[0009] [Explanation of Embodiments of this Disclosure] First, the embodiments of this disclosure will be listed and explained.

[0010] The wiring retaining components of this disclosure are as follows:

[0011] (1) A wiring retaining component for supporting a wiring member in a state along the surface of a panel to be mounted on a vehicle, comprising: a cylindrical portion through which the wiring member passes; and a wiring member retaining portion that keeps the portion of the wiring member extending from one end of the cylindrical portion in a state along the surface, wherein the wiring member retaining portion includes a fixing portion that is fixed to the panel to be mounted, the fixing portion has a fastening portion that is fastened and fixed to the panel to be mounted, and a portion that is easily broken is formed in the wiring member retaining portion at a position between the cylindrical portion and the fastening portion.

[0012] With this wiring retaining component, the wiring member retaining portion separates at the easily breakable portion. Therefore, the part of the wiring member retaining portion that holds the wiring member can be separated from the fastening portion. This allows the wiring member to be easily removed from the panel to which it is attached.

[0013] (2) Like the wiring retaining component of (1), the wiring member retaining portion includes an overhang extending outward from one end of the cylindrical portion, at least a part of the overhang is the fixing portion, and the easily breakable portion may be formed in the overhang.

[0014] In this case, if at least a portion of the protruding part is a fixed part, it is easier to separate the part of the wiring member holding section that holds the wiring member from the cylindrical part by cutting the protruding part.

[0015] (3) The wiring retaining component of (2), wherein the wiring member retaining portion includes an overhang extending outward from one end of the cylindrical portion, the fixing portion is separate from the overhang, the fixing portion has a pressing portion that presses against the outward surface of the overhang, the fastening portion extends from the pressing portion to an area outside the overhang, and the easily breakable portion may be formed in the fixing portion.

[0016] In this case, the fixing portion breaks at the easily breakable portion, releasing the pressure on the protruding portion. This allows the protruding portion and the cylindrical portion to be easily removed from the panel to which they are attached.

[0017] (4) The wiring retaining component of (3), wherein the fastening portion has a first fastening portion and a second fastening portion, and the retaining portion may be located between the first fastening portion and the second fastening portion.

[0018] This allows the retaining portion between the first and second fastening portions to firmly hold the protruding portion. As a result, the protruding portion is securely fixed to the panel to which it is attached.

[0019] (5) A wiring retaining component according to any one of (1) to (4), wherein the easily breakable portion may include a thin-walled portion.

[0020] This makes it easier to break the wiring component holder at the thin, easily breakable section.

[0021] (6) A wiring retaining component according to any one of (1) to (5), wherein the wiring member retaining portion includes a metal portion, and the easily breakable portion may be formed by forming a thin-walled portion on the metal portion.

[0022] Even if the wiring component holder includes a metal part, making the metal part thin creates a section that is prone to breaking, making that section more likely to break.

[0023] [Details of Embodiments of the Disclosure] Specific examples of the wiring retention components of the Disclosure are 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.

[0024] [Embodiment 1] The wiring retaining component according to Embodiment 1 will be described below. The wiring retaining component supports the wiring member in a state that is aligned with the surface of the mounting panel of the vehicle. The wiring retaining component does not allow the wiring member to penetrate the mounting panel, but rather aligns it with the surface of the mounting panel. In this embodiment, an example will be described in which the mounting panel is the door 10 of the vehicle.

[0025] Figure 1 is a perspective view showing the wiring retaining component 20 attached to the door 10. Figure 2 is a perspective view showing the wiring retaining component 20 before attachment to the door 10. Figure 3 is a perspective view showing the wiring retaining component 20. Figure 4 is an exploded perspective view showing the wiring retaining component 20.

[0026] <About the Doors> Door 10 is provided to open and close a door opening provided in the body. Door 10 may be a side door (driver's side door, passenger side door, or rear passenger side door) or a back door. Door 10 is connected to the body, for example, via a hinge (not shown), and rotates around the hinge to close or open the door opening.

