Abstract
Description
Technical Field
[0001] The present invention relates to, for example, a grommet, a grommet inner, and a harness with a grommet for protecting a wire harness inserted therein.
Background Art
[0002] A wire harness inserted through an insertion hole provided in a panel is inserted into a cylindrical grommet attached to the insertion hole in order to prevent interference and damage with the insertion hole. For example, Patent Document 1 discloses a grommet in which a grommet inner provided with a split body that can be split into two is attached to a mounting portion provided at an end of a grommet body through which a wire harness is inserted.
[0003] In the grommet disclosed in Patent Document 1, by locking and fixing the split bodies sandwiching a desired position in the wire harness, the grommet inner can be easily assembled at the desired position of the wire harness, and the grommet inner can be attached to the attachment portion. The grommet inner thus attached to the attachment portion can hold the grommet on the panel in a state where a part thereof is inserted through an insertion hole provided in the panel. Thereby, it is possible to prevent the wire harness inserted through the grommet from interfering with the peripheral edge portion of the insertion hole.
[0004] However, when an unintended external force acts on one of the split bodies, there is a risk that the split bodies rotate relative to each other with the locking portion as a fulcrum so that the split bodies move apart from each other. In this case, a gap may occur between the split bodies, and there is a risk that the wire harness may be sandwiched between the split bodies. Further, since the grommet inner expands in the separating direction as the split bodies separate, the diameter of the portion of the grommet inner that should pass through the insertion hole becomes larger than the inner diameter of the insertion hole, and there is a risk that the grommet cannot be fixed to the vehicle body panel.

[0005] [Patent Document 1] Japanese Patent Publication No. 2003-180019 [Overview of the project] [Problems that the invention aims to solve]
[0006] The purpose of this invention is to provide a grommet, a grommet inner, and a harness with a grommet that can restrict relative rotation with the locking portion between the divided parts as a pivot point. [Means for solving the problem]
[0007] This invention comprises a cylindrical grommet body through which a wire harness is routed, and a grommet inner attached to one end of the grommet body to hold the grommet body to a panel. The grommet body is provided with a mounting portion for attaching the grommet inner and for attaching to the panel. The grommet inner is provided with a divided body that can be divided into two in an intersecting direction that intersects the mounting direction for attaching the mounting portion to the panel, and a locking portion for locking and fixing the divided body together. The locking portion is located on one side of the divided body in the intersecting direction. One of the divided bodies is designated as the first divided body, and the other divided body located on the other side in the intersecting direction is designated as the second divided body. The first divided body has a pressed portion that is pressed in a direction away from the second divided body by the wire harness through which it is inserted. At least one of the first divided body and the second divided body is provided with a restricting portion that restricts relative rotation of the divided bodies with the locking portion as a fulcrum, such that the pressed portion is pressed, causing them to move apart from each other. The restricting portion and the locking portion are grommets provided at a predetermined distance apart. Furthermore, this invention is characterized by being a grommet-equipped harness comprising the grommet described above and a wire harness routed inside the grommet.
[0008] Furthermore, this invention relates to a grommet inner that is provided on a cylindrical grommet body through which a wire harness is routed, and which is attached to a mounting portion that is attached to a panel, and is provided with a divided body that can be divided into two in an intersecting direction that intersects with the mounting direction for attaching the mounting portion to the panel, and a locking portion that locks and fixes the divided bodies together, wherein one of the divided bodies located on one side of the intersecting direction is called the first divided body, and the other divided body located on the other side of the intersecting direction is called the second divided body, the first divided body has a pressed portion that is pressed in a direction away from the second divided body by the wire harness through which it is inserted, and at least one of the first divided body and the second divided body is provided with a restricting portion that restricts relative rotation of the divided bodies with the locking portion as a fulcrum so that they move apart from each other when the pressed portion is pressed, and the restricting portion and the locking portion are provided at a predetermined distance apart.
[0009] The restricting portion is separate from the locking portion and is provided at a predetermined distance from the locking portion. The restricting portion also includes a structure that restricts rotation with the locking portion as a fulcrum by having the pressed portion and a part of the first divided body other than the pressed portion come into contact with a part of the second divided body.
[0010] This invention makes it possible to restrict relative rotation between divided parts using the locking portion as a pivot point. More specifically, because the wire harness has a certain rigidity, when the wire harness inserted through the grommet is routed toward the first divided body, the wire harness may press against a pressure-receiving portion provided on the first divided body. When the wire harness presses against the pressure-receiving portion, an external force acts on the first divided body that causes the first divided body and the second divided body to rotate relative to each other with the locking portion as a pivot point, so that they move apart from each other. However, a restricting portion provided at a predetermined distance from the locking portion can restrict the relative rotation between the first divided body and the second divided body with the locking portion as a pivot point. Therefore, separation between the first divided body and the second divided body can be suppressed.
[0011] Furthermore, since the restricting portion is provided at a predetermined distance from the locking portion, the distance between the locking portion, which acts as the pivot point for relative rotation, and the restricting portion can be ensured. Therefore, the restricting portion can restrict the relative rotation between the first and second divided body so that the rotation angle of the first divided body with the locking portion as the pivot point relative to the second divided body is sufficiently small. Thus, separation between the divided body parts can be reliably suppressed, and gaps between the divided body parts can be reliably suppressed. Furthermore, the segmented body may be configured to be further segmentable in areas not pressed by the wire harness. In other words, the grommet inner may be divided into two or more sections.
[0012] In an embodiment of this invention, the restricting portion may consist of a protruding piece projecting from at least one side of the first divided body and the second divided body toward the other side, and a contact restricting portion provided on the other side that, by rotation with the locking portion which separates the divided bodies as a fulcrum, contacts and restricts at least the end face of the protruding piece along the intersecting direction.
