Waterstop member
[0001] The present disclosure relates to a waterstop member.
[0002] In a vehicle, for example, a grommet is attached to a wiring member that connects a device on the vehicle body side and a device on the door side (for example, Patent Document 1). The grommet covers, for example, a portion routed between the vehicle body and the door in the wiring member, and is attached to the vehicle body at one end side and attached to the door at the other end side. The grommet makes liquid-tight contact with the vehicle body or the door at the portion attached to the vehicle body or the door, and prevents liquid from entering through the gap therewith.
[0003] International Publication No. 2020 / 059392
[0004] For example, due to long-term use, the contact portion of the grommet with the vehicle body or the door may deteriorate. In such a case, for example, the desired waterstop performance can be maintained by replacing the grommet with a new one, but a technique that can more simply maintain the waterstop performance has been demanded.
[0005] Therefore, an object of the present disclosure is to provide a technique that can simply maintain the waterstop performance.
[0006] The waterstop member of the present disclosure is a waterstop member attached to an attachment target surface of a vehicle, and includes a main body portion having an opposing surface disposed to face the attachment target surface, and a long waterstop component interposed between the attachment target surface and the opposing surface, and the waterstop component is a waterstop member that is detachably attached to the main body portion.
[0007] According to the present disclosure, the waterstop performance can be simply maintained.

[0009] [Description of Embodiments of the Disclosure] First, embodiments of the Disclosure will be listed and described.
[0010] The water-stopping member of this disclosure is as follows:
[0011] (1) A water-stopping member that is attached to a mounting surface of a vehicle, comprising a main body having an opposing surface positioned opposite to the mounting surface, and an elongated water-stopping component interposed between the mounting surface and the opposing surface, wherein the water-stopping component is replaceably attached to the main body.
[0012] By replacing the water-stopping components, the water-stopping performance can be easily maintained.
[0013] (2) In the water-stopping member of (1), it is also preferable that the main body portion is provided with a groove along the water-stopping path defined on the opposing surface, and that the water-stopping component can be detachably fitted into the groove. This is because the water-stopping component can be replaced by pulling out the existing water-stopping component from the groove of the main body portion and fitting a new water-stopping component into the groove.
[0014] (3) In the water-stopping member of (2), it is preferable that the water-stopping component comprises a long connecting portion that is fitted into the groove, and a sealing portion of the connecting portion that protrudes from the surface exposed from the groove when it is fitted into the groove, and extends along the extending direction of the surface, and that the dimensions of the sealing portion are smaller than the dimensions of the connecting portion in the width direction intersecting the extending direction. This is because the water-stopping component can be stably attached to the main body by fitting the connecting portion, which is wider than the sealing portion, into the groove. Also, because the sealing portion that contacts the mounting surface is narrower than the connecting portion, the surface pressure between the sealing portion and the mounting surface is increased, and sufficient water-stopping performance can be achieved.
[0015] (4) It is also preferable that any one of the water-stopping members from (1) to (3) has an adhesive portion for bonding the water-stopping component to the main body. This is because the water-stopping component can be replaced by peeling off the existing water-stopping component that is bonded to the main body and bonding a new water-stopping component to the main body.
[0016] (5) In any one of the water-stopping members described in (1) to (4), it is preferable that the water-stopping member comprises a locking portion provided on one of the water-stopping component and the main body, and a locked portion provided on the other of the water-stopping component and the main body, wherein the locking portion is detachably locked to the locked portion. This is because the water-stopping component can be replaced by releasing the locking between the main body and the locking portion provided on one of the existing water-stopping components and the locked portion provided on the other, removing the existing water-stopping component from the main body, and then attaching the new water-stopping component to the main body by locking the locking portion provided on one of the new water-stopping components and the locked portion provided on the other.
[0017] In the water-stopping member of (6)(5), it is also preferable that the locking portion has a projection, the locked portion has a hole, and the projection is inserted into the hole and locked in the hole. This is because the locking portion can be easily locked into the locked portion.
[0018] (7) In the water-stopping member of (6), it is also preferable that the main body or the water-stopping component comprises a first portion and a second portion which has higher rigidity than the first portion, and that the hole is provided in the second portion. This is because providing the hole in the second portion which has higher rigidity than the first portion makes the hole less likely to deform, and the projection is stably locked in place.
[0019] (8) In any one of the water-sealing members of (1) to (7), it is also preferable that the water-sealing member is the portion attached to the door of a grommet that guides a wiring member along the door panel of the vehicle. This is because the water-sealing performance can be easily maintained by replacing only the water-sealing part, without having to replace the entire grommet.
[0020] (9) In any one of the water-sealing members described in (1) to (7), it is also preferable that the water-sealing member is the portion attached to the through-hole of a grommet that guides a wiring member through the through-hole provided in the vehicle. This is because the water-sealing performance can be easily maintained by replacing only the water-sealing part, without having to replace the entire grommet.
[0021] [Details of Embodiments of the Disclosure] Specific examples of the water-stopping members of the Disclosure will be described below with reference to the drawings. However, the Disclosure is not limited to these examples and is intended to include all modifications within the meaning and scope of the claims, as indicated by the claims.
[0022] [Embodiment 1] <1. Vehicle> The vehicle 100 according to Embodiment 1 will be described with reference to Figure 1. Figure 1 is a schematic perspective view showing a part of the vehicle 100.
[0023] The vehicle 100 comprises a body 1, a door 2, and a grommet 3.
[0024] (Body 1) Body 1 is the main body of the vehicle 100 and is made of metal, for example (sheet metal). Body 1 is provided with an opening (door opening). Specifically, body 1 is provided with a side plate portion (body side plate portion) 11 that defines the door opening.
[0025] (Door 2) Door 2 is provided to close a door opening provided in the body 1. Door 2 may be a side door (driver's side door, passenger side door, or rear passenger side door) or a back door. Door 2 is connected to the body 1, for example, via a hinge (not shown), and rotates around the hinge to close or open the door opening.
[0026] Door 2 includes a panel 21. Panel 21 is made of, for example, metal (sheet metal, for instance), and serves as the framework of door 2. Panel 21 includes, for example, an outer panel 21a and an inner panel 21b. The outer panel 21a, together with the body 1, constitutes the exterior appearance of the vehicle 100. The inner panel 21b is provided on the passenger compartment side of the outer panel 21a. A door trim (not shown) is attached to the inner panel 21b. The door trim is an interior component that constitutes the interior design of door 2, and is made of, for example, resin. The inner panel 21b includes an inner panel portion (door inner panel portion) 211 and a side panel portion (door side panel portion) 212. The door inner panel portion 211 is positioned with a gap between it and the outer panel 21a, and is positioned on the passenger compartment side of the outer panel 21a when door 2 is closed. The door side panel portion 212 extends from the edge of the door inner panel portion 211 toward the outer panel 21a. When the door 2 is closed, the door side panel portion 212 faces the body side panel portion 11. The inner panel 21b comprises the door inner panel portion 211 and the door side panel portion 212, creating a space between the outer panel 21a and the inner panel 21b. Various devices are housed in this space.
