Description

[Technical field]

[0001] The present invention relates to a seal material for an automobile door that is attached to a door provided in an automobile. [Background technology]

[0002] Conventionally, a sealant has been attached to an automobile door to seal between the door and a door opening in a vehicle body (see, for example, Patent Documents 1 to 3). The sealant in Patent Document 1 has a hollow seal portion and a seal lip that extend in the front-rear direction of the vehicle along the upper edge of the sash. A bag-shaped water storage portion is integrally molded at the front end of the sealant, and rainwater that flows forward near the base of the seal lip is temporarily stored in the water storage portion. The opening of this water storage portion is oriented toward the front of the vehicle, and the rainwater stored in the water storage portion flows out from the water storage portion in the forward direction.

[0003] The seal material of Patent Document 2 also has a hollow seal portion and a seal lip extending in the vehicle front-rear direction along the upper edge of the sash. Figure 4 of Patent Document 2 shows a wall extending in the vehicle width direction from the hollow seal portion to the seal lip.

[0004] The sealing material of Patent Document 3 is a hollow weatherstrip having a portion extending in the front-rear direction of the vehicle along the upper edge of the sash and a portion extending in the front-rear direction along the lower part of the door. In the peripheral wall of this hollow weatherstrip, upper slits that allow rainwater to flow in are intermittently formed in the portion along the upper edge of the sash, and drainage slits are intermittently formed in the portion extending along the lower part of the door. Therefore, rainwater that flows into the hollow weatherstrip from the upper slits flows inside the hollow weatherstrip and is drained from the drainage slits. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2004-051054 A [Patent Document 2] JP 2006-069494 A [Patent Document 3] Japanese Utility Model Application Publication No. 64-030716 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the case of the sealing material of Patent Document 1, the water storage section is disposed on the upper part of the sash, so there is a risk that the water flowing out from the water storage section will flow downward and get on the door opening and closing device. If the water gets on the door opening and closing device, it may freeze in cold regions and cause problems in opening and closing the door.

[0007] In addition, in Patent Document 2, there is a wall extending in the vehicle width direction from the hollow seal portion to the seal lip. However, if a large amount of rainwater flows between the hollow seal portion and the seal lip, there is a risk that the rainwater will flow downward over the wall and get onto the door opening and closing device. As a result, in cold regions, the rainwater may freeze, causing problems with opening and closing the door.

[0008] In addition, in Patent Document 3, since the drainage slit is located at the bottom of the door, there is no risk of water drained from the drainage slit getting onto the door opening and closing device, but since the upper slit formed on the upper edge of the sash is formed intermittently, the rain gutter function is not provided over the entire upper edge of the sash. As a result, there is still a possibility that a problem will occur in which rainwater will get over the hollow weather strip and enter the vehicle interior.

[0009] The present invention has been made in consideration of such points, and its purpose is to prevent water that has entered between the upper end of the door and the vehicle body from entering the vehicle compartment, and to make it possible to drain the water so that it does not come into contact with the door opening and closing device.

[0010] Here, in the present invention, the terms are defined as follows. "Outside the vehicle compartment" refers to the portion of the flange portion at the upper end of the door that is outside the vehicle compartment outer surface in FIG. 1 of Patent Document 3. Also, "between the upper end of the door and the vehicle body" refers to the gutter portion that is formed by the outer lip portion, the inner lip portion, and the root portions of both lips in the upper slit-defined portion in FIG. 1 of Patent Document 3. Also, "inside the vehicle compartment" refers to the portion that is inside the portion where the inner lip portion at the upper slit-defined portion elastically contacts the roof portion of the vehicle in FIG. 1 of Patent Document 3. [Means for solving the problem]

