Furthermore, the vehicle inner side surface of the trim is fixed to the outer panel with an adhesive tape or the like (refer to FIG. 3 and paragraph 0023 of Patent Document 1, etc.). In addition to this mounting method, as shown in FIG. 7 of Patent Document 2, for example, a trim is also used to fasten the trim to the door panel on the side of the window glass (the side opposite to the boundary portion) by fasteners for fixing Methods. In this case, after the fastening portion extending in the vehicle interior direction is provided in the window glass side portion of the garnish, the fastening portion is fastened to the door panel with the fastener. When this method is employed, the edge of the garnish on the boundary portion side is usually hooked to the edge of the door panel, and then the fastening portion is attached to the door panel and fastened with fasteners.

In the mounting structure of the boundary seal of Patent Document 1 shown in FIG. 9 , although the boundary seal 600 can be easily assembled to the trim 500 as described above, there may be problems in its manufacture and the like. Hereinafter, this will be described in detail.

First, in the trim 500, it is necessary to provide projections 502 to the groove-shaped mounting grooves (openings) 501 opening in the front-rear direction of the vehicle to prevent the boundary seal 600 from falling off. However, due to the design, the front view of the car, especially in the upper part of the belt line, is almost not completely straight, and in fact, almost always leans toward the inside (inside of the vehicle) as it goes up. and gently curved lines. Therefore, in the sectional structure of the garnish of Patent Document 1, the die cutting at the time of molding the garnish 500 is not considered on the premise that the garnish 500 has a gentle curve, and this structure is difficult to realize. That is, the mold provided at the position of the opening 501 on the trim 500 cannot be disengaged in both the vehicle front-rear direction and the vehicle vertical direction, for example, it needs to be located at the side wall position S on the outside of the opening 501 or the inside of the vehicle. A hole for demolding is provided. However, the trim 500 is a member exposed to the outside, and it is not preferable if the hole is provided at the side wall position S on the outside of the vehicle or the inside of the vehicle, etc., since the appearance will be deteriorated.

Furthermore, although the tip of the fitting portion 601 of the boundary seal 600 of Patent Document 1 is in the shape of an arrow, when the boundary seal 600 is made of a hard material, it is necessary to make the column portion of the fitting portion 601 to a certain extent. It is thinned so as to be inserted into the opening portion 501 of the trim 500 . However, in this way, the boundary seal tends to loosen, which is not preferable. Alternatively, the fitting portion 601 may be formed in a hollow shape so that it can be easily bent so as to be inserted into the opening portion 501. However, in order to manufacture the hollow portion, the cross-sectional shape of the boundary seal 600 needs to be enlarged, which increases the cost. Furthermore, in order to manufacture a hollow part, it is necessary to make a pillar part thick to some extent, and the opening width of the opening part of a garnish also needs to be enlarged accordingly, which is not preferable. In addition, the arrow portion at the tip of the fitting portion 601 needs to be thin, so that the shape stability is insufficient when the cross-sectional shape of the boundary seal 600 is extruded, and it is not suitable for mass production.

However, the material of the boundary seal 40 is not particularly limited as long as it is a rubber-based elastic material, and as the rubber material, for example, EPDM (ethylene-propylene-diene rubber) can be used. In addition, as the resin material, for example, TPE (thermoplastic elastomer) can be used. Furthermore, although the case where the entire cross-sectional shape of the boundary seal 40 is a non-foamed material is exemplified, a foamed material may be used for each part of the cross-sectional shape of the boundary seal 40 as needed.

Next, an attachment structure for attaching the boundary seal 40 to the trim 30a according to the present embodiment will be described. As shown in FIG. 6, the boundary seal 40 is assembled to the trim 30a by inserting the mounting feet 43 into the mounting grooves 34 of the trim 30a. As described above, the mounting groove 34 has two different shapes of the first mounting groove 35 and the second mounting groove 36 , and the engagement forms with the mounting legs 43 are different from each other.

As shown in FIG. 6( a ), in a state where the mounting legs 43 of the boundary seal 40 are inserted into the first mounting grooves 35 , the vehicle outer side locking protrusions 35 a and the vehicle inner side locking protrusions 35 b of the first mounting groove 35 are respectively The vehicle outer protrusions 43 a and the vehicle inner protrusions 43 b of the mounting leg 43 are caught, and the movement of the mounting leg 43 in the direction of coming out of the mounting groove 34 is restricted. In addition, since the positions of the vehicle outer protrusion 43a and the vehicle inner protrusion 43b and the vehicle outer locking protrusion 35a and the vehicle inner locking protrusion 35b of the mounting leg 43 are respectively shifted in the vehicle front-rear direction, the mounting leg 43 can be inserted into the vehicle. When the mounting groove 34 is in the mounting groove 34, the timing of the locking projections 35a on the outside of the vehicle and the locking projections 35b on the inside of the vehicle are shifted, so that it can be easily inserted. Furthermore, since the mounting leg portion 43 has the abutment protrusion 44 described above, and the contact protrusion 44 is in contact with the front side (the seal lip 42 side) of the vehicle outer side wall 34 a of the mounting groove 34 , the mounting leg portion 43 is removed from the vehicle outer side. In addition to the engagement of the protrusions 43a and the vehicle inner side protrusions 43b with the vehicle outer side locking protrusions 35a and the vehicle inner side locking protrusions 35b of the first mounting groove 35, the front side ( The contact of the seal lip 42 side) prevents the mounting leg 43 from loosening in the mounting groove 34 . Thereby, the mounting stability can be improved.

