions are provided only on the first band-shaped protrusion and the band-shaped recess, the second band-shaped protrusion has a sufficiently low rigidity, which reduces the natural frequency of the second band-shaped protrusion and makes it more likely to produce a heavy door closing sound.

[0023] The present invention also provides a vehicle door having an outer panel that is attached to a vehicle body by a front hinge so as to be able to open and close, and a panel rain that extends in the fore-and-aft direction of the vehicle inside the outer panel, the outer panel and the panel rain being fixed together by a plurality of adhesive portions, The outer panel is When the outer panel is viewed from the vehicle exterior, the outer panel is defined by a horizontal line and a vertical line passing through the center of gravity of the outer panel, a first quadrant located above the horizontal line and in front of the vertical line; a second quadrant located above the horizontal line and behind the vertical line; a third quadrant located below the horizontal line and behind the vertical line; a fourth quadrant located below the horizontal line and forward of the vertical line, The number of adhesive portions in the first quadrant and the second quadrant is greater than the number of adhesive portions in the third quadrant and the fourth quadrant, respectively. Ku, The number of adhesive portions in the fourth quadrant is greater than the number of adhesive portions in the third quadrant. It is characterized by:

[0024] According to the present invention, when the outer panel is viewed from the vehicle exterior, the number of adhesive portions in the first and second quadrants located above a horizontal line passing through the center of gravity of the outer panel is greater than the number of adhesive portions in the third and fourth quadrants located below the horizontal line. Because the number of adhesive portions in the first and second quadrants is greater than the number of adhesive portions in the third and fourth quadrants, the rigidity in the first and second quadrants is greater than the rigidity in the third and fourth quadrants. Therefore, when an occupant touches the first or second quadrant of the outer panel to open or close the door, the rigidity in the first and second quadrants is sufficiently high to prevent easy deflection due to external forces. Furthermore, the third and fourth quadrants of the outer panel have lower rigidity than the first and second quadrants, resulting in a lower natural frequency. Therefore, when an occupant closes the door, a heavy door closing sound may be generated in the third and fourth quadrants. Furthermore, with this configuration, the number of adhesive portions in the fourth quadrant is greater than the number of adhesive portions in the third quadrant, so the rigidity in the third quadrant is smaller than the rigidity in the fourth quadrant. This third quadrant is the region where door closing noise occurs when a passenger closes the door, and because the third quadrant has sufficiently small rigidity, the natural frequency is low. Therefore, when a passenger closes the door, a heavy door closing noise may occur in the third quadrant.

[0027] In addition, the panel rain is a first panel rain portion extending from the front end toward the rear end of the outer panel; a second panel rein portion disposed below the first panel rein portion and extending from the front end to the rear end of the outer panel, the first panel rein portion is fixed to the outer panel only by the adhesive portions arranged in the first quadrant and the second quadrant, The second panel rain portion may be fixed to the outer panel only by the adhesive portions arranged in the first quadrant and the fourth quadrant, or only by the adhesive portions arranged in the first quadrant, the fourth quadrant, and the third quadrant.

[0028] According to this configuration, the panel rain has a first panel rain portion extending from the front end to the rear end of the outer panel, and a second panel rain portion positioned below the first panel rain portion and extending from the front end to the rear end of the outer panel, thereby maintaining sufficient rigidity of the outer panel to prevent it from easily deforming due to external forces even when the vehicle is subjected to a side collision. [Effects of the Invention]

[0029] Therefore, the vehicle door according to the present invention is a vehicle door having an outer panel reinforced with a panel reinforcement, and is configured to generate predominantly low-frequency sounds when the door is closed. [Brief explanation of the drawings]

[Figure 8] FIG. 10 is a front view of a door with a part of an outer panel removed according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0031] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0032] [First embodiment] FIG. 1 shows a vehicle door 100 according to the first embodiment, particularly a front door located near the driver's seat or passenger seat on the front side of the vehicle, which is visible on the right side when the vehicle is viewed from the rear to the front.

