First, the general shape of the belt line of the door outer panel 6 of the present invention, that is, the cross-sectional shape of the door outer panel 6 other than the portion where the center pillar 2 and the door outer panel 6 are joined will be described with reference to FIG.

  The outer weather strip 10 is formed of a seal portion 20 that seals between the door glass 5 and the door outer panel 6, and a molding portion 30 that covers and decorates the upper edge of the door outer panel 6. In the present embodiment, the seal portion 20 and the molding portion 30 are formed separately, and then fixed integrally with an adhesive or the like. However, when the sealing portion 20 is molded, a member constituting the molding portion 30 is formed as a molding die. And can be molded integrally.

The seal portion 20 is formed of a head portion 21, a main body portion 22, a first seal lip 26 and a second seal lip 27.
The cross-sectional shape of the head 21 is an inclined surface whose upper surface is lowered in the vehicle outer direction, and the cross-sectional shape is formed in a substantially triangular shape. The tip on the inside of the vehicle is formed in a lip shape, and the lower surface on the outside of the vehicle is formed in a flat shape.

A main body 22 extends downward from the head 21. The main body 22 is formed in a substantially plate shape. An insert 23 made of metal or hard synthetic resin is embedded in the main body 22. For this reason, the rigidity of the main-body part 22 increases and it becomes difficult to deform | transform. The main body portion 22 is fixed to the flange portion 7 at the upper end of the door outer panel 6 with screws or clips. Since the insert 23 is embedded in the main body 22, the main body 22 is securely fixed when the main body 22 is attached to the flange 7 at the upper end of the door outer panel 6, and the first seal lip 26 and the second seal are secured.