[0013] The protruding piece and the contact restricting portion include cases where the end face of the protruding piece along the intersecting direction and the contact restricting portion are in contact when the first divided body and the second divided body are locked and fixed together, and cases where the end face of the protruding piece along the intersecting direction and the contact restricting portion are in contact when the first divided body and the second divided body rotate relative to each other.
[0014] This invention allows for the restriction of relative rotation between the first and second parts with a simple structure in which a protruding piece projecting from at least one side of the first and second parts toward the other side abuts against a contact restricting portion provided on the other side of the first and second parts.
[0015] In another embodiment of this invention, the protruding piece may be provided on the first divided body, and the contact restricting portion may be provided on the second divided body. This invention allows for the restriction of relative rotation between the first and second divided parts with respect to the locking portion, which acts as a pivot point, by a protruding piece provided on the first divided part having a pressed portion that is pressed against by the wire harness, and a contact restricting portion provided on the second divided part that is not pressed against by the wire harness.
[0016] In another aspect of this invention, the pressed portion may be provided so that, when attached to the panel, the side of the first divided body opposite to the panel spans a direction perpendicular to the mounting direction and the intersecting direction, and the protruding pieces may protrude in pairs from both ends of the pressed portion in the direction perpendicular to the panel.
[0017] This invention allows the relative rotation of the first divided body caused by the wire harness pressing against the pressed portion to be restricted by a pair of protruding pieces and contact restricting parts that come into contact with the protruding pieces. Therefore, the relative rotation of the first divided body and the second divided body with the locking portion as the pivot point can be restricted stably and reliably.
[0018] Furthermore, the protruding pieces extend from both ends of the pressed portion in a direction perpendicular to the routing path of the wire harness that passes through the central portion. Therefore, it is possible to maintain the distance between the wire harness that passes through the central portion and the pressed portion, and to suppress the wire harness from pressing against the pressed portion. Consequently, relative rotation with the locking portion between the first and second divided parts as the fulcrum can be suppressed.
[0019] In another aspect of this invention, the protruding piece may be configured as a plate-like shape along the mounting direction. This invention improves the strength of the protruding piece, thereby more reliably restricting relative rotation with the locking portion between the first and second parts as a fulcrum. As a result, a grommet inner can be formed in which the first and second parts are locked together in the desired state, and the grommet inner can be properly fixed to the mounting portion.
[0020] In addition, when a protruding piece formed in a plate shape is provided on the pressed portion, the strength of the pressed portion can also be improved. Therefore, it is possible to suppress damage to the pressed portion due to the pressing by the wire harness.
[0021] As an aspect of the present invention, the locking portion is provided on the second divided body and includes a locking piece that extends toward the first divided body, and a locking frame that is provided on the first divided body and into which the locking piece is inserted and locked. The protruding piece may be arranged on the side opposite to the panel side of the locking piece in the locked state between the first divided body and the second divided body.
[0022] According to the present invention, the distance from the position where the locking piece and the locking frame are locked to the contact portion between the protruding piece and the contact restricting portion can be set long. Therefore, even with a relative rotation of a minute rotation angle of the first divided body with the locking portion as a fulcrum, the protruding piece and the contact restricting portion can be brought into contact with each other, and the relative rotation with the locking portion between the first divided body and the second divided body as a fulcrum can be regulated more accurately. Therefore, it is possible to more reliably suppress the separation between the divided bodies, and more reliably suppress the generation of a gap between the divided bodies.
[0023] As an aspect of the present invention, the pressed portion is formed in a plate shape that straddles the side opposite to the panel of the first divided body in the state of being attached to the panel in a direction orthogonal to the attachment direction and the crossing direction. The restricting portion protrudes from the second divided body toward the first divided body, and may be constituted by a protruding contact portion that contacts at least the end face on the side opposite to the panel side of the pressed portion by rotation with the locking portion between the divided bodies as a fulcrum such that the divided bodies are separated from each other.
[0024] According to the present invention, the relative rotation with the locking portion between the divided bodies as a fulcrum can be regulated. Specifically, the protruding contact portion protrudes from the second divided body toward the first divided body and is provided at a predetermined interval from the locking portion. Therefore, as the first divided body rotates relative to the locking portion as a fulcrum, the protruding contact portion can be brought into contact with the end face on the side opposite to the panel side of the pressed portion provided on the first divided body. Accordingly, the relative rotation about the locking portion between the first divided body and the second divided body can be restricted.
[0025] Also, as an aspect of the present invention, a connector fixing portion for fixing a connector provided on one end side of the wire harness may be provided on the second divided body. According to the present invention, since the wire harness inserted through the grommet body can be fixed, for example, during transportation, the unintended movement of the wire harness can be restricted. Accordingly, it is possible to suppress the wire harness from pressing the pressed portion.
Effect of the Invention
[0026] According to the present invention, it is possible to provide a grommet, a grommet inner, and a harness with a grommet that can restrict relative rotation about the locking portion between the divided bodies.

[0033] Figures 9 and 10 show cross-sectional views corresponding to the cross-section viewed via arrow AA in Figure 4(b). In Figure 9, the grommet body 30 is shown with a dotted line to clearly indicate the routing direction of the harness 10 through which the inner 40 is inserted, with the inner 40 attached to the vehicle body mounting portion 32. Also, in Figures 9 and 10, for convenience, the harness 10 is shown with a dashed line to clarify the configuration of the inner 40, and is illustrated as if the harness 10 is transparent.
