  • Sealing member and method of installing the same
    Patent number: 7775581
    Abstract: A sealing member that mitigates oscillating noises and its installation method is provided. In the sealing member for covering an opening formed at a door inner panel, at least one bead is installed at a covering portion facing the opening. Thus, the stiffness of the covering portion of the sealing member is increased. It is therefore possible to prevent the covering portion from oscillating, thereby inhibiting the sealing member from generating the oscillating noises.