[0033] The door 100 is connected to a vehicle body (not shown) so as to be able to open and close around a vertical axis 12, and has an approximately rectangular outer panel 20 that is attached to the vehicle body so as to be able to open and close by a front hinge 10, a window frame 22 connected to the top of the outer panel 20, and a garnish mounting portion 24 connected to the bottom of the outer panel 20.

[0034] The outer panel 20 is made by processing a steel plate having a thickness of 0.6 to 0.7 mm, or an aluminum or plastic plate having a similar strength, and is given a streamlined shape that flows from the front to the rear of the vehicle from the design viewpoint of giving the vehicle body a dynamic shape and the technical viewpoint of reducing the air resistance of the vehicle body. Specifically, the vehicle door 100 of the embodiment has three curved surfaces, namely, an upper first band-shaped protrusion 202 that protrudes outward from the vehicle and extends in the longitudinal direction of the vehicle, a middle band-shaped recessed portion 204 that is provided adjacent to and below the first band-shaped protrusion 202, is recessed toward the passenger compartment, and extends in the longitudinal direction of the vehicle, and a lower second band-shaped protrusion 206 that is provided adjacent to and below the band-shaped recessed portion 204, protrudes outward from the vehicle and extends in the longitudinal direction of the vehicle.

[0035] 2 to 5 are cross-sectional views of the outer panel taken along lines II-II, III-III, IV-IV, and VV in FIG.

[0036] Returning to Figure 1, the boundary between the first band-shaped convex portion 202 and the band-shaped concave portion 204 (i.e., the line connecting the inflection points where the curve changes from a convex curved surface to a concave curved surface) is shown as a first inflection curve 208, and the boundary between the band-shaped concave portion 204 and the second band-shaped convex portion 206 (the line connecting the inflection points where the curve changes from a concave curved surface to a convex curved surface) is shown as a second inflection curve 210.

[0037] As shown in the figure, the line indicating the upper edge of the first band-shaped protrusion 202 in the upper row extends in a substantially horizontal direction, and the line indicating the lower edge of the first band-shaped protrusion 202 (which is also the line indicating the upper edge of the band-shaped recess 204) extends so as to gradually become higher as it progresses from the front to the rear (from the right side to the left side in the figure). The line indicating the lower edge of the second band-shaped protrusion 206 in the lower row extends in a substantially horizontal direction, and the line indicating the upper edge of the second band-shaped protrusion 206 (which is also the line indicating the lower edge of the band-shaped recess 204) extends so as to gradually become higher as it progresses from the front to the rear. Both the lines indicating the upper and lower edges of the band-shaped recess 204 in the middle row extend so as to gradually become higher as it progresses from the front to the rear. Therefore, the convex apex line 212 connecting the points of the first band-shaped convex portion 202 that protrude most toward the outside of the vehicle in each longitudinal cross section, and the concave apex line 214 connecting the points of the band-shaped concave portion 204 that are recessed toward the inside of the vehicle in each longitudinal cross section, also extend so as to gradually become higher as they move from the front to the rear.

[0038] Although not shown, the outer surfaces of the front and rear doors of the vehicle adjacent to door 100 are formed with concave and convex curved surfaces that are continuous with the concave and convex curved surfaces of door 100, and together they create a dynamic, streamlined appearance for the vehicle's exterior.

[0039] In the illustrated embodiment, the front end of the second band-shaped protrusion 206 is located approximately halfway between the front and rear ends of the front door 2, and the second band-shaped protrusion 206 appears as an approximately triangular area (second band-shaped protrusion 206) extending rearward from that midpoint, but it may also start from the front end of the second band-shaped protrusion 206, similar to the first band-shaped protrusion 202 and band-shaped recess 204.

[0040] Fig. 6 shows the door 100 from the outside of the vehicle, with the outer panel 20 partially removed. As shown in the figure, an inner panel 30 is disposed on the passenger compartment side of the outer panel 20. Like the outer panel 20, the inner panel 30 is made of a metal plate such as iron or aluminum, or a plastic plate.

