<p>PROBLEM TO BE SOLVED: To improve the service life of a car by traveling by compactly contracting a car length rail and a boned sheet on a roof at traveling time, and completely covering the whole car with the sheet by stretching out the car length rail and the boned sheet at parking time. SOLUTION: A car length rail on a roof and a car body outer peripheral rail are arranged, a rotary body 7 is inserted inside a groove shape to be formed as a nonslipping-out structure, and a car width bone 4 for a roof and a car body outer peripheral car height bone 18 are connected to an outer peripheral car length rail 1 and a car body outer peripheral rail 19 by a rotary body pressing-down part 8. The car length rail inside of the outer peripheral car length rail 1 is incorporated inside or outside a C groove shape to be formed as an extensible-contractible structure. An inside car length rail of a roof part and the bone 4 for a roof are made horizontal, and a central part is formed in a slightly high gentle angle shape to improve drainage of rain on the roof.</p> |
