Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to automotive weatherstrips that provide a seal between the door and body of a vehicle. [Background technology]

[0002] For example, as disclosed in Patent Documents 1 and 2, a weather strip is attached to a door inner panel disposed on the side of an automobile to ensure watertightness between the door and the body. In Patent Document 1, a cutout is formed in the rear of the door inner panel. The weather strip in Patent Document 1 includes a waist cover portion disposed to cover the cutout of the door inner panel.

[0003] The weatherstrip in Patent Document 2 has a hollow seal portion that extends along the lower end and front and rear edges of the door inner panel, and a rear end that is attached to the part of the door inner panel that faces the center pillar. The hollow seal portion extends to the inside of the rear end of the weatherstrip and is molded integrally with the rear end. A resin member molded from resin is provided at the rear end of the weatherstrip so as to fit the step of the door inner panel. This resin member has a resin exposed portion that is attached to the step-shaped door inner panel, and an inner portion that is formed continuously with the resin exposed portion and is embedded in the rear end of the weatherstrip.

[0004] [Patent Document 1] JP 2000-351322 A [Patent Document 2] JP 2005-205964 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, when a cutout is formed in the door inner panel as in Patent Document 1, the weather strip is structured with a waist cover portion that covers the cutout in the door inner panel, but since a cutout is formed, ensuring the rigidity of the waist cover portion becomes an issue.

[0006] In particular, when the hollow sealing portion extends to the inside of the vehicle at the rear end of the weatherstrip, as in Patent Document 2, and the rear end of the weatherstrip is attached so as to cover the cutout in the door inner panel, there is a concern that the rear end of the weatherstrip could easily be deformed by the repulsive force of the hollow sealing portion that elastically contacts the body when the door is closed, resulting in a deterioration in the sealing ability of the hollow sealing portion.

[0007] In response to this, it is conceivable that the inner portion of the resin member of Patent Document 2 could be embedded into the rear end of the weatherstrip to ensure the rigidity of the rear end of the weatherstrip and prevent the rear end of the weatherstrip from easily deforming due to the repulsive force of the hollow seal portion that elastically contacts the body when the door is closed.

[0008] However, when molding the hollow seal portion, a core is required to mold the inner surface of the hollow seal portion, and the core must be removed from the hollow seal portion after molding. If the rear end of the weather strip is difficult to deform because the inner part of the resin member is embedded in the rear end when removing the core from the hollow seal portion, it will require a lot of work to remove the core, and there is a high possibility that a part of the hollow seal portion will tear when the core is removed. In other words, from the standpoint of ensuring the sealing performance of the hollow sealing portion, it is advisable to embed a resin or metal member in the rear end of the weatherstrip and increase the rigidity of the rear end with the resin or metal member. However, if the rigidity of the rear end of the weatherstrip is increased in this way, it becomes difficult to remove the core after the hollow sealing portion is molded, resulting in a problem of poor workability during manufacturing.

[0009] The present disclosure has been made in consideration of such points, and its purpose is to improve the sealing performance of the hollow seal portion when the door is closed, while making it easier to remove the core from the hollow seal portion during manufacturing, thereby improving workability during manufacturing. [Means for solving the problem]

[0010] In order to achieve the above object, one aspect of the present disclosure can be premised on an automobile weather strip that is attached to one of a door and a body of an automobile and elastically contacts the other of the door and the body when the door is closed to seal between the door and the body. The automobile weather strip includes a mounting plate made of an elastic material and attached to one of the door and the body, a hollow seal wall made of an elastic material and integrally molded with the mounting plate so as to bulge from the mounting plate toward the other of the door and the body, and a reinforcing embedded plate made of a resin material or a metal material harder than the elastic material constituting the mounting plate and embedded in the mounting plate.

[0011] The mounting plate includes an interior mounting plate extending toward the interior side of the vehicle beyond the hollow seal wall, an exterior mounting plate extending toward the exterior side of the vehicle beyond the hollow seal wall, and a base side mounting plate provided between the interior mounting plate and the exterior mounting plate and connected to the base of the hollow seal wall. The buried plate includes an interior buried plate buried in the interior mounting plate, and an exterior buried plate separate from the interior buried plate and buried in the exterior mounting plate. An end of the interior buried plate and an end of the exterior buried plate are formed to reach the inside of the base side mounting plate.

