<P>PROBLEM TO BE SOLVED: To provide a door which can be closed tightly without acceleration or an impact when it is closed, can be opened with a weak force and can prevent a finger from being caught as it stops before closing and when a strong wind blows. <P>SOLUTION: The door is provided with a wheel moving along a running surface, a drive part including a spring which works strongly only at the moment of closing and loosens after the closure, two links connecting it to the door, and a reduction gear which works in a manner that the spring shrinks gradually without shrinking in a moment. <P>COPYRIGHT: (C)2009,JPO&INPIT |
