Abstract
A weather strip 4 has been equipped with: a trim portion 5 which is mounted on a flange portion 23 provided along a circumference portion of a door opening corresponding to a door 2; and a seal portion 6 having a hallow portion 6a, which is projected from the trim portion 5 to an outer side of a vehicle. The seal portion 6 has been provided with a thicker-thickness portion 41 at a portion which abuts against a peripheral portion of the door 2 when the door 2 is closed. Furthermore, each of a door opening inner circumferential-sided portion and a door opening outer circumferential-sided portion within the seal portion 2, which are located adjacent to the thicker-thickness portion 41, has been constructed as a thinner-thickness portion 42 which is made thinner than the thicker-thickness portion 41. Also, a bridge 34 has been provided on an inner side of the seal portion 6, while the bridge 34 couples the door opening outer circumferential-sided portion within the seal portion 6 to a vehicle outer-sided side wall portion 12 rather than the thinner-thickness portion 42 provided on the door opening outer circumferential side.