[0027] The door 10 includes a panel 12. The panel 12 is made of, for example, metal (sheet metal, for instance) and serves as the framework of the door 10. The panel 12 includes, for example, an outer panel 13 and an inner panel 14. The outer panel 13, together with the body, constitutes the exterior appearance of the vehicle. The inner panel 14 is located on the passenger compartment side of the outer panel 13. A door trim (not shown) is attached to the inner panel 14. The door trim is an interior component that constitutes the interior design of the door 10 and is made of, for example, resin. The inner panel 14 includes an inner panel portion (door inner panel portion) 15 and a side panel portion (door side panel portion) 16. The door inner panel portion 15 is positioned with a gap between it and the outer panel 13, and is located on the passenger compartment side of the outer panel 13 when the door 10 is closed. The door side panel portion 16 extends from the edge of the door inner panel portion 15 toward the outer panel 13. When the door 10 is closed, the door side panel portion 16 faces the door opening on the body side. The inner panel 14 comprises a door inner panel portion 15 and a door side panel portion 16, creating a space between the outer panel 13 and the inner panel 14. Various devices are housed in this space. These devices include, for example, at least one of a door lock actuator, a window opening and closing actuator, and a door switch.

[0028] A weatherstrip 19 is attached to the door 10, separating the interior and exterior of the vehicle. The weatherstrip 19 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 16. As will be described later, a wiring retaining component 20 is attached to the door side panel 16, and the weatherstrip 19 is installed over the wiring retaining component 20, overlapping it and crossing it. When the door 10 is closed, the weatherstrip 19 contacts the periphery of the door opening of the body, preventing liquid from entering the portion of the body on the interior side of the weatherstrip 19.

[0029] A recess 17 is formed in the portion of the door side panel 16 where the wiring retaining component 20 is attached. The recess 17 forms a space that is recessed inward in the thickness direction from the surface of the door side panel 16. The recess 17 opens outward in the thickness direction of the door side panel 16. The recess 17 also opens on the passenger compartment side of the door side panel 16. The recess 17 is surrounded by the door side panel 16 on the top, bottom, and exterior sides. For example, the recess 17 may be a recess defined by a bottom surface 17a and slopes 17b extending above, below, and to the exterior of the bottom surface 17a.

[0030] In this embodiment, the panel to be mounted is the door side panel portion 16.

[0031] <About the wiring retention component> The wiring retention component 20 supports the wiring member W in a state that is aligned with the surface of the door side panel portion 16. For example, the wiring retention component 20 holds the wiring member W in a state that is aligned with the surface of the door side panel portion 16 when fitted into the recess 17. The wiring member W is inserted into the recess 17 together with the wiring retention component 20. As a result, the amount by which the wiring member W and the wiring retention component 20 protrude from the opening of the recess 17 can be reduced. Furthermore, the weatherstrip 19, which is positioned on the door side panel portion 16, can pass continuously over the wiring retention component 20. As a result, water is prevented from entering the vehicle from the part of the wiring member that is moving from the outside to the inside of the vehicle with respect to the weatherstrip 19.

[0032] Furthermore, the wiring retaining component 20 may cover the wiring member W routed between the body and the door 10. One end of the wiring retaining component 20 may be attached to the body, and the other end may be attached to the door 10. The wiring member W may include a bundle of multiple wires. The wiring member W may be bundled together as a single unit between the body and the door 10. The wiring member W may be led into the door 10 on the passenger compartment side. It may branch inside the vehicle or inside the door 10. The wiring member W transmits power, signals, etc., for example, between equipment installed on the body and equipment installed on the door 10. The wiring member W may include an optical fiber cable.

[0033] This wiring retaining component 20 can enter the door 10 by passing over the weatherstrip towards the passenger compartment without penetrating the door side panel portion 16 of the door 10. Such a wiring retaining component 20 may also be called a through-less grommet.

[0034] In this embodiment, the wiring holding component 20 comprises an inner component 30, an elastic component 40, and an outer component 50.

[0035] The elastic component 40 is formed from, for example, an elastic material (e.g., rubber (EPDM: ethylene propylene diene rubber), elastomer, etc.). The elastic component 40 may also be a component integrally molded from an elastic material.

[0036] The elastic component 40 comprises a cylindrical portion 42 and an overhanging outer portion 46.

[0037] The cylindrical portion 42 has a cylindrical shape through which the wiring member W passes. The cylindrical portion 42 is formed, for example, in a bellows shape and is made to be deformable (for example, bendable and expandable). The door side plate portion 16 is positioned in close proximity to and opposite the peripheral edge of the door opening of the body when the door 10 is closed, and moves away from the peripheral edge of the door opening when the door 10 is opened. The cylindrical portion 42 deforms to follow this change in positional relationship.

