ABSTRACT:
A weather strip for providing a seal between a door opening of a body of a motor vehicle and a door frame, has extruded members and a molded member for connecting ends of the extruded members. Each of the extruded members and the molded member is provided with a base portion, and a tubular sealing portion projecting from the base portion to be pressed by the body of the motor vehicle and the door frame when a door is closed. The tubular sealing portion has a flat board like bridge connecting opposing inner side surfaces of the sealing portion. The bridge extends so as to cross a connection boundary between each of the extruded members, and the molded member in a direction perpendicular to the connection boundary. When the sealing portion is pressed by the body and the door frame, the connection boundary is backed up by the bridge so that an abrupt change in deformed state on both sides of the connection boundary can be reduced or moderated. Accordingly the deformation of the sealing portion becomes uniform throughout the whole length thereof, and continuous sealing performance can be obtained.