[0027] A weatherstrip 22 is attached to the door 2, separating the interior and exterior of the vehicle. The weatherstrip 22 is a long, elongated member made of an elastic material (for example, rubber), and is attached along the interior edge of the door side panel portion 212. As will be described later, a grommet 3 is attached to the door side panel portion 212, and the weatherstrip 22 is installed overlapping the grommet 3 (specifically, the base portion 41 of the first water-stopping member 32i (described later)) and crossing it. When the door 2 is closed, the weatherstrip 22 is in liquid-tight contact with the body side panel portion 11, preventing liquid from entering the portion on the interior side of the weatherstrip 22 (i.e., water is stopped).
[0028] (Grommet 3) The grommet 3 covers the wiring member W routed between the body 1 and the door 2, and is attached to the body 1 (specifically, the body side panel portion 11) at one end and to the door 2 (specifically, the door side panel portion 212) at the other end (a so-called door grommet). The wiring member W transmits power, signals, etc. between equipment installed on the body 1 and equipment installed on the door 2 (a so-called wire harness). The wiring member W may include, for example, one or more electric wires or one or more optical fiber cables.
[0029] <2. Grommets> Grommets 3 will be explained in detail with reference to Figures 1, 2, and 4. Figure 2 is a schematic perspective view showing the grommet 3 removed from the vehicle 100. Figure 3 is a schematic plan view showing the grommet 3 attached to the vehicle 100. Figure 4 is a schematic perspective view showing the grommet 3. For the sake of explanation, in the following, the side where the body side panel portion 11 is located will be referred to as the "front side" and the side where the door side panel portion 212 is located will be referred to as the "rear side".
[0030] <2-1. Overall Configuration> The grommet 3 comprises, for example, a cylindrical portion 31, a water-stopping member (first water-stopping member) 32i provided at one end of the cylindrical portion 31, and a water-stopping member (second water-stopping member) 32j provided at the other end of the cylindrical portion 31.
[0031] The cylindrical portion 31 is a cylindrical member. Here, the wiring member W is pulled out from inside the body 1 through a through hole (mounting hole) H1 that penetrates the body side plate portion 11 in the thickness direction, routed to the door side plate portion 212, and guided along the door side plate portion 212. The portion of the wiring member W that is routed between the body side plate portion 11 and the door side plate portion 212 is inserted through the inside of the cylindrical portion 31. As a result, the area around this portion is covered by the cylindrical portion 31, protecting and waterproofing that portion. The cylindrical portion 31 is formed, for example, in a bellows shape and is made to be deformable (for example, bendable and expandable). The door side plate portion 212 is positioned in close proximity to and opposite to the body side plate portion 11 when the door 2 is closed, and moves away from the body side plate portion 11 when the door 2 is opened. The cylindrical portion 31 deforms to follow this change in positional relationship.
[0032] The first watertight member 32i is attached to the door 2 (specifically, the door side panel portion 212) to ensure watertightness (waterproofing) between it and the door. The first watertight member 32i also protects and waterproofs the wiring member W while guiding the wiring member W along the door side panel portion 212 (i.e., along a path that does not penetrate the door side panel portion 212). In other words, the first watertight member 32i is the portion of the grommet 3 (a so-called through-less grommet) that guides the wiring member W along the panel 21 of the door 2 and is attached to the door 2.
[0033] The second watertight member 32j is attached to the body 1 (specifically, to the mounting hole H1 provided in the body side plate portion 11) to ensure watertightness between them. The second watertight member 32j also protects and waterproofs the wiring member W while guiding the wiring member W through the mounting hole H1 (i.e., along the path that penetrates the body side plate portion 11). In other words, the second watertight member 32j is the part of the grommet 3 that guides the wiring member W through the mounting hole H1 and is attached to the mounting hole H1.
[0034] <2-2. First Water-Sealing Member> The configuration of the first water-sealing member 32i will be described in detail. The first water-sealing member 32i comprises a main body (first main body) 321i and a water-sealing component (first water-sealing component) 322i.
[0035] (a) First main body portion 321i The first main body portion 321i comprises a base portion 41. The base portion 41 is made of an elastic material (an elastic material, for example, rubber (for example, EPDM: ethylene propylene diene rubber), elastomer, etc.). The base portion 41 is, for example, a thin semicircular plate in plan view, and comprises a pair of semicircular main surfaces (front surface 41a and rear surface 41b) and a side surface 41c provided between them. The front surface 41a is provided with an opening (front opening) H2 on the side of the curved edge. On the other hand, the rear surface 41b is provided with an opening (rear opening) H3 on the side of the straight edge. The cylindrical portion 31 is connected to the front opening H2, and the wiring member W inserted through the cylindrical portion 31 is guided into the base portion 41 through the front opening H2, traverses the base portion 41 radially, and is led out of the base portion 41 through the rear opening H3. However, a support 42 made of a material with higher rigidity than the base portion 41 (for example, metal, resin, etc.) is embedded in the base portion 41, and the portion of the wiring member W that is disposed inside the base portion 41 is covered by the support 42. In other words, the wiring member W is supported by the support 42, which has relatively high rigidity, and the base portion 41, which has relatively low rigidity (relatively high elasticity), is provided so as to surround the support 42. A fixing portion 43 made of a material with higher rigidity than the base portion 41 (for example, metal, resin, etc.) is provided on the front surface 41a. The fixing portion 43 is fixed to the front surface 41a while traversing the front surface 41a in the chord direction, and each end is provided so as to extend to the outside of the front surface 41a. Through holes H4 for inserting bolts Q are provided at each end of the fixing portion 43.
[0036] Here, a recess 5 is provided on the front surface 212a of the door side panel portion 212 for attaching the first main body portion 321i. The recess 5 has a shape corresponding to the base portion 41 and opens into the door inner panel portion 211 at one end. The depth of the recess 5 is approximately the same as the thickness of the base portion 41. The base portion 41 is positioned in the recess 5 with its rear surface 41b facing the bottom surface 5a of the recess 5 and its side surface 41c facing the side surface 5b of the recess 5. With the base portion 41 positioned in the recess 5, the through hole H4 provided in the fixing portion 43 is positioned opposite the fixing hole H5 provided in the door side panel portion 212. The first main body portion 321i is attached to the door side panel portion 212 by fastening a bolt Q through the opposing through hole H4 and fixing hole H5 in sequence. In this state, the straight edge of the base portion 41 protrudes into the passenger compartment, exposing the rear opening H3, and the wiring member W led out from the rear opening H3 is routed along the inner door panel portion 211. In other words, the wiring member W is protected and waterproofed by the first watertight member 32i, and is routed along the door side panel portion 212 and further along the inner door panel portion 211 to connect to equipment installed in the door 2.
