A sun roof is arranged to descend without tilting (thus avoiding abrasion of the weather stripping) into a space below the roof panel and thereafter to slide into a housing for same. The actuating mechanism either reduces or maintains the distance between the shoes, which serve as bogies for the roof, to induce smooth sliding of the unit when moving in and out of the storage position, and applies the driving force to the leading pair of shoes to further increase the smoothness of the sliding when moving the unit from the storage housing. When tilting the sun roof for ventilation, the mechanism lifts one end and maintains the other end essentially stationary by applying a slight lift which offsets the tendency for the other end to sink due to the tilting. Again the weather strip is protected from abrasion.
