Description

[Technical field]

[0001] The present invention relates to a seal member for sealing a gap in a vehicle body. [Background technology]

[0002] Regarding an opening provided in an automobile body and a hood (cover plate) that opens and closes said opening, structures for sealing the gap between the hood and the edge of the opening when the hood is in the closed position have been known, for example, as described in JP 2000-289466 A (Patent Document 1) and JP 06-298013 A (Patent Document 2). To give an outline of the sealing structures described in Patent Documents 1 and 2, regarding an automobile hood that opens and closes with the rear end side as a pivot point, a sealing member is attached and fixed by a clip to the back surface of the front end of the hood.

[0003] The seal member has a hollow portion and two lip portions protruding from the hollow portion. One of the lip portions elastically contacts the upper end surface of the front member of the vehicle body when the hood is closed. The other lip portion is constantly in contact with a riding surface set on the reverse side of the leading edge of the hood. The riding surface refers to the range in which contact is permitted, and is constituted, for example, by a narrow hemming portion provided along the leading edge of the hood. With these two lip portions, the seal member seals the gap (also called the parting) between the hood in the closed position and the front member of the vehicle body. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2000-289466 A [Patent Document 2] Japanese Patent Application Publication No. 06-298013 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned conventional seal structure has the following problems. The riding surface set on the back surface of the hood leading edge is very narrow. On the other hand, the seal member requires high accuracy when attached to the hood and high dimensional accuracy of the seal member itself. In addition, the seal member may be subject to unexpected deformation due to shocks caused by opening and closing, or due to changes over time.

[0006] If this happens, when the hood is closed, the lip portion of the seal member will shift from the riding surface, causing problems such as an unattractive appearance of the installed state of the seal member and a loss of sealing performance.

[0007] In view of the above-mentioned circumstances, an object of the present invention is to provide a technique that can reliably contact the seal portion of a seal member without shifting from the rear surface of a hood. [Means for solving the problem]

[0008] For this purpose, the seal member according to the present invention is a band-shaped seal member that extends along the opening edge of a vehicle body opening and seals a gap between the opening edge and a hood that covers the vehicle body opening, and includes a band-shaped mounting base that extends along the back surface of the hood and is fixed to the back surface in one side region of the seal member in the band width direction, a band-shaped seal base that is connected to the other side edge of the mounting base in the band width direction in the central region of the seal member and is cantilevered by the mounting base and faces the opening edge, and The seal base is provided with a vehicle body seal portion which is a folded edge that folds back from the other side edge in the width direction of the seal base to one side in the width direction of the seal base and faces the hood, and elastically contacts the opening edge to seal; and a hood seal portion which extends from the fold of the vehicle body seal portion, bulges toward the hood with a curvature that is gentler than the curvature of the folded edge, and elastically contacts the hemming portion on the back surface of the hood to seal, and the mounting base and the seal base are elastic bodies with relatively high rigidity, and the vehicle body seal portion and the hood seal portion are elastic bodies with relatively low rigidity.

[0009] According to the present invention, the hood seal portion that elastically contacts the back surface of the hood to seal has a bulging shape, and the bulging shape has a gentler curvature than the vehicle body seal portion that elastically contacts the opening edge of the vehicle body opening to seal. Therefore, regardless of the accuracy of the seal member or deformation over time, the hood seal portion reliably elastically contacts the other side portion of the back surface of the hood in the band width direction. Furthermore, the vehicle body seal portion elastically contacts the opening edge of the vehicle body opening without any particular problem. Therefore, according to the seal member of the present invention, even though it is a seal member attached to the hood, it is possible to take a seal structure (deflection form) in which the opening edge is the riding surface (and sealing surface) and the hood edge portion (e.g., the hemming portion) is the sealing surface, and it is possible to reliably seal the opening edge of the hood and the vehicle body opening. Furthermore, according to the seal member of the present invention, the hood seal portion and the vehicle body seal portion are neatly fitted into the gap between the opening edge of the vehicle body opening and the hood in the closed position, that is, the so-called edge portion, so that it is possible to seal the edge portion without impairing the appearance. The curvature may be a circular arc or a curve other than a circular arc. The structure of the back surface of the hood is not particularly limited, but for example, an inner panel is provided on the back surface of the hood.

