  • Patent number: 9327585
    Abstract: When a thickest part of a flange is being inserted into an attachment portion of a weather strip, a main body portion of a holding lip having a smaller coefficient of dynamic friction than that of a contact portion firstly contacts with the flange. Therefore, a frictional force of the holding lip (main body portion) with respect to the flange is made small, and the insertion force is made small to that extent. When the attachment portion is attached to a thinnest part of the flange, the contact portion of the holding lip having a greater coefficient of dynamic friction than that of the main body portion contacts with the flange. Therefore, the frictional force of the holding lip (contact portion) is made large, and the holding lip is made difficult to slip with respect to the flange.

  • Patent number: 8893438
    Abstract: A weather strip is provided. The weather strip is arranged so as to intersect a portion joined by overlapping a plurality of panels, and is provided with a tip projection portion which projects onto an extension line of the exterior side wall portion from the tip of an exterior side wall portion of an attachment portion. The tip projection portion is formed from a material which deforms easier than a material forming the sealing portion and is formed in a shape which becomes thin towards a projecting direction with a width dimension which does not exceed the thickness of the tip of the exterior side wall portion in a cross section along the width direction of the attachment portion, and when the attachment portion is attached to the flange, the tip projection portion stretches in the longitudinal direction of the attachment portion and comes into contact with the panels.