Among them, the stability of the three-point support after installation, such as preventing the mounting leg 43 from loosening in the mounting groove 34 by the above-mentioned three kinds of protrusions, and the insertion operability at the moment when the vehicle inner protrusion 43b passes the vehicle outer locking protrusion 35b are two aspects. From a viewpoint, it is preferable that the contact protrusion 44 is provided on the front side (the seal lip 42 side) of the vehicle inner side protrusion 43b. In addition, since the cover lip 45 of the boundary seal 40 covers the interior side of the vehicle interior side wall 34b and is mounted, it also covers the through hole 35c provided in the vehicle interior side wall 34b of the first mounting groove 35. Therefore, the through-hole 35c can be prevented from being seen from the inside of the vehicle, thereby improving the appearance. Of these, it is preferable that the covering lip 42 has a length set so as to cover the rear end of the through hole 35c when the boundary seal 40 is mounted in the mounting groove 34 of the trim 30a.

As shown in FIG. 6( b ), since the second mounting groove 36 is not provided with the vehicle outer side locking protrusion 35a and the vehicle inner side locking protrusion 35b as in the first mounting groove 35, the vehicle outer side protrusion 43a of the mounting leg 43 and the vehicle outer side protrusion 35b are not provided. None of the inner protrusions 43b is caught. However, in the first mounting grooves 35 provided alternately (intermittently) with the second mounting grooves 36 , the vehicle outer protrusions 43 a and the vehicle inner protrusions 43 b of the mounting legs 43 are blocked by the vehicle outer locking protrusions 35 a and the vehicle inner locking protrusions, respectively. 35b is stuck, so that the movement of the boundary seal 40 in the direction of disengagement from the mounting groove 34 is restricted. In addition, the vehicle outer side protrusion 43a and the vehicle inner side protrusion 43b of the mounting leg 43 may be in contact with the vehicle outer side wall 34a and the vehicle inner side wall 34b, respectively, in the second mounting groove 36 to further improve the prevention of the mounting leg 43. The effect of loosening in the mounting slot 34. In addition, as long as the boundary seal 40 is not easily detached from the installation groove 3 or the looseness of the boundary seal 40 in the installation groove 34 is prevented from increasing, the outside protrusions 43a and the inside protrusions 43b may be connected to the installation grooves. A small gap is set between the inner walls of 34 to improve insertion operability.

In this embodiment, the installation structure of the boundary seal 40 provided on the trim 30a on the front end side of the rear door 1 has been described, but the present invention can of course also be applied to the trims 30b, 30c, Demarcation seal 40 mounting structure at 30d etc. Of course, for example, in the trim 30b provided on the rear end side of the rear door 1, the front-rear direction of the boundary seal mounting structure is opposite to that described in the above-mentioned embodiment.

As described above, according to the installation structure of the boundary seal 40 of the present invention, the boundary seal 40 can be directly installed on the installation groove 34 provided at the decorative part 30a, so there is no need to consider the decorative part 30a, the window frame and the boundary seal The assembly sequence of the part 40 on the door panel can be improved, so that the installation workability of the boundary seal 40 can be improved. In addition, in the installation structure of the boundary seal 40 according to the present invention, the vehicle outer protrusion 43a and the vehicle inner protrusion 43b of the mounting leg 43 of the boundary seal 40 and the first installation groove 35 of the decorative piece 30a are The positions of the vehicle outer side locking projections 35a and the vehicle inner side locking projections 35b are respectively shifted in the vehicle front-rear direction. Therefore, when the mounting leg portion 43 is inserted into the first mounting groove 35, the timing at which the mounting leg portion 43 passes through the vehicle outer side locking protrusion 35a and the vehicle inner side locking protrusion 35b can be shifted, thereby enabling easy insertion. In addition, the size of the mounting legs 43 can be set so as to fit into the mounting grooves 34, and since only the protruding portion is added, it can be easily manufactured. On the other hand, since the installation groove 34 of the decorative piece 30a includes the first installation groove 35 having the above-mentioned locking protrusion and the second installation groove 36 without the above-mentioned locking protrusion, it is different from the above-mentioned conventional installation groove, especially The mold for forming the first mounting groove 35 can be easily demolded. Therefore, the installation structure of the boundary seal of the present invention can be easily manufactured.