[0010] The shapes of the body seal portion and the hood seal portion are not particularly limited, but in one aspect of the present invention, the seal base has a rising portion that branches off from a middle portion in the width direction of the seal base, rises, and connects to one side edge in the width direction of the hood seal portion. According to this aspect, both sides in the width direction of the hood seal portion are supported by the body seal portion and the rising portion. Therefore, when the hood seal portion contacts the other side portion in the width direction of the hood back surface, the contact surface pressure can be secured. In addition, the other side portion in the width direction of the seal base, the body seal portion, the hood seal portion, and the rising portion form a hollow portion. This hollow portion stabilizes the shape of the seal member when sealed, and improves the sealing performance and durability. In another aspect, the one side edge in the width direction of the hood seal portion may be separated from the seal base, and the hood seal portion may be cantilevered by the body seal portion.

[0011] In a preferred aspect of the present invention, the hood seal portion has a relatively gentle curvature at the other side in the obi width direction and a relatively steep curvature at one side in the obi width direction. According to this aspect, the one side in the obi width direction is easily bent, and when the hood is in the closed position, the hood seal portion moves to one side in the obi width direction. Therefore, the seal member does not protrude outward beyond the boundary between the hood and the opening edge, and the appearance of the seal member 1 is not marred. In addition, the hood seal portion on the other side in the obi width direction, which has a gentle curvature, elastically contacts the other side in the obi width direction of the back surface of the hood in a wide surface form. Therefore, the hood and the opening edge of the vehicle body opening are more reliably sealed.

[0012] In a further preferred aspect of the present invention, the rising portion stands upright or has a curvature that is gentler than that of the other side portion in the obi width direction, and the connection portion between the one side portion in the obi width direction of the hood seal portion and the rising portion has a curvature that is steeper than that of the one side portion in the obi width direction. According to this aspect, the connection portion between the one side portion in the obi width direction of the hood seal portion and the rising portion is easily bent, so that the hood seal portion elastically contacts the other side portion in the obi width direction of the hood back surface in a wide plane. Therefore, the hood and the opening edge of the vehicle body opening are more reliably sealed.

[0013] In a further preferred aspect of the present invention, the seal base has one side portion in the obi width direction closer to the mounting base portion than the rising portion, and the other side portion in the obi width direction closer to the vehicle body seal portion than the rising portion, and the inclination angle of the other side portion in the obi width direction with respect to the opening edge is relatively smaller than the inclination angle of the one side portion in the obi width direction with respect to the opening edge. According to this aspect, since the seal base is not in a straight line and a bending point is formed so that the middle portion in the obi width direction protrudes toward the opening edge, the rising amount of the rising portion can be set longer than when the seal base is in a straight line, the connection portion between the rising portion and the hood seal portion is more easily bent, and the hood seal portion elastically contacts the other side portion in the obi width direction of the hood back surface in a wider surface shape. Therefore, the hood and the opening edge of the vehicle body opening are more reliably sealed.

[0014] The seal base, the body seal, and the hood seal may be made of rubber or an elastic body equivalent to rubber, and the type of rubber is not particularly limited, and the presence or absence of a core material is also not limited. In the case of rubber, for example, EPDM or the like can be used, and in the case of thermoplastic elastomer, for example, TP0 (olefin-based thermoplastic elastomer) or the like can be used. In one aspect of the present invention, the mounting base and the seal base are at least partially formed of a non-foaming material, and the body seal and the hood seal are at least partially formed of a foaming material. According to this aspect, since the seal base and the mounting base are made of a non-foaming material (for example, solid rubber), the deformation amount of the seal base is smaller than that of the sealing area, and the sealing area can be firmly supported. In addition, since the sealing surfaces of the body seal and the hood seal are made of a foaming material (for example, sponge rubber), the adhesion performance of the body seal and the hood seal to the opening edge of the body opening and the hood, which are the mating materials, can be improved. Effect of the Invention

[0015] Thus, according to the present invention, the seal member has excellent robustness and can reliably elastically contact and seal the other side of the hood back surface in the band width direction regardless of the size of the riding surface of the front edge of the hood (in other words, the size of the width dimension of the hemming portion provided on the hood back surface). Therefore, the gap between the opening edge of the vehicle body opening and the hood in the closed position can be reliably sealed. In addition, the seal member fits neatly into the gap between the opening edge of the vehicle body opening and the hood in the closed position, the so-called edge portion, and does not impair the appearance. [Brief description of the drawings]

[0016] [Figure 1] 1 is a schematic perspective view showing a vehicle body and a hood on which a sealing member of the present invention is provided. [Diagram 2] 1 is a cross-sectional view showing a seal member according to a first embodiment of the present invention. [Diagram 3] 3 is a cross-sectional view showing a sealing state of the seal member shown in FIG. 2. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic perspective view showing a hood and a front part of a vehicle body of an automobile to which a sealing member of the present invention is attached and fixed. Fig. 2 is a cross-sectional view showing a state in which the hood is cut along plane II-II in Fig. 1 and the cut surface is viewed in the direction of the arrow. Fig. 3 is a cross-sectional view showing a state in which the hood shown in Fig. 2 is in a closed position. In this specification, left and right refer to the vehicle width direction, and front and rear refer to the front and rear of the vehicle.