[0037] As described above, the first main body portion 321i (and consequently the first water-stopping member 32i) is attached to the door side panel portion 212. Here, the surface on the vehicle 100 to which the first main body portion 321i is attached is called the "attachment surface D". Also, the surface of the first main body portion 321i that is positioned opposite the attachment surface D when the first main body portion 321i is attached to the vehicle 100 is called the "opposing surface Dt". Here, for example, the attachment surface D is the front surface 212a of the door side panel portion 212, and the opposing surface Dt is the rear surface 41b and the side surface 41c of the base portion 41.
[0038] (b) First water-sealing component 322i The first water-sealing component (lip) 322i is a long member and is arranged along a defined path (water-sealing path) defined on the opposing surface Dt. The water-sealing path is, for example, a path that divides (separates) the opposing surface Dt into the interior side and the exterior side when the first main body 321i is attached to the door side plate portion 212. As an example, the water-sealing path is a path that crosses the rear surface 41b of the base portion 41, which is the opposing surface Dt, in the chord direction. Also, at each end in the extending direction, the water-sealing path is a path that crosses the side surface 41c of the base portion 41, which is the opposing surface Dt, in the thickness direction (thickness direction of the base portion 41). Multiple water-sealing paths that do not intersect (independent) may be defined on the opposing surface Dt. In this case, the multiple water-sealing paths may include a first water-sealing path defined on the interior side of the vehicle interior than the weatherstrip 22 when the first main body portion 321i is attached to the door side panel portion 212, and a second water-sealing path defined on the exterior side of the vehicle interior than the weatherstrip 22 in the same state.
[0039] As described above, when the first main body portion 321i is attached to the door side panel portion 212, the opposing surface Dt faces the mounting surface D. In this state, the elongated first water-sealing component 322i, which is arranged along the water-sealing path defined on the opposing surface Dt, is interposed between the opposing surface Dt and the mounting surface D (specifically, between the rear surface 41b of the base portion 41 and the bottom surface 5a of the recess 5, and between the side surface 41c of the base portion 41 and the side surface 5b of the recess 5). In this state, the first water-sealing component 322i is in liquid-tight contact with the mounting surface D over its entire length in the direction of extension (i.e., over the entire water-sealing path). This prevents liquid from entering the portion of the component 322i that is on the passenger compartment side. In other words, the space between the first main body portion 321i and the door side plate portion 212 (that is, the space between the opposing surface Dt and the mounting surface D) is sealed off by the first water-sealing component 322i.
[0040] The first water-stopping component 322i is interchangeably attached to the first main body 321i. That is, the first water-stopping component 322i is manufactured as a separate, independent component from the first main body 321i and is attached to the first main body 321i to form a part of the first water-stopping member 32i. For example, during the manufacturing stage of the component, the first water-stopping component 322i may be formed into a linearly extending shape and be bent appropriately according to the water-stopping path when it is attached to the first main body 321i (i.e., when it is arranged along the water-stopping path). Alternatively, during the manufacturing stage of the component, the first water-stopping component 322i may be formed into a shape corresponding to the water-stopping path (in this case, for example, a shape in which bent portions are provided near each end in the extending direction). The mounting structure and mounting method for interchangeably attaching the first water-stopping component 322i to the first main body 321i will be described later.
[0041] <2-3. Second Water-Sealing Member> The configuration of the second water-sealing member 32j will be explained in detail. The second water-sealing member 32j comprises a main body (second main body) 321j and a water-sealing component (second water-sealing component) 322j.
[0042] (a) Second main body 321j The second main body 321j comprises a cylindrical body 61. The cylindrical body 61 is formed of, for example, an elastic material (for example, rubber (EPDM as one example), elastomer, etc.). Specifically, the cylindrical body 61 comprises, for example, an enlarged diameter cylindrical portion 611, a constricted portion 612, and a protruding portion 613. The enlarged diameter cylindrical portion 611 is cylindrical, connected to the cylindrical portion 31 at one end, and expands in diameter as it moves away from the cylindrical portion 31. The outer diameter of the enlarged side of the enlarged diameter cylindrical portion 611 is larger than the diameter of the mounting hole H1. The constricted portion 612 is cylindrical, connected to the enlarged diameter cylindrical portion 611 at one end. The outer diameter of the constricted portion 612 is smaller than the outer diameter of the enlarged end of the enlarged diameter cylindrical portion 611, and slightly smaller than the diameter of the mounting hole H1. The protruding portion 613 is annular in shape and connects to the constricted portion 612 on its inner edge. The outer diameter of the protruding portion 613 is larger than the diameter of the mounting hole H1.
[0043] The second main body portion 321j is attached to the mounting hole H1 by locking the cylindrical body 61 to the mounting hole H1. When attaching the second main body portion 321j to the mounting hole H1, specifically, for example, the protruding portion 613 is pushed into the mounting hole H1 from the side of the rear surface 11b of the body side plate portion 11. Then, while elastically deforming, the protruding portion 613 passes through the mounting hole H1 and elastically returns on the side of the front surface 11a of the body side plate portion 11. As a result, the protruding portion 613 protrudes outward in the radial direction of the mounting hole H1 and is locked to the front surface 11a of the body side plate portion 11. In this state, the constricted portion 612 is disposed inside the mounting hole H1, and the diameter-expanded cylindrical portion 611 protrudes outward in the radial direction of the mounting hole H1 and is locked to the rear surface 11b of the body side plate portion 11. That is, the cylindrical body 61 is locked so as not to fall out from the mounting hole H1 in the front and rear directions. Thereby, the second main body portion 321j is attached to the mounting hole H1. The wiring member W is drawn out from the inside of the body 1 through the mounting hole H1 by being inserted through the inside of the cylindrical body 61 locked to the mounting hole H1, and further, is routed to the side of the door side plate portion 212 by being inserted through the inside of the cylindrical portion 31. That is, the wiring member W is routed along a path passing through the mounting hole H1 and penetrating the body side plate portion 11 while being protected and waterproofed by the second water stop member 32j.
[0044] As described above, the second main body portion 321j (and thus, the second water stop member 32j) is attached to the mounting hole H1 provided in the body side plate portion 11. Here too, in the vehicle 100, the surface to which the second main body portion 321j is attached is referred to as the "attachment target surface D". Also, the surface of the second main body portion 321j, which is disposed to face the attachment target surface D in a state where the second main body portion 321j is attached to the vehicle 100, is referred to as the "opposing surface Dt". Here, for example, the attachment target surface D is the front surface 11a of the body side plate portion 11, and the opposing surface Dt is the rear surface 613b of the protruding portion 613.
