[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for attaching a second member having a second mounting hole to a first member having a first mounting hole. It relates to a group clip clip consisting of. In particular, the present invention relates to a combined clip suitable for attaching a rubber member (second member) such as a weather strip to a vehicle body sheet metal (first member) in a portion where sealing performance is required.

Here, a solid rubber part (a kind of weather strip) will be described as an example, but the present invention is not limited to this.

[0003]

2. Description of the Related Art Conventionally, a solid rubber part (second member) 1 of this type is attached to a metal plate (first member) 3 of a vehicle body by a clip 5 as shown in FIG. The clip 5 is usually made of a synthetic resin including an umbrella-shaped head portion 11, a neck portion 13 and an elastic bulging leg portion 15.

That is, in a state where the second mounting hole 9 formed in the solid rubber component 1 is overlapped with the first mounting hole 7 formed in the vehicle body sheet metal 3, the elastic bulging leg portion 15 of the clip 5 is placed in the first mounting hole 7. One is pushed into the mounting hole 7 and inserted. Then, the elastic bulging leg portion 15 bulges after being inserted while reducing the diameter of the first mounting hole 7, and locks on the side surface opposite to the insertion side of the first mounting hole 7, that is, on the rear surface side of the vehicle body sheet metal 3. At the same time, the umbrella-shaped head 11 presses the insertion side surface of the second mounting hole 9 of the solid rubber part 1, that is, the front side surface of the solid rubber part 1.

Recently, it has been necessary to mount a solid rubber part on a sheet metal part of a vehicle body, which is required to have a sealing property, due to a specification change. In this case, it is conceivable to interpose first and second seal rings made of sponge rubber on the periphery of the first mounting hole on the front side of the body sheet metal and on the periphery of the second mounting hole on the front side of the solid rubber component, respectively (JP-A-58-58). 200
No. 809, etc.).

[0006]

However, it has been found that with this structure, sufficient sealing performance cannot be obtained (particularly between the body sheet metal and the rubber part). The reason is,
At the portion on the back surface of the umbrella-shaped head, the pressing force of the peripheral portion of the umbrella-shaped directly acts on the second seal ring to obtain good sealability, but between the body sheet metal and the rubber part, the second seal ring is provided. It is presumed that this is because the pressing force disperses and acts in a planar manner.

Further, when attaching the clip to the second member, the first seal ring can be assembled to the clip only after attaching the clip to the second member, and the first seal ring of the second member The workability of attaching to the member was not always good.

In view of the above, it is an object of the present invention to provide a combined clip which has a good sealability and a good workability of attaching the second member to the first member by the clip.

[0009]