[0018] A room 101 is defined in the front of the vehicle body 100 to accommodate an engine, electrical components of the electric vehicle, luggage, etc. The room 101 has a vehicle body opening that is open at least upward. The vehicle body opening is defined by a front grille 103, a left vehicle body panel 105m, a right vehicle body panel 105n, and a dash panel 105. Headlights 109 are disposed on the left and right sides of the front of the vehicle body opening. An opening edge 103a on the front side of the vehicle body opening is formed by the upper surface of the front grille 103 extending in the vehicle width direction.

[0019] The vehicle body opening can be opened and closed by a hood 102. Figs. 1 and 2 show the hood 102 in an open state (also referred to as an open position). A hood rear edge 102e of the hood 102 is connected to the vicinity of a dash panel 105 of the vehicle body 100 by a hinge 107. When the vehicle body 100 is parked on a level road surface as shown in Fig. 1, the hinge 107 allows the angle of the hood 102 to change from the closed position to the open position by less than 90° with respect to the horizontal plane, for example, in the range of 0 to 80°. A seal member 1 is attached to the back surface of the hood 102, specifically, to the inner panel 102b.

[0020] As shown in the cross-sectional view of FIG. 3, the hood 102 is usually in a lower closed position, covering the room 101 in a substantially horizontal position or in a tilted position in which the hood front edge 102c is lower than the hood rear edge 102e (FIG. 1). In such a closed position, the hood front edge 102c is aligned with the front grille 103, and forms a parting portion M (FIG. 3) between the front grille 103 and the opening edge 103a of the front grille 103. Referring to FIG. 3, the hood front edge 102c is located directly above the opening edge 103a, with the flat opening edge 103a as a reference. The opening edge 103a is also connected to the forward inclined surface 103b. The inclined surface 103b also extends downward and forward. The imaginary line connecting the inclined surface 103b and the outer surface of the outer panel 102a is a boundary N that defines the parting portion M. The boundary N shown by the two-dot chain line is, for example, a straight line extending along the hood 102.

[0021] When the hood 102 is in the upper open position as shown in Fig. 1, the hood 102 rotates about the hinge 107 so that the hood leading edge 102c is higher than the hood trailing edge 102e, exposing the vehicle body opening and the room 101. In Fig. 2 and Fig. 3, the approach trajectory F of the hood 102 from the open position to the closed position is shown by a dashed dotted line. The approach trajectory F is a circular arc with the hinge 107 as the center.

[0022] As shown in the cross-sectional view of FIG. 2, the hood 102 has a hood body (outer panel 102a) that spreads out on the upper side, and an inner panel 102b that is fixed to the back side of the outer panel 102a. The outer panel 102a is folded back at the hood front edge 102c of the hood 102 and fixed so as to wrap around the front edge of the inner panel 102b. As a result, the outer panel 102a and the inner panel 102b are joined at the hood front edge 102c. Such a joining point is also called a hemming part H. With reference to the closed position of the hood 102 shown in FIG. 3, the hemming part H extends upward toward the rear and downward toward the front, and is located directly above the opening edge 103a. A sealer 104 is provided at the hemming part H as the joining point. The sealer 104 is a protrusion that covers the edge of the outer panel 102a from the back side of the hood 102, has viscoelasticity, and protects the joint so that the edge of the outer panel 102a does not rust. The material of the sealer 104 is, for example, a resin whose main component is polyvinyl chloride. For convenience, in the following explanation, the inner panel 102b is also simply referred to as the back side of the hood.

[0023] The seal member 1 is a band-shaped member that extends along the vicinity of a hood leading edge 102c of the hood 102, and extends in the vehicle width direction of the hood 102. In the following description, the direction in which the seal member 1 extends as shown in FIG. 1 is also referred to as the longitudinal direction. With respect to the longitudinal direction of the seal member 1, the seal member 1 is divided into a longitudinal central region 10 and end portions 20 at a boundary C. In this embodiment, the end portions 20 are molded by a mold and the longitudinal central region 10 is extrusion molded in the longitudinal direction, with the longitudinal central region 10 and the end portions 20 being joined together at the boundary C.