[0012] According to this configuration, when the door is closed with the mounting plate attached to one of the door and the body, the hollow seal wall elastically contacts the other of the door and the body. At this time, inside the base-side mounting plate to which the base of the hollow seal wall is connected, the end of the vehicle-interior buried plate made of a resin material or metal material harder than the elastic material constituting the mounting plate and the end of the vehicle-exterior buried plate are located, so that the rigidity of the base-side mounting plate is increased by the ends of these buried plates. This suppresses deformation of the base-side mounting plate receiving the repulsive force of the hollow seal wall, and therefore sufficiently improves the sealability between the door and the body.

[0013] On the other hand, when manufacturing a weather strip, a core is used to form the inner surface of the hollow seal wall. After forming the mounting plate and the hollow seal wall, the core is removed from the hollow seal wall. At this time, since the vehicle interior buried plate and the vehicle exterior buried plate that reach the inside of the base mounting plate are separate, the vehicle interior buried plate and the vehicle exterior buried plate are allowed to move relative to each other, and it is possible to stretch the base mounting plate, for example. This makes it easier to remove the core from the hollow seal wall.

[0014] In addition, a core removal hole can be provided in the upper or lower part of the hollow sealing wall to remove the core that forms the inner surface of the hollow sealing wall, so that the core can be removed from the core removal hole in the hollow sealing wall after molding.

[0015] In addition, the end of the interior embedded plate and the end of the exterior embedded plate can be brought close to each other, which further enhances the effect of suppressing deformation of the base side mounting plate receiving the repulsive force of the hollow seal wall.

[0016] This also makes it possible to increase the setting range of the embedded plate, thereby increasing the range in which the sealing material described below can be pressed down, thereby further improving the sealing performance.

[0017] In addition, a plurality of first protrusions protruding toward the vehicle exterior may be formed at an end of the interior buried plate at intervals in the vertical direction, and a plurality of second protrusions protruding toward the vehicle interior may be formed at an end of the exterior buried plate at intervals in the vertical direction. In this case, the second protrusions may be disposed between the first protrusions adjacent in the vertical direction, and the first protrusions may be disposed between the second protrusions adjacent in the vertical direction. This allows the end of the interior buried plate and the end of the exterior buried plate to have a so-called labyrinth structure, further enhancing the effect of suppressing deformation of the base-side mounting plate receiving the repulsive force of the hollow seal wall. In addition, the first protrusions and the second protrusions may be rectangular or arc-shaped. Effect of the Invention

[0018] As described above, the interior buried plate and the exterior buried plate, made of hard resin material, are separate bodies, and the ends of each buried plate are positioned inside the base side mounting plate to which the base of the hollow sealing wall in the weatherstrip mounting plate is connected.This improves the sealing performance of the hollow sealing portion when the door is closed, while also making it easier to remove the core from the hollow sealing portion during manufacture.

[0020] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that the following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses.

[0021] FIG. 1 is a left side view of an automobile 100 equipped with an automobile weather strip 1 according to an embodiment of the present invention. A front door 110 and a rear door 210 are attached to the left and right sides of the automobile 100 so as to be able to open and close. The front door 110 has a door main body 111 and a windshield 112. The door main body 111 of the front door 110 is attached to a front pillar (not shown) of the vehicle body via a hinge (not shown) configured to be rotatable around a rotation axis extending in the vertical direction. Similarly to the front door 110, the rear door 210 also has a door main body 211 and a rear glass 212, and the door main body 211 is attached to a center pillar (not shown) via a hinge (not shown) configured to be rotatable around a rotation axis extending in the vertical direction.

[0022] In the description of this embodiment, the front side of the vehicle is simply referred to as the front, the rear side of the vehicle is simply referred to as the rear, the outside in the vehicle width direction is referred to as the outside side, and the inside in the vehicle width direction is referred to as the inside side.

[0023] Fig. 2 is a left view of the automotive weather strip 1. The automotive weather strip 1 having such a shape is attached to a door body 111 of a front door 110. As shown in Figs. 3 and 4, the door body 111 of the front door 110 has an inner panel 115 that configures the vehicle interior side of the door body 111, and an outer panel 116 that configures the vehicle exterior side of the door body 111.

[0024] In Figs. 5 to 7, the outer panel 116 is omitted, and the inner panel 115 is shown. As shown in Fig. 5, a cutout 117 is formed in the rear portion of the upper part of the inner panel 115. The cutout 117 is open upward. A front edge 117a of the cutout 117 extends in the vertical direction. A lower edge 117b of the cutout 117 extends rearward from the lower end of the front edge 117a. A rear edge 117c of the cutout 117 extends upward from the rear end of the lower edge 117b.

