<p>PURPOSE:To improve sealing performance by making a weatherstrip adhere closely to a door and contract at the time of opening of the door, and to prevent a half-closed door at the time of closing of the door from occurring after that, by expanding the weatherstrip by increasing inner pressure of the same at the time of closing of the door. CONSTITUTION:When a side door 2 is opened, it is sensed by an opening and closing door sensor 42 and a discharge side solenoid reed valve 32 is opened through a control circuit 40. An inner space 4a of a weatherstrip 4 is connected with the atmosphere through an air line 31 because of the above, through which the weatherstrip 4 is contracted. As the weatherstrip does not turn into a state of closed door resistance as it is being contracted when the door 2 is closed under this condition after that, the door 2 is prevented from becoming half- closed state. When the door 2 is closed completely and a closed door state is sensed by the opening and closing door sensor 42, a feed side solenoid valve 23 is opened then, compressed air in a reservoir 24 is fed into the inner space 4a and the weatherstrip 4 is abutted against the side door 2 closely due to swelling.</p> |
