the weather strip
being provided on a peripheral edge portion of the door of the automobile, and
made of an elastic material and sealing a gap between the peripheral edge portion of the door and a peripheral edge portion of an opening portion of a vehicle body,
wherein
the weather strip is formed by integrating a hollow seal portion and an attachment base portion together,
the hollow seal portion
being elastically deformed by coming into contact with the peripheral edge portion of the opening portion of the vehicle body, and
the attachment base portion
including a seal lip portion disposed on an outer side of a passenger compartment of the hollow seal portion and elastically deformed by coming into contact with the peripheral edge portion of the opening portion of the vehicle body on an outer side of the passenger compartment than the hollow seal portion, and
being disposed on an outer side of the passenger compartment than the hollow seal portion,
a sticking material is provided on a surface of the hollow seal portion closer to the door frame,
the door frame includes a sticking surface on which the sticking material is stuck, and a protruding portion protruding and provided on an outer side of the passenger compartment than the sticking surface,
the attachment base portion includes a portion composed of a solider material than the seal lip portion,
the solider portion includes a fitting portion fitted to the protruding portion, and
a deformation origin portion serving as an origin of deformation is provided between the hollow seal portion and the attachment base portion of the weather strip.
