  In consideration of the above fact, the present invention provides a member mounting structure capable of penetrating a penetrating member between mounted members while suppressing the occurrence of a gap between the mounted member and the filler with the mounted members attached to each other. It is a problem to obtain.

In the first aspect of the present invention, a filler filled between a plurality of attached members, and a trapezoidal shape whose cross-sectional shape extends toward one of the attached members, the penetrating member is penetrated. And the penetrating auxiliary means embedded in the filler so that the penetrating member traverses between the plurality of mounted members, and the penetrating auxiliary means is provided to contact at least one of the mounted members. And an interval maintaining means for maintaining an interval between the attached member and the penetration assisting means.

  In the present invention, a filler is filled between a plurality of attached members, and these gaps are filled. The members to be attached are attached to each other by this filler or using another adhesive or the like. Further, a penetration assisting unit through which the penetrating member penetrates is embedded in the filler, and the penetrating member penetrates between a plurality of attached members.

Here, the penetration assisting means is provided with a spacing maintaining means, and this spacing maintaining means contacts at least one of the mounted members to maintain the spacing between the mounted member and the penetration assisting means. For this reason, while the inclination of a penetration auxiliary member is prevented, generation | occurrence | production of the clearance gap between a to-be-attached member and a filler is suppressed.
Moreover, the penetration assisting means has a trapezoidal cross section, and the cross sectional shape extends toward one of the attached members. Therefore, since the filler filled between the mounted members reaches the mounted member along the trapezoidal slope, generation of a gap between the mounted member and the adhesive can be more effectively suppressed.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the spacing maintaining means is a convex part protruding from the penetration assisting means.

  In this way, by providing the convex portion as the gap maintaining means, only the tip of the convex portion makes point contact with the attached member, and the gap between the portion where the convex portion of the penetration assisting means is not formed and the attached member is filled. An agent enters and the generation of a gap between them can be suppressed.

According to a third aspect of the present invention, in the second aspect of the present invention, the convex portion is provided on a wide surface of the penetration assisting means having a trapezoidal cross section .

Therefore, the convex portion provided on the wide surface comes into contact with one of the attached members, so that the interval between the wide surface of the penetration assisting means and the attached member, that is, the filling interval of the filler can be kept constant, Generation | occurrence | production of the clearance gap between a to-be-attached member and an adhesive agent can be suppressed more effectively.

  The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the penetrating member is provided in the penetrating assisting unit, and the penetrating member has at least one edge of the attached member. It has an interference preventing means for preventing interference.

  The interference preventing means can prevent interference between at least one edge of the attached member and the penetrating member.

  In addition, this eliminates the need to ensure a wide interval between the mounted member and the penetrating member in consideration of interference prevention, so that the thickness of the filler can be reduced. Thereby, it can suppress more effectively that a penetration auxiliary means inclines.

  In the invention according to claim 5, in the invention according to any one of claims 1 to 4, one of the attached members is a vehicle body panel, and the other of the attached members is glass, The penetrating member is an electric wire.

  Accordingly, it is possible to suppress the generation of a gap between the glass or the vehicle body panel and the filler between them and allow the electric wire to pass between them.

  Since this invention set it as the said structure, it becomes possible to penetrate a penetration member between to-be-attached members, suppressing generation | occurrence | production of the clearance gap between an attached to-be-attached member and a filler in the state which attached to-be-attached members.

  The member attachment structure 12 to which the wire harness 20 which concerns on one Embodiment of this invention is applied is shown by FIG.1, FIG3 and FIG.4. Moreover, the wire harness 20 is shown by FIG. This member attachment structure 12 is applied when attaching glass 18 to an opening 16 formed in a vehicle body panel 14 of an automobile. As shown in FIG. 3, urethane 22 is filled between the glass 18 and the vehicle body panel 14. The member mounting structure 12 is applied when the urethane wire 22 is caused to cross the electric wire 24 and penetrate the vehicle interior 26 and the vehicle exterior 28.