[0011] In order to achieve the above object, in a first aspect of the present disclosure, an automobile door seal material 1 that is attached to one door 300 that opens and closes a door opening 103 formed on a side of a body 101 of an automobile 100 and seals between the one door opening 103 and the one door 300 is provided with an upper edge mounting portion 30 that is attached to the upper edge portion 322 of a frame 320 of the one door 300 in a portion extending in the vehicle front-rear direction along the upper edge portion 322 of the frame 320 of the one door 300, an upper edge mounting portion 30 that is attached to the upper edge portion 322, an upper edge outer seal lip 31 that elastically contacts the vehicle body 101 when the one door 300 is closed, and an upper edge inner seal lip 32 that is positioned away from the upper edge outer seal lip 31 toward the passenger compartment side and elastically contacts the vehicle body 101 when the one door 300 is closed, and between the upper edge outer seal lip 31 and the upper edge inner seal lip 32, a seal material that is fixed to the upper edge outer seal lip 31 and the vehicle body 101 is provided. and a vertical side upper attachment portion 20 attached to the vertical side portion 321 of the frame 320 of the one door 300, a support wall portion 21 extending from the vertical side upper attachment portion 20 to the outside of the vehicle compartment, and a support wall portion 21 extending from the vertical side upper attachment portion 20 to the outside of the vehicle compartment and projecting from the support wall portion 21 to one side in the vehicle longitudinal direction and supporting the other door 300 when the one door 300 and the other door 200 are closed. A vertical side seal portion 2 is provided having a vertical side upper seal lip 22 that elastically contacts the door 200, and a vertical side upper water guide groove 24 is formed between the vertical side upper mounting portion 20 and the vertical side upper seal lip 22. An upper mold portion 5 is provided which connects the other side end of the upper side seal portion 3 to the upper end of the vertical side seal portion 2, and the upper side water guide groove 34 and the vertical side upper water guide groove 24 are connected via the upper mold portion 5.

[0012] According to this configuration, when the door 300 is closed, the upper outer seal lip 31 and the upper inner seal lip 32 extending along the upper edge portion 322 of the frame 320 of the door 300 elastically contact the vehicle body 101. At this time, the upper outer seal lip 31 and the upper inner seal lip 32 are disposed at intervals from each other in the interior and exterior directions of the vehicle and are easily deflected and deformed, so that the reaction force acting on the door 300 is reduced at the moment the door 300 is closed. Therefore, the closing performance of the door 300 is improved.

[0013] Furthermore, when the door 300 is closed, the upper outer seal lip 31 is in elastic contact with the vehicle body, but water may enter between the upper end of the door 300 and the outer seal surface 101b of the vehicle body 101. The entered water flows in the upper water guide groove 34 between the upper outer seal lip 31 and the upper inner seal lip 32 in the front-rear direction of the vehicle.

[0014] At this time, since the upper-side water guide groove 34 and the vertical-side upper water guide groove 24 are connected via the upper mold part 5, water flowing in the upper-side water guide groove 34 in the front-to-rear direction of the vehicle flows in the vertical-side upper water guide groove 24 via the upper mold part 5. This makes it difficult for water to get on the door opening / closing devices 213, 311, 315.

[0015] In the second aspect of the present disclosure, the upper mold section 5 is provided with an upper mold section upper side water guide groove 54 connected to the other end 34Fe of the upper side water guide groove 34, and an upper mold section vertical side water guide groove 59 connected to the other end 54Fe of the upper mold section upper side water guide groove 54, and a lower end 59Le of the upper mold section vertical side water guide groove 59 is connected to an upper end 24Ue of the vertical side upper water guide groove 24, and the upper side water guide groove 34 is formed in a frame 322 of an outer panel 324 that constitutes the outer side of the vehicle cabin of the upper side portion 322 of the frame 320. The upper mold portion vertical side water guiding groove 59 is positioned inside the vehicle cabin more than the flange vertical side portion 326a of the outer panel 324 that constitutes the outer side of the vehicle cabin of the vertical side portion 321 of the frame 320, and the upper end portion 59Ue of the upper mold portion vertical side water guiding groove 59 is positioned inside the vehicle cabin more than the flange vertical side portion 326b of the outer panel 324 that constitutes the outer side of the vehicle cabin of the vertical side portion 321 of the frame 320, and the lower portion 59L of the upper mold portion vertical side water guiding groove 59 extends downward from the upper end portion 59Ue and extends to the outer side of the vehicle cabin more than the flange vertical side portion 326b of the outer panel 324 that constitutes the outer side of the vehicle cabin of the vertical side portion 321 of the frame 320.

