To prevent abnormal sounds made by the vibrations of the tip of a seal lip of the molding for a window plate of a vehicle which are created when the air is sucked out from the inner cavity by the difference in pressure between the inside and the outside of the seal lip when the vehicle runs at high speeds, a seal lip body 4a extends in the direction of a vehicle body panel P from the leg of the molding 1 for a window plate and a folded-back lip 4b is consecutively integrally formed such that it folded back in the opposite inward direction from the tip of the seal lip body 4a into the cavity 5 between itself and the vehicle body panel P and extends along the vehicle body panel P. When the vehicle runs at high speeds, even if the seal lip 4a is moved up by the difference in pressure between the inside and the outside of the seal lip body 4a, the folded-back lip 4b is pressed on the vehicle body panel P and thus the air does not leak from the cavity 5. Therefore, it can prevent the abnormal sounds which are produced when the air leaks.