[0034] Here, in Figure 3, the vertical direction is defined as the height direction H, and the direction perpendicular to the height direction H and in which the first divided body 50 and the second divided body 60 are attached and detached is defined as the first direction L. The direction perpendicular to both the first direction L and the height direction H is defined as the second direction W. In Figure 3, along the first direction L, the right side is defined as the front side LA, and the left side as the rear side LB; along the height direction H, the downward side is defined as the downward side HD, and the upward side as the upward side HU; along the second direction W, the left side is defined as the left side WL, and along the second direction W, the right side is defined as the right side WR. The above directions correspond to the directions in Figures 4 to 10.
[0035] As shown in Figure 1, the grommet-equipped harness 1 consists of a harness 10 and a resin grommet 20 through which the harness 10 is inserted. The harness 10 is a so-called wire harness, and as shown in Figure 2(a), it consists of a long harness body 11 and a connector 12 attached to one end of the harness body 11.
[0036] The harness body 11 is constructed by bundling together multiple insulated wires, each in which a conductor is surrounded by an insulating coating. Therefore, the harness body 11 has a predetermined rigidity. As shown in Figure 2(a), connector 12 is a roughly rectangular parallelepiped female connector electrically connected to the harness body 11, and has an opening (not shown) at one end for inserting the mating male connector. In addition, a connector locking piece 13 is provided on the side of connector 12, extending along the side toward the harness body 11.
[0037] As shown in Figure 2(a), the connector locking piece 13 comprises a locking base 131 that is spaced at a predetermined distance from the side surface of the connector 12 and extends along the side surface toward the harness body 11, and a convex portion 132 that protrudes from the locking base 131 toward the side surface of the connector 12.
[0038] The grommet 20 is a resin exterior component that protects the harness 10 routed between the vehicle body panel and the door panel by inserting it into the grommet body 30. It comprises a grommet body 30 through which the harness 10 is inserted, and an inner part 40 attached to one end of the grommet body 30 (see Figure 1).
[0039] The grommet body 30 has a substantially cylindrical tubular portion 31, a vehicle body side mounting portion 32 provided on one end of the tubular portion 31, and a door side mounting portion 33 provided on the other end of the tubular portion 31 (see Figure 1). The cylindrical portion 31 is a cylindrical body through which the harness 10 can be inserted, and has a flexible bellows structure in its central part. Therefore, the grommet 20 can bend in a desired direction to follow the opening and closing operation of the door panel.
[0040] The vehicle body mounting portion 32 is a cylindrical body provided on one end of the cylindrical portion 31 and is configured to allow the inner 40 to be attached. More specifically, as shown in Figure 2(b), the vehicle body mounting portion 32 has a predetermined thickness in the height direction H and has an outer edge portion 321 that is oval in shape when viewed from above. The outer edge portion 321 is formed with a recess facing outwards and has a concave portion 322 into which the first flange portion 53 and the second flange portion 62, which will be described later, can be fitted.
[0041] The vehicle body mounting portion 32, configured in this manner, is provided in a direction intersecting the longitudinal direction of the cylindrical portion 31, and together with the inner portion 40, it can be attached to the vehicle body panel by clamping it. This allows the grommet 20 to be held to the vehicle body panel, and the harness 10 to be routed along the grommet 20 in the desired direction.
[0042] The door-side mounting portion 33 is provided on the other end of the cylindrical portion 31 and can be attached to the door panel. This allows the grommet 20 to be held in place by the door panel, and the harness 10 to be routed between the vehicle body panel and the door panel.
[0043] As described above, the inner 40 is a grommet inner that can be attached to the vehicle body side mounting portion 32 provided at one end of the cylindrical portion 31, and together with the vehicle body side mounting portion 32, the grommet body 30 can be held to the vehicle body panel. More specifically, the inner 40 is a hollow, roughly cylindrical shape with a roughly oval shape having its major axis in the first direction L when viewed from above. A connector 12 is fixed to one end, and the harness body 11 can be inserted through it.
[0044] As shown in Figures 3(a) and 3(b), the inner 40 configured in this way comprises a first divided body 50 and a second divided body 60 that can be divided in the first direction L. The inner 40 also includes a locking portion 41 for locking and fixing the first divided body 50 and the second divided body 60 together.
[0045] As shown in Figures 3(a) and 3(b), the first divided body 50 corresponds to the front side LA of the inner body 40. More specifically, as shown in Figures 4(a), 4(b), and 4(c), the first divided body 50 has an upper surface portion 51 which is approximately semi-elliptical in plan view, a first outer peripheral wall 52 which extends downward HD from the outer edge portion of the upper surface portion 51, and a first flange portion 53 which extends outward from the lower end of the first outer peripheral wall 52.
[0046] As shown in Figures 4(a), 4(b), and 5(a), the upper surface portion 51 is a roughly flat plate with a roughly semi-elliptical shape in plan view, in which the arc portion protrudes slightly upward HU from the straight portion along the first direction L. The first outer peripheral wall 52 is a wall that extends downward HD along the outer edge of the upper surface portion 51 and constitutes a part of the outer peripheral surface of the inner 40. More specifically, as shown in Figures 4(a), 4(c), 5(a), and 5(b), the first outer peripheral wall 52 is a double wall composed of a first outer wall portion 521 along the outer edge of the upper surface portion 51 and a first inner wall portion 522 provided inside the first outer wall portion 521.
[0047] As shown in Figures 4(b), 4(c), and 5(a), the first outer wall portion 521 is an outer wall that extends a predetermined length downward HD from the outer edge of the upper surface portion 51. Furthermore, the first outer wall portion 521 is provided with an inwardly cut-out portion 523 at a position corresponding to the forward side LA of the boundary between the straight portion and the arc portion of the upper surface portion 51 (see Figures 4(b) and 5(b)).
