Abstract: A tilt-up device tilts a rear end of a movable roof upwardly when the movable roof is moved from a normal position above the passenger's compartment of an automobile. The tilt-up device is mounted on a surface, which faces the passenger's compartment, of a fixed roof substantially centrally thereon in a transverse direction of the automobile body, and is positioned in front of a seal on the fixed roof. A trunk lid lifting and lowering device is mounted in a trunk and connected to an end of a trunk lid for selectively lifting the trunk lid away from a trunk and lowering the trunk lid toward the trunk. The trunk lid lifting and lowering device has a stopper device for inactivating the trunk lid lifting and lowering device when the trunk lid is locked by a lock device with the trunk lid lowered.

Abstract: A roof is opened and closed by utilizing a trunk lid for opening and closing a trunk room. The trunk lid can be raised and lowered while it is held substantially horizontal. The trunk lid is provided with a roof slide unit for moving the roof in longitudinal directions.When opening the roof in a closed state, the trunk lid is raised to a position behind the roof, and the roof is moved rearwardly by the roof slide unit to be supported by the trunk lid. Then, the trunk lid is lowered down to a position to close the trunk room. This brings an end to an operation of opening the roof. A reverse procedure may be taken for closing the roof.
