Description

[Technical Field]

[0001] The present disclosure relates to a grommet and a grommet mounting structure. [Background technology]

[0002] Patent Document 1 discloses a grommet that clamps a wire harness with a clamping body and attaches it to a through-hole in a panel member. This grommet has a hinge part that connects the clamping body and is provided with a hinge cover that protects the hinge part. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-120540 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the grommet disclosed in Patent Document 1, there is a concern that if the hinge cover is damaged, the hinge portion may become exposed. If the hinge portion becomes exposed, there is a risk that flying stones may hit the hinge portion while the vehicle is traveling, causing the hinge portion to be damaged.

[0005] In consideration of the above, an object of the present disclosure is to prevent damage to a hinge portion in a grommet that is attached to a mounting hole in a mounting panel while clamping a wire harness. [Means for solving the problem]

[0006] A grommet of a first aspect of the present disclosure includes a pair of clamping bodies that clamp a wire harness, a hinge portion that connects the pair of clamping bodies so that the pair of clamping bodies can be opened and closed, and an engagement portion that is provided on the pair of clamping bodies and engages with a mounting hole formed in a mounting panel when the wire harness clamped by the pair of clamping bodies and the hinge portion are inserted into the mounting hole.

[0007] The grommet of the first aspect is attached to a mounting panel by engaging the engaging portion with the mounting hole when the wire harness clamped by the pair of clamping bodies and the hinge portion are inserted into the mounting hole. When the grommet is attached to the mounting panel in this manner, the hinge portion is located on the back side of the mounting panel. Therefore, the grommet of the first aspect can prevent damage to the hinge portion due to external force compared to conventional structures in which the hinge portion is located on the front side of the mounting panel.

[0008] A grommet of a second aspect of the present disclosure is a grommet of the first aspect, wherein the hinge portion includes an axis portion provided on one of the clamping bodies and a bearing portion provided on the other clamping body and receiving the axis portion.

[0009] In conventional structures, the hinge portion connecting the pair of clamping bodies is elastically deformed to open and close the pair of clamping bodies, and therefore the hinge portion is made of a resin material that is easily elastically deformed. If the hinge portion is made of such a resin material, there is a risk that the hinge portion will be damaged by repeated opening and closing. In contrast, in the grommet of the second aspect, the hinge portion is composed of a shaft portion of one clamping body and a bearing portion of the other clamping body, and the pair of clamping bodies are connected so as to be able to open and close by having the shaft portion of one clamping body receive the bearing portion of the other clamping body. Therefore, in the grommet, damage to the hinge portion can be suppressed even when the pair of clamping bodies are repeatedly opened and closed, compared to conventional structures.

[0010] A grommet according to a third aspect of the present disclosure is the grommet according to the second aspect, wherein the one clamping body and the shaft portion are integral with each other, and the other clamping body and the bearing portion are integral with each other.

[0011] In the grommet of the third embodiment, one clamping body and the shaft portion are integral, and the other clamping body and the bearing portion are integral, so the number of parts can be reduced compared to, for example, a configuration in which the pair of clamping bodies and the hinge portion are separate.

[0012] A grommet of a fourth aspect of the present disclosure is a grommet of the second or third aspect, wherein one of the clamping bodies comprises a plate portion and a pair of shaft portions protruding in the thickness direction from both plate surfaces of the plate portion, and the other clamping body is arranged on both sides of the plate portion in the thickness direction and comprises a pair of bearing portions that receive the pair of shaft portions, and at the ends of the pair of clamping bodies in the insertion direction into the mounting hole, at least a portion of the outer surface of the plate portions is in the same position as or protruding from the outer surface of the bearing portions.

