[Conventional technology]

Take the sliding sunroof of a car (hereinafter simply referred to as a sunroof) as an example. When the sunroof is opened, the sunroof can be moved in the front and rear directions through a roughly rectangular opening in the roof panel. The opening is opened and closed. On the outer periphery of the sunroof, A weather strip is attached to seal the space between the opening and the opening when it is closed. ing.

0003 As shown in FIG. 4, this type of weather strip 5 generally has a hollow seal portion 52. The weather strip 5 is equipped with a draining lip 53 extending downward from the bottom surface. The water leaking from the opening is guided to an unillustrated drip groove provided at the bottom of the periphery of the opening. (Utility Model Publication No. 56-49622).

0004 By the way, when a car is running at high speed, a phenomenon occurs where air is sucked into the sunroof 2. The leading edge of is sucked up. When it is sucked up, the sealing force of the hollow seal portion 52 becomes low. If the vehicle is lowered, air may be sucked out from the passenger compartment to the outside of the vehicle, causing noise. There is. Therefore, the weather strip has a part attached to the front edge of the sunroof. , Separately from the draining lip 53, the tip is in contact with the opening edge of the roof 1 to prevent suction noise. forming a seal lip 54 for use in the weather strip 5, and In addition to 52, sealing performance has been added.

[0005] Generally, the manufacturing of the weather strip 5 having this seal lip 54 is carried out by first A weather strip having a draining lip 53 and a sealing lip 54 over the entire length. The seal lip of the part that is attached to the front edge of the sunroof 2 after extrusion molding of the sunroof 2 A method has been used in which the seal lip 54 is left in place and other parts of the seal lip 54 are cut out. child This is especially true if the seal lips 54 are present in the parts attached to the left and right side edges. This is because it becomes a sliding resistance when the sunroof 2 is moved back and forth to open and close.

[0006] However, after extruding the weather strip 5, the seal lip 54 becomes unnecessary. Cutting out important parts one by one with a cutter etc. reduces manufacturing work efficiency. there were. In addition, in order to improve the followability to the opening, the above seal lip is When made of ponzi rubber, the seal lip is highly flexible, so It becomes difficult to remove with a cutter or the like. Furthermore, this sponge rubber seal lip If it is torn, you will not know where it will tear, and you will not be able to tell where it will be torn. The cracked surfaces also become irregular, resulting in poor appearance.
