<P>PROBLEM TO BE SOLVED: To satisfy requirements of the miniaturization and weight reduction of a window plate lifting movement mechanism while improving the wiping capability of a window plate with a seal lip. <P>SOLUTION: When the window plate 13 moves upward, both of the coefficient of dynamic friction and the pressure of the seal lip 22 against a surface of the window plate 13 become smaller than when the window plate 13 moves downward, and a frictional force of the seal lip 22 (a frictional force generated between the seal lip 22 and the window plate 13) becomes smaller than when the window plate 13 moves downward, thus reducing the driving force required to move the window plate 13 upward. In addition, when the window plate 13 moves downward, both of the coefficient of dynamic friction and the pressure of the seal lip 22 against the surface of the window plate 13 become larger than when the window plate 13 moves upward, and the frictional force of the seal lip 22 becomes larger than when the window plate 13 moves upward, thus reducing the load applied to the window lifting movement mechanism 17 (a load by the weight or the like of the window plate 13). <P>COPYRIGHT: (C)2011,JPO&INPIT |