[0013] In the grommet of the fourth aspect, at least a portion of the outer circumferential surface of the plate portion of the hinge portion is located at the same position as or protrudes from the outer circumferential surface of the bearing portion, which prevents the inner surface of the bearing portion from hitting the edge of the mounting hole when inserting the hinge portion into the mounting hole, compared to a configuration in which the outer circumferential surface of the plate portion of the hinge portion is located more inward than the outer circumferential surface of the bearing portion, thereby preventing damage to the hinge portion when attaching the grommet to the mounting panel.

[0014] A grommet of a fifth aspect of the present disclosure is a grommet of the second or third aspect, wherein one of the clamping bodies comprises a plate portion and a pair of shaft portions protruding in the thickness direction from both plate surfaces of the plate portion, and the other clamping body is arranged on both sides of the plate portion in the thickness direction and comprises a pair of bearing portions that receive the pair of shaft portions, and at the ends of the pair of clamping bodies in the insertion direction into the mounting hole, the edges of the pair of bearing portions are connected to each other by a connecting portion.

[0015] In the grommet of the fifth aspect, the edges of the pair of bearings are connected to each other by a connecting portion at the hinge portion, which prevents the inside of the bearings from hitting the edge of the mounting hole when inserting the hinge portion into the mounting hole in the mounting panel, compared to a configuration in which the edges of the pair of bearings are not connected to each other by a connecting portion, thereby preventing damage to the hinge portion when attaching the grommet to the mounting panel.

[0016] A grommet of a sixth aspect of the present disclosure is a grommet of any one of the first to fifth aspects, in which the clamping body and the engaging portion are integral, and the engaging portion elastically engages with the edge of the mounting hole.

[0017] In the grommet of the sixth aspect, the clamping body and the engaging portion are integrated, which allows for a reduction in the number of parts compared to, for example, a configuration in which the clamping body and the engaging portion are separate. Furthermore, in the grommet, the engaging portion elastically engages with the edge of the mounting hole, providing a sense of click when inserting the pair of clamping bodies into the mounting hole. In other words, the elastic force (repulsive force) generated when the engaging portion engages with the edge of the mounting hole allows the user to recognize that the engaging portion has engaged with the edge of the mounting hole.

[0018] A grommet of a seventh aspect of the present disclosure is a grommet of any one of the first to sixth aspects, wherein the pair of clamping bodies are provided with insertion stop portions that abut against the edge of the mounting hole on the opposite side from the engagement portion, sandwiching the edge of the mounting hole when the pair of clamping bodies are inserted into the mounting hole.

[0019] In the grommet of the seventh aspect, the pair of clamping bodies are provided with insertion stoppers, which abut against the edge of the mounting hole in the mounting panel, preventing the pair of clamping bodies from being inserted too far into the mounting hole. Furthermore, when the pair of clamping bodies are inserted into the mounting hole, the edge of the mounting hole is clamped between the engagement portion and the insertion stoppers, preventing the pair of clamping bodies from rattling.

[0020] A grommet according to an eighth aspect of the present disclosure is the grommet according to any one of the first to seventh aspects, wherein the pair of clamping bodies include holding portions that house and hold the wire harness in a closed state.

[0021] In the grommet of the eighth aspect, when the pair of clamping bodies are closed, the wire harness is housed and held in the holding portion, thereby making it possible to prevent damage to the wire harness by the holding portion in the grommet.

[0022] A grommet according to a ninth aspect of the present disclosure is the grommet according to the eighth aspect, wherein the holding portion is inserted through the mounting hole with the pair of clamping bodies inserted into the mounting hole.

[0023] In the grommet of the ninth aspect, the holding portion is inserted through the mounting hole with the pair of clamping bodies inserted into the mounting hole, so that the wire harness can be prevented from coming into contact with the edge portion of the mounting hole.

[0024] A tenth aspect of the grommet of the present disclosure is the grommet of the ninth aspect, wherein the longitudinal direction of the holding portion is inclined with respect to the hole axis direction of the mounting hole when the pair of clamping bodies are inserted into the mounting hole.