[0016] According to this configuration, the infiltrated water flows in the vehicle front-rear direction through the upper side water guide groove 34 between the upper side outer seal lip 31 and the upper side inner seal lip 32. The water that passes through one end 34Fe of the upper side water guide groove 34 in the vehicle front-rear direction and flows to one end 54Fe of the upper mold part upper side water guide groove 54 passes through the upper mold part vertical side water guide groove 59, flows into the vertical side upper side water guide groove 24 from the upper end 24Ue of the vertical side water guide groove 24, and flows downward. At this time, the lower part 59L of the upper mold part vertical side water guide groove 59 below the upper end 59Ue extends downward and extends to the outside of the vehicle compartment beyond the flange vertical side part 326b of the outer panel 324 of the vertical side part 321 of the frame 320, so that the water in the upper mold part vertical side water guide groove 59 is guided to the outside of the vehicle compartment beyond the flange vertical side part 326b of the outer panel 324. This makes it even more difficult for water to get on the door opening and closing devices 213, 311, and 315.

[0017] In a third aspect of the present disclosure, a lower mold part 8 is connected to the lower end of the vertical side seal part 2, and a vertical side lower seal part 6 is connected to the lower end of the lower mold part 8, a lower mold part water guide groove 84 is connected to the lower end 24Le of the vertical side upper water guide groove 24, and a vertical side lower water guide groove 64 is connected to the lower end 84Le of the lower mold part water guide groove 84, and the lower end 64Le of the vertical side lower water guide groove 64 is positioned below the door opening and closing devices 213·311·315 that open and close the one door 300 and the other door 200.

[0018] With this configuration, the top seal portion 3, upper mold portion 5, vertical side seal portion 2, lower mold portion 8, and vertical side lower seal portion 6 are integrally molded, so that water flowing through the water guiding groove hardly leaks on the way, and since the lower end portion 64Le of the vertical side lower water guiding groove 64 is positioned below the door opening and closing devices 213, 311, and 315, water is drained below the door opening and closing devices 213, 311, and 315. This also makes it possible to further prevent water from getting on the door opening and closing devices 213, 311, and 315.

[0019] In the fourth aspect of the present disclosure, the bottom 54b of the upper mold portion upper side water guiding groove 54 is formed so as to be positioned lower as it approaches one end 54Fe in the vehicle front-rear direction.

[0020] According to this configuration, water in the upper mold portion upper side water guiding groove 54 flows in one direction in the front-to-rear direction of the vehicle and easily flows into the vertical side upper water guiding groove 24.

[0021] In the fifth aspect of the present disclosure, the vertical side upper mounting portion 20 has an inner wall portion 20a arranged on the interior side of the vehicle cabin of a flange vertical side portion 326b extending in the vertical direction of the vertical side portion 321, an outer wall portion 20b arranged on the exterior side of the vehicle cabin of the flange vertical side portion 326b, and a connecting wall portion 20c extending from the inner wall portion 20a to the outer wall portion 20b and connecting the inner wall portion 20a and the outer wall portion 20b, and the support wall portion 21 is formed so as to protrude toward the exterior of the vehicle cabin from the other end of the outer wall portion 20b in the fore-and-aft direction of the vehicle, and the vertical side upper water guide groove 24 is formed by the vertical side upper seal lip 22, the outer wall portion 20b, and the support wall portion 21.

