Description of the Related Art Here, a corner portion C1 located at a connection portion between a door sash 3 and a vertical frame 5 for a mirror bracket in a door glass run 1 of a front door D1 will be described as an example of a complementary seal structure for a weather strip. However, it is not limited to this (see FIG. 1).

である。As shown in FIG. 2, the cross section of the glass run 1 is a pair of bent seal lips 7 and 7, which extend inwardly toward the bottom, and complements both sides of the bottom sash for attaching and holding to the door sash 3. The seal fins 9, 9 are formed. The bent seal lips 7 and 7 are in contact with both surfaces of the glass G, and the complementary seal fins 9 and 9 are the door sashes 3.
It comes into contact with the bottom of the groove and has a sealing effect.

でなく、補完シール性に劣る。In this case, extensions 9A and 9B of the complementary seal fin 9 are also formed in the corner C1. In this case, it is difficult to form the extension 9A into a fin shape due to the molding technique, and normally, the extension 9A has a rib shape that is hard to follow and deform. Therefore, the followability to the groove bottom portion of the door sash 3 is not sufficient, Inferior in complementary sealability.

Therefore, in order to further enhance the complementary sealing property, as shown in the figure, the first elastic sealing material 13a is adhered over substantially the entire length of the corner portion C1 and the second elastic sealing material shorter than the first elastic sealing material 13a is attached. Thirteen
It is proposed that b is attached and the elastic sealing material 13 is formed in two layers at the center of the corner (Actual Kaihei 4-29420).

Here, the sealant refers to a material that can be fluidized or fluidized before application and can be applied to an arbitrary length, width, and thickness from an application gun. A material that acts to seal a gap. Sealant,
The reason why the elasticity is limited to the foaming elasticity is that if the elasticity is not the foaming elasticity, it is difficult to obtain the flexibility after the curing for the sheet metal of the vehicle body and the like in the sealant after curing, and it is difficult to perform the action of the complementary seal. Although it is not particularly limited as long as it has the flexibility of providing a complementary seal, the expansion ratio is usually 1 to 4 times, and the compression hardness is 0.2 kg / cm 2 or less. Further, the presence or absence of surface tackiness after curing does not matter.
