ABSTRACT:
An openable roof includes a plurality of movable roof members. Each of the movable roof members is of a generally sectorial shape in two-dimensional projection. The sectorial shape has a radially outer edge portion and a radially inner edge portion. The outer edge portion of the movable roof member is movably disposed on an outer arcuate support. The inner edge portion of the movable roof member is movably disposed on an inner arcuate support. The outer and inner arcuate supports are disposed concentrically about a common axis. Accordingly, each of the movable roof members is able to revolve around the axis of the arcuate supports so as to participate to open and close a sectorial opening portion provided between the arcuate supports.