[0022] According to this configuration, by clamping the flange vertical side portion 326b of the vertical side portion 321 of the frame 320 between the inner wall portion 20a and the outer wall portion 20b of the vertical side upper mounting portion 20, the vertical side upper mounting portion 20 can be attached to the flange vertical side portion 326b of the vertical side portion 321. In this case, since the vertical side upper seal lip 22, the outer wall portion 20b and the support wall portion 21 can be used to form the vertical side upper water guide groove 24, it is not necessary to set a shape just for forming the water guide groove 24.

[0023] In the sixth aspect of the present disclosure, a vertical side core material 25 made of a material harder than the vertical side upper seal lip 22 is embedded in the inner wall portion 20a, the outer wall portion 20b and the connecting wall portion 20c.

[0024] With this configuration, the vertical side upper mounting portion 20 can be firmly attached to the flange vertical side portion 326b of the vertical side portion 321, thereby suppressing deformation or displacement of the vertical side upper water guide groove 24 and guiding water to the desired location.

[0025] In a seventh aspect of the present disclosure, the vertical-side upper seal lip 22 is curved or inclined so as to be positioned toward the inside of the vehicle compartment as it approaches one end in the vehicle front-rear direction.

[0026] According to this configuration, the opening width of the vertical-side upper water guiding groove 24 can be narrowed, so that water in the vertical-side upper water guiding groove 24 is less likely to leak out of the vertical-side upper water guiding groove 24.

[0027] In the eighth aspect of the present disclosure, the upper outer seal lip 31 can be brought into elastic contact with the vehicle body 101 in a curved or inclined state so as to be positioned outside the vehicle compartment as it approaches the upper end portion.

[0028] According to this configuration, the sealing pressure at the seal portion where the upper outer seal lip 31 is in elastic contact with the vehicle body 101 is increased, so that the amount of water that infiltrates can be reduced. Effect of the Invention

[0029] As described above, according to the present disclosure, in a door sealing material of a type that reduces the door closing force, water that has entered between the upper end of the door and the vehicle body can be prevented from entering the vehicle compartment, and the water can be guided to one end of the vehicle and then to the outside of the vehicle compartment, and guided below the door opening and closing device, so that the water can be drained without coming into contact with the door opening and closing device.

The boundary between the front vertical seal section 2 and the lower mold section 8 is indicated by symbol L5, and the boundary between the front vertical lower seal section 6 and the lower mold section 8 is indicated by symbol L6.

[0059] The material constituting the automobile door seal material 1 is not particularly limited as long as it is a rubber-like elastic body, but in the case of rubber, EPDM sponge rubber is preferred, and in the case of thermoplastic resin, foamed TPO or soft TPO is preferred.

[0060] Also, as shown in Figure 13, the portion of the sealing material 1 for automobile doors extending in the fore-and-aft direction along the upper edge portion 322 of the frame 320 is provided with an upper edge mounting portion 30 attached to the upper edge portion 322, an upper edge outer seal lip 31 that elastically contacts the outer seal surface 120b of the roof portion (vehicle body) 120 when the rear door 300 is closed, and an upper edge inner seal lip 32 that is positioned away from the upper edge outer seal lip 31 toward the passenger compartment inside, extends in the fore-and-aft direction, and elastically contacts the inner seal surface 120c of the roof portion (vehicle body) 120 when the rear door 300 is closed.

[0061] The portion of the automobile door seal material 1 that extends in the front-rear direction along the upper edge portion 322 includes the upper edge seal portion 3 and the upper edge portion 5a of the upper mold portion 5. The upper edge mounting portion 30 is formed so as to extend along the upper edge seal material mounting plate portion 325a in the upper edge portion 322, and is the portion that is attached to the upper edge seal material mounting plate portion 325a. For example, the lower surface of the upper edge mounting portion 30 can be attached to the upper edge seal material mounting plate portion 325a by an adhesive material (not shown) such as double-sided tape, but this is not limited to this, and it may be attached by an attachment member such as a clip (not shown).

