<p>PURPOSE:To prevent rain water from flowing down as well as to prevent wind whiz from occurring in a drip molding installed along a drip rail by providing a flap which sets the dericking motion accompanied with the coming in and out of fluid. CONSTITUTION:When a car is running in the rain, if fluid is introduced into a cavity 16, the cavity 6 expands for making a flap 13 rise. Consequently, a groove 9 is formed between the flap 13 and a roof panel 8 for gethering running rain water into the groove 9 so as to prevent it from flowing down to a side window. On the other hand, when the car is running in an usual condition, particularly at high speed, if the fluid in the cavity 16 is discharged out, the cavity 16 contracts for causing the flap 13 to lie down so as to strike it into contact with a roof panel 8. Accordingly, as a smooth surface is formed, air turbulence is prevented for preventing wind whiz from occurring.</p> |
