A door weather strip comprising:
- an attachment base part which is attached to a door panel of a vehicle, and has at least a part made of a first rubber;
- a hollow seal part which is made of a second rubber softer than the first rubber, the hollow seal part having a base bottom portion disposed so as to come in contact with an outer surface of the door panel and a circular arc portion which is integrally formed with an upper end portion of the base bottom portion, the circular arc portion structured to contact a vehicle body panel so as to be deflected and deformed in a door closed state;
- and
- a connection part which is made of the second rubber, and connects the base bottom portion of the hollow seal part with the attachment base part,
- wherein the first rubber is buried inside each of the base bottom portion of the hollow seal part and the connection part such that a portion of the first rubber in the base bottom portion is connected to a portion of the first rubber in the connection part while disconnected from the first rubber of the attachment base part;
- wherein a first end portion on a distal end side in a width direction of the first rubber within the base bottom portion extends to and is contained in an area defined within an outer end portion of the circular arc portion of the base bottom portion, the area limited to a segment of the outer end portion disposed to directly contact the outer surface of the door panel, and a second end portion of the first rubber within the connection part extends to a vicinity of the attachment base part within the connection part, and
- wherein an upper surface of the first rubber of the base bottom portion forms an interior surface of the circular arc portion.