[0062] 10 (cross section along line XX in FIG. 8), an upper mold part core material 55 is embedded in the lower part of the upper mold part upper side mounting part 50 and the upper mold part upper side outer seal lip 51. The upper mold part core material 55 is a member made of a material harder than the rubber-like elastic body constituting the upper part of the upper mold part upper side outer seal lip 51 and the upper mold part upper side inner seal lip 52, and is in the form of a plate that extends in the up-down direction and also extends continuously in the front-rear direction.

[0063] The upper mold core 55 has a bent central portion in the vertical direction so that the portion embedded in the lower portion of the upper mold part upper side outer seal lip 51 is located closer to the outside of the vehicle cabin than the portion embedded in the upper mold part upper side mounting part 50. A lower protrusion 53b is formed near the lower end of the upper mold part upper side outer seal lip 51, protruding toward the outside of the vehicle cabin and extending in the front-rear direction. The tip of the lower protrusion 53b is in elastic contact with the lower end of the inner panel upper plate part 325b. An upper mold part upper side back lip 53a is formed near the upper end of the upper mold part upper side outer seal lip 51, protruding toward the outside of the vehicle cabin and extending in the front-rear direction. The tip of the upper mold part upper side back lip 53a is in elastic contact with the vehicle interior surface of the bent part 324a.

[0064] 13, the lower portion of the upper edge outer seal lip 31 extends in the vertical direction, while the upper portion is inclined or curved so as to be positioned outside the vehicle compartment as it approaches its upper end. The upper edge outer seal lip 31 elastically contacts the vehicle-exterior seal surface 120b of the roof portion 120, so that the upper portion of the upper edge outer seal lip 31 elastically contacts the vehicle-exterior seal surface 120b of the roof portion 120 in a curved or inclined state so as to be positioned outside the vehicle compartment as it approaches its upper end.

[0065] The upper edge inner seal lip 32 is inclined or curved so as to be positioned toward the inside of the vehicle compartment as it approaches its upper end. The upper edge inner seal lip 32 elastically contacts the vehicle interior seal surface 120c of the roof portion 120, so that the upper edge inner seal lip 32 as a whole is deflected and deformed toward the outside of the vehicle compartment. When the rear door 300 is closed, the upper end of the upper edge outer seal lip 31 and the upper end of the upper edge inner seal lip 32 are both in elastic contact with the roof portion 120, but the points where the two upper ends are in elastic contact are separated in the vehicle interior and exterior directions.

[0066] Furthermore, when the rear door 300 is closed, a closed space is formed by the interior surface of the upper side outer seal lip 31, the exterior surface of the upper side inner seal lip 32, and the roof portion 120, and it is possible that rainwater or water from washing the car (hereinafter referred to as rainwater, etc.) may infiltrate into the interior of the vehicle through a gap between the upper side outer seal lip 31 and the exterior seal surface 120b of the roof portion 120 (W1 in FIG. 13). Note that the rainwater, etc. that infiltrates into the interior of the vehicle through a gap between the upper side outer seal lip 31 and the exterior seal surface 120b of the roof portion 120 is prevented from infiltrating into the interior of the vehicle by the upper side inner seal lip 32.

[0067] Between the upper side outer seal lip 31 and the upper side inner seal lip 32, an upper side water guide groove 34 is formed, through which rainwater or the like that has infiltrated between the upper side outer seal lip 31 and the vehicle-exterior seal surface 120b of the roof portion 120 can flow in the front-rear direction. The entire upper side water guide groove 34 from its front end to its rear end is disposed on the passenger compartment side of the outer panel 324 of the flange upper side portion 326a of the frame 320. As a result, rainwater or the like in the upper side water guide groove 34 flows inside the passenger compartment further than the outer panel 324 (W1 in FIG. 13).

