[0003]

[Problems to be solved by the device]

 At the time of mounting the grommet 1 to which the wire harness has been penetrated in advance on the vehicle body panel 2, the panel flat portion 1c is pulled out to the outer side Y from the inner side X of the panel 2 through the pull-out hole 2a, and at the same time, It is necessary to lock the entire circumference of the locking recess 1b of the panel mounting portion 1a with the inner circumference of the extraction hole 2a.

Since the grommet is attached to the panel when the grommet is attached to the panel parallel portion 1c pulled out to the outside Y of the panel as shown in FIG. The pulling direction L1 is different from the axial direction L2 of the drawing hole 2a, and the panel mounting portion 1a is pulled while being inclined with respect to the drawing hole 2a. Therefore, it is not easy to lock the entire circumference of the locking recess 1b of the panel mounting portion 1a to the inner circumference of the extraction hole 2a.

That is, on the Z1 side in the pulling direction in which the panel parallel portion 1c projects, the locking recess 1b easily locks on the inner peripheral surface of the extraction hole 2a, but on the Z2 side on the opposite side, the locking recess 1b. Does not easily engage with the drawing hole 2a.

In order to facilitate the work of mounting the L-shaped grommet on the panel, a grommet shown in FIG. 7 is proposed in Japanese Utility Model Laid-Open No. 1-68627. In the grommet 1 ', the panel side 1c'-2 of the panel parallel portion 1c' is thin and the non-panel side 1c'-1 is thick. However, even in the above-mentioned grommet, since the panel parallel portion 1c ′ is gripped and pulled when mounted on the panel, the panel mounting portion 1a ′ is inclined with respect to the panel drawing hole 2a, and the opposite side Z2 from the pulling direction is locked. The drawback that the recess 1b 'is difficult to lock in the extraction hole 2a has not been solved.

The present invention has been made in view of the above-mentioned problems, and a locking recess provided on the outer periphery of the panel mounting portion of the L-shaped grommet is easily and securely provided on the entire inner periphery of the drawing hole of the vehicle body panel. The part that is pulled out to the outside of the vehicle body panel can be pulled so that the grommet can be locked in place. Therefore, the purpose is to eliminate the problem that occurs when mounting the grommet panel.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a wire harness through-hole extending from the panel mounting portion, which has an annular locking recess on its outer peripheral surface, to the panel parallel portion, which is bent into an L shape. In the grommet provided with, a pulling protrusion that is protruded outward is provided at an outer surface portion of the panel mounting portion that is pulled out to the outside of the panel at substantially the same position as the central axis of the annular locking recess. It provides a special grommet.

The panel mounting part of the grommet has substantially the same shape as the drawing hole of the vehicle body panel to be mounted. When the drawing hole is circular, the outer surface part of the panel mounting part is a circular shape slightly curved outward, An annular panel locking portion is provided so as to project from the inner surface side peripheral edge thereof, and a locking recess is formed in the panel locking portion, while the pulling protrusion is externally provided at the center position of the circular outer surface portion. It is projected toward. The panel parallel portion is provided so as to protrude from one side portion of the outer surface portion of the panel mounting portion in a direction substantially perpendicular to the pulling projection portion.

The pulling protrusion is provided for an operator to grip and pull by hand when the grommet is attached to the panel, and its shape is arbitrary. For example, as a rod-shaped body having a circular cross section, a rib having a large diameter is provided at the tip of the rod-shaped body to prevent the hand from coming off. Alternatively, the outer peripheral surface of the rod-shaped body may be provided with irregularities or may have a polygonal cross section so as to have an anti-slip action when gripping. The rod-shaped body may be solid or hollow. The amount of protrusion of the above-mentioned pulling protrusion may be such that it can be grasped and pulled by hand.