[0038] The protruding outer casing 46 extends outward from one end of the cylindrical portion 42. The protruding outer casing 46 is formed in a shape that allows it to be fitted into the recess 17. The protruding outer casing 46 also forms a space inside through which the wiring member W can pass.

[0039] More specifically, the protruding exterior portion 46 includes a housing portion 46a having a shape corresponding to the bottom surface 17a and the inclined surface 17b of the recess 17, and a main plate-shaped portion 46b that closes the opening on the body side of the housing portion 46a. The main plate-shaped portion 46b may extend wider than the opening on the body side of the housing portion 46a. In the present embodiment, the main plate-shaped portion 46b extends in the vertical direction and outward of the vehicle with respect to the housing portion 46a.

[0040] The recess 17 may have a shallow recess that houses a portion of the main plate-shaped portion 46b that protrudes from the main plate-shaped portion 46b.

[0041] The protruding exterior portion 46 has a vehicle compartment side opening 46h that opens to the vehicle compartment side. The vehicle compartment side opening 46h is an opening elongated in the vertical direction.

[0042] The cylindrical portion 42 is continuous with the main plate-shaped portion 46b. For example, the cylindrical portion 42 is continuous with the main plate-shaped portion 46b closer to the outside of the vehicle. One end opening of the cylindrical portion 42 opens into the protruding exterior portion 46. Therefore, the wiring member W passed through the cylindrical portion 42 can pass through the protruding exterior portion 46 and go toward the vehicle compartment side from the vehicle compartment side opening 46h.

[0043] Seal protrusions 46s may be formed along the vertical direction at positions of the protruding exterior portion 46 that face the bottom surface 17a and the inclined surface 17b of the recess 17. There may be a plurality of seal protrusions 46s. When the protruding exterior portion 46 is fitted into the recess 17, the seal protrusions 46s contact the bottom surface 17a and the inclined surface to suppress the intrusion of liquid from outside the vehicle compartment into the vehicle compartment through the gap between the recess 17 and the protruding exterior portion 46.

[0044] At least a part of the inner component 30 enters the protruding exterior portion 46 and reinforces the protruding exterior portion 46 so as to maintain a certain shape. The inner component 30 is formed of a material (for example, resin or metal) having higher rigidity than the elastic component 40. The inner component 30 may be, for example, a component integrally formed by die molding with resin.

[0045] More specifically, the inner component 30 includes an overhanging reinforcement portion 34 and an additional holding portion 36.

[0046] The protruding reinforcement portion 34 is formed in a hollow shape that can enter the protruding exterior portion 46 and secure a space through which the wiring member W can pass inside. For example, the protruding reinforcement portion 34 is formed in a shape corresponding to the inner peripheral surfaces of the accommodating portion 46a and the main plate-shaped portion 46b. The protruding reinforcement portion 34 is inserted into the protruding exterior portion 46 from the vehicle interior side opening 46h. Thereby, the protruding exterior portion 46 is reinforced, and it becomes easier to maintain the shape corresponding to the bottom surface 17a and the inclined surface 17b of the recess 17. Also, it becomes easier to maintain the state where the main plate-shaped portion 46b of the protruding exterior portion 46 is arranged on the surface extension of the door side plate portion 16.

[0047] An opening 34h1 is formed on the extension of one end opening of the cylindrical portion 42 in the protruding reinforcement portion 34. A vehicle interior side opening 34h2 is formed in the portion of the protruding reinforcement portion 34 facing the vehicle interior. Therefore, the wiring member W passed through the cylindrical portion 42 can further pass through the protruding reinforcement portion 34 inside the protruding exterior portion 46 and face the vehicle interior side from the vehicle interior side opening 34h2.

[0048] The additional holding portion 36 further extends from the edge on the vehicle interior side of the protruding reinforcement portion 34. The additional holding portion 36 extends, for example, in a bent posture (for example, a right-angled bent posture) with respect to the protruding reinforcement portion 34. The additional holding portion 36 may extend along the inner panel 14, for example. The additional holding portion 36 may have a configuration including a bottom portion 36a and a pair of side wall portions 36b erected on both sides thereof.

[0049] The wiring member W coming out from the vehicle interior side opening 34h2 may be arranged along the additional holding portion 36 and guided along the inner panel 14. The wiring member W may be bound to the inner panel 14 with an adhesive tape or a binding band and held by the inner panel 14.

[0050] The outer component 50 is a portion fixed to the door side plate portion 16 as the mounting target panel.