[0025] In the grommet of the tenth aspect, the longitudinal direction of the holding portion is inclined with respect to the axial direction of the mounting hole, so that, compared to a configuration in which the longitudinal direction of the holding portion and the axial direction of the mounting hole are aligned, the amount by which the wire harness protrudes from the mounting panel (protrusion height) is reduced, making it possible to suppress damage to the wire harness due to external forces and improving the handling of the wire harness.

[0026] An eleventh aspect of the grommet of the present disclosure is a grommet of any one of the first to tenth aspects, comprising a first locking portion provided on one of the clamping bodies and a second locking portion provided on the other of the clamping bodies and with which the first locking portion is locked, and the first locking portion and the second locking portion are locked together when the pair of clamping bodies are open.

[0027] In the grommet of the eleventh aspect, the first and second locking portions are locked together when the pair of clamping bodies is in the open state, i.e., the pair of clamping bodies is maintained in the open state by the locking of the first and second locking portions. In this way, the grommet can be transported with the pair of clamping bodies in the open state.

[0028] A grommet according to a twelfth aspect of the present disclosure is the grommet according to any one of the first to eleventh aspects, wherein the mounting panel is a vehicle body panel.

[0029] The grommet of the twelfth embodiment is attached to the mounting panel, which is a vehicle body panel. When the grommet is attached to the vehicle body panel, the hinge portion is located on the rear side of the vehicle body panel. Therefore, compared to conventional structures in which the hinge portion is located on the front side of the mounting panel, the grommet can prevent flying stones from hitting the hinge portion while the vehicle is moving. In other words, damage to the hinge portion due to external forces can be prevented.

[0030] The grommet mounting structure of the thirteenth aspect comprises a mounting panel having a mounting hole formed therein, a pair of clamping bodies that clamp a wire harness, a grommet having a hinge portion that connects the pair of clamping bodies so that the pair of clamping bodies can be opened and closed, and an engaging portion that is provided on the pair of clamping bodies and engages with the mounting hole when the wire harness clamped by the pair of clamping bodies and the hinge portion are inserted into a mounting hole formed in the mounting panel.

[0031] In the grommet mounting structure of the thirteenth aspect, the wire harness clamped by the pair of clamping bodies and the hinge portion are inserted into the mounting hole, and the engaging portion engages with the mounting hole, thereby mounting the grommet to the mounting panel. When the grommet is mounted to the mounting panel in this manner, the hinge portion is located on the back side of the mounting panel. Therefore, the grommet mounting structure of the thirteenth aspect can suppress damage to the hinge portion due to external force compared to conventional structures in which the hinge portion of the grommet is located on the front side of the mounting panel. [Effects of the Invention]

[0032] According to the present disclosure, in a grommet that is attached to a mounting hole in a mounting panel while clamping a wire harness, damage to a hinge portion can be suppressed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0034] Next, a grommet and a grommet mounting structure according to an embodiment of the present disclosure will be described with reference to the drawings.

[0035] <Grommet 30> As shown in Figures 1 to 14, the grommet 30 of this embodiment is a component that is attached to a mounting hole 102 formed in a mounting panel 100 while holding a wire harness 90. An example of the mounting panel 100 of this embodiment is a vehicle body panel (i.e., a panel member used in a vehicle body). However, the present disclosure is not limited to this configuration. The mounting panel 100 may also be a panel member other than a vehicle body panel.

[0036] As shown in FIGS. 1 to 3, the grommet 30 includes a pair of clamping bodies 32, 42, a hinge portion 50, and engaging portions 34, 44.

[0037] (Pair of clamping bodies 32, 42) 1 and 2, the pair of clamping bodies 32, 42 are members capable of clamping the wire harness 90. Specifically, the pair of clamping bodies 32, 42 are connected by a hinge portion 50 so as to be able to open and close, and in a closed state, can clamp the wire harness 90 from both sides.

