By moving to the roof, the opening part is opened, so the moving roof moves on a substantially horizontal surface, so there is little gravity effect such as natural fall, and also to move the moving roof. It has the advantage of requiring less power capacity. In addition, there is no need to provide a scaffold for maintenance and inspection of the power mechanism for moving the movable roof.

がある。The movable roof is divided into left and right from the center, and is connected by a uniaxial rotary coupling mechanism so that the swinging movement can be performed in the left and right direction at a part of the dividing point. Since it is eccentric with respect to it, and the fixed roof direction part of the moving roof is radially cut out around the above-mentioned turning point, it is possible to pull it toward the fixed roof as it is while moving left and right so that these cutouts are closed. it can.
Furthermore, since the tip end portion on the side opposite to the notch is moved along the peripheral edge of the opening, when the tip end portion is pivotally moved along the peripheral edge portion of the opening, the rotary coupling mechanism is directed toward the fixed roof side. Therefore, compared to opening the opening by simply rotating the moving roof member left and right, the opening angle due to the rotational movement of the moving roof member can be made relatively small, and This has the effect of increasing the aperture ratio by reducing the outwardly protruding portion of the fixed roof.

Since the thrust bearing is arranged and the rotational bearing of the movable roof member is supported by the thrust bearing, the movement when the movable roof member is opened and closed is smoothly realized. Further, in the groove, since the rotary shaft center portion of the movable roof member is a rib and the inner and outer peripheral surfaces of the groove lock the inner and outer peripheral surfaces of the rib, the central axis of the flange portion is It is possible to rotatably connect a movable roof member, which is divided into left and right separately in a rotatable state with a radius of, at one point.

The effect of being able to easily respond to oscillating movements due to changes in height or changes in the direction of travel, and the effect of allowing free laying of a guide track on a fixed roof and allowing rotational movements of moving roof members to change freely There is.

A retractable roof in which a substantially circular fixed roof is formed with a substantially circular opening biased to one side, and the opening is covered by a pair of symmetrically movable roofs that can be opened and closed. In the movable roof, the left and right movable roof members are rotatably coupled to each other in a plane by a uniaxial rotary coupling mechanism at a point where the movable roof members are slightly eccentric from the center point of the opening in the fixed roof direction. In addition, the movable roof members are formed with notches radially from the rotary coupling mechanism in the direction of the fixed roof, and the rotary joint mechanisms are rotated so as to close the notched portions. On the fixed roof, a traveling carriage mounted on the tip of the anti-notch side portion of each movable roof member is opened and closed on the fixed roof when the movable roof is rotated to open and close the opening. Guide to rotate and guide along the peripheral edge The road and a plurality of traveling carriages mounted at appropriate intervals on the periphery of each movable roof member are displaced in the front-rear direction due to the pivotal movement of the tip portion and pivotal movement about the pivotal coupling mechanism.