[0051] The outer component 50 is formed as a whole to be less deformable than the protruding reinforcement portion 34. The whole of the outer component 50 may be formed of a resin having higher rigidity than an elastic component, or may be formed of metal. The outer component 50 may be a resin component into which a metal component is inserted.

[0052] The outer part 50 has fastening portions 54A and 54B that are fastened and fixed to the door side plate portion 16. The fastening portions 54A and 54B are portions that are fixed by fasteners such as screws or rivets. The fastening portions 54A and 54B are portions that have through holes 54h through which the fasteners pass.

[0053] In this embodiment, the outer part 50 has a pressing portion 52 that presses against the outward-facing surface of the protruding exterior portion 46. The position in which the pressing portion 52 presses against the outward-facing surface of the protruding exterior portion 46 is arbitrary. For example, the portion of the protruding exterior portion 46 around the base end of the cylindrical portion 42 may be pressed. In this embodiment, the pressing portion 52 is formed in an elongated shape that passes vertically through the outward-facing surface of the protruding exterior portion 46, more specifically, in an elongated rectangular parallelepiped shape. A recess 52g is formed in the middle of the longitudinal direction of the pressing portion 52, and the base end of the cylindrical portion 42 is positioned within the recess 52g. The pressing portion 52 presses against the upper and lower portions of the base end of the cylindrical portion 42 and the portion on the vehicle interior side of the outward-facing surface of the protruding exterior portion 46.

[0054] The fastening portions 54A and 54B extend from the pressing portion 52 into an area outside the protruding portion 24. In this embodiment, the outer part 50 has a first fastening portion 54A and a second fastening portion 54B as fastening portions 54A and 54B. The first fastening portion 54A extends above the pressing portion 52, and the second fastening portion 54B extends below the pressing portion 52. The pressing portion 52 is located between the first fastening portion 54A and the second fastening portion 54B.

[0055] The retaining portion 52 presses down on the outward-facing surface of the protruding exterior portion 46, while the fastening portions 54A and 54B are fastened and fixed to the door side plate portion 16 on the outside of the protruding exterior portion 46, in this case, on the upper and lower outer sides.

[0056] A portion 56 that is easily broken is formed between the cylindrical portion 42 and the fastening portion 54A. A portion 56 that is easily broken is formed between the cylindrical portion 42 and the fastening portion 54A or fastening portion 54B, and is more easily broken than the fastening portions 54A and 54B. The portion 56 that is easily broken may be, for example, a portion that is easily broken by having a smaller cross-sectional area in the part extending from the fastening portion 54A or fastening portion 54B toward the cylindrical portion 42.

[0057] In this embodiment, the easily breakable portion 56 is the portion of the outer part 50 in which a groove 56g is formed between the retaining portion 52 and the fastening portion 54A or fastening portion 54B. In other words, the easily breakable portion 56 includes a thin-walled portion 56t of the outer part 50 that is formed thinner by the groove 56g than the adjacent portion, particularly the portion on the fastening portion 54A, 54B side. The groove 56g for forming the easily breakable portion 56 may be recessed on the outward-facing surface of the outer part 50, or recessed on the upward or downward-facing surface, or recessed on the inward-facing surface. The shape of the groove for forming the easily breakable portion 56 is arbitrary. The groove may be V-shaped, U-shaped, or have a rectangular cross-section. An example of a rectangular cross-section groove 56ga is shown as a modified example in Figure 5.

[0058] The groove 56g for forming the easily breakable portion 56 may be formed overall across the outer part 50, or it may be formed intermittently.

[0059] The easily breakable portion 56 is preferably positioned so that the wiring member W can be removed from the door 10 while the fastening portions 54A and 54B remain fastened and fixed to the door side panel portion 16, and the wiring holding component 20 is broken. The easily breakable portion 56 may be formed, for example, in a position that overlaps with the outer peripheral boundary of the protruding exterior portion 46 or outside the outer peripheral boundary. In this case, the outer component 50 is divided at the two easily breakable portions 56, thereby separating the retaining portion 52 from the two fastening portions 54A and 54B (see Figure 6). The retaining force on the protruding exterior portion 46 is released, and the protruding exterior portion 46 can detach from the door side panel portion 16 by passing between the two fastening portions 54A and 54B. As a result, the wiring member W passing through the protruding exterior portion 46 can also be removed from the door side panel portion 16.