[0048] As shown in Figures 4(c) and 5(a), the first inner wall portion 522 is an inner wall provided on the inside of the first outer wall portion 521, at a predetermined distance from the first outer wall portion 521. That is, openings are formed at the rear end LB of the first outer wall portion 521 and the first inner wall portion 522, allowing insertion in the first direction L (see Figure 5(b)).
[0049] Furthermore, as shown in Figures 5(a) and 5(b), a locking through hole 524 is provided in the first inner wall portion 522. The locking through-hole 524 is a through-hole in the first inner wall portion 522 that penetrates in the thickness direction near the end of the front side LA of the straight portion in plan view, and is roughly rectangular in shape in side view, and is provided in pairs on the left side WL and the right side WR.
[0050] The first outer wall portion 521, the first inner wall portion 522, and the locking through hole 524 configured in this way form a locking frame 54 having an opening that is inserted in the first direction L, as shown in Figures 4(a), 4(c), 5(a), and 5(b).
[0051] Furthermore, as shown in Figure 5(b), the first inner wall portion 522 is connected to the first outer wall portion 521 via a notched connecting portion 525 that extends outward at a position corresponding to the first complete cutout portion 523. The first inner wall portion 522 corresponding to the complete cutout portion 523 is provided with a first panel clamping piece 55 that extends outward from the upper end of the first inner wall portion 522.
[0052] The first panel clamping piece 55 extends outward from the upper end of the first inner wall portion 522 to a position corresponding to the first outer wall portion 521, and also extends downward towards HD from the position corresponding to the first outer wall portion 521. The central portion of the first panel clamping piece 55 protrudes so as to gradually bulge outward towards the downward HD. That is, the central portion of the first panel clamping piece 55 has an inclined surface that slopes outward towards the downward HD. The first panel clamping piece 55 configured in this way is configured to be able to elastically deform inward when an inward force is applied to the inclined surface.
[0053] The first flange portion 53 is a flange that is approximately oval in shape in plan view, projecting outward from the end of the lower HD of the first outer wall portion 521. The portion of the first flange portion 53 corresponding to the locking through hole 524 is cut out toward the first outer wall portion 521, and the portion corresponding to the first panel clamping piece 55 penetrates in the height direction H (see Figure 5(b)).
[0054] The upper surface portion 51, the first outer peripheral wall 52, and the first flange portion 53, configured in this way, form a bottomed concave shape with an opening on the lower side HD. A protruding wall 56 extending upward HU is provided at the rear end LB of the upper surface portion 51, spanning from one end to the other in the second direction W. Both ends of the protruding wall 56 are provided at positions corresponding to the first inner wall portion 522 on the upper surface portion 51.
[0055] A pair of plate-shaped protrusions 57 project from the protruding wall 56 toward the rear side LB. Specifically, the protrusions 57 are arranged at a predetermined distance from the locking frame 54, the rear side LB, and the upper side HU.
[0056] As shown in Figure 5(a), the projection 57 is a plate-like body with a roughly rectangular shape in side view, having a long side that is approximately the same length as the height H of the projection wall 56, along the height direction H, and a short side that is approximately the same length as the straight portion of the upper surface 51, along the first direction L. The projection 57 also has approximately the same plate thickness as the first inner wall 522. The tip of the projection 57 tapers towards the rear side LB, and the tip of the projection 57 and the end on the upper side HU are chamfered.
[0057] The protruding portion 57, configured in this way, protrudes slightly inward from both ends of the protruding wall 56 toward the rear side LB. More specifically, the protruding portion 57 is positioned inward from both ends of the protruding wall 56 in the second direction W for a length approximately equal to the thickness of the first inner wall portion 522.
[0058] The second divided body 60 corresponds to the rear side LB of the inner body 40 and, as shown in Figures 6 and 7, has a second outer peripheral wall 61 which is configured in a substantially semi-elliptical shape in plan view, and a second flange portion 62 which extends outward from the lower end of the second outer peripheral wall 61.
[0059] The second outer perimeter wall 61 is a wall that is erected along the height direction H and has a roughly oval shape in plan view, and constitutes a part of the outer perimeter surface of the inner 40. More specifically, the second outer perimeter wall 61 is a double wall composed of a second outer wall portion 611 that has a shape substantially symmetrical to the first outer wall portion 521, and a second inner wall portion 612 provided inside the second outer wall portion 611 (see Figure 7(b)).
[0060] The second outer wall section 611 has a shape that is substantially symmetrical to the first outer wall section 521. More specifically, the second outer wall section 611 is an outer wall that is semi-elliptical in plan view, with an opening on the front side LA and inserted along the height direction H. A second notch 613 is provided on the rear side LB of the boundary between the straight portion and the arc portion of the second outer wall section 611, which is semi-elliptical in plan view, and is cut out inward (see Figures 6(b) and 7(b)).
[0061] The second inner wall portion 612 is an inner wall provided on the inside of the second outer wall portion 611 at a predetermined distance. Furthermore, as shown in Figures 6(a) and 7(b), the front end LA of the second inner wall portion 612 is connected to the front end LA of the second outer wall portion 611 via a tip connecting portion 614.
[0062] Furthermore, the second inner wall portion 612 is connected to the second outer wall portion 611 via an intermediate connecting portion 615 and a rear connecting portion 616 at a position corresponding to the second notch portion 613. The second inner wall portion 612 corresponding to the second notch portion 613 is provided with a second panel clamping piece 63 that extends outward from the upper end of the second inner wall portion 612. Since the second panel clamping piece 63 has the same configuration as the first panel clamping piece 55, its explanation is omitted here.
