As shown in the figure, the sealing material has a long shape and the trim portion 26
And a seal portion 28. The trim portion 26 and the seal portion 28 are formed of a synthetic resin such as a vinyl chloride resin (PVC). The trim portion 26 has a substantially U-shaped cross section, and the core material 30 is embedded therein. The core member 30 is made of metal and has a long cross-girder shape along the sealing material. The sealing material is formed (extruded) in a state where the flat core material 30 is embedded in the flat trim portion 26, and then the core material 30 is bent into a substantially U-shaped cross section, thereby forming the above-described sealing material. The shape is as follows. As shown in FIG. 2A, the sealing material includes a sealing material main body (a trim portion 2).
In some cases, the cloth material 40 made of synthetic fiber is adhered to the surface of 6) with an adhesive 45.

Reference numeral 122 denotes a part of the cross-sectional area of the synthetic resin portions 120a and 120b (because there is a gap S21). For this reason,
The cross-sectional area of the portion where the two sealing materials 110a and 110b are bonded (the welded portion 12 of the synthetic resin portions 120a and 120b)

低下するとともに、外観も低下する。At the time of the above-mentioned welding, the air existing in the hollow portion S1 is heated to a high temperature and expands to expand the synthetic resin portion 120.
In some cases, the air may escape from the outside through the welded portion 122 of each of the synthetic resin portions 120a and 120b. For this reason, the adhesive strength between the synthetic resin portions 120a and 120b (that is, the adhesive strength between the sealing materials 110a and 110b) is reduced by that amount, and the appearance is also reduced.

When the vicinity of the end of 40b is curved, the adhesive 145a, 1
The synthetic resin portion 110 is formed due to, for example, cracking of the 45b layer.
In some cases, the adhesive strength of the cloth materials 140a, 140b to the a, 110b is reduced, and the ends of the cloth materials 140a, 140b may come off from the synthetic resin parts 110a, 110b (the sealing material main body).

着させるものである。In order to solve the above-mentioned problems, the invention according to claim 1 is a method for bonding a sealing material for a vehicle, which bonds end portions of a sealing material for a vehicle including a core material. In this state, each end of the sealing material is welded to each other while the adhesive is filled in each cavity formed by removing the core material near each end of the both sealing materials. is there.

増加して、両シール材の接着強度が向上する。In the bonding method according to the present invention, the ends of the two seals are welded together, so that the ends of the two seals are also bonded by the adhesive. That is, the cores of the two seals may be bonded to each other with an adhesive, or the gap formed between the two seals when the ends of the two seals are welded may also be bonded to the adhesive. . For this reason, the cross-sectional area of the part where both sealing materials are bonded increases correspondingly, and the bonding strength of both sealing materials improves.

For this reason, the cross-sectional area of the part where both sealing materials are bonded is maximized, and the bonding strength of both sealing materials is improved. In addition, since air remaining between the two seal members does not escape to the outside due to thermal expansion at the time of welding, no air hole is generated. Therefore, the air holes do not reduce the adhesive strength of the synthetic resin portion, and the appearance does not deteriorate.

(Synthetic resin parts 20a, 20b) are welded. Therefore, no air remains between the two sealing members 10a, 10b, and the air remaining between the two sealing members 10a, 10b is thermally expanded at the time of welding, so that the synthetic resin portions 20a, 20b are formed.
Since the resin b does not escape to the outside through the welded portions 21 and 22, no air holes are formed in the synthetic resin portions 20a and 20b. Therefore, the synthetic resin portion 20a,
The adhesive strength of 20b does not decrease, and the appearance does not decrease.