[0045] (b) Second water-stopping component 322j The second water-stopping component (lip) 322j is a long member and is arranged along a defined path (water-stopping path) specified on the opposing surface Dt. The water-stopping path is, for example, a path that surrounds the mounting hole H1 when the second main body 321j is attached to the mounting hole H1. Here, the rear surface 613b, which is the opposing surface Dt, is annular in shape, and when the second main body 321j is attached to the mounting hole H1, the rear surface 613b surrounds the periphery of the mounting hole H1. In this case, the water-stopping path is, for example, an annular path that extends around the entire circumference of the rear surface 613b.
[0046] As described above, when the second main body portion 321j is attached to the mounting hole H1, the opposing surface Dt faces the mounting surface D. In this state, the elongated second water-stopping component 322j, which is arranged along the water-stopping path defined on the opposing surface Dt, is interposed between the opposing surface Dt and the mounting surface D (specifically, between the rear surface 613b of the protruding portion 613 and the front surface 11a of the body side plate portion 11). Also in this state, the second water-stopping component 322j is in liquid-tight contact with the mounting surface D over its entire length in the direction of extension (i.e., over the entire water-stopping path). This prevents liquid from entering the interior of the body 1 through the mounting hole H1. In other words, the space between the second main body portion 321j and the body side plate portion 11 (i.e., between the opposing surface Dt and the mounting surface D) is sealed by the second water-stopping component 322j.
[0047] The second water stop component 322j is detachably attached to the second main body part 321j. That is, the second water stop component 322j, like the first water stop component 322i, is manufactured as a separate and independent component from the second main body part 321j, and is attached to the second main body part 321j to form a part of the second water stop member 32j. The second water stop component 322j may be formed, for example, at the component manufacturing stage, into a shape corresponding to the water stop path (here, for example, an annular shape). Alternatively, the second water stop component 322j may be formed into a shape extending linearly at the component manufacturing stage, and may be appropriately bent according to the water stop path when attached to the second main body part 321j (for example, bent into an annular shape and both ends may be adhered as necessary). The mounting structure and mounting mode for detachably attaching the second water stop component 322j to the second main body part 321j will be described later.
[0048] <3. Mounting Structure and Mounting Mode> As described above, in the first water stop member 32i, the first water stop component 322i is detachably attached to the first main body part 321i. Similarly, in the second water stop member 32j, the second water stop component 322j is detachably attached to the second main body part 321j. In the following, when the first water stop member 32i and the second water stop member 32j are not distinguished, they are simply referred to as the "water stop member 32". Also, when the first main body part 321i and the second main body part 321j are not distinguished, they are simply referred to as the "main body part 321", and when the first water stop component 322i and the second water stop component 322j are not distinguished, they are simply referred to as the "water stop component 322".
[0049] Regarding the mounting structure and mounting mode for detachably attaching the water stop component 322 to the main body part 321, in addition to FIGS. 1 to 4, reference will be made to FIGS. 5 and 6 for explanation. FIG. 5 is a perspective view schematically showing a state where the water stop component 322 is removed from the main body part 321. FIG. 6 is a diagram for explaining the mode of replacing the water stop component 322.
[0050] (Mounting Structure) Regarding the mounting structure, the water stop member 32 includes a connecting part 101, a sealing part 102, and a groove 103. The connecting part 101 and the sealing part 102 are provided on the water stop component 322. The groove 103 is provided on the main body part 321.
[0051] The connecting portion 101 is a long, elongated member. The length of the connecting portion 101 in the extending direction is, for example, a dimension corresponding to the length of the watertight path. The connecting portion 101 has a cross-section in the width direction (a direction perpendicular to the extending direction) that is, for example, rectangular (here, for example, a flattened rectangle). That is, the connecting portion 101 has a pair of main surfaces (front surface 101a and back surface 101b) and a pair of side surfaces 101c, 101c that extend in the elongated direction. The connecting portion 101 is formed of, for example, an elastic material (for example, rubber (EPDM as one example), elastomer, etc.).
[0052] The sealing portion 102 is provided on the surface 101a of the connecting portion 101, extending over its entire length in its extending direction. The sealing portion 102 is, for example, a projection that protrudes from the surface 101a of the connecting portion 101 and extends along the length of the surface 101a. The width dimension of the sealing portion 102 (the direction perpendicular to the length direction) is smaller than the width dimension of the connecting portion 101 (here, the width dimension of the surface 101a). Preferably, the sealing portion 102 is provided in the center of the width direction of the surface 101a. As an example, the sealing portion 102 has an arc-shaped curve along the width direction. That is, the cross-section of the sealing portion 102 in the width direction is defined by a circular arc and a chord connecting its two ends. The sealing portion 102 is formed of, for example, an elastic material (e.g., rubber (EPDM as an example), elastomer, etc.). The material used to form the sealing portion 102 may be the same as or different from the material used to form the connecting portion 101. The sealing portion 102 may be formed integrally with the connecting portion 101, or it may be formed separately from the connecting portion 101 and bonded to the connecting portion 101 (for example, by using an adhesive).
[0053] The groove 103 is provided on the opposing surface Dt. Specifically, the groove 103 is provided along a watertight path defined on the opposing surface Dt. The width dimension of the groove 103 (in the direction perpendicular to the extension direction) is the same as the width dimension of the connecting portion 101. Furthermore, the width cross-section of the groove 103 has a shape corresponding to the width cross-section of the connecting portion 101 (for example, a congruent shape). For example, if the width cross-section of the connecting portion 101 is a flattened rectangle, the width cross-section of the groove 103 is also a flattened rectangle.
[0054] (Installation Method) The water-stopping component 322 is removably attached to the main body 321 by being detachably fitted into the groove 103. When attaching the water-stopping component 322 to the main body 321, for example, an operator pushes the connecting portion 101 into the groove 103 from the back surface 101b side, thereby fitting the connecting portion 101 into the groove 103. When the connecting portion 101 is fitted into the groove 103, it is held in place by elastic force, pressing against the inner wall of the groove 103 to prevent it from falling out of the groove 103. By fitting the connecting portion 101 into the groove 103 along its entire length in the direction of extension (i.e., fitting the connecting portion 101 along the entire length in the direction of extension of the groove 103), the water-stopping component 322 is arranged along the entire water-stopping path. In this way, the water-stopping component 322 is attached to the main body 321.