[0038] 1 and 2, the pair of clamping bodies 32, 42 of this embodiment are connected at one end in the longitudinal direction by a hinge portion 50. Meanwhile, the pair of clamping bodies 32, 42 are locked at the other end in the longitudinal direction by a locking portion 60. Specifically, the pair of clamping bodies 32, 42 are maintained in a closed state by engagement (lock) between a locking claw 62 and a hooking portion 64 provided at the other end in the longitudinal direction of the pair of clamping bodies 32, 42. More specifically, the hooking portion 64 is formed at the other end in the longitudinal direction of one clamping body 32, and the locking claw 62 that is elastically engaged with (resilient hooked on) the hooking portion 64 is formed at the other end in the longitudinal direction of the other clamping body 42. In the following, when the pair of clamping bodies 32, 42 is referred to as being in a closed state, it refers to a state in which the pair of clamping bodies 32, 42 are maintained in a closed state, i.e., a state in which the pair of clamping bodies 32, 42 are locked by the locking section 60.

[0039] As shown in FIGS. 7 and 8 , the pair of clamping bodies 32, 42 includes holding portions 36, 46 that accommodate and hold the wire harness 90 in a closed state. Specifically, the holding portion 36 is formed on the clamping surface side of the clamping body 32. The holding portion 36 is a groove-shaped portion sized to accommodate the wire harness 90. The bottom surface of the holding portion 36 is a curved surface that curves in an arc. On the other hand, the holding portion 46 is formed on the clamping surface side of the clamping body 42. The holding portion 46 is a portion that closes the opening of the holding portion 36 (the opening of the groove). When the pair of clamping bodies 32, 42 are closed, the holding portion 46 closes the opening of the holding portion 36 in which the wire harness 90 is accommodated, and the wire harness 90 is held by the holding portions 36, 46. Furthermore, since the bottom surface of the holding portion 36 is a curved surface, damage to the wire harness 90 can be suppressed.

[0040] 1 and 5, the retaining portions 36, 46 are inserted through the mounting hole 102 when the pair of clamping bodies 32, 42 are inserted into the mounting hole 102. That is, the groove-shaped retaining portion 36 is inserted through the mounting hole 102. In other words, one longitudinal end of the retaining portion 36 (i.e., one longitudinal end of the groove) is located outside the opening on one side of the mounting hole 102, and the other longitudinal end (i.e., the other longitudinal end of the groove) is located outside the opening on the other side of the mounting hole 102. In the following description, when the pair of clamping bodies 32, 42 is referred to as being inserted into the mounting hole 102, it refers to a state in which the pair of clamping bodies 32, 42 are inserted into the mounting hole 102 and the engaging portions 34, 44 are engaged with the mounting hole 102. Also, the symbol ID in the drawings indicates the insertion direction of the grommet 30.

[0041] 1, the longitudinal direction LD of the holding portion 36 is inclined with respect to the hole axis direction HAD of the mounting hole 102 in a state in which the pair of clamping bodies 32, 42 are inserted into the mounting hole 102.

[0042] (hinge part 50) As shown in FIGS. 1 to 3, the hinge portion 50 is a portion that connects the pair of clamping bodies 32, 42 so that they can be opened and closed.

[0043] 6, 8, and 9, the hinge portion 50 is configured to include a shaft portion 52 included in the clamping body 32, and a bearing portion 54 included in the clamping body 42 that receives the shaft portion 52. Specifically, the clamping body 32 includes a plate portion 38 and a pair of shaft portions 52 that protrude in the plate thickness direction from both plate surfaces of the plate portion 38. More specifically, the plate portion 38 that forms one end portion of the clamping body 32 in the longitudinal direction is provided with a pair of cylindrical shaft portions 52 that protrude in the plate thickness direction.

[0044] Furthermore, the holding body 32 and the pair of shaft portions 52 are integral with each other. Specifically, the holding body 32 and the pair of shaft portions 52 are integrally formed.

