DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing structure for a superposed member.

[0002]

2. Description of the Related Art As this kind of technique, as shown in FIG. 3 (see Japanese Utility Model Application Laid-Open No. 58-54958), for example, an inspection hole cover 2 which is a "first panel" is used as a sealing structure 1 of a superposed member. Of the floor panel 4 which is the “second panel” is overlapped with the edge 3 of the floor panel 4, and among the through holes 7 and 8 penetrating the overlapped portion, the outside of the floor panel 4 A plate nut 9 is welded to the through hole 8 on the surface 4a of the OR, and a bolt 10 screwed to the plate nut 9 is inserted from the indoor side IR surface 2a of the edge 3 of the inspection hole cover 2 and locked. The embossment 1 formed on the portion 6 of the inspection hole cover 2 separated from the edge 3 of the inspection hole cover 2 and on the edge 5 of the floor panel 4
The first seal member 14 is provided in a space 13 between the first seal member 14 and the second seal member 14. A bolt 10 projecting from the plate nut 9 when screwed is provided outside the plate nut 9.
A bolt cover 15 made of a synthetic resin material is arranged so as not to cause damage to other parts by the head. The plate nut 9 and the bolt 10 constitute a “fixing member”. Reference numeral 5a denotes a flange bent from the edge 5 of the floor panel 4 to the position where the first seal member 14 is provided. Reference numeral 19 denotes an inspection hole formed endlessly by the edge 5.

FIG. 4 shows another conventional example, in which a screw grommet 17 made of a synthetic resin material with a sealing rubber 16 interposed is fitted to the indoor side IR surface 4b of the floor panel 4 toward the outdoor side OR. Bolt cover 1 as in the conventional example
5 is unnecessary. A tap screw 18 screwed into the screw grommet 17 is inserted and locked from the indoor side IR surface 2a of the edge 3 of the inspection hole cover 2 with the inspection hole cover 2 interposed therebetween.
The reason why the first seal member 14 is interposed in the space 13 between the portion 6 separated from the edge 3 of the inspection hole cover 2 and the emboss 12 formed on the edge 5 of the floor panel 4 is as follows. This is the same as the conventional example. The screw grommet 17 and the tap screw 18 constitute a “fixing member”.

[0004]

However, in the former case of the prior art, the bolt cover 15 is required to prevent other parts from being damaged, the cost is high, and an assembling tool is required. . Further, in the latter case of the above-described conventional example, the number of parts requires the screw grommet 17 and the tap screw 18, and furthermore, after the screw grommet 17 is assembled, the tap screw 18 is screwed into the screw grommet 17. Because of the stage method, a large number of assembly steps are required. Therefore, an object of the present invention is to provide a sealing structure for a polymer member that is inexpensive and requires less assembly steps.

[0005]

According to the present invention, there is provided a sealing structure for a superposed member, wherein the edge of the second panel is superimposed on a portion separated from the edge of the first panel, and the penetrating portion penetrating the superposed portion is provided. The fixing member is locked in the hole, and the first member is located between the edge of the first panel and a portion separated from the edge of the second panel.
In a sealing structure of a superposed member having a sealing member interposed therebetween, the fixing member and a surface opposite to a surface directly superimposed on the second panel at a portion separated from an edge portion of the first panel, 2 the first seal member is the second seal member
It is characterized by being outside the seal member.

[0006]

[Operation] According to this structure, the sealing is completed by the second sealing member only by locking the fixing member in the through hole, so that the number of parts is reduced and the number of assembling steps is reduced.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. 1 and 2, a sealing structure 1 of a superposed member is shown.
Is formed by overlapping the edge 5 of the floor panel 4 as the “second panel” with a portion 6 separated from the edge 3 of the inspection hole cover 2 as the “first panel”, and penetrating through the overlapping portion. A clip 20 which is a “fixing member” in the holes 7 and 8
It is locked. The clip 20 is inserted from the indoor side IR of the through hole 7 of the inspection hole cover 2 and is locked to the surface 4a of the outdoor side OR of the through hole 8 of the floor panel 4. Each head 20a is in contact with the IR surface 2a, and each leg 20b is engaged with the outdoor OR surface 4a of the through hole 8 of the floor panel 4.

The head 20a of the clip 20
And a surface directly overlapping with the floor panel 4 at a portion 6 separated from the edge portion 3 of the inspection hole cover 2, that is, a surface 2 of the indoor side IR which is a surface opposite to the surface 2b of the outdoor OR.
and a ring-shaped seal rubber 21 as a “second seal member”.

A space 13 is formed between the edge 3 of the inspection hole cover 2 and a portion 11 separated from the edge 5 of the floor panel 4 by an emboss 12, and a space 13 is formed in the space 13. The configuration in which one sealing member 14 is interposed is the same as that of the conventional example. The first seal member 14 is a ring-shaped seal rubber 2 serving as a second seal member.
Outside of 1.

According to this embodiment, first, the edge 3 of the inspection hole cover 2 which is the "first panel"
The edge portion 5 of the floor panel 4 that is the “second panel” is overlapped with the portion 6 that is farther away, and the clip 20 that is the “fixing member” is locked in the through holes 7 and 8 that pass through the overlapped portion. At this time, a ring-shaped sealing rubber 21 serving as a “second sealing member” previously supported by the clip 20 is interposed on the indoor side IR surface 2 a of the portion 6 separated from the edge 3 of the inspection hole cover 2. Therefore, even if the fluid W such as rainwater passes through the through hole 8 of the floor panel 4 and the through hole 7 of the inspection hole cover 2 from the outdoor OR,
The seal rubber 21 serving as the “second seal member” prevents further intrusion. Further, even if the fluid W such as rainwater passes through the through hole 8 of the floor panel 4 and reaches the space 13 of the embossment 12, further intrusion is prevented by the first seal member 14.

The clip 20 supporting the seal rubber 21 serving as the "second seal member" in advance is attached to the "first panel".
The floor panel 4 which is the "second panel" is located at a position 6 separated from the edge 3 of the inspection hole cover 2 which is
Are overlapped, and the through holes 7 and 8 penetrate the overlapped portion.
Since the above-mentioned effects can be achieved only by fitting and locking to
It is inexpensive and can be mounted with one touch.

In the above-described embodiment, the relationship between the inspection hole cover 2 and the floor panel 4 of the automobile has been described. However, the present invention is not limited to this. All that is supposed to invade is included.

[0013]

As described above, according to the present invention, as the sealing structure of the overlapping member, the edge of the second panel is superimposed on a portion separated from the edge of the first panel, and the overlapping portion is formed. A seal for a superposed member, wherein a fixing member is locked in a penetrated through hole and a first seal member is interposed between an edge of the first panel and a portion separated from an edge of the second panel. In the structure, a second seal member is interposed between the fixing member and a surface opposite to a surface directly overlapping with the second panel at a portion separated from an edge portion of the first panel, and the first seal member is provided. Since it is characterized by being outside the second seal member, the seal is completed by the second seal member only by locking the fixing member in the through hole, so that the number of parts is reduced and the number of assembling steps is reduced. Has a profitable effect.