[0055] With the water-stopping component 322 attached to the main body 321, the surface 101a of the connecting portion 101 is exposed from the groove 103, and the seal portion 102 provided on the surface 101a protrudes from the opposing surface Dt. With the water-stopping component 322 attached to the main body 321 (Figure 4), and with the main body 321 further attached to the door side plate portion 212 or the body side plate portion 11 (specifically, the mounting hole H1 provided in the body side plate portion 11) (Figure 3), the seal portion 102 protruding from the opposing surface Dt makes liquid-tight contact with the mounting surface D over its entire length in the direction of extension (i.e., over the entire water-stopping path). As a result, water is sealed between the opposing surface Dt and the mounting surface D.
[0056] When replacing the water-sealing part 322, first, the main body 321, which is attached to the door side panel 212 or the body side panel 11, is removed from the door side panel 212 or the body side panel 11. Then, for example, a worker pulls out the connection part 101 of the existing water-sealing part 322(1) attached to the main body 321 from the groove 103. This removes the existing water-sealing part 322(1) from the main body 321 (upper part of Figure 6). Next, for example, a worker inserts the connection part 101 of the new water-sealing part 322(2) into the groove 103. This attaches the new water-sealing part 322(2) to the main body 321 (lower part of Figure 6). In this way, the existing water-sealing part 322(1) can be replaced with a new water-sealing part 322(2). For example, if the seal portion 102 of the existing water-sealing component 322(1) deteriorates due to prolonged use, the water-sealing performance can be restored by simply replacing the existing water-sealing component 322(1) with a new water-sealing component 322(2), without having to replace the entire grommet 3. In other words, water-sealing performance can be easily maintained.
[0057] The water-sealing component 322 may be replaced at an appropriate time. For example, the water-sealing component 322 may be replaced when a predetermined period of use has elapsed. Alternatively, for example, when equipment mounted on the vehicle 100 is replaced or changed, when various inspections are performed, or when the door 2 is removed for replacement or repair, the water-sealing component 322 may be replaced when the grommet 3 is removed from the vehicle 100. The timing of replacement for the first water-sealing component 322i and the timing of replacement for the second water-sealing component 322j may be the same or different. For example, if the grommet 3 is removed from the door 2 but not from the body 1, only the first water-sealing component 322i can be replaced. In other words, the first water-sealing component 322i can be replaced without removing the grommet 3 from the body 1. Similarly, if the grommet 3 is removed from the body 1 but not from the door 2, only the second water-sealing component 322j can be replaced. In other words, the second water-sealing part 322j can be replaced without having to remove the grommet 3 from the door 2.
[0058] <4. Effects> The water-stopping member 32 configured as described above comprises a main body portion 321 having an opposing surface Dt positioned opposite the mounting surface D of the vehicle 100, and a long water-stopping component 322 interposed between the mounting surface D and the opposing surface Dt. The water-stopping component 322 is replaceable and can be attached to the main body portion 321. Therefore, the water-stopping performance can be easily maintained by replacing the water-stopping component 322.
[0059] Furthermore, in the water-stopping member 32, the main body portion 321 is provided with a groove 103 along a water-stopping path defined on the opposing surface Dt. The water-stopping component 322 is detachably fitted into the groove 103. Therefore, the water-stopping component 322 can be replaced by pulling out the existing water-stopping component 322(1) from the groove 103 of the main body portion 321 and fitting a new water-stopping component 322(2) into the groove 103.
[0060] Furthermore, in the water-stopping member 32, the water-stopping component 322 comprises a long connecting portion 101 that is fitted into the groove 103, and a sealing portion 102 that protrudes from the surface 101a of the connecting portion 101 (i.e., the surface 101a that is exposed from the groove 103 when the connecting portion 101 is fitted into the groove 103) and extends along the extending direction of the surface 101a. In the width direction intersecting the extending direction, the dimensions of the sealing portion 102 are smaller than the dimensions of the connecting portion 101. With this configuration, the water-stopping component 322 is stably attached to the main body 321 because the connecting portion 101, which is wider than the sealing portion 102, is fitted into the groove 103. In addition, because the sealing portion 102 that contacts the mounting surface D is narrower than the connecting portion 101, the surface pressure between the sealing portion 102 and the mounting surface D is increased, and sufficient water-stopping performance can be achieved.
[0061] Furthermore, the first water-sealing member 32i is the portion of the grommet 3 that guides the wiring member W along the panel 21 of the door 2 of the vehicle 100, and is attached to the door 2. Therefore, the water-sealing performance can be easily maintained by replacing only the first water-sealing part 322i, without having to replace the entire grommet 3.
[0062] Furthermore, the second water-sealing member 32j is the part of the grommet 3 that is attached to the mounting hole H1, which is provided in the vehicle 100 and through which the wiring member W is guided. Therefore, the water-sealing performance can be easily maintained by replacing only the second water-sealing part 322j, without having to replace the entire grommet 3.
[0063] [Embodiment 2] The water-stopping member 32a according to Embodiment 2 comprises a main body portion 321a and a water-stopping component 322a that is replaceably attached to the main body portion 321a, similar to the water-stopping member 32 according to Embodiment 1. The water-stopping member 32a differs from Embodiment 1 in terms of the mounting structure and mounting manner for replacing the water-stopping component 322a with respect to the main body portion 321a. The mounting structure and mounting manner according to Embodiment 2 will be described with reference to Figures 7 to 9. Figure 7 is a schematic perspective view showing a grommet 3a according to Embodiment 2 (i.e., a grommet 3a comprising the water-stopping member 32a according to Embodiment 2 as the first water-stopping member 32i and the second water-stopping member 32j). Figure 8 is a schematic perspective view showing the state in which the water-stopping component 322a has been removed from the main body portion 321a. Figure 9 is a diagram for explaining how to replace the water-stopping component 322a. In the following, elements having the same configuration as those described in Embodiment 1 will be denoted by the same reference numerals and their descriptions will be omitted.
[0064] (Mounting structure) Regarding the mounting structure, the water-stopping member 32a comprises a sealing portion 201 and an adhesive portion 202. The sealing portion 201 is provided on the water-stopping component 322a. The adhesive portion 202 is provided between the main body portion 321a and the water-stopping component 322a.
[0065] The seal portion 201 is a long, elongated member. The length of the seal portion 201 in the extending direction is, for example, a dimension corresponding to the length of the watertight path. The seal portion 201 has a shape in which the cross-section in the width direction (direction perpendicular to the extending direction) is defined by an arc and a chord connecting its two ends. That is, the seal portion 201 comprises a flat surface (back surface) 201b extending in the elongated direction and a surface (curved surface) 201a that is curved in an arc along the width direction, connected to the widthwise edge of the back surface 201b. The seal portion 201 is formed of, for example, an elastic material (for example, rubber (EPDM as one example), elastomer, etc.).