[0025] The rear portion of the inner panel 115 includes a rear plate 115a extending in the front-rear direction, a first intermediate plate 115b extending from the front end of the rear plate 115a toward the vehicle interior, a second intermediate plate 115c extending forward from the end of the first intermediate plate 115b on the vehicle interior side, a third intermediate plate 115d extending from the front end of the second intermediate plate 115c toward the vehicle interior side, and a fourth intermediate plate 115e extending forward from the end of the third intermediate plate 115d on the vehicle interior side. The cutout portion 117 is formed from the third intermediate plate 115d to the rear plate 115a. The shape of the rear portion of the inner panel 115 is not limited to the above-mentioned shape, and may be any shape having at least a plate portion extending in the vehicle interior and exterior direction and a plate extending in the front-rear direction.

[0026] As shown in FIG. 1 and FIG. 2, the weather strip 1 for an automobile has a lower edge portion 1A extending in the front-rear direction along the lower portion of the door body portion 111, a front edge portion 1B extending upward from the front end portion of the lower edge portion 1A along the front portion of the door body portion 111, a rear edge portion 1C extending upward from the rear end portion of the lower edge portion 1A along the rear portion of the door body portion 111, a front molded portion 1D integrally molded on the upper portion of the front edge portion 1B, and a rear molded portion 1E integrally molded on the upper portion of the rear edge portion 1C. The lower edge portion 1A, the front edge portion 1B, and the rear edge portion 1C have the same hollow cross section, and are extrusion molded portions, for example. The lower edge portion 1A, the front edge portion 1B, and the rear edge portion 1C are fixed to the door body portion 111. The shape of the weather strip 1 for an automobile shown in the figure is an example, and it can be any shape depending on the shape of the door body portion 111, the shape of the body 120, etc.

[0027] The front mold part 1D and the rear mold part 1E are molded parts formed by an openable and closable mold (not shown). The front mold part 1D is molded integrally with the upper end of the front edge part 1B, and the rear mold part 1E is molded integrally with the upper end of the rear edge part 1C. As shown in FIG. 3, the front mold part 1D is attached to the front part of the upper part of the inner panel 115 (not shown). Similarly, the rear mold part 1E is attached to the rear part of the upper part of the inner panel 115.

[0028] 5, a rear mounting hole 115f for mounting the rear portion of the rear mold portion 1E is formed in a portion above the lower edge 117c of the cutout 117 of the rear plate 115a. Similarly, a front mounting hole 115g for mounting the front portion of the rear mold portion 1E is formed in a portion above the lower edge 117c of the cutout 117 of the fourth intermediate plate 115e.

[0029] The line indicated by the reference character L1 in Figures 2 to 5 and 7 is the boundary line between the rear molded part 1E and the upper end of the rear edge part 1C. Moreover, the line indicated by the reference character L2 in Figure 2 is the boundary line between the front molded part 1D and the upper end of the front edge part 1B. In this embodiment, the case where the present invention is applied to the rear molded part 1E will be described, but this is not limiting, and the present invention can also be applied to the front molded part 1D.

[0030] In this embodiment, the case where the automobile weather strip 1 is attached to the front door 110 will be described, but the present invention is not limited to this, and the automobile weather strip 1 may be attached to the body 120 (shown in FIG. 1) (not shown). The body 120 is the vehicle body to which the front door 110 is attached, and includes the above-mentioned front pillar, center pillar, side sill, roof, etc. When the automobile weather strip 1 is attached to the front door 110, it elastically contacts the body 120 when the front door 110 is closed to seal between the front door 110 and the body 120. When the automobile weather strip 1 is attached to the body 120, it elastically contacts the front door 110 when the front door 110 is closed to seal between the front door 110 and the body 120. The automobile weather strip 1 may also be attached to the rear door 210 (not shown).

[0031] As shown in Figs. 3 to 7, the rear molded portion 1E includes a mounting plate 20 attached to a plate portion of the inner panel 115 extending at least in the vehicle interior / exterior direction, a hollow seal wall 30 integrally molded with the mounting plate 20, and reinforcing embedded plates 40, 41 embedded in the mounting plate 20. The mounting plate 20 and the hollow seal wall 30 are made of elastic materials such as rubber and thermoplastic elastomer (TPE). Examples of rubber include EPDM, and examples of TPE include TPO (olefin-based thermoplastic elastomer). These elastic materials may be unfoamed solid materials or foamed sponge materials. The embedded plates 40, 41 are shaped as shown in Figs. 8 and 9, as will be described in detail later.