[0045] The clamping body 42 is provided with a pair of bearing portions 54 that are arranged on both sides of the plate portion 38 in the plate thickness direction and that receive the pair of shaft portions 52. More specifically, the pair of bearing portions 54 are annular portions that are respectively provided at one end of the clamping body 42 in the longitudinal direction, and the shaft portions 52 are inserted into the inner hollow portions to support the shaft portions 52 rotatably.

[0046] Furthermore, the holding body 42 and the pair of bearing portions 54 are integrally formed. Specifically, the holding body 42 and the pair of bearing portions 54 are integrally formed.

[0047] 4 and 6, in the hinge portion 50, at least a portion of the outer peripheral surface 38A of the plate portion 38 is flush with or protrudes from the outer peripheral surface 54A of the bearing portion 54. In this embodiment, when viewed in the rotation axis direction of the hinge portion 50, i.e., the axial direction of the shaft portion 52, a portion of the outer peripheral surface 38A (the end portion on the insertion direction side of the grommet 30) is flush with the outer peripheral surface 54A of the bearing portion 54.

[0048] (Engagement portions 34, 44) As shown in FIGS. 2 and 4, the engaging portions 34, 44 are portions that engage with the mounting holes 102 to mount the pair of clamping bodies 32, 34 to the mounting holes 102.

[0049] The engaging portions 34, 44 are provided on the pair of clamping bodies 32, 34. The engaging portions 34, 44 are engaged with the mounting holes 102 formed in the mounting panel 100 when the wire harness 90 and the hinge portion 50 clamped between the pair of clamping bodies 32, 34 are inserted into the mounting holes 102. Specifically, the engaging portions 34 are provided in the longitudinal middle of the clamping body 32. The engaging portions 34 are elastically engaged with the edges of the mounting holes 102. The engaging portions 34 are integral with the clamping body 32. Specifically, the engaging portions 34 and the clamping body 32 are integrally molded. The engaging portions 34 include an elastic plate portion 34A and a claw portion 34B. The end of the elastic plate portion 34A on the shaft portion 52 side of the clamping body 32 is supported by the clamping body 32, and the end of the elastic plate portion 34A opposite the shaft portion 52 of the clamping body 32 is a free end. The claw portion 34B is provided on the free end side of the elastic plate portion 34A. The claw portion 34B is also provided on the outer surface side of the elastic plate portion 34A, i.e., on the side opposite the clamping surface (holding portion 36) of the clamping body 32. The claw portion 34B catches on the edge of the mounting hole 102, thereby engaging the engaging portion 34 with the mounting hole 102.

[0050] The engaging portion 44 is provided in the longitudinal middle of the clamping body 42. Specifically, when the pair of clamping bodies 32, 34 are closed, the engaging portion 44 is positioned opposite the engaging portion 34. The engaging portion 44 elastically engages with the edge of the mounting hole 102. The engaging portion 44 is integral with the clamping body 42. Specifically, the engaging portion 44 and the clamping body 42 are integrally molded. The engaging portion 44 has an elastic plate portion 44A and a claw portion 44B. The end of the elastic plate portion 44A facing the bearing portion 54 of the clamping body 42 is supported by the clamping body 42, and the end of the clamping body 42 opposite the bearing portion 54 is a free end. The claw portion 44B is provided on the free end side of the elastic plate portion 44A. The claw portion 44B is provided on the outer surface side of the elastic plate portion 44A, i.e., on the side opposite to the clamping surface (holding portion 46) of the clamping body 42. The claw portion 44B catches on the edge of the mounting hole 102, thereby causing the engaging portion 44 to engage with the mounting hole 102.

[0051] Moreover, the grommet 30 of this embodiment further includes insertion stop portions 70 and 72, a first locking portion 80, and a second locking portion .

[0052] (insertion stoppers 70, 72) As shown in FIGS. 1, 8 and 12, the insertion stoppers 70 and 72 are portions that act as insertion stoppers when the pair of clamping bodies 32 and 34 are inserted into the mounting hole 102.

