Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for an air dam such as a front air dam and a side air dam of an automobile.

[0002]

[Prior Art]

 An example of a conventional front air dam mounting structure is shown in FIGS. 4 and 5. As shown in FIG. 4, the front air dam 1 is attached to a lower portion of the front bumper face 2. A vertical sectional view taken along the line AA of FIG. 4 is shown in FIG. The tongue piece 3 that is integrally formed with the upper part of the air dam 1 and bends downward inward is closely contacted with the lower outer surface of the bumper face 1, and the bolt 4 with a washer is inserted from the gap between the air dam 1 and the tongue piece 3. The air dam 1 was fixed to the bumper face 2 by inserting the rod portion 4a through the tongue piece 3, the bumper face 2 and the seat plate 5 and screwing and fastening a nut 7 at the tip thereof.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional structure, when the gap between the air dam 1 and the tongue piece 3 becomes small, the washer bolt 4 cannot be inserted, so that the forms of the air dam 1 and the bumper face 2 are limited. It was If the washer bolt 4 is installed away from the upper end of the air dam 1 in order to deal with this, there is a problem that the inner surface of the upper end of the air dam 1 does not come into close contact with the outer surface of the bumper face 1 and the appearance is impaired.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed to solve the above-mentioned problems, and its gist is to provide a mounting member with a protrusion that is integrally formed with an air dam by injection molding of synthetic resin and projects inward from the upper portion of the inner surface of the air dam. The bolt head is housed in the hole formed in the projection, and the head of the bolt is housed in the cavity formed in the projection from the inlet opening on the side surface of the projection. By penetrating through the tip end face and projecting inward, through a bolt hole formed integrally with the above-mentioned mounting member or formed in the seat installed behind it and screwing and fastening a nut at its tip end. An air dam mounting structure is characterized in that the air dam is fixed to the mounting member by closely contacting the inner surface of the upper part with the outer surface of the mounting member.

[0005]

[Action]

 Since the present invention has the above-mentioned configuration, the protrusion integrally formed with the air dam is inserted into the hole formed in the mounting member, the head of the bolt is housed in the cavity from the inlet, and the rod portion is housed. The air dam is fixed to the mounting member by penetrating the tip end surface of the protrusion and projecting inward and penetrating the bolt hole formed in the seat and screwing and fastening a nut at the tip.

[0006]

【Example】

 One embodiment of the present invention is shown in FIG. At the upper part of the inner surface of the air dam 1, a rectangular parallelepiped projection 10 is formed integrally with the air dam 1 when the air dam 1 is injection molded with a synthetic resin. A cavity 11 having a rectangular cross section is formed inside the protrusion 10, and an inlet 12 communicating with the cavity 11 is formed on at least one side surface of the protrusion 10. A slit 13 is cut from the inlet 12 on the tip surface of the protrusion 10. The bumper face 2 is provided with a hole 14 into which the projection 10 is loosely fitted, and a pair of ribs 15 projecting inward are provided at the upper and lower edges of the hole 14 so as to project.

Then, the rod portion 16a of the bolt 16 is fitted into the slit 13 and the head portion 16b is inserted into the cavity 11 through the inlet 12 so that the rod portion 16a penetrates the tip surface of the protrusion 10. And project it inward. In this state, the projection 10 is inserted into the hole 14, and then the sheet metal seat 7 is bridged to the tips of the pair of ribs 15, and the rod 16a of the bolt 16 is drilled in the center of the seat 17. It is inserted into the hole 18 and penetrated. The air dam 1 is fixed to the bumper face 2 by screwing and fastening the nut 19 at the tip of the rod portion 16a of the bolt 16, and the inner surface of the upper part of the air dam 1 comes into close contact with the outer surface of the bumper face 2.

FIG. 2 shows a second embodiment of the present invention. In the second embodiment, a seat 20 having a U-shaped cross section is installed behind the air dam 1, and the tips of a pair of legs 20a extending outward from the upper and lower ends of the seat 20 contact the inner surface of the air dam 1. It is touched. The rod portion 16a of the bolt 16 penetrates a bolt hole formed in the seat 20, and a nut 19 is screwed and fastened to the tip of the bolt hole. The other structure is the same as that of the first embodiment shown in FIG. 1, and corresponding members are designated by the same reference numerals.

FIG. 3 shows a third embodiment of the present invention. The third embodiment is different from the second embodiment in that the seat 21 is integrally molded with the air dam 1, but the other configurations are the same, and corresponding members are designated by the same reference numerals. ing.

[Effect of the device]

 In the present invention, the protrusion protruding inward from the upper part of the inner surface of the air dam is inserted into the hole formed in the mounting member, and the head of the bolt is housed in the cavity formed in the protrusion. Since the rod part of the rod penetrates the tip surface of the above-mentioned protrusion and the bolt hole drilled in the seat and the nut is screwed and fastened to the tip, the bolt is inserted from the gap between the air dam and the tongue piece as in the past. You don't have to. Therefore, there are no restrictions on the shapes of the air dam and the mounting member, and the inner surface of the upper part of the air dam can be closely attached to the outer surface of the mounting member, and the mounting work becomes easy.