[0032] As shown in Figs. 3 to 7, the hollow seal wall 30 extends in the up-down direction. The lower end of the hollow seal wall 30 is connected to the upper end of the rear edge portion 1C, and the boundary line L1 is the boundary between the lower end of the hollow seal wall 30 and the upper end of the rear edge portion 1C. The portion of the hollow seal wall 30 above the vertical center is integrally formed on the vehicle interior side of the mounting plate 20, and is formed so as to bulge from the mounting plate 20 toward the body 120. The upper end of the hollow seal wall 30 is located below the vertical center of the mounting plate 20.

[0033] As shown in FIG. 5, the lower part of the hollow seal wall 30 extends downward beyond the lower end of the mounting plate 20. A core removal hole 31 for removing a core (not shown) is provided at the front of the lower part of the hollow seal wall 30. The core is a metal member for molding the inner surface of the hollow seal wall 30, and is used when integrally molding the hollow seal wall 30 and the mounting plate 20. After molding the hollow seal wall 30, it is necessary to remove the core from the hollow seal wall 30, so the core removal hole 31 is provided as a hole for removing the core. In this embodiment, the core removal hole 31 is formed in a slit shape that is long in the vertical direction, but is not limited to this shape. Although not shown, the core removal hole may be provided at the upper part of the hollow seal wall 30.

[0034] 5 and 6, the mounting plate 20 is attached to a portion of the inner panel 115 where the cutout portion 117 is formed and the periphery thereof, so that the cutout portion 117 is covered by the mounting plate 20 attached to the inner panel 115. That is, as shown in Fig. 10, which is a cross section taken along line XX in Fig. 3, the mounting plate 20 has an interior mounting plate 21 extending toward the interior side of the vehicle beyond the hollow seal wall 30, an exterior mounting plate 22 extending toward the exterior side of the vehicle beyond the hollow seal wall 30, and a base side mounting plate 23 provided between the interior mounting plate 21 and the exterior mounting plate 22.

[0035] 10, the hollow seal wall 30 has an inner wall 32 located on the vehicle interior side and an outer wall 33 located on the vehicle exterior side, with the tip of the inner wall 32 continuing to the tip of the outer wall 33. The base of the inner wall 32 is connected to the vicinity of the connection between the vehicle interior mounting plate 21 and the base side mounting plate 23. Similarly, the base of the outer wall 33 is connected to the vicinity of the connection between the vehicle exterior mounting plate 22 and the base side mounting plate 23.

[0036] The base of the inner wall 32 and the base of the outer wall 33 of the hollow seal wall 30 are spaced apart from each other in the vehicle interior / exterior direction and the front-rear direction. Specifically, the base of the inner wall 32 is located on the vehicle interior side of the base of the outer wall 33. In addition, the base of the inner wall 32 is located forward of the base of the outer wall 33.

[0037] More specifically, the interior mounting plate 21 is a portion of the mounting plate 20 located closer to the interior of the vehicle than a portion to which the base of the inner wall 32 is connected, and the exterior mounting plate 22 is a portion of the mounting plate 20 located closer to the exterior of the vehicle than a portion to which the base of the outer wall 33 is connected. In other words, the base-side mounting plate 23 is configured from the portion to which the base of the inner wall 32 is connected to the portion to which the base of the outer wall 33 is connected.

[0038] 5 and 6, a separate seal material 25 is attached to the surface of the mounting plate 20 facing the vehicle exterior. The seal material 25 is made of, for example, a highly foamed sponge. The sealing material 25 has a first seal portion 25a extending in the vertical direction along the fourth intermediate plate 115e at the front of the mounting plate 20, a second seal portion 25b extending from the lower end of the first seal portion 25a along the third intermediate plate 115d toward the outside of the vehicle, a third seal portion 25c extending rearward from the outside end of the second seal portion 25b along the second intermediate plate 115c, and a fourth seal portion 25d extending from the rear end of the third seal portion 25c along the first intermediate plate 115b at a downward incline toward the outside of the vehicle, and extending beyond the center core hole 31 at a position above the center core hole 31.