[0053] The insertion stoppers 70, 72 are provided on the pair of clamping bodies 32, 34. Specifically, the insertion stoppers 70, 72 are provided so as to abut the edge of the mounting hole 102 on the side opposite the engaging portions 34, 44, sandwiching the edge of the mounting hole 102 when the pair of clamping bodies 32, 34 are inserted into the mounting hole 102. More specifically, the insertion stopper 70 is provided on the clamping body 32. The insertion stopper 70 is a protruding portion that protrudes in the same direction as the claw portion 34B. The clamping body 32 and the insertion stopper 70 are integral with each other. That is, the clamping body 32 and the insertion stopper 70 are molded as a single unit. The insertion stopper 70 is located on the side opposite the engaging portion 34, sandwiching the edge of the mounting hole 102, when the pair of clamping bodies 32, 34 are inserted into the mounting hole 102.

[0054] Furthermore, the insertion stop portion 72 is provided on the clamping body 42. This insertion stop portion 72 is a protruding portion that protrudes in the same direction as the claw portion 44B. When the pair of clamping bodies 32, 34 is closed, the insertion stop portion 72 is located on the opposite side of the insertion stop portion 70. Furthermore, the clamping body 42 and the insertion stop portion 72 are integral with each other. That is, the clamping body 42 and the insertion stop portion 72 are integrally molded. When the pair of clamping bodies 32, 34 are inserted into the mounting hole 102, the insertion stop portion 72 is located on the opposite side of the engaging portion 44, sandwiching the edge of the mounting hole 102 between them.

[0055] 7 and 8, in this embodiment, the range from the tip of grommet 30 in the insertion direction into mounting hole 102 to insertion stoppers 70 and 72 is the portion that is inserted into mounting hole 102 of grommet 30. Hereinafter, the portion that is inserted into mounting hole 102 of grommet 30 will be referred to as insertion portion 31.

[0056] (First locking portion 80 and second locking portion 82) As shown in FIG. 6, the first locking portion 80 and the second locking portion 82 are portions for maintaining the pair of clamping bodies 32, 34 in an open state.

[0057] The first locking portions 80 are provided on the clamping body 32. Specifically, the first locking portions 80 are provided on the outer peripheral surfaces of the pair of shaft portions 52, respectively. More specifically, the first locking portions 80 are protrusions that protrude radially outward from the outer peripheral surfaces of the shaft portions 52, and are locked to the second locking portions 82 when the pair of clamping bodies 32, 34 are in an open state.

[0058] The second locking portions 82 are provided on the clamping body 42. Specifically, the second locking portions 82 are provided on the outer peripheral surfaces of the pair of bearing portions 54, respectively. More specifically, the second locking portions 82 are protrusions that protrude from the inner surfaces of the bearing portions 54 (the surfaces on the opposing sides of the pair of bearing portions 54) toward the opposing bearing portion 54, and are locked to the first locking portions 80 when the pair of clamping bodies 32, 34 are in an open state.

[0059] As described above, the first locking portion 80 and the second locking portion 82 are locked to each other when the pair of clamping bodies 32, 34 is in an open state. That is, the first locking portion 80 and the second locking portion 82 maintain the pair of clamping bodies 32, 34 in an open state.

[0060] In this embodiment, the clamping body 32 and the clamping body 42 are each an integrally molded resin product.

[0061] <Grommet mounting structure S> 12, the grommet mounting structure S of this embodiment is a structure in which a grommet 30 is mounted to a mounting panel 100. Specifically, the grommet mounting structure S is a structure in which the grommet 30, which holds a wire harness 90, is mounted in a mounting hole 102 of the mounting panel 100. This grommet mounting structure S includes the above-mentioned mounting panel 100 and the grommet 30 mounted to the mounting panel 100.

[0062] Next, the effects of this embodiment will be described.

