A coupling structure of a door weather strip, in which the door weather strip is coupled to a frame of a door of an automobile, the door weather strip comprising:
- a first extrusion-molded part configured to be operably coupled to an upper side part of the frame;
- a second extrusion-molded part configured to be operably coupled to a vertical side part of the frame;
- a die-molded part configured to connect the first and second extrusion-molded parts on a corner part;
- a first part of the die-molded part closer to the upper side part, the first part comprising:
- a first installation member configured to be operably coupled to a first retainer of the door;
- a first hollow seal member which extends from the first installation member, the first hollow seal member being configured to seal a gap between a peripheral edge of a door opening of an automobile body of the automobile and the door;
- a first sub seal lip which extends from at least one of the first hollow seal member or the first installation member, the first sub seal lip being configured to make elastic contact with the peripheral edge of the door opening;
- and
- a first extended part which extends toward a rear part of the corner part from the first sub seal lip;
- a second part of the die-molded part closer to the vertical side part, the second part comprising:
- a second installation member configured to be operably coupled to a second retainer of the door;
- a second hollow seal member which extends from the second installation member, the second hollow seal member being configured to seal a gap between the peripheral edge of the door opening and the door;
- a second rear seal lip which extends from the second installation member, the second rear seal lip being configured to make elastic contact with a rear surface of the vertical side part;
- and
- a second extended part which extends toward the rear part of the corner part from a connecting part between the second installation member and the second hollow seal member closer to the exterior of the automobile, a lower end of the first extended part and an upper end of the second extended part being connected, the second extended part having a rigid member embedded therein;
- and
- the rigid member which has a tabular shape, the rigid member including a body, and the body having:
- a single anchoring part which protrudes from the body of the rigid member, the anchoring part being configured to be fit in a hole formed on the vertical side part;
- and
- a protrusion provided below the anchoring part, the protrusion being flush with the body, the protrusion extending toward a front part of the automobile body, and the protrusion being capable of abutting with an outer part of the second retainer.