[0039] The first seal portion 25a elastically contacts a portion forward of the front edge portion 117a of the cutout portion 117 in the inner panel 115. The second seal portion 25b, the third seal portion 25c, and the fourth seal portion 25d all elastically contact a portion below the lower edge portion 117b of the cutout portion 117 in the inner panel 115. As shown in Figs. 3, 4, and 6, the first seal portion 25a of the seal material 25 is provided to stop water that has passed between the windshield 112 and the interior mounting plate 21 and reached the vicinity of the cutout portion 117 from penetrating into the interior of the vehicle through the fourth intermediate plate 115e of the inner panel 115. Next, the second seal portion 25b and the third seal portion 25c of the seal material 25 are provided to guide the stopped water to the exterior of the vehicle and then to the rear. Finally, the fourth seal portion 25d of the seal material 25 is provided so that the guided water is drained through the core removal hole 31 to the outside of the vehicle.

[0040] 3 to 6 and 8 to 10, the buried plates 40, 41 include an interior buried plate 41 embedded in the interior mounting plate 21, and an exterior buried plate 40 that is separate from the interior buried plate 41 and embedded in the exterior mounting plate 22. The material of the interior buried plate 41 and the exterior buried plate 40 is not particularly limited, but is a resin material or a metal material that is harder than the elastic material that constitutes the mounting plate 20 and the hollow seal wall 30.

[0041] The vehicle exterior embedded plate 40 has an upper portion 40a that extends above the hollow seal wall 30 and also extends in the front-rear direction, and a lower portion 40b that is located below the upper portion 40a and is embedded in the vehicle exterior mounting plate 22. A rear through hole 40c that coincides with the rear mounting hole 115f of the inner panel 115 is formed in the upper portion 40a of the vehicle exterior embedded plate 40. A rear fixing device 43 is inserted into the rear through hole 40c and the rear mounting hole 115f. The rear portion of the rear molded portion 1E is fixed to the inner panel 115 by the rear fixing device 43.

[0042] The interior embedded plate 41 has an upper part 41a that extends above the hollow seal wall 30 and also extends in the front-rear direction, and a lower part 41b that is located below the upper part 41a and is embedded in the interior mounting plate 21. A front through hole 41c that coincides with the front mounting hole 115g of the inner panel 115 is formed in the upper part 41a of the interior embedded plate 41. A front fixing device 44 is inserted into the front through hole 41c and the front mounting hole 115g. The front part of the rear molded portion 1E is fixed to the inner panel 115 by the front fixing device 44.

[0043] As shown in FIG. 10, the end of the lower portion 40b of the vehicle exterior buried plate 40 and the end of the lower portion 41b of the vehicle interior buried plate 41 are formed to reach the inside of the base side mounting plate 23. The end of the lower portion 40b of the vehicle exterior buried plate 40 and the end of the lower portion 41b of the vehicle interior buried plate 41 are close to each other. Close to each other means that the end of the lower portion 40b of the vehicle exterior buried plate 40 and the end of the lower portion 41b of the vehicle interior buried plate 41 are very close to each other. Specifically, the gap between the end of the lower portion 40b of the vehicle exterior buried plate 40 on the vehicle exterior side and the end of the lower portion 41b of the vehicle interior buried plate 41 on the vehicle interior side is set to, for example, a range of 0.5 mm to 2.0 mm. As a result, the material of the base side mounting plate 23 is filled between the end of the lower portion 40b of the vehicle exterior buried plate 40 and the end of the lower portion 41b of the vehicle interior buried plate 41.

[0044] 8 and 9, a plurality of second protrusions 40d are formed at intervals in the vertical direction at the end of the lower part 40b of the vehicle exterior buried plate 40, and second recesses 40e are formed between the second protrusions 40d aligned in the vertical direction. Also, a plurality of first protrusions 41d are formed at intervals in the vertical direction at the end of the lower part 41b of the vehicle interior buried plate 41, and first recesses 41e are formed between the first protrusions 41d aligned in the vertical direction.

[0045] Furthermore, in order to bring the end of the lower portion 40b of the vehicle exterior buried plate 40 and the end of the lower portion 41b of the vehicle interior buried plate 41 close to each other, the first convex portion 41d is arranged to face between the second convex portions 40d adjacent in the vertical direction, and the second convex portion 40d is arranged to face between the first convex portions 41d adjacent in the vertical direction. In other words, by arranging the second concave portion 40e to face the first convex portion 41d and arranging the first concave portion 41e to face the second convex portion 40d, a labyrinth structure is formed in which the close state is maintained.

[0046] The second protrusion 40d and the first protrusion 41d are formed to be rectangular when the vehicle interior buried plate 41 and the vehicle exterior buried plate 40 are viewed from the thickness direction. Specifically, the second protrusion 40d protrudes forward and is trapezoidal in shape with the edge (front edge) of the protruding tip being the short side. The first protrusion 41d protrudes rearward and is trapezoidal in shape with the edge (rear edge) of the protruding tip being the short side.

