<p>PURPOSE:To make it possible to easily and surely prevent the adhesion of frost onto the front glass of a car by covering the front glass with a screen subjected to water proof treatment while properly drawing out the screen from a screen housing part which is mounted on the roof front area of the car and into which the screen has been wound. CONSTITUTION:A screen 1 having the proper width and subjected to water proof treatment is wound around a rotary shaft and is made possible to be housed in a housing part 3, while to rotary shafts 2, 2' protruding from both ends of said housing part, a spring 4, etc., a gear shaped drum 5 and a brake shoe 6, etc., are rotatably attached such that they are interlocked, allowing a winding mechanism part 7 to be constituted. Further, the winding mechanism part 7 is covered and a fixing part 9 which forms a sling stopper 8 is provided on the lower end of the outside thereof. When using it, after this device is attached to the sling stoppers while hanging the sling stopper 8 on the both sides of the front area of a car roof 14, and thereafter a sling lever 10 is inclined to make the rotary shaft 2 rotatable. And, by stretching the screen 1 over the front glass 15 while drawing out the screen 1 from the housing part and by hanging the end of the screen round a wiper shaft 16, etc., the adhesion of frost to the front face glass 15 can be prevented.</p> |