[0068] 8, the bottom 54b of the upper mold part upper side water guiding groove 54 is formed to be located lower as it approaches the front end 54Fe. This allows the height of the bottom 54b of the upper side water guiding groove 54 to be changed depending on the location, allowing rainwater, etc. in the upper mold part upper side water guiding groove 54 to flow toward the front side (W2 in FIGS. 8 to 10).

[0069] As shown in FIG. 12, the portion of the sealing material 1 for automobile doors that extends vertically along the front vertical side portion 321 of the frame 320 of the rear door 300 is provided with a vertical side upper mounting portion 20 that is attached to the front vertical side portion 321, a support wall portion 21 that extends from the vertical side upper mounting portion 20 toward the outside of the vehicle compartment, and a vertical side upper seal lip 22 that protrudes forward from the support wall portion 21 and elastically contacts the front door 200 when the front door 200 and the rear door 300 are closed.

[0070] 8, the portion of the automobile door seal material 1 extending in the vertical direction along the front vertical side portion 321 includes the front vertical side seal portion 2 and the vertical side portion 5b of the upper mold portion 5. As shown in Fig. 12, the vertical side upper attachment portion 20 is a portion attached to the flange front vertical side portion 326b of the front vertical side portion 321, and extends in the vertical direction along the flange front vertical side portion 326b.

[0071] Specifically, the vertical side upper attachment portion 20 has an inner wall portion 20a arranged on the vehicle interior side of the flange front vertical side portion 326b, an outer wall portion 20b arranged on the vehicle exterior side of the flange front vertical side portion 326b, and a connecting wall portion 20c extending from the inner wall portion 20a to the outer wall portion 20b. The connecting wall portion 20c is a portion that connects the front end portion of the inner wall portion 20a to the front end portion of the outer wall portion 20b. The vertical side upper attachment portion 20 has a shape that is open rearward due to the inner wall portion 20a, the outer wall portion 20b, and the connecting wall portion 20c, and the flange front vertical side portion 326b can be inserted between the inner wall portion 20a and the outer wall portion 20b.

[0072] The flange front vertical side portion 326b inserted between the inner wall portion 20a and the outer wall portion 20b is held by a plurality of holding lips 20a1 provided on the outer side surface of the inner wall portion 20a and a plurality of holding protrusions 20b1 provided on the inner side surface of the outer wall portion 20b. A vertical side core material 25 made of a material harder than the vertical side upper seal lip 22 is embedded in the inner wall portion 20a, the outer wall portion 20b and the connecting wall portion 20c.

[0073] The vertical-side core material 25 is a member made of a hard material similar to the upper mold portion core material 55. The cross-sectional shape of the vertical-side core material 25 is a shape that opens toward the rear similar to the cross-sectional shape of the vertical-side upper mounting part 20. By embedding the vertical-side core material 25, the clamping force of the vertical-side upper mounting part 20 on the flange front vertical side part 326b can be improved, and the vertical-side upper mounting part 20 can be firmly attached.

[0074] The support wall portion 21 is formed so as to protrude from the rear end of the outer wall portion 20b toward the outside of the vehicle compartment and extend in the vertical direction. The rear end of the support wall portion 21 is adapted to elastically contact the front end of the garnish 327. The vertical side upper seal lip 22 protrudes forward from the end of the support wall portion 21 on the outside of the vehicle compartment, extends in the vertical direction, and is curved or inclined so as to be located inside the vehicle compartment as it approaches the front end. Although not shown, when the front door 200 is open, the front end of the vertical side upper seal lip 22 is separated from the front end of the outer wall portion 20b or the end of the connecting wall portion 20c on the outside of the vehicle compartment toward the outside of the vehicle compartment, and a gap is formed between the vertical side upper seal lip 22 and the vertical side upper mounting portion 20.