[0063] The grommet 30 of this embodiment is attached to the mounting panel 100 by inserting the wire harness 90 and hinge portion 50, which are held between the pair of clamping bodies 32, 42, into the mounting hole 102, and then engaging the engaging portions 34, 44 with the mounting hole 102 (see FIGS. 10 to 12). With the grommet 30 attached to the mounting panel 100 in this manner, the hinge portion 50 is located on the back side of the mounting panel 100. Therefore, the grommet 30 of this embodiment can prevent damage to the hinge portion 50 due to external forces, compared to conventional structures in which the hinge portion 50 is located on the front side of the mounting panel 100.

[0064] In conventional structures, the hinge portion connecting the pair of clamping bodies is elastically deformed to open and close the pair of clamping bodies, and therefore the hinge portion is made of a resin material that is easily elastically deformed. If the hinge portion is made of such a resin material, there is a risk that the hinge portion will be damaged by repeated opening and closing. In contrast, in the grommet 30 of this embodiment, the hinge portion 50 is formed by the shaft portion 52 of the clamping body 32 and the bearing portion 54 of the clamping body 42, and the pair of clamping bodies 32, 42 are connected so as to be able to open and close by having the shaft portion 52 of the clamping body 32 receive the bearing portion 54 of the clamping body 42. Therefore, compared to conventional structures, the grommet 30 can suppress damage to the hinge portion 50 even when the pair of clamping bodies 32, 472 are repeatedly opened and closed.

[0065] In the grommet 30 of this embodiment, the clamping body 32 and the shaft portion 52 are integral, and the clamping body 42 and the bearing portion 54 are integral, so the number of parts can be reduced compared to, for example, a configuration in which the pair of clamping bodies and the hinge portion are separate.

[0066] In the grommet 30 of this embodiment, at least a portion of the outer peripheral surface of the plate portion 38 of the hinge portion 50 is located at the same position as or protruding from the outer peripheral surface of the bearing portion 54. Therefore, compared to a configuration in which the outer peripheral surface of the plate portion 38 of the hinge portion 50 is located more inward than the outer peripheral surface of the bearing portion 54, when the hinge portion 50 is inserted into the mounting hole 102 of the mounting panel 100, it is possible to prevent the inside of the bearing portion 54 from hitting the edge of the mounting hole 102. This makes it possible to prevent damage to the hinge portion 50 when the grommet 30 is attached to the mounting panel 100.

[0067] In the grommet 30 of this embodiment, the clamping body 32 and the engaging portion 34 are integrated, and the clamping body 42 and the engaging portion 44 are integrated, so that the number of parts can be reduced compared to, for example, a configuration in which the clamping body and the engaging portion are separate. Furthermore, in the grommet 30, the engaging portions 34, 44 elastically engage with the edge of the mounting hole 102, so that a sense of click is provided when inserting the pair of clamping bodies 32, 42 into the mounting hole 102. In other words, the elastic force (repulsion force) generated when the engaging portions 34, 44 engage with the edge of the mounting hole 102 allows the user to recognize that the engaging portions 34, 44 have engaged with the edge of the mounting hole 102.

[0068] In the grommet 30 of this embodiment, the pair of clamping bodies 32, 42 are provided with insertion stoppers 70, 72, which abut against the edge of the mounting hole 102 in the mounting panel 100, thereby preventing the pair of clamping bodies 32, 42 from being inserted too far into the mounting hole 102. Furthermore, when the pair of clamping bodies 32, 42 are inserted into the mounting hole 102, the edge of the mounting hole 102 is clamped between the engaging portion 34 and the insertion stopper 70, and between the engaging portion 44 and the insertion stopper 72, preventing the pair of clamping bodies 32, 42 from rattling.

[0069] In the grommet 30 of this embodiment, when the pair of clamping bodies 32, 42 are closed, the wire harness 90 is housed and held in the holding portions 36, 46. As a result, in the grommet 30, the holding portions 36, 46 can prevent damage to the wire harness 90.

