ABSTRACT:
An openable roof includes a plurality of rotationally movable roof members and at least one linearly movable roof member. Each of the rotationally movable roof members is of a generally sectorial shape in a two-dimensional projection. The sectorial shape has a radially outer edge portion. The outer edge portions of the rotationally movable roof members are movably disposed on an outer arcuate support. Accordingly, each of the rotationally movable roof members is able to revolve around an axis of the arcuate support so as to participate to open and close a sectorial opening portion provided by the arcuate support. The linearly movable roof member has a generally V-shaped edge portion. The V-shaped edge portion cooperates with the arcuate support to define the sectorial opening. The linearly movable roof member is movably disposed on a plurality of linear supports so as to participate to open and close a larger opening portion which is larger than the sectorial opening.