[0075] On the other hand, when the front door 200 and the rear door 300 are both closed, the rear end of the front door 200 elastically contacts the outer surface of the vertical-side upper seal lip 22, and the vertical-side upper seal lip 22 as a whole elastically deforms so as to bend toward the inside of the vehicle compartment. As a result, the front end of the vertical-side upper seal lip 22 elastically contacts the front end of the outer wall portion 20b or the end of the connecting wall portion 20c on the outer side of the vehicle compartment, thereby closing the gap between the vertical-side upper seal lip 22 and the vertical-side upper mounting portion 20. The vertical-side upper seal lip 22, the outer wall portion 20b, and the support wall portion 21 form a vertical-side upper water guide groove 24 extending in the up-down direction.

[0076] As shown in Fig. 8, the upper end 24Ue of the vertical-side upper water guide groove 24 is connected to the front end Fe of the upper-side water guide groove 34 via the upper mold section vertical-side water guide groove 59 and the upper mold section upper-side water guide groove 54, so that water is smoothly drained (W2 → W3 → W4 → W5 in Fig. 8). The front vertical-side lower seal portion 6 has a vertical-side lower water guide groove 64 having a cross-sectional shape similar to that of the front vertical-side seal portion 2, as shown in Figs. 2 and 3. As shown in Fig. 4, the front vertical-side lower seal portion 6 extends to the lower end of the door main body 310, so that the lower end 64Le of the vertical-side lower water guide groove 64 is located at the lower end of the door main body 310.

[0077] That is, more specifically, as shown in Figure 8, an upper mold part 5 is provided which connects the other end of the upper edge seal part 3 and the upper end of the front vertical edge seal part 2, and the upper mold part 5 is provided with an upper mold part upper edge side water guide groove 54 which is connected to the other end 34Fe of the upper edge water guide groove 34, and an upper mold part vertical edge side water guide groove 59 which is connected to the other end 54Fe of the upper mold part upper edge side water guide groove 54, and the lower end 59Le of the upper mold part vertical edge side water guide groove 59 is connected to the upper end 24Ue of the vertical edge upper side water guide groove 24. More specifically, as shown in FIG. 7, the lower end 24Le of the upper vertical side water guiding groove 24 is connected to the upper end 84Ue of the lower mold part water guiding groove 84, and the lower end 84Le of the lower mold part water guiding groove 84 is connected to the upper end 64Ue of the lower vertical side water guiding groove 64, and as shown in FIG. 4, the lower end 64Le of the lower vertical side water guiding groove 64 is positioned at the lower end of the door main body portion 310.

[0078] As a result, water W5 in the vertical-side upper water guiding groove 24 is drained at a position below the door latch device 213, the door hinge 311, and the door checker 315 (W5→W6→W7 in FIG. 7).

[0079] 5 and 8, the upper end 59Ue of the upper mold portion vertical side water guiding groove 59 is connected to the front end 54Fe of the upper mold portion upper side water guiding groove 54, and is therefore disposed inside the vehicle cabin relative to the flange upper side portion 326a of the outer panel 324 of the upper side portion 322 of the frame 320. The lower portion 59L of the upper mold portion vertical side water guiding groove 59 extends downward from the upper end 59Ue and extends further outside the vehicle cabin than the flange upper side portion 326a of the outer panel 324.

[0080] That is, the portion below the upper end portion 59Ue of the upper mold portion vertical side water guiding groove 59 has an upper mold portion vertical side water guiding groove lower portion 59L that extends downward and is bent toward the outside of the vehicle compartment. The formation of this upper mold portion vertical side water guiding groove lower portion 59L makes it possible to position the upper end portion 59Ue on the inside of the vehicle compartment relative to the flange upper edge portion 326a of the outer panel 324, while positioning the lower side on the outside of the vehicle compartment relative to the flange upper edge portion 326a of the outer panel 324, thereby enabling water to be guided to the outside of the vehicle compartment (W3 → W4 in Figures 5, 6, and 8).