[0066] The adhesive portion 202 is provided between the main body portion 321a and the water-stopping component 322a, and adheres the water-stopping component 322a to the main body portion 321a. The adhesive portion 202 can be formed using, for example, double-sided tape, adhesive, or the like. It is preferable that the adhesive portion 202 does not cause chemical or physical changes to the main body portion 321a (to the area on the main body portion 321a that the adhesive portion 202 contacts).
[0067] (Installation Method) The water-stopping component 322a is interchangeably attached to the main body 321a via the adhesive portion 202. When attaching the water-stopping component 322a to the main body 321a, first, the adhesive portion 202 is provided on the water-stopping component 322a (specifically, the back surface 201b of the seal portion 201) or the main body 321a (specifically, on the water-stopping path on the opposing surface Dt) (Figures 8 and 9 illustrate the case where the adhesive portion 202 is provided on the back surface 201b). Then, for example, a worker lays the water-stopping component 322a on the opposing surface Dt with the back surface 201b of the seal portion 201 facing the opposing surface Dt, along the water-stopping path. In this state, the adhesive portion 202 is interposed between the water-stopping component 322a and the opposing surface Dt. For example, when an operator presses the water-stopping component 322a toward the opposing surface Dt, the water-stopping component 322a is bonded to the opposing surface Dt (and consequently, to the main body 321a) via the adhesive portion 202. As the water-stopping component 322a is bonded to the opposing surface Dt along its entire length in its extending direction, the water-stopping component 322a is positioned along the entire water-stopping path. In this way, the water-stopping component 322a is attached to the main body 321a.
[0068] With the water-stopping component 322a attached to the main body 321a, the seal portion 201 protrudes from the opposing surface Dt. With the water-stopping component 322a attached to the main body 321a, and with the main body 321a further attached to the door side panel portion 212 or the body side panel portion 11, the seal portion 201 protruding from the opposing surface Dt makes liquid-tight contact with the mounting surface D over its entire length in the direction of extension (i.e., over the entire water-stopping path). As a result, water is sealed between the opposing surface Dt and the mounting surface D.
[0069] When replacing the water-sealing part 322a, first, the main body portion 321a, which is attached to the door side panel portion 212 or the body side panel portion 11, is removed from the door side panel portion 212 or the body side panel portion 11. Then, for example, a worker peels off the existing water-sealing part 322a(1), which is bonded to the main body portion 321a via the adhesive portion 202, from the main body portion 321a. Before this work, a chemical solution that reduces the adhesive strength of the adhesive portion 202 may be applied in advance. This removes the existing water-sealing part 322a(1) from the main body portion 321a (upper part of Figure 9). Subsequently, the new water-sealing part 322a(2) is bonded to the main body portion 321a via the adhesive portion 202. This attaches the new water-sealing part 322a(2) to the main body portion 321a (lower part of Figure 9). In this way, the existing water-stopping component 322a(1) can be replaced with a new water-stopping component 322a(2).
[0070] The water-stopping member 32a configured as described above includes an adhesive portion 202 for bonding the water-stopping component 322a to the main body portion 321a. Therefore, the water-stopping component 322 can be replaced by peeling off the existing water-stopping component 322a(1) that is bonded to the main body portion 321a and bonding a new water-stopping component 322a(2) to the main body portion 321a.
[0071] [Embodiment 3] The water-stopping member 32b according to Embodiment 3 comprises a main body portion 321b and a water-stopping component 322b that is replaceably attached to the main body portion 321b, similar to the water-stopping member 32 according to Embodiment 1. The water-stopping member 32b differs from Embodiments 1 and 2 in terms of the mounting structure and mounting manner for replacing the water-stopping component 322b with respect to the main body portion 321b. The mounting structure and mounting manner according to Embodiment 3 will be described with reference to Figures 10 to 12. Figure 10 is a schematic perspective view showing a grommet 3b according to Embodiment 3 (i.e., a grommet 3b comprising the water-stopping member 32b according to Embodiment 3 as the first water-stopping member 32i and the second water-stopping member 32j). Figure 11 is a schematic perspective view showing the state in which the water-stopping component 322b has been removed from the main body portion 321b. Figure 12 is a diagram for explaining how to replace the water-stopping component 322b. In the following descriptions, elements with the same configuration as those described in Embodiments 1 and 2 will be denoted by the same reference numerals and their descriptions will be omitted.
[0072] (Mounting Structure) Regarding the mounting structure, the water-stopping member 32b comprises a base portion 301, a sealing portion 302, a locking portion 303, and a locked portion 304. The base portion 301 and the sealing portion 302 are provided on the water-stopping component 322b. One of the locking portion 303 and the locked portion 304 is provided on the water-stopping component 322b, and the other is provided on the main body portion 321b. Here, for example, the locking portion 303 is provided on the water-stopping component 322b, and the locked portion 304 is provided on the main body portion 321b.
[0073] The base portion 301 is a long, rectangular member. The length of the base portion 301 in the extending direction is, for example, a dimension corresponding to the length of the water-stopping path. The base portion 301 has a cross-section in the width direction (a direction perpendicular to the extending direction) that is, for example, rectangular (here, for example, a flattened rectangle). That is, the base portion 301 has a pair of main surfaces (front surface 301a and back surface 301b) and a pair of side surfaces 301c, 301c that extend in the longitudinal direction. The base portion 301 is formed of, for example, an elastic material (for example, rubber (EPDM as one example), elastomer, etc.).
[0074] The seal portion 302 is provided on the surface 301a of the base portion 301, extending along its entire length in the direction of extension. The seal portion 302 is, for example, a projection that protrudes from the surface 301a of the base portion 301 and extends along the direction of extension of the surface 301a. The width dimension of the seal portion 302 (the direction perpendicular to the direction of extension) is smaller than the width dimension of the base portion 301 (here, the width dimension of the surface 301a). Preferably, the seal portion 302 is provided in the center of the width direction of the surface 301a. As an example, the seal portion 302 has a shape that curves in an arc along the width direction. That is, the cross-section of the seal portion 302 in the width direction is defined by a circular arc and a chord connecting its two ends. The seal portion 302 is formed of, for example, an elastic material (e.g., rubber (EPDM as an example), elastomer, etc.). The material used to form the seal portion 302 may be the same as the material used to form the base portion 301, or it may be different. The seal portion 302 may be formed integrally with the base portion 301, or it may be formed separately from the base portion 301 and bonded to the base portion 301 (for example, by using an adhesive).
[0075] The locking portion 303 is provided, for example, on the water-stopping component 322b. Specifically, for example, multiple locking portions 303 are arranged on the back surface 301b of the base portion 301, spaced apart along its extending direction. The number and placement of the locking portions 303 can be determined as appropriate. If the base portion 301 has an end, it is preferable that the locking portions 303 are provided at least at each end of the base portion 301 in its extending direction.