[0060] In this embodiment, the protruding exterior portion 46 of the elastic component 40, the protruding reinforcing portion 34 of the inner component 30, and the outer component 50 function as a wiring member holding portion 22 that keeps the portion of the wiring member W that extends from one end of the cylindrical portion 42 in a state that conforms to the surface of the door side plate portion 16. Furthermore, the protruding exterior portion 46 and the protruding reinforcing portion 34 inside it constitute the protruding portion 24 that extends outward from one end of the cylindrical portion 42.

[0061] The outer part 50 is an example of a fixing part 26 that is separate from the protruding part. This fixing part 26 also has a pressing part 52, fastening parts 54A and 54B extend from the pressing part 52 to the outside of the protruding part 24, and an easily breakable part 56 is formed on the outer part 50 as the fixing part.

[0062] <Example of removal procedure> An example of the procedure for removing the wiring component W from the door 10, starting from a state where the wiring component W and the wiring retaining component 20 are attached to the door 10, will be explained.

[0063] In other words, the wiring member W is attached to the door 10 by the wiring holding component 20 so as to pass through the surface of the door side panel portion 16. The fastening portions 54A and 54B of the outer component 50 are screw-fastened and fixed to the door side panel portion 16 by screws S. The protruding portion 24 is pressed against the recess 17 of the door side panel portion 16 by the retaining portion 52 of the outer component 50. The wiring member W is routed from the body through the cylindrical portion 42 and the protruding portion 24 toward the passenger compartment side of the door 10.

[0064] For example, when a vehicle is being dismantled, it may be desirable to separate the wiring member W, which has a conductor made of copper or aluminum, from the door 10. Since the dismantling work of removing screws S is complicated, it is desirable to be able to easily separate the wiring member W from the door 10.

[0065] Therefore, the wiring member W is pulled away from the door 10. For example, the cylindrical portion 42 through which the wiring member W passes, or the portion of the wiring member W that extends from the wiring holding component 20, is pulled by heavy machinery or the like.

[0066] As a result, as shown in Figure 6, the protruding portion 24 that houses the wiring member W is pulled away from the door side panel portion 16. Consequently, a force acts on the retaining portion 52 in the direction away from the door side panel portion 16. Since the fastening portions 54A and 54B of the outer part 50 are fastened and fixed to the door side panel portion 16 by screws S, forces acting in different directions act between the retaining portion 52 and the fastening portions 54A and 54B, causing the outer part 50 to break at the easily breakable portion 56.

[0067] As a result, the protruding portion 24 can be disengaged from between the fastening portions 54A and 54B that remain fastened to the door side panel portion 16. This removes the portion of the wiring retaining component 20 other than the fastening portions 54A and 54B from the door side panel portion 16. The wiring member W passing through the cylindrical portion 42 and the protruding portion 24 is removed from the door 10 along with the removed portion of the wiring retaining component 20.

[0068] Furthermore, even if the wiring component W is connected to an electrical component inside the door 10 via a connector, the connector connection can be easily released by pulling the wiring component W forcefully.

[0069] <Effects, etc.> With the wiring retaining component 20 configured as described above, an easily breakable portion 56 is formed in the wiring member retaining portion 22 at a position between the cylindrical portion 42 and the fastening portions 54A and 54B. Therefore, the wiring member retaining portion 22 can be easily separated at the easily breakable portion 56. As a result, the portion of the wiring member retaining portion 22 that holds the wiring member W can be separated from the fastening portions 54A and 54B. As a result, the wiring member W can be easily removed from the door side panel portion 16.

[0070] Furthermore, when the outer part 50, which acts as a fixing part, breaks at the easily breakable part 56, the pressure on the protruding part 24 is released. As a result, the protruding part 24 and the cylindrical part 42 can be easily removed from the door side panel part 16.

[0071] Furthermore, the wiring retaining component 20 includes a first fastening portion 54A and a second fastening portion 54B, with a retaining portion 52 positioned between the first fastening portion 54A and the second fastening portion 54B. As a result, the retaining portion 52 can firmly hold the protruding portion 24, and the protruding portion 24 is firmly fixed to the door side panel portion 16.

[0072] Since an easily breakable portion 56 is formed on the cylindrical portion 42 side of each of the first fastening portion 54A and the second fastening portion 54B, the retaining portion 52 can be easily separated from the door side plate portion 16 while the first fastening portion 54A and the second fastening portion 54B remain on the door side plate portion 16. The protruding portion 24 can also be easily detached from the door side plate portion 16 by passing between the first fastening portion 54A and the second fastening portion 54B.

