Description

Door seal

The present disclosure relates to a door seal in an automobile, and more particularly to a seal structure between a door and a vehicle body in a vehicle having a wheel arch at the opening / closing part of the door.

Conventionally, in a vehicle such as a so-called SUV (Sport Utility Vehicle), as shown in FIG. 1, a wheel arch 120 is provided at an opening / closing portion of a door panel 110 for people to get on and off, and dust rolled up from a tire. A seal structure is provided in the wheel arch 120 in order to prevent mud and water (hereinafter abbreviated as mud and the like) from entering the inside of the vehicle 100. As a sealing structure in the wheel arch 120, when the door 110 is closed, a sealing member having an elastic force provided on the door side abuts on the vehicle body and elastically deforms to seal between the door panel 110 and the vehicle body. The technique is known (see, for example, Patent Document 1).
