20150082710 | TRIM FOR VEHICLE - 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. | 03-26-2015 |
