ABSTRACT OF THE DISCLOSURE An openable roof includes a plurality of fixed roof members and a plurality of movable roof members. Each fixed roof member is a portion of a sphere, with a subsection removed so as to produce an opening. Each movable roof member is the above-mentioned removed subsection with a further subsection removed. The fixed roof members constitute the lower portion of the openable roof so that a complete opening results from coincidence of the openings. The movable roof members are mounted on the lower portion of the openable roof in such a manner that each movable roof member moves along a track formed along the rim of the opening of the corresponding fixed roof member.