[0041] Between the outer panel 20 and the inner panel 30, a panel reinforcing panel 40 that reinforces the outer panel 20 is arranged along the inner surface of the outer panel 20, widening from the front end to the rear end of the outer panel 20 (from the right to the left in the figure) (i.e., so that the height from top to bottom gradually increases).

[0042] In this embodiment, the panel rain 40 is generally composed of an upper first panel rain portion 42 and a lower second panel rain portion 44.

[0043] Like the outer panel 20, the first panel rein portion 42 and the second panel rein portion 44 are each made of a metal plate such as iron or aluminum, or a plastic plate.

[0044] In the first embodiment, the first panel rain portion 42 and the second panel rain portion 44 are each arranged with a downward slope from the front end toward the rear end of the outer panel 20. The downward slope of the second panel rain portion 44 is set to be greater than the downward slope of the first panel rain portion 42. Therefore, the area surrounded by the first panel rain portion 42 and the second panel rain portion 44 expands toward the rear end.

[0045] The first panel rein portion 42 and the second panel rein portion 44 are each bonded and fixed to the outer panel 20 by a plurality of adhesive portions 50. The adhesive for the adhesive portions 50 may be, for example, an epoxy adhesive or an adhesive made from synthetic rubber. Each adhesive portion 50 is generally circular and has a diameter of approximately 30 mm.

[0046] As shown in the figure, Figure 6 also shows the first band-shaped convex portion 202, the band-shaped concave portion 204, the second band-shaped convex portion 206, the convex apex line 212, and the concave apex line 214 shown in Figure 1, so that the positional relationship between the areas described with reference to Figure 1 and the panel rain portions 42, 44 and adhesive portion 50 can be understood.

[0047] As is clear from this figure, the front end of the upper first panel rein portion 42 is fixed to the outer panel 20 near the front middle of the first band-shaped protrusion 202, and its rear end is fixed to the outer panel 20 near the rear middle of the band-shaped recess 204. In this embodiment, the first panel rein portion 42 is thick (large in vertical width) in the middle portion between the front and rear ends, and gradually becomes thinner (smaller in vertical width) from there toward the front and rear ends, and is arranged so as to diagonally cross the first inflection curve 208, which is the boundary between the first band-shaped protrusion 202 and the band-shaped recess 204, from front to rear.

[0048] The second panel rain portion 44 has its front end fixed to the outer panel 20 near the front lower part of the first band-shaped protrusion 202, and its rear end fixed to the outer panel 20 below the second band-shaped protrusion 206 near the midpoint in the fore-and-aft direction.

[0049] Most of the adhesive joints 50 to the first panel rein portion 42 are located between the vicinity of the convex apex line 212 of the first band-shaped convex portion 202 and the concave apex line 214 of the band-shaped concave portion 204, and are arranged along the first inflection line 208, which is the boundary between the first band-shaped convex portion 202 and the band-shaped concave portion 204, or above and below the first inflection line 208. In particular, some of the adhesive joints 50 to the first panel rein portion 42 are located on or near the first inflection line 208, and the outer panel 20 is strongly reinforced by the first panel rein portion 42 at these positions.

[0050] The door handle 222 used to open and close the door 100 is located near the rear end of the door 100, near the first inflection point 208. Therefore, the area near the first inflection point 208 is an area that is likely to be frequently touched by occupants when opening and closing the door. The area near the first inflection point 208 is also an area that is susceptible to external impacts, and since it is an area with zero curvature, it is a weak area against deformation. For this reason, as described above, many adhesive joints 50 are arranged near the first inflection point 208, and the outer panel 20 at that position is integrated with the first panel reinforcement portion 42 and reinforced.

[0051] On the other hand, most of the adhesive portion 50 of the second panel reinforcement portion 44 is disposed in the region of the band-shaped recess 204 and is not present in the second band-shaped protrusion 206 .