[0063] The tip connecting portion 614 is a flat plate that connects the ends of the front side LA of the second outer wall portion 611 and the second inner wall portion 612 in the second direction W from one end to the other in the height direction H. That is, the width length of the tip connecting portion 614 (length along the second direction W) is equal to the distance between the second outer wall portion 611 and the second inner wall portion 612. As shown in Figures 6(a), 6(b), 7(a), and 7(b), a locking piece 64 that protrudes toward the front side LA is provided in the central part of the tip connecting portion 614 configured in this way.
[0064] As shown in Figures 7(a) and 7(b), the locking piece 64 comprises a through-locking portion 641 which is substantially rectangular in side view, and a locking projection 642 which has a projection that protrudes inward in the second direction W from the tip of the through-locking portion 641.
[0065] The insertion locking portion 641 is a plate-like body with a roughly rectangular shape in side view, having a long side that is approximately equal in length to the straight portion of the semi-elliptical second outer wall 61, and a short side that is approximately half the length of the height H in the second outer wall portion 611. The insertion locking portion 641 also has a thickness that is approximately equal to the spacing between the second outer wall portion 611 and the second inner wall portion 612. The long side of the insertion locking portion 641 is aligned with the first direction L, and the short side is aligned with the height direction H. Furthermore, the tip of the insertion locking portion 641 tapers towards the front side LA.
[0066] The locking projection 642 protrudes inward in the second direction W from the central portion in the height direction H of the insertion locking portion 641. More specifically, the locking projection 642 gradually protrudes inward in the second direction W as it moves from the tip of the insertion locking portion 641 toward the rear side LB. The length of the locking projection 642 in the first direction L is approximately equal to the length of the locking through hole 524 in the first direction L, and the maximum protrusion length of the locking projection 642 in the second direction W is approximately half the thickness of the second inner wall portion 612.
[0067] The locking piece 64 configured in this way is configured so that when the first divided body 50 and the second divided body 60 are assembled to form the inner body 40, the locking projection 642 can be locked into the locking through hole 524. In other words, the locking portion 41 that locks the first divided body 50 and the second divided body 60 is composed of a locking frame 54 and a locking piece 64.
[0068] Furthermore, the central portion of the rear LB in the second inner wall portion 612, more specifically, the space between the rear connecting portions 616 provided on the rear LB, is cut out. That is, the second inner wall portion 612, which is composed of a semi-elliptical shape in plan view, has the apex portion formed on the rear LB cut out in the thickness direction (see Figure 7(b)). The rear connecting portion 616 provided on the rear LB is formed in a fan shape when viewed from the bottom, having an outer surface parallel to the intermediate connecting portion 615 and an inner surface along the first direction L.
[0069] The second outer peripheral wall 61, configured in this way, is provided with a pair of extensions 65 that extend upward from the second inner wall portion 612 and the rear connecting portion 616 toward the upper side HU. As shown in Figures 6(a), 6(b), and 7(a), the extension portion 65 is integrally composed of an extension base portion 651 extending upward HU from the second inner wall portion 612 and the rear connecting portion 616, and an inward projection portion 652 that protrudes inward in the second direction W from the upper portion of the extension base portion 651.
[0070] The extended base portion 651 is a roughly plate-shaped wall extending upward HU from the second inner wall portion 612 and the rear connecting portion 616, and its length is approximately three times the length H in the height direction of the protruding wall 56. The portion of the extended base portion 651 corresponding to the rear connecting portion 616 is a flat plate shape parallel to the first direction L.
[0071] The inwardly projecting portion 652 protrudes from the second inner wall portion 612 by a height HU equal to the height H in the height direction of the projecting wall 56, and from the front side LA of the extending base portion 651 toward the inside in the second direction W, for a length approximately equal to the plate thickness of the projection portion 57. That is, the lower side HD of the inwardly projecting portion 652 forms an arrangement space S in which the projection portion 57 can be placed when the first divided body 50 and the second divided body 60 are locked together (see Figures 6(a) and 7(a)).
[0072] On the inner side of the extension portion 65 configured as described above, in the second direction W, there are a right extension wall 66 and a left extension wall 67, both made of flat plates. The right-side extension wall 66 is provided on the left-side WL of the inward projection 652 of the right-side WR. More specifically, the right-side extension wall 66 is a flat plate along the first direction L and the height direction H that connects the portion of the extension base 651 of the right-side WR that extends upward HU from the rear connecting portion 616 to the inward projection 652. The right-side extension wall 66 also protrudes slightly beyond the front-side LA end of the inward projection 652 and beyond the rear-side LB end of the second outer wall portion 611. Here, the portion that protrudes forward LA from the inward projection 652 is referred to as the right-side projection 661. Furthermore, the portion of the right-side extension wall 66 that protrudes towards the rear-side LB from the second outer wall portion 611 is inclined toward the upward HU (see Figure 7(a)).
[0073] The left extension wall 67 is provided on the right WR of the inward projection 652 of the left WL, facing the right extension wall 66. More specifically, the left extension wall 67 is a flat plate along the first direction L and the height direction H that connects the portion of the extension base 651 of the left WL that extends upward HU from the rear connecting portion 616 to the inward projection 652. The left extension wall 67 also protrudes slightly beyond the front LA end of the inward projection 652 and beyond the rear LB end of the second outer wall portion 611. Here, the portion that protrudes forward LA from the inward projection 652 is referred to as the left projection 671.
[0074] The length L in the first direction of the left projection 671 is shorter than the length of the locking piece 64 extending from the tip connecting portion 614, and is approximately equal to the length L in the first direction of the right projection 661 (see Figures 6(b) and 7(b)). Also, the thickness of the left extension wall 67 is approximately equal to the distance between the locking base 131 and the side surface of the connector 12.