  As shown in detail in FIGS. 2A to 2C, the wire harness 20 is made of resin and has a block shape as a whole, and the two end faces 30T are trapezoidal (and thus the cross section is also trapezoidal). An auxiliary unit 30 is provided. In particular, in the present embodiment, the end surface 30T has an isosceles trapezoidal shape. And in the use state of the wire harness 20, as shown in FIG. 3, as for the penetration auxiliary | assistant part 30, the wide surface 30W corresponding to the lower base of a trapezoid opposes the glass 18, and the narrow surface 30N corresponding to an upper base is shown. It arrange | positions so that the vehicle body panel 14 may be opposed. In this state, the wide surface 30 </ b> W and the glass 18 are bonded by urethane 32.

As shown in FIGS. 2 and 3, a plurality of dowels 34 (a total of five in the present embodiment, one in the center and one in the vicinity of the four corners) project from the wide surface 30 </ b> W. Yes. The dowel 34 protrudes from the wide surface 30W in a columnar shape or a conical shape, and the tip 34T is rounded into a hemisphere. The tips 34T of the five dowels 34 are formed so as to be positioned exactly on the same plane, and all of the tips 34T are in point contact with the glass 18. Thereby, the inclination of the wire harness 20 with respect to the glass 18 is prevented, and the variation in the position in the height direction (arrow H1 direction) is eliminated.

  Urethane 22 is also filled between the narrow surface 30N and the vehicle body panel 14, and the gap between the wire harness 20 and the vehicle body panel 14 is filled with the urethane 22. In particular, in the present embodiment, the urethane 22 is made of the same material as the urethane 32 used for bonding the wide surface 30 </ b> W and the glass 18.

  From the trapezoidal end surface 30T of the penetration assisting part 30, a substantially cylindrical interference preventing part 36 is extended in a direction away from each other, and the electric wire 24 is extended from one interference preventing part 36 to the penetration assisting part. Through 30, the other interference prevention unit 36 is penetrated. The interference prevention part 36 is set lower than the height H1 of the penetration assisting part 30 in the vicinity of the penetration assisting part 30, and when the wire harness 20 is disposed between the glass 18 and the vehicle body panel 14, it is inadvertent. Although it does not come into contact with the glass 18 or the vehicle body panel 14, the diameter is larger than that of the electric wire 24 as shown in FIG. As a result, as shown in FIG. 1, the wire 24 is prevented from interfering with the peripheral portion 18E of the glass 18 or the peripheral portion 14E of the vehicle body panel 14 when the wire harness 20 is in use.

  In the member mounting structure 12 using the wire harness 20 having such a configuration, as shown in FIG. 3, by causing the urethane 32 to act as an adhesive, the wide surface 30 </ b> W faces the glass 18. The wire harness 20 is bonded to the glass 18. Since the tip 34T of the dowel 34 contacts the glass 18, the wire harness 20 is positioned in the height direction (arrow H1 direction). Further, for example, even when a force is applied to the electric wire 24 or the like, inadvertent inclination or rattling of the wire harness 20 is prevented.

  In this state, as shown in FIGS. 3 and 4, urethane 22 is disposed between the narrow surface 30 </ b> N of the penetration assisting portion 30 and the vehicle body panel 14, and between the glass 18 and the vehicle body panel 14. Thereby, the clearance gap between the penetration auxiliary | assistant part 30 and the vehicle body panel 14, and the clearance gap between the glass 18 and the vehicle body panel 14 are filled with the urethane 32, and the distribution | circulation of the gas and liquid between these is blocked | prevented. As a result, the wire harness 20 is embedded in the urethane 32, and the electric wire 24 penetrating the wire harness 20 straddles the urethane 32 and penetrates the vehicle interior 26 and the vehicle exterior 28. Note that a peripheral molding 38 and a cover member 40 are disposed between the glass 18 and the vehicle body panel 14 as necessary, and the flow of gas or liquid between them is more reliably prevented.