[0081] Furthermore, as shown in FIG. 11 (cross-sectional view taken along line XI-XI in FIG. 8), in the vertical side portion 5b of the upper mold portion 5, an upper mold portion vertical side tip mounting portion 56b is provided in front of the upper mold portion vertical side mounting portion 56a, an upper mold portion vertical side support wall portion 57 is provided extending from the vehicle exterior surface of the upper mold portion vertical side tip mounting portion 56b toward the outside of the vehicle, and an upper mold portion vertical side outer seal lip 58 is provided extending at an angle from the vehicle exterior portion of the upper mold portion vertical side support wall portion 57 toward the inside of the vehicle.

[0082] Here, in the vertical side portion 5b of the upper mold section 5, the flange front vertical side portion 326b is located outside the upper mold section vertical side support wall portion 57. Also, as shown in Fig. 12 (a cross-sectional view of line XII-XII in Fig. 8), in the portion where the front vertical side seal portion 2 is attached, the flange front vertical side portion 326b is located inside the outer wall portion 20b. That is, as shown in Figs. 5, 11, and 12, the water guide groove of the automobile door seal material 1 is displaced from the inside to the outside of the vehicle in the section where the flange front vertical side portion 326b is located on the outside and rear side, and in the section below that, the flange front vertical side portion 326b is displaced from the outside to the inside of the vehicle, so that the flange front vertical side portion 326b does not cross or interfere with the displaced section of the water guide groove, thereby ensuring smooth water guide.

[0083] (Effects of the embodiment) As described above, according to this embodiment, when the rear door 300 is closed as shown in Fig. 13, the upper side outer seal lip 31 and the upper side inner seal lip 32 of the upper side seal portion 3 elastically contact the roof portion 120. In addition, when the front door 200 is closed as shown in Fig. 12, the vertical side upper seal lip 22 elastically contacts the rear end portion of the front door 200.

[0084] When rainwater or the like seeps into the passenger compartment between the upper-side outer seal lip 31 and the outer seal surface 120b of the roof portion 120 with the rear door 300 closed, the rainwater or the like may flow forward through the upper-side water guide groove 34. The rainwater or the like that has flowed forward through the upper-side water guide groove 34 passes from the front end portion 34Fe of the upper-side water guide groove 34 through the upper mold portion upper-side water guide groove 54 and the upper mold portion vertical-side water guide groove 59, flows into the upper end portion 24Ue of the vertical-side upper water guide groove 24, and flows downward through the vertical-side upper water guide groove 24.

[0085] Here, since the upper mold portion vertical side water guide groove 59 has an upper mold portion vertical side water guide groove lower portion 59L that is bent toward the outside of the vehicle compartment, rainwater, etc. in the upper mold portion vertical side water guide groove 59 can be guided to the outside of the vehicle compartment beyond the outer panel 324.

[0086] Furthermore, since the vertical-side upper water guide groove 24 is connected to the vertical-side lower water guide groove 64 of the front vertical-side lower seal portion 6 via the lower mold portion water guide groove (not shown), it extends below the lower rear door hinge 311, so that rainwater, etc. can be guided below the lower rear door hinge 311 and drained from near the lower end of the door main body portion 310. This makes it possible to prevent rainwater, etc. that has infiltrated between the upper end of the rear door 300 and the roof portion 120 from coming into contact with the rear door latch device 213, the rear door hinge 311, and the rear door checker 315.

[0087] The above-described embodiment is merely illustrative in all respects and should not be construed as limiting. Furthermore, all modifications and variations within the scope of the claims are within the scope of the present invention.

[0088] In the above embodiment, the sealing material for an automobile door is attached to a rear door, but the present invention can also be applied to a front door, and further, to a right door or a left door of an automobile. [Industrial Applicability]

[0089] As described above, the automobile door seal material according to the present invention can be used in, for example, a rear door. [Explanation of symbols]