[0024] The seal member 1 is attached and fixed to the inner panel (hood back surface) 102b of the hood 102 with the obi width direction as the front-rear direction. Specifically, as shown in FIG. 2, a plurality of through holes 11a are formed in the rear edge portion, which is one side portion in the obi width direction, of the longitudinal central region 10 and the end portion 20, and a clip 31 is passed through each through hole 11a, and each clip 31 fits into a panel through hole 102h formed in a corresponding portion of the inner panel 102b provided on the lower surface of the hood 102. In the following description, a portion of the rear edge portion of the seal member 1 where the seal member 1 is fixed to the hood back surface by the clip 31 is referred to as the attachment base 11. A plurality of through holes 11a of the attachment base 11 are provided at intervals in the longitudinal direction of the seal member 1. In this specification, for convenience of description, the obi width direction of the seal member 1 may be referred to as the front-rear direction even if the hood 102 is in the upright position shown in FIG.

[0025] The central region in the band width direction of the seal member 1 is referred to as the seal base 13. The seal base 13 is connected to the other side edge in the band width direction of the above-mentioned mounting base 11 and is cantilevered by the mounting base 11. The seal base 13 also extends toward the opening edge 103a and is connected to the vehicle body seal portion 14d.

[0026] The vehicle body seal portion 14d is the other side edge in the band width direction of the seal member 1, and is a folded edge formed by folding back from the other side in the band width direction to one side in the band width direction.

[0027] The hood seal portion 14c is extended from the vehicle body seal portion 14d. The hood seal portion 14c bulges toward the hood 102 and elastically contacts the back surface of the hood to seal. Specifically, the hood seal portion 14c elastically contacts at least one of the hemming portion H of the outer panel 102a and the sealer 104 to seal.

[0028] The curvature R2 of the bulging shape of the hood seal portion 14c is gentler than the curvature R3 of the vehicle body seal portion 14d, which is the folded edge. In terms of the radius of curvature, the seal surface of the hood seal portion 14c is a gentle curve with a relatively large radius, while the seal surface of the vehicle body seal portion 14d is a steep curve with a relatively small radius.

[0029] Hood seal portion 14b is further extended from hood seal portion 14c. Hood seal portion 14b also bulges toward hood 102 and elastically contacts the back surface of the hood, specifically, sealer 104, to form a seal. The curvature R1 of the bulging shape of hood seal portion 14b is steeper than the curvature R2 of hood seal portion 14c. In terms of the radius of curvature, the sealing surface of hood seal portion 14b is a curve with a medium radius, while the sealing surface of hood seal portion 14c is a gentle curve with a large radius.

[0030] The seal member 1 of this embodiment includes a rising portion 14a that branches off from the middle of the seal base 13 in the band width direction and rises, and connects to one side edge of the hood seal portion 14b in the band width direction. The rising portion 14a is an upright wall, but the surface of the connection portion between the hood seal portion 14b and the rising portion 14a is made into a bulging shape with a curvature R4. The curvature R4 is steeper than the curvature R1 of the hood seal portion 14b and the curvature R2 of the hood seal portion 14c. In terms of the radius of curvature, the surface of the connection portion is a steep curve with a relatively small radius, whereas the seal surfaces of the hood seal portions 14c and 14b are gentle curves with a relatively large radius. Alternatively, as a modified example not shown, the rising portion 14a may be curved to bulge toward the hood 102.

[0031] The above-mentioned vehicle body seal portion 14d, hood seal portions 14c and 14b, and rising portion 14a are arranged in this order from the other side in the obi width direction to one side in the obi width direction. The order of curvature increases in the order of R2, R1, and R3. The curvature R4 should be larger than R1. By providing a difference in curvature between the vehicle body seal portion 14d, the hood seal portions 14c and 14b, and the joints in this way, the larger the curvature, the easier it is to bend, and the hood seal portion 14c can be moved to one side (rear) in the obi width direction as shown in FIG. 3, which will be described in detail later.