[0070] In the grommet 30 of this embodiment, the pair of clamping bodies 32, 42 are inserted into the mounting hole 102 and the holding portions 36, 46 are inserted through the mounting hole 102, thereby preventing the wire harness 90 from coming into contact with the edge portion of the mounting hole 102.

[0071] In the grommet 30 of this embodiment, the longitudinal direction of the holding portions 36, 46 is inclined with respect to the axial direction of the mounting hole 102. Therefore, compared to a configuration in which the longitudinal direction of the holding portions 36, 46 and the axial direction of the mounting hole 102 are aligned, the amount by which the wire harness 90 protrudes from the mounting panel 100 (protrusion height) is reduced, making it possible to suppress damage to the wire harness 90 due to external forces. In addition, the wire harness 90 can be handled more easily. Furthermore, since the longitudinal direction of the holding portions 36, 46 is inclined with respect to the hole axis direction of the mounting hole 102, the length of the holding portions 36, 46 that hold the wire harness 90 is increased by the amount of inclination, and the adjustment range of the holding strength that holds the wire harness 90 can be increased.

[0072] In grommet 30 of this embodiment, first locking portion 80 and second locking portion 82 are locked with pair of clamping bodies 32, 42 in an open state, i.e., the pair of clamping bodies 32, 42 are maintained in an open state by locking first locking portion 80 and second locking portion 82. In this way, grommet 30 allows the pair of clamping bodies 32, 42 to be transported in an open state.

[0073] The grommet 30 of this embodiment is attached to the vehicle body panel because the mounting panel 100 is a vehicle body panel. When the grommet 30 is attached to the vehicle body panel in this manner, the hinge portion 50 is located on the back side of the vehicle body panel. Therefore, compared to conventional structures in which the hinge portion 50 is located on the front side of the mounting panel 100, the grommet 30 can prevent flying stones from hitting the hinge portion 50 while the vehicle is traveling. In other words, damage to the hinge portion 50 due to external forces can be prevented.

[0074] (Other embodiments) In the grommet 30 of the embodiment described above, as shown in Fig. 9, at least a portion of the outer peripheral surface 38A of the plate portion 38 is flush with or protrudes from the outer peripheral surface 54A of the bearing portion 54 in the hinge portion 50, but the present disclosure is not limited to this configuration. For example, as in a grommet 110 shown in Figs. 13 and 14, at the hinge portion 50, the outer peripheral surface 54A of the bearing portion 54 may be in a position that protrudes more than the outer peripheral surface 38A of the plate portion 38, and the edges of the pair of bearing portions 54 may be connected to each other by a connecting portion 112. In grommet 110 configured as described above, the edges of the pair of bearing portions 54 in hinge portion 50 are connected by connecting portion 112, and therefore, compared to a configuration in which, for example, outer peripheral surface 54A of bearing portion 54 is positioned to protrude more than outer peripheral surface 38A of plate portion 38 and the edges of the pair of bearing portions 54 are not connected by connecting portion 112, it is possible to prevent the inside of bearing portion 54 from hitting the edge of mounting hole 102 when inserting hinge portion 50 into mounting hole 102 of mounting panel 100. This makes it possible to prevent damage to hinge portion 50 when mounting grommet 110 to mounting panel 100.

[0075] In the above-described embodiment, the other longitudinal ends of the pair of clamping bodies 32, 42 are locked together by a locking section 60 including a locking claw 62 and a hooking section 64, but the configuration is not limited to using the locking claw 62 and the hooking section 64 as long as the other longitudinal ends of the pair of clamping bodies 32, 42 can be locked together.

[0076] The above describes one embodiment of the present disclosure, but the present disclosure is not limited to the above, and it goes without saying that it can be implemented in various other modified forms within the scope that does not deviate from the gist of the present disclosure.
