Abstract

PURPOSE: To ensure a prescribed lap margin between a seal part and a body panel so that an inferior seal can be eliminated, by preventing crush of the seal part in a corner part of a roof panel, by a shape of a weather strip itself. CONSTITUTION: A weather strip 11 is integrally constituted by a trim part 12 mounted on a peripheral edge of a roof panel 5 and by a seal part 13 of hollow shape brought into press contact with an opening part 3 of a body panel 2. A press contact part 13a protrusively curved to the outside is provided in an upper half part of the seal part 13, and a press contactless part 13b protrusively curved to the inside is provided in a lower half part of the seal part 13. When the weather strip 11 is curved in a corner part of the roof panel 5, according to extension of the seal part 13, only this press contactless part 13b is deformed to the inside. Accordingly, the press contact part 13a of the seal part 13 maintains almost an original form.