[0032] The vehicle body seal portion 14d, the hood seal portions 14c and 14b, and the rising portion 14a are integrally joined to form the seal region 14. Of the seal member 1, the seal region 14 is made of an elastic body having a relatively low rigidity, and the remaining mounting base portion 11 and seal base portion 13 are made of an elastic body having a relatively low rigidity. The difference in rigidity between these two types of elastic bodies may be due to the presence or absence of a core material within the same composition, or due to a difference in wall thickness within the same composition, or due to a difference in composition. As an example of a difference in composition, the seal region 14 may be made of a foam material (e.g., sponge rubber), and the mounting base portion 11 and seal base portion 13 may be made of a non-foam material (e.g., solid rubber).

[0033] The seal base 13 and the seal area 14 are integrally joined to form a hollow portion T. It should be understood that Fig. 2 shows the seal member 1 in its original state (the shape after extrusion molding and before attachment to the hood 102), and the seal area 14 depicted beyond the hood 102 is an estimate of elastic deformation. The estimate is intended to prevent the seal area 14 from moving away from the hood 102 when the hood 102 is in the open position. In the actual attachment state (not shown), the seal base 13 is slightly elastically deformed in a direction away from the hood 102, and the seal area 14 is elastically deformed so that the hollow portion T is compressed, and at least parts of the hood seal portions 14c, 14b elastically contact the hemming portion H of the outer panel 102a and the sealer 104.

[0034] When the hood 102 is in the closed position, the seal member 1 approaches the opening edge 103a in the same direction as the approach trajectory F, and the vehicle body seal portion 14d elastically contacts the opening edge 103a while the seal area 14 is in elastic contact with the hemming portion H and the sealer 104 as shown in FIG. 3. Then, the seal area 14 undergoes large elastic deformation so that the hollow portion T is further compressed. In contrast, the seal base portion 13 undergoes slight elastic deformation so as to approach the hood 102. The difference in the amount of elastic deformation is due to the fact that the seal area 14 is an elastic body with a relatively small rigidity, and the seal base portion 13 is an elastic body with a relatively large rigidity. Also, as shown by the arrow D, the rising portion 14a tilts backward, and the hood seal portions 14c and 14b move backward.

[0035] The seal member 1 of this embodiment has a strip shape extending along an opening edge 103a of the vehicle body opening of the room 101, and seals the gap between the opening edge 103a and the hood . The sealing member 1 includes a band-shaped mounting base 11 that extends along the inner panel 102b, which is the back surface of the hood 102, in one side region in the band width direction of the sealing member 1 and is fixed to the inner panel 102b; a band-shaped seal base 13 that is connected to the other side edge in the band width direction of the mounting base 11 in the central region in the band width direction of the sealing member 1, is cantilevered by the mounting base 11, and faces the opening edge 103a; a vehicle body seal portion 14d that is a folded edge that folds back from the other side edge in the band width direction of the seal base 13 to one side in the band width direction toward the hood 102 in the other side region in the band width direction of the sealing member 1 and elastically contacts the opening edge 103a to seal; and a hood seal portion 14c that extends from the fold of the vehicle body seal portion 14d and bulges toward the hood 102 with a curvature R2 that is gentler than the curvature R3 of the folded edge, and elastically contacts and seals with a hemming portion H of the inner panel 102b, which is the back surface of the hood 102. The mounting base 11 and the seal base 13 are made of elastic bodies having a relatively high rigidity, while the vehicle body seal portion 14d and the hood seal portion 14c are made of elastic bodies having a relatively low rigidity.

[0036] According to this embodiment, the curvature R3 of the vehicle body seal portion 14d is steep, whereas the hood seal portion 14c that elastically contacts and seals with the hood back surface has a bulging shape, and the bulging shape has a curvature R2 that is gentler than the curvature R3 of the vehicle body seal portion 14d that elastically contacts and seals with the opening edge 103a of the vehicle body opening of the room 101. Therefore, even if the width S (FIG. 3) of the hemming portion H (riding surface) of the back surface (inner panel 102b) of the hood 102 becomes smaller due to the sealer 104, the hood seal portion 14c reliably elastically contacts the hemming portion H of the back surface of the hood 102. Also, the vehicle body seal portion 14d elastically contacts the opening edge 103a of the vehicle body opening without any particular problem. Therefore, according to the sealing member 1 of this embodiment, although it is a sealing material attached to the hood 102, contrary to the conventional technique, it is possible to adopt a sealing structure (deflection form) in which the opening edge 103a serves as the riding surface (and sealing surface), and the gap between the hood 102 and the opening edge 103a of the vehicle body opening can be reliably sealed.

