The seal between the door glass 5 and the door 1 is made by a glass run (not shown) attached to the channel 3 on the inner periphery of the door frame 2.

  Conventionally, as shown in FIG. 8, the door weather strip 110 attached to the outer periphery of the door frame 2 is composed of a mounting base portion 111, a hollow seal portion 114 and a seal lip portion 116 integrally formed on the upper surface thereof. The The mounting base 111 is fixed to the door frame 2 by being fitted into a U-shaped retainer portion 155 attached to the outer periphery of the door frame 2. When the door is closed, the seal lip 116 contacts the outermost side edge of the vehicle body opening periphery 6 to seal the gap between the outer peripheral edge of the door frame 2 and the vehicle body opening periphery 6. At that time, the hollow seal portion 114 is in contact with the bulging portion on the inner side of the vehicle rather than the portion where the seal lip portion 116 of the vehicle body opening periphery 6 is in contact, and seals between the door 1 and the vehicle body opening periphery 6. ing.

  In recent years, hidden type doors are often used due to design requirements. However, in the hidden type doors, the width of the side edge of the door frame 2 outside the vehicle is narrowed so that the door 1 and the periphery of the opening of the vehicle body 9, it is necessary to reduce the width of the vehicle exterior vertical wall 2d of the outer panel 2a of the door frame 2 as shown in FIG. ing.

  For this reason, as a mounting structure of the door weather strip 210, there is a structure in which the outer side wall 2d portion of the outer panel 2a of the door frame 2 is reduced and the door molding 250 in which the door molding and the retainer portion are integrated is attached to the door frame 2. is there. In this case, the door weather strip 210 is formed apart from the outer weather strip 222 and the inner weather strip 223 so that the outer weather strip 222 is made smaller and the door molding 250 is formed. There is something to install. The sealing portion of the outer weather strip 222 is also formed in a small lip shape as the sealing lip portion 216, and the inner weather strip 223 is lowered downward on the inner side of the door frame 2 to be mounted on the inner side of the vehicle. Some are attached with a base 211 and sealed with a hollow seal 224 (see, for example, Patent Document 1).

Since the door weather strip 210 is often attached over the entire periphery of the door frame 2, as shown in FIG. 6, the upper side portion 213 and the vertical side portion 214 formed by extrusion molding are formed by molding. Are connected at the corner portion 212 (see, for example, Patent Document 2).
However, due to the design of the automobile body and the door 1, the general cross-sectional shape of the extrusion molding cannot be used over the entire length of the upper side portion 213 or the vertical side portion 214. It is necessary to change the cross-sectional shape of the door weather strip 210 according to the site.

In this case, it is difficult to form the portion of the door weather strip 210 whose shape is changed by extrusion molding, and it is necessary to form the corner portion at the same time as the molding, but the portion is large. As a result, the mold becomes large, the molding is inefficient, and the cost increases.
