Description

  The present invention relates to a weather strip for fixed glass that is attached to the periphery of a fixed glass of a vehicle door.

  Conventionally, some doors of vehicles such as automobiles have a fixed glass attached. The fixed glass is fitted into the opening of the door after a fixed glass weatherstrip for sealing the fixed glass is mounted on the peripheral edge thereof.

  The weather strip for fixed glass includes a main body portion having a substantially U-shaped cross section having an insertion groove into which the fixed glass is inserted on the inner peripheral side. The main body portion includes a base portion and a vehicle inner side wall portion and a vehicle outer side wall portion extending from both ends of the base portion.

By the way, in the lower side part of the weather strip for fixed glass, it is assumed that water enters from between the vehicle outer side wall part and the fixed glass. And if water permeates into the insertion groove portion, the water may ooze out to the vehicle inner side through the base portion and the vehicle inner side wall portion. This is because there is almost no gap between the side wall portions and the fixed glass (very small), and even a small amount of water is sucked upward by capillary action. On the other hand, there is a technique of forming a water drain hole in the insertion groove portion of the weather strip for fixed glass as a measure for preventing water from entering (see, for example, Patent Document 1).
JP 2006-248505 A

  However, in the above technique, since it is necessary to ensure the shape, it is not possible to continuously form the drainage hole over the longitudinal direction. In other words, the drain hole must be partially formed in the lower side. For this reason, in the site | part in which the drain hole of the lower side part is not provided, there exists a possibility that water may still be sucked up by a capillary phenomenon and oozes out to the vehicle inner side.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a weather strip for fixed glass that can more reliably prevent water from seeping out into the vehicle interior. There is.
