2. Description of the Related Art There has been proposed a mounting structure in which the mounting base of a weather strip having a mounting base and a seal portion is opened and closed with respect to a body side opening of an automobile, for example, is adhered to a peripheral edge of a door with a double-sided tape. JP-A 1-229718, JP-A 1-249547).

[0003]

Since a linear portion and a curved portion are mixed on the periphery of the door, one of the two adhesive surfaces of the double-sided tape is adhered to the weather strip, and in this state, both surfaces are adhered. If the other adhesive surface of the tape is to be manually adhered to the periphery of the door, the position of the weather strip tends to shift. Further, when the worker touches the adhesive surface of the double-sided tape, the adhesive force may be reduced.

[0004] The above-mentioned problem can be solved by mechanically bonding the other adhesive surface of the double-sided tape to the peripheral edge. However, dedicated equipment is required for that purpose, so that a large capital investment is required. Must.

Accordingly, it is an object of the present invention to bond a double-sided tape manually, and
It is an object of the present invention to provide a weather strip mounting structure that does not cause displacement and does not substantially touch an adhesive surface with an operator's hand.

[0006]

According to the present invention, there is provided a structure in which the mounting base of a weather strip having a mounting base and a seal is mounted on a peripheral edge of a means for opening and closing an opening of a body of an automobile by a double-sided tape. is there. The double-sided tape is attached to the adhesive surface to be adhered to the peripheral edge of the opening / closing means in a releasable manner, and a pair of release papers disposed on both sides of a separation portion extending in the longitudinal direction are formed on a single double-sided tape. The tape is formed to have. The weatherstrip has a plurality of clips attached to a portion of the attachment base that is longitudinally spaced and having a through portion that passes through a separation portion of the double-sided tape. The penetrating portion is formed to be wider than the width of the separating portion.

[0007]

A plurality of clips are inserted into predetermined holes in the periphery of the opening / closing means without peeling off a pair of release papers on the bonding surface to be adhered to the periphery of the opening / closing means. Temporarily fix. In this way,
After arranging the weather strip on the periphery of the opening / closing means, each of the pair of release papers is peeled off from the adhesive surface, the mounting base of the weather strip is pressed against the periphery of the opening / closing means, and the adhesive surface of the double-sided tape is adhered.

[0008] Since the weather strip is temporarily fixed by a plurality of clips prior to the actual bonding, the weather strip can be easily and accurately mounted in a proper position. In addition, since no displacement occurs, work such as correction is not required, and workability can be significantly improved.

[0009] A pair of release papers may be inserted by inserting a plurality of clips into predetermined holes on the periphery of the opening / closing means, and after peeling the weather strips, peeling them off. There is virtually no sex. Therefore, there is no possibility of lowering the adhesive strength.

Since a pair of release papers are separated by a separation portion extending in the longitudinal direction and a plurality of clips penetrate the separation portion, each of the pair of release papers is separated from the plurality of clips. Can be peeled off from both sides individually. Since the width of each release paper can be made approximately half the width of the adhesive surface of the double-sided tape, the release paper can be easily peeled from a narrow place. In addition, since the penetrating part of the clip is thicker than the width of the separating part, the width of the separating part can be made as small as possible independently of the clip.