[0052] With respect to the number of adhesive bonds 50, in the embodiment, the number of adhesive bonds 50 for the first panel rein portion 42 is greater than the number of adhesive bonds 50 for the second panel rein portion 44. For example, in the embodiment, nine adhesive bonds 50 are provided for the first panel rein portion 42 and four adhesive bonds are provided for the second panel rein portion 44.

[0053] As described above, in the door 100 of this embodiment, the portion of the outer panel 20 near the first curved line 208, which is most likely to receive external force, is reinforced by being integrated with the first panel reinforcement portion 42 via the adhesive portion 50. Therefore, deformation of the outer panel 20 in this portion is reliably prevented.

[0054] Furthermore, in the door 100 of this embodiment, more adhesive portions 50 are provided in the upper region 216, which is located above the ridge line 214 of the band-shaped recess 204 of the outer panel 20, than in the lower region 218, which is located below the ridge line 214. For example, there are 11 adhesive portions 50 in the upper region 216 and 2 adhesive portions 50 in the lower region 218. Therefore, compared to the lower region 218, the upper region 216 provides a greater integration between the outer panel 20 and the panel reinforcement 40 that supports it.

[0055] Furthermore, a front lower region 224 (see FIG. 6) in the lower region 218 that is close to the front hinge 10 has more adhesive portions 50 than a rear lower region 226 (see FIG. 6) that is farther from the front hinge 10. For example, two adhesive portions 50 are arranged in the front lower region 224, and no adhesive portions 50 are arranged in the rear lower region 226. Therefore, compared to the rear lower region 226, the front lower region 224 provides a better integration between the outer panel 20 portion and the panel rein 40 that supports it.

[0056] As a result, the rigidity of the upper region 216 of the outer panel 20 is greater than the rigidity of the lower region 218, so that even if an occupant touches the upper region 216 of the outer panel 20 hard or if an external impact acts thereon, the outer panel 20 is not easily deformed.

[0057] Furthermore, since the rigidity of the lower region 218 is smaller than that of the upper region 216, when the door 100 is closed, the lower region 218 emits a luxurious, low-frequency sound.

[0058] In particular, the number of adhesive portions 50 in the rear lower region 226 is smaller than the number of adhesive portions 50 in the front lower region 224. This causes the rear lower region 226 to emit the lowest frequency sound and the most profound sound.

[0059] FIG. 7 shows the distribution of vibration power generated in the outer panel 20 when the door 100 of the above-described embodiment is closed, with the darker the color, the greater the power.

[0060] As shown in the figure, the vibration power in the region above the first inflection curve 208 is much smaller than that in the region below it. This indicates that the rigidity of the portion of the outer panel 20 near the first inflection curve 208 is high. Therefore, even if a large force acts near the first inflection curve 208 when the door 100 is opened or closed, or even if an external impact acts on the portion, the portion of the outer panel 20 near the first inflection curve 208 will not easily deform.

[0061] Furthermore, the vibration power of the lower region 218, which is below the first inflection curve 208, is much greater than the vibration power of the upper region 216, which is above the first inflection curve 208. Furthermore, looking at the lower region 218, the vibration power of the rear lower region 226 is greater than that of the front lower region 224. Therefore, the lower region 218, and particularly the rear lower region 226, emits a heavy bass sound when the door is closed.

[0062] In the above-described embodiment, the majority of the adhesive portions 50 are provided between the convex vertices 212 and the concave vertices 214, but it is preferable that the number of adhesive portions 50 arranged in this region be in the range of 70% to 90% of the total number of adhesive portions 50.

[0063] [Second embodiment] A vehicle door 100 according to a second embodiment of the present invention will be described with reference to FIG.

[0064] Like Fig. 6, Fig. 8 is a front view of the door located near the driver's seat or passenger seat on the front side of the vehicle, as seen on the right side of the vehicle, that is, the side that appears on the right side when the vehicle is viewed from the rear toward the front, and adds to the configuration shown in Fig. 6 a center of gravity 250 of the outer panel 20, and a horizontal line 252 and a vertical line 254 that pass through the center of gravity 250. Therefore, the configuration of the outer panel 20 shown in Fig. 8 is the same as the configuration of the outer panel 20 shown in Fig. 6, and the same or corresponding parts are designated by the same reference numerals and their explanations will be omitted.