[0037] Furthermore, according to this embodiment, due to the bulging shape of the sealing area 14, when the hood 102 is in the closed position, the sealing area 14 fits behind the edge M and does not protrude forward beyond the edge M. Therefore, even when the hood 102 is in the closed position, the appearance of the seal member 1 is not marred. In addition, the unevenness at the edge M is reduced, reducing wind noise when the vehicle is running.

[0038] In addition, the seal member 1 of this embodiment includes a rising portion 14a that branches from the middle portion of the seal base 13 in the band width direction and rises, and connects to one side edge of the hood seal portion 14b in the band width direction, so that both sides of the hood seal portions 14c, 14b in the band width direction are supported by the vehicle body seal portion 14d and the rising portion 14a. Therefore, when the hood seal portions 14c, 14b contact the back surface of the hood 102 (specifically, the hemming portion H of the inner panel 102b), the contact surface pressure can be secured. In addition, the other side portion 13b in the band width direction of the seal base 13, the vehicle body seal portion 14d, the hood seal portions 14c, 14b, and the rising portion 14a form a hollow portion T. The hollow portion T stabilizes the shape of the seal member 1 during sealing, and improves the sealing performance and durability.

[0039] According to this embodiment, the hood seal portion 14c on the other side in the obi width direction has a relatively gentle curvature R2, and the hood seal portion 14b on one side in the obi width direction has a relatively steep curvature R1. Therefore, when the hood 102 is closed as shown by the arrow D in FIG. 3, the hood seal portions 14c, 14b move to one side in the obi width direction (rearward). Therefore, the seal area 14 does not protrude forward from the parting portion M, and the appearance of the seal member 1 is not impaired. In addition, the hood seal portion 14c on the other side in the obi width direction elastically contacts the hemming portion H on the back surface of the hood 102 in a wide surface manner. Therefore, the hood 102 and the opening edge 103a of the vehicle body opening are more reliably sealed.

[0040] In addition, the rising portion 14a of this embodiment stands upright from the seal base 13, and the connection portion between the rising portion 14a and the hood seal portion 14b, which is one side portion of the hood seal portion 14c in the belt width direction, has a curvature R4 that is steeper than that of the hood seal portion 14b. This makes the connection portion easier to bend, and the hood seal portions 14c, 14b elastically contact the back surface of the hood 102 (the hemming portion H and the sealer 104) in a wider surface shape. This makes it possible to more reliably seal the hood 102 and the opening edge 103a of the vehicle body opening.

[0041] In addition, according to this embodiment, the seal base 13 has one side portion 13a in the band width direction that is closer to the mounting base 11 than the rising portion 14a, and the other side portion 13b in the band width direction that is closer to the vehicle body seal portion 14d than the rising portion 14a, and the inclination angle θ1 of the other side portion 13b in the band width direction with respect to the opening edge 103a is relatively smaller than the inclination angle θ2 of the one side portion 13a in the band width direction with respect to the opening edge 103a. As a result, the cross-sectional shape of the seal base 13 is not straight but has an inverted L-shaped cross section, and a folding point that protrudes toward the opening edge 103a is provided in the middle of the cross-sectional shape in the band width direction, so that the amount of rise (rise length) of the rising portion 14a can be set longer than when the seal base 13 is straight (not shown), the connection portion between the rising portion 14a and the hood seal portion 14b is more easily bent, and the hood seal portions 14c, 14b elastically contact the hemming portion H and the sealer 104 on the back surface of the hood 102 in a wider surface shape. Therefore, the hood 102 and the opening edge 103a of the vehicle body opening are more reliably sealed.

[0042] Furthermore, according to this embodiment, the mounting base 11 and the seal base 13 are formed from a non-foaming material such as solid rubber, and the vehicle body seal portion 14d and the hood seal portions 14c, 14b are formed from a foaming material such as sponge rubber, thereby improving the adhesion performance of the vehicle body seal portion 14d and the hood seal portions 14c, 14b to the mating materials, that is, the opening edge 103a and the back surface of the hood (specifically, the hemming portion H of the inner panel 102b).

[0043] Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope. [Industrial Applicability]

[0044] The present invention is advantageously used in engine vehicles, electric vehicles, and hybrid vehicles. Although not shown in the drawings, the present invention can also be applied to a seal member attached to an openable and closable trunk lid that covers a trunk room provided at the rear of the vehicle body, and an openable and closable back door that covers a luggage storage area at the rear of the vehicle body. Although not shown in the drawings, the present invention can also be applied to a vehicle having a protruding portion that protrudes toward the hood side at the front end (front side of the vehicle body seal portion) of the flat portion of the opening edge of the vehicle body opening.