[0073] Since the easily breakable portion 56 includes a thin-walled portion, the wiring holding component 20 is prone to breaking at the thin-walled easily breakable portion 56.

[0074] [Embodiment 2] The wiring retaining component 120 according to Embodiment 2 will now be described. Figure 7 is an exploded perspective view of the wiring retaining component 120. Figure 8 is a side view of the wiring retaining component 120. In the description of Embodiment 1, the same reference numerals are used for components similar to those described in Embodiment 1, and their descriptions are omitted.

[0075] In this embodiment, the elastic portion 140 corresponding to the elastic component 40 in Embodiment 1 and the outer portion 150 corresponding to the outer component 50 are integrally formed. For example, the elastic portion 140 and the outer portion 150 are integrally formed from an elastic material using a mold.

[0076] To increase the rigidity of the outer portion 150, a metal portion 151 may be placed inside the outer portion 150. For example, a plate-shaped metal portion 151 may be placed inside the outer portion 150 as an insert component.

[0077] The through holes 54h in the fastening portions 54A and 54B of the outer portion 150 should preferably be formed so as to penetrate the metal portion 151. This makes the fastening portions 54A and 54B, into which the screws S are fastened, less likely to be damaged.

[0078] In this embodiment, the protruding exterior portion 46 of the elastic portion 140, the protruding reinforcing portion 34 of the inner component 30, and the outer portion 150 are a wiring member holding portion 122 that keeps the portion of the wiring member W that extends from one end of the cylindrical portion 42 in a state that is aligned with the surface of the door side plate portion 16, and a protruding portion 124 that extends from one end of the cylindrical portion 42 to the outer circumference.

[0079] Furthermore, at least a portion of the protruding portion 124 is the outer portion 150, which is the fixed portion. In addition, the easily breakable portion 156 is formed in the outer portion 150, which is part of the protruding portion 124.

[0080] In the outer portion 150, grooves may not be formed on the outer surface, but grooves 151g may be formed in the metal portion 151 inside the outer portion 150 to form a thin-walled portion 151t, thereby forming an easily breakable portion 156. For example, grooves 151g may be formed between one end of the cylindrical portion 42 and the fastening portion 54A, and between one end of the cylindrical portion 42 and the fastening portion 54B, thereby forming an easily breakable portion 156.

[0081] Even with the wiring retaining component 120 according to Embodiment 2, pulling on the wiring member W causes the outer portion 150 to break at the easily breakable portion 156. That is, the metal portion 151 breaks at the groove 151g, causing the outer portion 150 to break. As a result, the fastening portions 54A and 54B remain fastened and fixed to the door side panel portion 16, while the other protruding portions 124 and the cylindrical portion 42 are removed from the door side panel portion 16 together with the wiring member W.

[0082] Therefore, similar to Embodiment 1, the wiring member W can be easily removed from the door side panel portion 16.

[0083] Furthermore, an outer portion 150, which is a fixing portion, can be provided on the protruding portion 124, reducing the number of parts and making installation to the door 10 easier. In this case, the protruding portion 124 can be divided, and the portion of the wiring holding component 120 that holds the wiring member W and the cylindrical portion 42 can be separated from the fastening portions 54A and 54B, allowing the wiring member W to be easily removed from the door side panel portion 16.

[0084] Furthermore, if the wiring member holding portion 122 includes a metal portion 151, a portion that is easily broken 156 can be easily formed by providing a partially thinned portion 151t in the metal portion 151. A thinned portion may also be formed in the outer portion 150.

[0085] In this example, it is not essential that the outer portion 150 protrudes from the overhang portion 124. For example, the overhang portion 124 may extend out of the recess 17 and onto the surface of the door side panel portion 16, and a fastening portion having a fastening through hole may be formed on the portion that extends onto the surface of the door side panel portion 16.

[0086] [Modifications] The components described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other. For example, the metal part may be embedded in the outer part 150 in Embodiment 1. Also, the metal part may not be placed in the outer part 150 in Embodiment 2. In this case, a groove may be formed on the outer circumferential surface of the outer part to form an easily breakable portion.

[0087] The easily fractured portion does not necessarily have to be formed by a groove. For example, the easily fractured portion may be formed by intermittent holes in the outer portion.