[0076] The locking portion 303 includes, for example, a projection 71. Specifically, the projection 71 includes, for example, a shaft 711 and a locking piece 712. The shaft 711 is, for example, rod-shaped, and is fixed to the base portion 301 by having its axial tip protrude from the back surface 301b of the base portion 301, while its axial base end is embedded in the base portion 301. The portion of the shaft 711 embedded in the base portion 301 may also preferably be formed in a flange shape. The locking piece 712 is, for example, an elongated member, fixed to the tip of the shaft 711 at its center in the longitudinal direction, and protruding outward from the shaft 711 at both ends. As an example, the portion of the locking piece 712 that protrudes outward from the shaft 711 extends away from the shaft 711 from the tip to the base end, and is configured to be elastically deformable in a direction approaching the shaft 711. The shaft 711 and the locking piece 712 are preferably formed from a material with higher rigidity than the base portion 301 (for example, metal, resin, etc.).
[0077] The locking portion 304 is provided, for example, on the main body portion 321b. Specifically, for example, multiple locking portions 304 are arranged at intervals along a water-stopping path defined on the opposing surface Dt. Each locking portion 304 is provided at a position (hereinafter referred to as the "locking position") that corresponds to the locking portion 303 when the water-stopping component 322b is arranged along the water-stopping path.
[0078] The locking portion 304 includes, for example, a hole 72. The hole 72 is provided at the locking position on the opposing surface Dt. In the first main body portion 321i, the opposing surface Dt is the rear surface 41b or side surface 41c of the base portion 41. In this case, the hole 72 is, for example, a through hole that penetrates the rear wall portion or side wall portion of the base portion 41 in the thickness direction. In the second main body portion 321j, the opposing surface Dt is the rear surface 613b of the protruding portion 613. In this case, the hole 72 is, for example, a through hole that penetrates the protruding portion 613 in the thickness direction.
[0079] The locking portion 304 is preferably provided with a reinforcing plate 73. The reinforcing plate 73 is a plate-shaped member and is provided at the locking position on the opposing surface Dt. As described above, in the first main body portion 321i, the opposing surface Dt is the rear surface 41b or side surface 41c of the base portion 41. In this case, a recess is provided on the rear surface 41b or side surface 41c of the base portion 41, and the reinforcing plate 73 is disposed therein. Also, as described above, in the second main body portion 321j, the opposing surface Dt is the rear surface 613b of the overhang portion 613. In this case, a recess is provided on the rear surface 613b of the overhang portion 613, and the reinforcing plate 73 is disposed therein. The reinforcing plate 73 is made of a material (for example, metal, resin, etc.) that has higher rigidity than the member on which it is disposed (i.e., the portion that forms the recess on which the reinforcing plate 73 is disposed). In other words, when a reinforcing plate 73 is provided, the base portion 41 or the protruding portion 613 will consist of a first portion (i.e., the portion that forms the recess where the reinforcing plate 73 is disposed) and a second portion (i.e., the reinforcing plate 73) which has higher rigidity than the first portion. When a reinforcing plate 73 is provided, the hole 72 is provided in the reinforcing plate 73. Specifically, for example, the hole 72 is provided penetrating the reinforcing plate 73 in the thickness direction. By providing the hole 72 in the relatively rigid reinforcing plate 73, the hole 72 becomes less prone to deformation.
[0080] (Mounting method) The water-stopping component 322b is removably attached to the main body 321b by the locking portion 303 being detachably locked to the locked portion 304. When attaching the water-stopping component 322b to the main body 321b, for example, an operator locks each locking portion 303 provided on the water-stopping component 322b to each locked portion 304 (corresponding locked portion 304) provided on the water-stopping path of the main body 321b. Specifically, for example, an operator inserts (pushes) the projection 71 into the hole 72 along the extending direction of the shaft 711. Then, the locking piece 712 is inserted through the hole 72 while elastically deforming to approach the shaft 711, and after exiting the hole 72, it elastically returns to its original shape, protruding radially outward from the hole 72 and locking into the hole 72 (a locking structure is formed). All of the locking portions 303 provided on the water-stopping component 322b are locked to the corresponding locked portions 304, thereby providing the water-stopping component 322b throughout the entire water-stopping path. In this way, the water-stopping component 322b is attached to the main body portion 321b.
[0081] With the water-stopping component 322b attached to the main body 321b, the seal portion 302 protrudes from the opposing surface Dt. With the water-stopping component 322b attached to the main body 321b, and with the main body 321b further attached to the door side panel portion 212 or the body side panel portion 11, the seal portion 302 protruding from the opposing surface Dt makes liquid-tight contact with the mounting surface D over its entire length in the direction of extension (i.e., over the entire water-stopping path). As a result, water is sealed between the opposing surface Dt and the mounting surface D.
[0082] When replacing the water-sealing part 322b, first, the main body 321b, which is attached to the door side panel portion 212 or the body side panel portion 11, is removed from the door side panel portion 212 or the body side panel portion 11. Then, the existing water-sealing part 322b(1) attached to the main body portion 321b is removed from the main body portion 321b (upper part of Figure 12). When removing the existing water-sealing part 322b(1) from the main body portion 321b, the worker releases the locking between each locking portion 303 provided on the existing water-sealing part 322b(1) and each locked portion 304 provided on the main body portion 321b. Specifically, for example, the worker pulls the projection 71 away from the hole portion 72 along the extending direction of the shaft 711. Then, under the pulling force on the projection 71, for example, the locking piece 712 is broken off and separated from the shaft 711, and the projection 71 is pulled out of the hole 72. Alternatively, the worker may pull the projection 71 out of the hole 72 by applying a force that deforms the locking piece 712 toward the shaft 711 while pulling the projection 71 toward the hole 72. All the locking parts 303 provided on the existing water-stopping part 322b(1) are released from the locking parts 304, and the existing water-stopping part 322b(1) is removed from the main body 321b. Subsequently, the new water-stopping part 322b(2) is attached to the main body 321b (lower part of Figure 12). When attaching the new water-stopping part 322b(2) to the main body 321b, as described above, the worker engages each locking portion 303 provided on the new water-stopping part 322b(2) with each locking portion 304 provided on the main body 321b. In this way, the existing water-stopping part 322b(1) can be replaced with the new water-stopping part 322b(2).
[0083] The water-stopping member 32b configured as described above includes a locking portion 303 provided on one of the water-stopping component 322b and the main body portion 321b, and a locked portion 304 provided on the other of the water-stopping component 322b and the main body portion 321b. The locking portion 303 is detachably locked to the locked portion 304. With this configuration, the water-stopping component 322b can be replaced by releasing the locking between the locking portion 303 provided on one of the main body portion 321b and the locked portion 304 provided on the other of the existing water-stopping component 322b(1), removing the existing water-stopping component 322b(1) from the main body portion 321b, and then attaching the new water-stopping component 322b(2) to the main body portion 321b by locking the locking portion 303 provided on one of the main body portion 322b(2) and the locked portion 304 provided on the other of the new water-stopping component 322b(2).