[0011]

[Action]

 With the grommet of the present invention, when mounting in the panel pull-out hole, first the panel parallel part is pulled out to the outside of the panel through the pull-out hole, and then the pulling protrusion that protrudes from the outside of the panel mounting part pulled out to the panel outside side. Grasp the part and pull it outward. Since the pulling protrusion is provided at the center of the locking recess, when the pulling protrusion is pulled, the locking recess is not inclined but is pulled in a state of being substantially concentric with the panel drawing hole. As a result, the entire circumference of the locking recess can be locked to the entire inner circumference of the panel drawing hole substantially at the same time.

[0012]

【Example】

 The present invention will be described below with reference to the embodiments shown in the drawings. As shown in FIG. 1 and FIG. 2, the grommet 10 of the present invention has a panel mounting portion 11, a panel parallel portion 12 and a pulling protrusion 13 integrally formed of rubber.

The panel mounting portion 11 has a circular outer surface portion 11a that is slightly curved outward, and an annular panel locking portion 11b that protrudes from the inner peripheral edge of the circular outer surface portion 11a. A locking recess 11c is formed in an annular shape on the outer surface of the stopper 11b. The panel parallel portion 12 has a cylindrical shape, and is protruded from one side portion of the outer surface portion 11a of the panel mounting portion 11 by being bent in an L shape so that the hollow portion 12a is continuous with the inner hollow portion 11d of the panel mounting portion 11. The wire harness penetration portion 14 is formed.

The pulling protrusion 13 is provided so as to protrude outward from the center position of the outer surface portion 11 a of the panel mounting portion 11. Therefore, the direction is orthogonal to the panel parallel portion 12. The pulling protrusion 13 is in the shape of a solid round bar, and a rib 13a having a large diameter is provided at the tip thereof.

As shown in FIG. 3, the grommet 10 having the above-described configuration is in a state in which the wire harness W is preliminarily penetrated through the wire harness through hole 14 provided so as to penetrate from the panel mounting portion 11 to the panel parallel portion 12. The panel 20 is attached by pulling it out from the inner side X to the outer side Y through the pull-out hole 21 of the panel 20.

At the time of the above-mentioned mounting work, first, as shown in FIG. 3A, the panel parallel portion 12 is grasped, and the panel parallel portion 12 is pulled out to the outside Y through the extraction hole 21. When the pulling protrusion 13 of the panel mounting portion 11 is pulled out to the outside Y in the above work, as shown in FIG. 3B, the pulling protrusion 13 is gripped to be the same as the axis L2 of the pull-out hole 21. Pull outward in the direction as indicated by the arrow.

As described above, when pulling in the same direction as the axis of the drawing hole 21, the axis of the panel locking portion 11b of the panel mounting portion 11 is pulled in line with the axis of the drawing hole 21, and thus the panel locking portion is pulled. 11b is attached to the drawing hole 21 without tilting, and the locking recess 11c on the outer peripheral surface of the panel locking portion 11b can be locked on the inner peripheral surface of the drawing hole 21 at substantially the same time, as shown in FIG. The grommet 10 is securely attached to the panel drawing hole 21.

It should be noted that the pulling protrusion 13 that protrudes outward from the panel mounting portion 11 is made of rubber and an integral piece of rubber, and therefore is easily bent. Therefore, when arranging the exterior material on the outside of the panel 20, the pulling protrusion 13 does not bend and become an obstacle.

The pulling protrusion 13 may have a cylindrical shape as shown in FIG. 4A, a shape having irregularities on the outer peripheral surface as shown in FIG. 4B, or a horizontal cross section of a polygonal shape. Any shape that can be gripped and pulled can be used.

[0020]

[Effect of device]

 As is clear from the above description, in the grommet according to the present invention, the pulling protrusion is provided on the outer surface of the panel mounting portion at substantially the same position as the central axis position of the locking recess. By grasping and pulling, you can pull the panel mounting part without tilting it to the panel drawing hole. Therefore, the locking recess provided in the panel mounting portion can be locked easily and reliably with respect to the panel drawing hole.
