## Background
BACKGROUND OF THE INVENTION
This invention relates to a mounting structure of a weather strip which is mounted on a door panel or a body panel of an automobile, and which, besides a sealing function, comprises a fin portion in a die molded part thereof in order to cover holes, e.g., access holes, formed in the panel.
There have been provided, for example, access holes in an interior side of a door panel of an automobile for a use of adjusting such as a door glass elevation mechanism. And, there has been a weather strip which is mounted on the door panel, and which comprises a fin portion in a die molded part thereof for an application of covering the holes.
The fin portion of the weather strip is mounted on the door panel, and the mounting operation in most cases is carried out with clips or a double-sided adhesive tape. A shape of the clip is introduced, for example, in the Japanese Unexamined Patent Publication No. 10-220436
However, the conventional weather strip whose fin portion is mounted on the panel with the clips has a problem that an outlook thereof is deteriorated since head portions of the clips are exposed.
Further, the conventional weather strip whose fin portion is mounted with the double-sided adhesive tape has also a problem that the weather strip is inclined to be placed inaccurately since the double-sided adhesive tape is not provided with a positioning function like the clip.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 5, there will be described a preferred embodiment of a mounting structure of a weather strip according to the invention.
FIG. 1 is a side view showing a door panel 1A of an automobile comprising a mounting structure of a weather strip according to the preferred embodiment of the invention. FIG. 2 is a back view showing the door panel 1A viewed from the direction indicated with the arrow “X” in FIG. 1. FIG. 3 is a back view showing a structure in which a weather strip 2 is mounted on the door panel 1A. FIG. 4 is a sectional view along line I—I in FIG. 3. FIG. 5 is a back view showing a weather strip in combination with an engagement member.
In this mounting structure of a weather strip, a weather strip 2 is mounted on a rear end portion of a door panel 1A of an automobile, wherein a fin portion 4 formed in a die molded part of the weather strip 2 is arranged to cover a mounting hole 1a formed in the door panel 1A.
The weather strip 2 comprises extrusion molded parts 5 integrally formed at both ends of the die molded part 3, wherein a hollow portion 2a, which is continuously formed through the die molded part 3 and the extrusion molded part 5, is making a resilient contact with a body panel 1B to seal a gap between the door panel 1A and the body panel 1B. The weather strip 2, except the fin portion 4 thereof, is secured to the body panel 1B with clips or double-sided adhesive tapes.
An insert plate 6 made of hard resin material is embedded in the fin portion 4 of the die molded part 3, which is provided with a locking projection 7 and is protrudely formed from the fin portion 4 and is exposed out of the fin portion 4. An engagement member 8 is attached to the locking projection 7 capable of disconnecting. The engagement member 8 is inserted into a mounting hole 1a formed in a door panel 1A, which is also used as an access hole for regulating an adjusting mechanism provided inside a door, thereby mounting the weather strip 2 on the door panel 1A. In this embodiment, the area in the surface of the insert plate 6 surrounding the locking projection 7, where the engagement member 8 makes a contact, is also exposed, like the locking projection 7. The invention includes such a technical scope that the engagement member 8 can be inserted into any existing hole 1b instead of the mounting hole 1a. Further, the insert plate 6 may be sandwiched inside the fin portion 4 instead of being embedded in the fin portion 4 in a manner not to be viewed from outside after the weather strip 2 is mounted on the door panel 1A of an automobile.
As illustrated in FIG. 6, according to this preferred embodiment of the invention, the locking projection 7 is provided with a periphery groove 7a around the outer circumference surface of the column-like body forming the locking projection 7. Further, as illustrated in FIGS. 6 to 9, the engagement member 8 is provided with a plural number of inner projections 8b in the inner circumference surface of the ring-like body forming the engagement member 8, to carry out engagements with the periphery groove 7a of the locking projection 7. The engagement member 8 is also provided with a plural number of locking parts 8a in the outer circumference surface of the ring-like body forming the engagement member 8 for engagements with the mounting hole 1a of the door panel 1A, capable of disconnecting. Each locking part 8a elastically deforms in a corresponding open space 8d having the upper end portion thereof as a base of the deformation. There are provided supporting projections 8c between the inner projections 8b of the engagement member 8 in order to stabilize a mounting posture of the engagement member 8 in relative to the locking projection 7.
In this preferred embodiment of the invention, a mounting operation of the weather strip 2 can be carried out in the following manner.
First, the engagement member 8 of the insert plate 6, which projects out of the fin portion 4 of the weather strip 2, is attached to the locking projection 7. This attachment operation is performed by engaging the inner projections 8b provided in the inner periphery surface of the engagement member 8 with the periphery groove 7a provided to the locking projection 7.
Secondly, the engagement member 8 attached to the fin portion 4 of the weather strip 2 is inserted into the mounting hole 1a formed in the door panel 1A, engaging the plural number of locking parts 8a provided in the outer peripheral surface of the engagement member 8 with the mounting hole 1a which is used as an access hole as well. By doing so, the fin portion 4 of the weather strip 2 is accurately secured to a right position, and the mounting hole 1a can be assuredly covered by the fin portion 4.
Further, the engagement member 8 is able to take a position between the fin portion 4 and the door panel 1A, so that the engagement member 8 is not viewed from an outside, and that an outlook thereof is good.
In this preferred embodiment of the invention, although the weather strip 2 is mounted on the door panel 1A, the invention is not limited to such structure and the weather strip 2 can be mounted on a body panel 1B to cover any hole, e.g., a mounting hole.
Further, according to the invention, the fin portion 4 and the locking projection 7 can be made of a hard rubber material or hard resin material instead of providing the insert plate 6. By providing such structure, it is unneeded to produce the insert plate 6, and it is also unneeded to mount the insert plate 6 in the die molded part 3 of the weather strip 2. Therefore, the production cost as well as the production process can be reduced, thereby improving the productivity.