[0047] The shapes of the second convex portion 40d and the first convex portion 41d are not limited to a trapezoidal shape, and may be, for example, a rectangle, a square, a triangle, a semicircle, a sector, an arc, etc. Also, without providing the second convex portion 40d, the first convex portion 41d, the second recess 40e, and the first recess 41e, the end of the lower portion 40b of the vehicle exterior buried plate 40 and the end of the lower portion 41b of the vehicle interior buried plate 41 may be formed in a straight line extending in the vertical direction.

[0048] Also, as in the modified embodiment shown in FIG. 11, the end of the lower portion 40b of the exterior buried plate 40 and the end of the lower portion 41b of the interior buried plate 41 may be embedded in the base-side mounting plate 23 in a state where they are aligned in the thickness direction. In this modified embodiment, a bent portion 40f bent rearward is provided at the end of the lower portion 40b of the exterior buried plate 40, and the formation of this bent portion 40f positions the end of the lower portion 40b of the exterior buried plate 40 behind the end of the lower portion 41b of the interior buried plate 41. In this modified embodiment, the material of the base-side mounting plate 23 is filled between the end of the lower portion 40b of the exterior buried plate 40 and the end of the lower portion 41b of the interior buried plate 41. Although not shown, the end of the lower portion 41b of the interior buried plate 41 may be provided with a bent portion bent forward.

[0049] (Effects of the embodiment) As described above, in this embodiment, the mounting plate 20 of the rear molded portion 1E of the weatherstrip 1 can be attached to the inner panel 115 so as to cover the cutout portion 117 of the inner panel 115. Since the vehicle exterior embedded plate 40 and the vehicle interior embedded plate 41 made of a hard resin material or metal material are embedded in the vehicle interior mounting plate 21, the vehicle exterior mounting plate 22 and the base side mounting plate 23 of this mounting plate 20, the rigidity of the vehicle interior mounting plate 21, the vehicle exterior mounting plate 22 and the base side mounting plate 23 of the mounting plate 20 can be ensured. As a result, even if the hollow seal wall 30 elastically contacts the body 120 when the front door 110 is closed and the vehicle exterior mounting plate 22 and the vehicle interior mounting plate 21 receive the repulsive force of the outer wall 33, deformation of the vehicle exterior mounting plate 22 and the vehicle interior mounting plate 21 is suppressed by the vehicle exterior buried plate 40 and the vehicle interior buried plate 41, so that the hollow seal wall 30 can be firmly pressed against the body 120, resulting in a sufficiently high seal between the front door 110 and the body 120. The hollow seal wall 30 pressed against the body 120 deforms and comes into close contact with the body 120.

[0050] On the other hand, when manufacturing the rear molded portion 1E of the weatherstrip 1, a core (not shown) is used to mold the inner surface of the hollow seal wall 30. After the rear molded portion 1E is molded with a mold, the mold is opened, and the core is removed from the core removal hole 31 of the hollow seal wall 30. At this time, since the vehicle exterior embedded plate 40 and the vehicle interior embedded plate 41 that reach the inside of the base side mounting plate 23 are separate bodies, the vehicle exterior embedded plate 40 and the vehicle interior embedded plate 41 are allowed to move relative to each other, and it becomes possible to stretch the base side mounting plate 23, for example. This makes it easier to remove the core that has molded the inner surface of the hollow seal wall 30 from the hollow seal wall 30.

[0051] Furthermore, by using a labyrinth structure that maintains the proximity state as shown in Figures 8 and 9, it is possible to prevent the rear molded portion 1E from rotating or twisting overall with the proximity portion as the boundary after attachment to the door inner panel 115, while maintaining the ability to extract the core.

[0052] Furthermore, by using a modified structure as shown in FIG. 11, it becomes possible to prevent rotation and twisting in the thickness direction of the base side mounting plate 23.

[0053] In addition, in this embodiment, only the case where it is applied to a molded part having a hollow seal wall is illustrated. As explained above, it is also possible to apply this invention to a molded part having a solid seal lip instead of a hollow seal wall (not shown), and in particular, in a molded part having a relatively large embedded plate, applying this invention is effective in preventing deformation of the embedded plate.

[0054] 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. [Industrial Applicability]

[0055] INDUSTRIAL APPLICABILITY As described above, the weather strip for an automobile according to the present invention can be used to provide a seal between a door disposed on the side of an automobile and the body. [Explanation of symbols]