[0075] The portion of the left extension wall 67 that protrudes towards the rear LB side beyond the second outer wall portion 611 is inclined toward the upward HU side, similar to the right extension wall 66. More specifically, the left extension wall 67 is a flat plate with a thickness equal to the distance between the side surface of the connector 12 and the connector locking piece 13, and extends further toward the rear LB and upward HU side than the portion of the right extension wall 66 that protrudes toward the rear LB side (see Figures 6(a) and 6(b)). The tip of the left extension wall 67 configured in this way is provided with a locking hole 672 for sliding the connector locking piece 13 to lock and secure the connector 12 (see Figure 6(b)).
[0076] With the left-side extension wall 67 configured in this way, the connector 12 can be locked and fixed to the left-side extension wall 67 by sliding the connector locking piece 13 along the left-side extension wall 67 and engaging the convex portion 132 in the locking hole 672 (see Figure 1).
[0077] The second flange portion 62 is a flange that is approximately oval in shape in plan view, projecting outward from the end of the lower HD on the second outer wall portion 611. The portion of the second flange portion 62 sandwiched between the right extension wall 66 and the left extension wall 67 is cut out toward the second outer wall portion 611 (see Figure 7(b)).
[0078] The second divided body 60, composed of the second outer peripheral wall 61 and the second flange portion 62, has an opening on the front side LA and is a roughly columnar body with a semi-elongated bottom surface that is inserted in the height direction H. By locking and fixing it with the first divided body 50, it forms the inner body 40 as shown in Figure 8.
[0079] More specifically, the first divided body 50 and the second divided body 60 can be locked and fixed in place by inserting the locking piece 64 into the locking frame 54 to form the inner body 40 (see Figure 8(a)). In the inner body 40 locked and fixed to the first divided body 50 and the second divided body 60 in this way, the protruding portion 57 that protrudes from the protruding wall 56 toward the rear side LB is positioned along the inside of the extension base 651 in the second direction W and in the arrangement space S formed directly below the inward protruding portion 652 (see Figure 8(b)). In addition, the rightward protruding portion 661 and the leftward protruding portion 671 that protrude toward the front side LA from the right extension wall 66 and the left extension wall 67 provided on the inside of the extension base 651 in the second direction W are positioned directly above the protruding wall 56 which is provided along the second direction W (see Figure 8(b)).
[0080] The inner 40 configured in this way can be assembled to the harness 10 routed inside the grommet body 30. Specifically, the second divided body 60 is positioned at a desired location on the harness 10 so that the harness 10 is aligned with the inner surface of the second outer wall 61. Next, the first divided body 50 is positioned so that the locking frame 54 faces the locking piece 64 of the second divided body 60 positioned at the desired location on the harness 10, and the first divided body 50 is moved toward the second divided body 60. As a result, the locking piece 64 is inserted into the locking frame 54, and the protruding portion 57 is guided into the arrangement space S along the extended base portion 651.
[0081] Then, by moving the first divided body 50 further toward the second divided body 60, the locking projection 642 is locked into the locking through hole 524, and an inner 40 can be formed in which the first divided body 50 and the second divided body 60 are locked and fixed at a desired position on the harness 10. In addition, the rightward projection 661 and the leftward projection 671 are positioned directly above the projection wall 56 provided in the second direction W. The inner 40 through which the harness 10 is inserted can be attached to the vehicle body side mounting portion 32 provided on one end of the cylindrical portion 31.
[0082] Here, the vehicle body mounting portion 32 is provided in a direction intersecting the longitudinal direction of the cylindrical portion 31 (see Figure 9). Therefore, when the harness 10, which is inserted into the inside of the cylindrical portion 31, is inserted into the inner 40, the harness 10 is curved towards the front side LA. On the other hand, since the harness 10, which has a predetermined rigidity, tries to maintain a straight shape, the harness 10 inserted into the cylindrical portion 31 along a direction intersecting the height direction H may press against the protruding wall 56 in the inner 40 towards the front side LA. (See Figure 9)
[0083] Thus, the external force F caused by the forward pressure LA of the harness 10 acts on the protruding wall 56, and a force acts on the first divided body 50 to rotate relative to the second divided body 60 in a direction that separates it from the locking portion 41, where the locking frame 54 and the locking piece 64 are locked, with the locking portion 41 as the fulcrum (see Figures 9 and 10).
[0084] However, when the first divided body 50 rotates relative to the front side LA with the locking portion 41 as the pivot point, the upper end surface of the projection 57 located in the arrangement space S comes into contact with the lower end surface of the inward projection 652 (see Figure 10). As a result, the projection 57 and the inward projection 652 can restrict the relative rotation of the first divided body 50 with the locking portion 41 as the pivot point.
[0085] Furthermore, the extended base portion 651, which is positioned on the outside of the plate-shaped projection portion 57 in the second direction W, comes into contact with the projection portion 57 when the first divided body 50 is twisted in the second direction W due to the relative rotation of the first divided body 50 with the locking portion 41 as a fulcrum. Therefore, the extended base portion 651 can restrict the twisting of the first divided body 50 relative to the second divided body 60.
[0086] Furthermore, since the protruding portion 57 is spaced apart from the locking frame 54, which acts as the pivot point for rotation, and from the rear LB and the upper HU, it rotates sufficiently toward the rear LB even with a slight rotation angle of the first divided body 50 with the locking portion 41 as the rotation center, thus allowing for precise control of the relative rotation of the first divided body 50.
[0087] Similarly, as the first divided body 50 and the second divided body 60 rotate relative to each other, the protruding wall 56 provided on the first divided body 50, which rotates with the locking portion 41 as a pivot point, comes into contact with the right protruding portion 661 and the left protruding portion 671 (see Figure 10). As a result, the right protruding portion 661 and the left protruding portion 671 and the protruding wall 56 can restrict the relative rotation of the first divided body 50.
