A weatherstrip includes: a trim portion and a seal portion. The trim portion includes: a main body portion including a first and second side wall portions provided on a vehicle outer side and a vehicle inner side, respectively; a first and second holding lips extending from the first and second side wall portions, respectively; and a first extended wall portion extending from a distal end portion of the first side wall portion. In a trim portion attaching direction, a distal end portion of the first side wall portion is positioned at, or on the weatherstrip inner circumferential side of, a boundary portion between the trim portion and an inner circumferential surface of the seal portion, and a distal end portion of the second side wall portion is positioned on the weatherstrip inner circumferential side of a distal end portion of the first extended wall portion. |

1. A weatherstrip, comprising:
an insertless trim portion attachable to a flange portion which is provided along a circumferential edge of an opening portion of a vehicle body of a vehicle and which includes a first side surface facing toward an outside of the vehicle and a second side surface facing toward an inside of the vehicle; and a seal portion which protrudes from the trim portion toward the outside of vehicle and includes a hollow portion formed therein, and which is pressed by a circumferential edge portion of an opening and closing member configured to open and close the opening portion of the vehicle body when the opening and closing member is closed, wherein at least a part of said weatherstrip in a longitudinal direction comprises an extruded portion formed through extrusion, and the weatherstrip is attached such that the extruded portion attaches to at least one of a plurality of corner portions of the opening portion, wherein the trim portion comprises:
a main body portion which comprises a first side wall portion provided on a vehicle outer side, a second side wall portion provided on a vehicle inner side, and a connecting portion which connects the first side wall portion and the second side wall portion such that the main body portion has a substantially U-shape in a cross section, and which comprises a solid material or a foamed material;a holding lip which extends from the second side wall portion toward the outside of the vehicle so as to be pressed by the second side surface of the flange portion when the trim portion is attached to the flange portion, and which comprises a solid material or a foamed material;another holding lip which extends from the first side wall portion toward the inside of the vehicle so as to be pressed by the first side surface of the flange portion when the trim portion is attached to the flange portion, and which comprises a solid material or a foamed material; anda first extended wall portion which extends toward a weatherstrip outer circumferential side from a distal end portion of the first side wall portion, and which comprises a sponge material, wherein the seal portion includes a sponge material, and comprises:
a first end portion on a weatherstrip inner circumferential side, which is connected to the first side wall portion; anda second end portion on the weatherstrip outer circumferential side, which is connected to the first extended wall portion, wherein the distal end portion of the first side wall portion is positioned at a same position as, or on the weatherstrip inner circumferential side of, a position of the second end portion of the seal portion which forms a boundary portion between the trim portion that faces the hollow portion and an inner circumferential surface of the seal portion with respect to a trim portion attaching direction, wherein a distal end portion of the second side wall portion is positioned on the weatherstrip inner circumferential side of a distal end portion of the first extended wall portion with respect to the trim portion attaching direction, wherein the weatherstrip further comprises a second extended wall portion which extends toward the weatherstrip outer circumferential side from a distal edge of the distal end portion of the second side wall portion substantially along an extending direction of the second side wall portion, and which includes a sponge material, and wherein a distal end portion of the second extended wall portion is positioned on the weatherstrip inner circumferential side of the distal end portion of the first extended wall portion with respect to the trim portion attaching direction.