  Here, in this embodiment, since the dowel 34 contacts the glass 18 and the inadvertent inclination or rattling of the wire harness 20 is prevented, the interval between the penetration assisting portion 30 and the glass 18, that is, the urethane 22, The filling interval of 32 can be kept constant, and the occurrence of pinholes in the urethane 22 and 32 can be suppressed.

  Further, since the penetration assisting portion 30 of the present embodiment has a trapezoidal end surface 30T, as shown in FIGS. 1, 2B, 3C, and 3, it extends from the narrow surface 30N to the wide surface 30W. The slope 30S exists, and at the time of filling the urethane 22, the urethane 32 is filled and applied along the slope 30S. Therefore, the occurrence of a so-called pinhole (a minute region in which the urethane 22 is not filled) between the urethane 22 and the glass 18 is also prevented. For example, as shown in FIG. 5 as a comparative example, when considering a penetrating auxiliary portion 50 having a rectangular end face (rectangular shape), the penetrating auxiliary portion 50 has a vertical surface 50S perpendicular to the glass 18 instead of the slope 30S. Therefore, there is a high possibility that pinholes are generated in the vicinity region E1 and the like with the glass 18. However, this possibility is low in the present embodiment.

  Moreover, in the present embodiment, the urethane 32 and the urethane 22 are made of the same material. Therefore, compared with what comprised these from dissimilar materials, the adhesiveness and compatibility of urethane 22 and 32 become high, and since generation | occurrence | production of the pinhole between these can also be prevented effectively, reliability improves. .

  Moreover, since the interference prevention part 36 is formed in the wire harness 20 of this embodiment, interference with the peripheral part 18E of the electric wire 24 and the glass 18, and the peripheral part 14E of the vehicle body panel 14 is prevented. Thereby, damage of the electric wire 24 etc. are also prevented. And, in order to prevent the electric wire 24 from interfering with the vehicle body panel 14 or the like, it is not necessary to make a large space between them, so that the thickness of the urethane 22 as the filler can be reduced. As a result, the inclination of the penetration assisting part 30 can be more reliably suppressed.

  In the above description, the dowel 34 whose tip 34T is hemispherical is given as the convex portion of the present invention. However, the convex portion is not limited to this, and may be a dowel whose tip is in surface contact with the glass 18, for example. . The number of dowels 34 is not limited, but if at least three dowels 34 are formed, the plane is determined by the tips of the three dowels, which is preferable from the viewpoint of preventing the wire harness 20 from tilting. When four or more dowels are formed, the tips of all the dowels may be positioned on the same plane. The plurality of dowels are preferably arranged symmetrically or not excessively unevenly in correspondence with the shape of the wire harness 20 when viewed in the normal direction of the glass 18.

  Further, the dowels can be formed not only on the side that contacts the glass 18 but also on the body panel 14. Thereby, careless inclination and rattling of the wire harness 20 with respect to the vehicle body panel 14 are prevented. In other words, since the relationship between the body panel 14 and the glass 18 that are the two attached members is relative, it may be configured to prevent the wire harness 20 from tilting or rattling based on either of them. (That is, a dowel that contacts the body panel 14 and a dowel that contacts the glass 18 is provided). However, when the body panel 14 (mainly made of sheet metal) and the glass 18 are compared, the flatness on the surface is often more easily secured by the glass 18, and thus at least a dowel that contacts the glass 18 is formed. preferable.

  In addition, in the above, as an example of the member mounting structure of the present invention, the glass 18 and the vehicle body panel 14 are cited as mounted members, and the example in which the wire harness 20 is applied to the structure to which these are mounted is shown. The member to be attached which is the target of the member attachment structure is not limited to the glass 18 or the vehicle body panel 14. That is, the present invention can be applied to a structure in which a filler is filled between a plurality of attached members, and the penetrating member penetrates so as to cross the filler. As the penetrating member, the electric wire 24 is taken up as described above, but it is not limited to this.