[0088] Thus, the grommet 20 comprises a cylindrical grommet body 30 through which the harness 10 is routed, and an inner 40 attached to one end of the grommet body 30 to hold the grommet body 30 to the panel. The grommet body 30 is equipped with a vehicle-side mounting portion 32 to which the inner 40 is attached and which is attached to the panel. The inner 40 is equipped with a first divided body 50 and a second divided body 60 that can be divided in a first direction L perpendicular to the upper side HU that attaches the vehicle-side mounting portion 32 to the panel, and a locking portion 41 that locks and fixes the first divided body 50 and the second divided body 60 together. The first divided body 50 has a protruding wall 56 that is pressed in a direction away from the second divided body 60 (forward side LA) by the harness 10 through which it is inserted. Furthermore, the first divided body 50 and the second divided body 60 are provided with protrusions 57 and inward-facing protrusions 652, as well as the protrusion wall 56 and rightward protrusions 661 and leftward protrusions 671, which restrict the relative rotation of the first divided body 50 and the second divided body 60 with respect to the locking portion 41 which is spaced apart from each other, by the protrusion wall 56 pressing against them. The protrusions 57 and inward-facing protrusions 652, as well as the protrusion wall 56 and rightward protrusions 661 and leftward protrusions 671 are provided at a predetermined distance from the locking portion 41. The grommet-equipped harness 1 is equipped with a grommet 20 and a harness 10 routed inside the grommet 20.
[0089] The grommet 20, inner 40, and grommet-equipped harness 1 configured in this way can restrict relative rotation between the first divided body 50 and the second divided body 60 with the locking portion 41 as the pivot point. More specifically, because the harness 10 has a predetermined rigidity, when the harness 10 inserted through the grommet 20 is routed toward the side of the first split body 50 (front side LA) relative to the second split body 60, the harness 10 may press against the protruding wall 56 provided on the first split body 50. When the harness 10 presses against the protruding wall 56 in this way, an external force F acts on the first split body 50, causing the first split body 50 and the second split body 60 to rotate relative to each other with the locking portion 41 as the pivot point, so that they separate from each other. However, the protruding portion 57 and the inwardly protruding portion 652, which are provided at a predetermined distance from the locking portion 41, as well as the protruding wall 56 and the rightward protruding portion 661 and leftward protruding portion 671, can restrict the relative rotation of the first split body 50 and the second split body 60 with the locking portion 41 as the pivot point. Therefore, separation between the first split body 50 and the second split body 60 can be suppressed.
[0090] Furthermore, the protruding portion 57 and the inwardly inwardly inwardly inwardly inwardly inwardly inwardly inwardly in front of the locking portion 41, as well as the protruding wall 56 and the rightwardly inwardly inwardly inwardly inwardly inwardly inwardly inwardly inwardly inwardly inwardly in front of the locking portion 41, and the protruding wall 56 and the rightwardly inwardly inwardly inwardly inwardly in front of the locking portion 41, and the protruding wall 56 and the rightwardly inwardly inwardly inwardly in front of the leftwardly inwardly in front of the locking portion 41, and the protruding wall 56 and the rightwardly inwardly inwardly inwardly in front of the leftwardly inwardly in front of the locking portion 41, and the protruding portion 57 and the inwardly portion 57 and the rightwardly inwardly inwardly inwardly in front of the locking portion 41, and the protruding portion 57 and the rightwardly inwardly inwardly inwardly in front of the locking portion 41, and the protruding portion 57 and the rightwardly inwardly inwardly in front of the locking portion 41, and the protruding portion 57 and the protruding portion 671, and the protruding portion 671, and the protruding portion 671, and the protruding portion 671, and the protruding portion 671, and the protruding portion
[0091] Furthermore, the device includes a projection 57 that extends from the first divided body 50 toward the second divided body 60, and an inward projection 652 provided on the second divided body 60 that, by rotating with a locking portion 41 that separates the first divided body 50 and the second divided body 60 as a pivot point, contacts and restricts at least the end face of the projection 57 along the first direction L.
[0092] This allows for a simple structure in which the protruding portion 57 extending from the first divided body 50 toward the second divided body 60 is brought into contact with the inwardly protruding portion 652 provided on the second divided body 60, thereby restricting the relative rotation between the first divided body 50 and the second divided body 60.
[0093] Furthermore, the protruding portion 57 that extends from the first divided body 50 toward the second divided body 60 is positioned inside the second divided body 60 when the first divided body 50 and the second divided body 60 are locked and fixed together. This prevents the protruding portion 57 from interfering with and being damaged by other externally positioned components. Therefore, relative rotation with the locking portion 41 between the first divided body 50 and the second divided body 60 as a fulcrum can be reliably restricted.
[0094] Furthermore, the protrusion 57 provided on the first divided body 50, which has a protruding wall 56 that is pressed against the harness 10, and the inwardly protruding portion 652 provided on the second divided body 60, which is not pressed against the harness 10, can restrict relative rotation of the first divided body 50 and the second divided body 60 with the locking portion 41 as the pivot point.
[0095] Furthermore, the protruding wall 56 is provided so as to span the upper side HU of the first divided body 50, which is opposite to the panel when attached to the panel, and the second direction W is perpendicular to the upper side HU and the first direction L, and the protruding portion 57 protrudes in pairs from both ends of the protruding wall 56 in the second direction W.
