The clip 7 is provided with claws 7c, 7d, etc. at appropriate locations, and furthermore, both left and right ends 7 of the clip 7 shown in the drawing are
Engagement pieces 3a and 8b of the molding body 8 are engaged with e and 7f. Reference numeral 30 denotes a door sash, which is in contact with the outer side end of the quarter panel 4 with a seal lip 31 interposed therebetween when the door is closed.

The above-mentioned clips 7 are provided to attach the molding body 8 to the fastener 5, and are attached in an appropriate number while maintaining an appropriate interval in the longitudinal direction of the long fastener 5. The clip 7 supports the molding body 8 with respect to the fastener 5 in such a manner that it is prevented from coming off. 10 is a rain gutter portion formed between the loop molding 2 and the loop panel 3.

Problems to be Solved by the Invention However, in such a conventional mounting structure for the loop molding 2, since the fastener 5 and the clip 7 are interposed between the loop panel 3 and the molding body 8, the number of parts is reduced. There were problems in that the number of parts increased, the work process at the time of installation became complicated, and the cost required for four installations increased. Further, if the adhesive 6 is not sufficiently bonded, the hard piece 5a of the fastener 5 tends to peel off from the loop panel 3, resulting in a disadvantage in that the appearance deteriorates.

Furthermore, since the clips 7 are attached to the long fastener 5 while maintaining appropriate spacing in the longitudinal direction, air or moisture easily enters the inside of the molding body 8 from the portions where the clips are not provided, which makes it difficult to run. There are problems in that wind noise may be generated inside the molding body, and if the molding body 8 is made of metal material, rust may occur.

Therefore, the present invention solves the problems that conventional loop moldings for automobiles have, simplifies the work process during assembly by minimizing the number of parts, and makes it possible to remove the loop molding. The object of the present invention is to provide an automatic Ogawa loop molding which does not generate air leakage and can prevent the infiltration of air and moisture.

Means for Solving the Problems In order to achieve the above object, the present invention provides a method of erecting the ends of the loop panels overlapped and welded to the quarter panels on both sides of the two-sided vehicle. In a configuration in which a loop molding is attached using a flange portion provided with a flange portion, the loop molding described in “2” consists of a molding body, a pillar protruding downward from the molding body, and a pillar of the pillar. A lip extends from the lower end to the quarter panel side and contacts the quarter panel at I, ql, and a lip extends from the lower end of the support to the loop panel side and the tip of the flange portion is locked at the tip D: 11 part. A loop for an automobile comprising a support piece having a locking part formed therein, and a leg part that projects downward from the loop side end of the molding body and is bonded to one end of the surface of the loop panel. This is the structure of the mall.

According to this structure, when assembled, the tip of the flange portion of the loop panel is locked in the engagement bay formed on the upper side of the support piece, and while this state is maintained, the tip portion of the flange portion of the loop panel is inserted downwardly into the leg portion. The installation work of the loop molding is completed by adhering the located fixing piece to one end of the surface of the loop panel.

In the loop molding assembled in this way, since the lip is in elastic contact with the surface of the quarter panel, the fixed piece of the loop molding is pressed toward the loop panel side by the elastic force of the lip, and the fixed piece and the loop This provides the effect of increasing adhesion between panels. Further, by increasing the adhesion between the lip and the fixing piece and the loop panel, the airtightness inside and outside the loop molding is improved.

Embodiment Hereinafter, an embodiment of a loop molding for an automobile according to the present invention will be described in detail with reference to the drawings, with the same reference numerals attached to the same components as in the conventional structure.

In the configuration shown in FIG. 1, 3 is a loop panel, 4 is a quarter panel, and both panels 3 and 4 are welded at an overlapping portion 20. The loop panel 3 has a flange portion 3a extending upward from one end portion of the loop panel 3 on the outside of the vehicle.