[0084] Furthermore, in the water-stopping member 32b, the locking portion 303 is provided with a projection 71, and the locked portion 304 is provided with a hole 72. The projection 71 is inserted into the hole 72 and locked into the hole 72. With this configuration, the locking portion 303 can be easily locked into the locked portion 304.
[0085] Furthermore, in the case where the water-stopping member 32b is provided with a reinforcing plate 73 and a hole 72 in the member to which the locking portion 304 is provided (for example, the main body portion 321b), that is, the main body portion 321b comprises a first portion (a portion that forms a recess in which the reinforcing plate 73 is disposed) and a second portion (reinforcing plate 73) which has higher rigidity than the first portion, and the hole 72 is provided in the second portion, the hole 72 is less likely to deform because it is provided in the second portion which has higher rigidity than the first portion, and the projection 71 is stably locked.
[0086] [Modifications] In embodiments 1, 2, and 3, the water-sealing path defined on the opposing surface Dt may be any type. For example, as in the grommet 3c illustrated in Figure 13, when a rear opening H3c is provided near the center of the rear surface 41b of the base portion 41, a water-sealing path that bypasses it may be defined. That is, the first water-sealing component 322i may be arranged along a water-sealing path that bypasses the rear opening H3c. Specifically, a water-sealing path that bypasses the rear opening H3c is, for example, a path that extends along the edge near the arc-shaped bulge of the rear surface 41b of the base portion 41, and faces the side surface 41c of the base portion 41 at each end in the direction of extension. In the grommet shown in Figure 13, the wiring member W may be pulled out through an opening facing the vehicle compartment, similar to embodiment 1.
[0087] The configuration of the water-stopping member 32 according to Embodiment 1 can be modified as appropriate. For example, the connecting portion 101 may be omitted. That is, the sealing portion 102 may be detachably fitted into the groove 103. Also, for example, the connecting portion 101 may have a polygonal cross-section, or its cross-section may include non-linear portions (for example, arc-shaped portions, wavy portions). Also, for example, the sealing portion 102 may have a rectangular cross-section, or its cross-section may have a polygonal cross-section. Also, for example, a plurality of sealing portions 102 may be provided on the surface 101a of the connecting portion 101. Also, for example, an adhesive portion or a locking structure may be provided between the connecting portion 101 and the groove 103 into which it is fitted.
[0088] The configuration of the water-stopping member 32a according to Embodiment 2 can be modified as appropriate. For example, the seal portion 201 may have a rectangular cross-section or a polygonal cross-section. Also, for example, in the water-stopping component 322a, the seal portion 201 may be provided on a connecting portion that has a larger width dimension than the seal portion 201, and an adhesive portion 202 may be provided between this connecting portion and the main body portion 321a. Also, for example, in order to simplify the work of laying the water-stopping component 322a along the water-stopping path, the main body portion 321a may be provided with grooves (grooves along the water-stopping path), marks (for example, marks indicating the end position, intermediate position, etc. of the water-stopping path), guide-shaped portions (for example, recesses or protrusions indicating the position, extending direction, etc. of the water-stopping path), positioning-shaped portions (for example, protrusions that can position the water-stopping component 322a at a position on the water-stopping path), etc.
[0089] The configuration of the water-stopping member 32b according to Embodiment 3 can be modified as appropriate. For example, the base portion 301 may be omitted. That is, a locking portion 303 or a locked portion 304 may be provided on the seal portion 302. Also, for example, the base portion 301 may have a polygonal cross-section, or a cross-section that includes non-linear portions (for example, arc-shaped portions, wavy portions). Also, for example, the seal portion 302 may have a rectangular cross-section, or a polygonal cross-section. Also, for example, a plurality of seal portions 302 may be provided on the surface 301a of the base portion 301. Also, for example, a locking portion 303 (specifically, for example, a projection 71) may be provided on the main body portion 321b, and a locked portion 304 (specifically, for example, a hole 72 and a reinforcing plate 73) may be provided on the water-stopping component 322b. When a reinforcing plate 73 is provided on the water-stopping component 322b, for example, a recess is provided on the back surface 301b of the base portion 301, and the reinforcing plate 73 is disposed therein. In this case, the water-stopping component 322b will consist of a first portion (i.e., the portion that forms the recess where the reinforcing plate 73 is disposed) and a second portion (i.e., the reinforcing plate 73) which has higher rigidity than the first portion. Needless to say, when a reinforcing plate 73 is provided, the hole 72 is provided in the reinforcing plate 73. Also, the locking portion 303 and the locked portion 304 do not necessarily have to be a combination of a projection 71 and a hole 72. Furthermore, the reinforcing plate 73 may be provided not only at the locked position but also along the entire water-stopping path. Also, the reinforcing plate 73 is not essential and may be omitted.
[0090] In each of the embodiments 1, 2, and 3 described above, the forming materials for the water-stopping parts 322, 322a, and 322b, and the forming materials for the main body parts 321, 321a, and 321b can all be appropriately selected. For example, a foamed material (e.g., foamed resin) may be used as the forming material for the water-stopping parts 322, 322a, and 322b. In this case, it is preferable that the foamed material has closed cells. Furthermore, the forming materials for the water-stopping parts 322, 322a, and 322b and the forming materials for the main body parts 321, 321a, and 321b may be the same or different. Since the water-stopping parts 322, 322a, and 322b and the main body parts 321, 321a, and 321b are separate and independent parts, the forming material for the other can be selected without being restricted by the forming material of the other.
[0091] In each of the above embodiments, the grommets 3, 3a, and 3b do not necessarily need to include both the first water-sealing member 32i and the second water-sealing member 32j. For example, the grommets 3, 3a, and 3b may include the first water-sealing member 32i as the part attached to the door 2, and a different member from the second water-sealing member 32j as the part attached to the body 1. Alternatively, for example, the grommets 3, 3a, and 3b may include the second water-sealing member 32j as the part attached to the body 1, and a different member from the first water-sealing member 32i as the part attached to the door 2.
[0092] In each of the embodiments 1, 2, and 3 described above, the grommets 3, 3a, and 3b do not necessarily have to be through-hole grommets. For example, the grommets 3, 3a, and 3b may be grommets that guide the wiring member W through a through-hole provided in the panel 21 of the door 2 (for example, the door side plate portion 212). In this case, the grommet may be equipped with a second water-sealing member 32j according to each of the embodiments 1, 2, and 3 described above as a water-sealing member attached to the through-hole. Furthermore, the water-sealing members 32, 32a, and 32b may be provided on parts other than the grommets 3, 3a, and 3b.
[0093] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other.
