PURPOSE:To prevent wind whiz from occurring in a roof molding installed along a groove in a recess on the roof side by providing a flap which is capable of the dericking motion, to a molding main body whereby flowing the liquid in and out of a cavity for enabling the dericking motion of the flap. CONSTITUTION:When a drive switch for a wiper is turned on in the rain, the fluid in a cylinder 33 is highly pressurized by means of a piston 34 for transmit ting thereof to a tube 15 so as to expand a cavity 16. Herewith, a flap 13 rises for preventing rain water from flowing down to a side window. And when rain stops, if the drive switch is turned off, the fluid in the tube 15 is sent back by the movement of the piston 35 for making the cavity 16 contract. As a result, the flap 13 is restored to its original condition for smoothing the surface. Accordingly, air flows smoothly for preventing wind whiz from occur ring. |