[0065] In the following description, the four regions defined by horizontal line 252 and vertical line 254, i.e., the upper front region, upper rear region, lower rear region, and lower front region, which appear in order along the counterclockwise direction on the drawing, will be referred to as first quadrant 271, second quadrant 272, third quadrant 273, and fourth quadrant 274, respectively.

[0066] However, this designation identifies the four areas on the door on the right side of the vehicle, and in the case of the front door on the left side of the vehicle, the upper front area, upper rear area, lower rear area, and lower front area, which appear in that order in a clockwise direction when viewing the door from outside the vehicle, correspond to the first quadrant, second quadrant, third quadrant, and fourth quadrant, respectively.

[0067] As shown in the figure, the center of gravity 250 of the outer panel 20 is located approximately in the center of the band-shaped recess 204. Furthermore, most of the upper first panel rein portion 42 extends diagonally downward from the front end to the rear end of the door 100 through the first quadrant 271 and the second quadrant 272, while the lower second panel rein portion 44 extends diagonally downward from the front end to the rear end of the door 100 through the first quadrant 271, the fourth quadrant 274, and the third quadrant 273.

[0068] In terms of the number of adhesive portions 50, all of the adhesive portions 50 for the first panel rain portion 42 are distributed in the first quadrant 271 and the second quadrant 272, and the number of adhesive portions 50 in the first quadrant 271 and the second quadrant 272 is approximately the same. However, the number of adhesive portions 50 included in either the first quadrant 271 or the second quadrant 272 may be greater than the number of adhesive portions 50 included in the other quadrant.

[0069] The adhesive portions 50 for the second panel rain portion 44 are distributed in the first quadrant 271 and the fourth quadrant 274, and there are no adhesive portions 50 in the third quadrant 273. However, the number of adhesive portions 50 in the fourth quadrant 274 is smaller than the number of adhesive portions 50 in each of the first quadrant 271 and the second quadrant 272. Also, the third quadrant 273 may have fewer adhesive portions 50 than the fourth quadrant 274.

[0070] Thus, in the embodiment, the number of adhesive portions 50 included in the first quadrant 271 and the second quadrant 272 is smaller than the number of adhesive portions 50 included in each of the third quadrant 273 and the fourth quadrant 274, and the number of adhesive portions 50 included in the fourth quadrant 274 is greater than the number of adhesive portions 50 included in the third quadrant 273.

[0071] By arranging the adhesive portions 50 in this manner, the outer panel 20 and the panel rein 40 supporting it are more integrated in the first quadrant 271 and the second quadrant 272 than in the third quadrant 273 and the fourth quadrant 274. Also, the outer panel 20 and the panel rein 40 supporting it are more integrated in the fourth quadrant 274 than in the third quadrant 273.

[0072] As a result, the rigidity of the first quadrant 271 and the second quadrant 272 of the outer panel 20 is greater than the rigidity of the third quadrant 273 and the fourth quadrant 274, so even if an occupant touches the first quadrant 271 or the second quadrant 272 of the outer panel 20 hard or if an external impact acts thereon, the outer panel 20 will not easily deform.

[0073] Furthermore, the number of adhesive portions 50 in the third quadrant 273 is smaller than the number of adhesive portions 50 in the other first quadrant 271, second quadrant 272, and fourth quadrant 274. As a result, the sound emitted from the third quadrant 273 has the lowest frequency and is the most profound sound.

[0074] [Other embodiments] Although the present invention has been described above as being applied to a door located near the driver's seat or the passenger seat, it can also be applied to a door located near the rear seat. Furthermore, the present invention is not limited to doors installed in automobiles, but can be widely applied to doors of other vehicles.

[0075] In addition, in the above embodiment, the panel rain 40 is composed of two panel rain sections 42, 44, but the panel rain may be composed of a single plate material, or may be composed of three or more panel rain sections. [Explanation of symbols]