[0096] This allows the relative rotation of the first divided body 50 caused by the harness 10 pressing against the protruding wall 56 to be restricted by the pair of protruding portions 57 and the inwardly protruding portion 652 that abuts against the protruding portion 57. Therefore, the relative rotation of the first divided body 50 and the second divided body 60 with the locking portion 41 as the pivot point can be restricted stably and reliably.
[0097] Furthermore, the protruding portion 57 protrudes from both ends in the second direction W of the protruding wall 56, which is outside the routing path of the harness 10 that passes through the central portion. Therefore, the distance between the harness 10 that passes through the central portion and the protruding wall 56 can be maintained, and the harness 10 can be prevented from pressing against the protruding wall 56. Consequently, relative rotation with the locking portion 41 between the first divided body 50 and the second divided body 60 as the pivot point can be suppressed.
[0098] Furthermore, since the protruding portion 57 is configured as a plate along the upper side HU, the strength of the protruding portion 57 can be improved. As a result, relative rotation with the locking portion 41 between the first divided body 50 and the second divided body 60 as a fulcrum can be more reliably restricted. This makes it possible to form an inner 40 in which the first divided body 50 and the second divided body 60 are locked together in the desired state, and to properly fix the inner 40 to the vehicle body side mounting portion 32.
[0099] Furthermore, since the plate-shaped protrusion 57 is provided on the protruding wall 56, the strength of the protruding wall 56 can also be improved. Therefore, damage to the protruding wall 56 due to pressure from the harness 10 can be suppressed.
[0100] Furthermore, the locking portion 41 is composed of a locking piece 64 provided on the second divided body 60 and extending toward the first divided body 50, and a locking frame 54 provided on the first divided body 50 into which the locking piece 64 is inserted and locked. The protruding portion 57 is positioned on the upper side HU, which is opposite to the panel side of the locking piece 64, when the first divided body 50 and the second divided body 60 are locked together.
[0101] This allows the distance from the position where the locking piece 64 and the locking frame 54 are locked to the point of contact between the protruding portion 57 and the inwardly facing protruding portion 652 to be set to be longer. As a result, even with a small relative rotation angle of the first divided body 50 with the locking portion 41 as the pivot point, the protruding portion 57 and the inwardly facing protruding portion 652 can be brought into contact, and the relative rotation of the first divided body 50 and the second divided body 60 with the locking portion 41 as the pivot point can be restricted with greater precision. Therefore, separation between the first divided body 50 and the second divided body 60 can be more reliably suppressed, and gaps between the first divided body 50 and the second divided body 60 can be more reliably suppressed.
[0102] Furthermore, the protruding wall 56 is a plate-like structure that spans the upper HU of the first divided body 50, which is on the opposite side of the panel when attached to the panel, and the second direction W which intersects the upper HU and the first direction L. The second divided body 60 is provided with a rightward protrusion 661 and a leftward protrusion 671 that protrude toward the first divided body 50 and contact at least the end face of the upper HU on the opposite side of the panel of the protruding wall 56 by rotation around the locking portion 41 of the first divided body 50 and the second divided body 60 as a fulcrum, such that the first divided body 50 and the second divided body 60 are separated from each other.
[0103] This makes it possible to restrict relative rotation between the first divided body 50 and the second divided body 60 with the locking portion 41 as the pivot point. More specifically, the right protrusion 661 and the left protrusion 671 protrude from the second divided body 60 toward the side of the first divided body 50 (front side LA), and are provided at a predetermined distance from the locking portion 41. Therefore, as the first divided body 50 rotates relative to the locking portion 41 with the locking portion 41 as the pivot point, the right protrusion 661 and the left protrusion 671 can be brought into contact with the end face of the upper side HU on the protruding wall 56 provided on the first divided body 50, which is opposite to the side with the panel. Thus, the relative rotation between the first divided body 50 and the second divided body 60 with the locking portion 41 as the pivot point can be restricted.
[0104] Furthermore, the second segmented body 60 is provided with a left-side extension wall 67 for fixing the connector 12 attached to one end of the harness 10, thereby securing the harness 10 inserted through the grommet body 30. This prevents unintended movement of the harness 10, for example, during transportation. Consequently, it is possible to suppress the harness 10 from pressing against the protruding wall 56.
[0105] In the correspondence between the structure of this invention and the embodiments described above, The wire harness of this invention corresponds to the harness 10 of the embodiment, and similarly, The grommet body is compatible with grommet body 30, The grommet inner is compatible with inner 40.

The protruding contact portion corresponds to the right protrusion 661 and the left protrusion 671. The connector fixing part corresponds to the left extension wall 67, The grommet harness corresponds to grommet harness 1, but this invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.
[0106] For example, in this embodiment, the first divided body 50 is provided with a protrusion 57 and the second divided body 60 is provided with an inward-facing protrusion 652, but this structure is not necessarily required. For example, the second divided body 60 may be provided with a structure corresponding to the protrusion 57 and the first divided body 50 may be provided with a structure corresponding to the inward-facing protrusion 652. Alternatively, both the first divided body 50 and the second divided body 60 may be provided with a pair of protrusions 57 and inward-facing protrusions 652.
[0107] Furthermore, the first divided body 50 and the second divided body 60 may be configured to be further divisible in areas not pressed by the harness 10. In other words, the inner 40 may be divided into two or more parts.
[0108] Furthermore, in this embodiment, the protruding portion 57 and the inwardly directed protruding portion 652 are structured so that when the first divided body 50 and the second divided body 60 rotate relative to each other, the end face of the protruding portion 57 along the first direction L and the inwardly directed protruding portion 652 come into contact with each other, but the embodiment is not limited to this. For example, when the first divided body 50 and the second divided body 60 are locked and fixed together, the end face of the protruding portion 57 along the first direction L and the inwardly directed protruding portion 652 may come into contact with each other.
