  • Publication number: 20150336450
    Abstract: A vehicle ceiling includes a roof panel, a ceiling member attached to the roof panel to face toward a vehicle interior and an opening/closing mechanism attached to the ceiling member. The ceiling member is formed with an opening that corresponds with an aperture in the roof panel. The opening/closing mechanism is configured to deploy and reciprocate a sheet member between in a closed state and an open state. The sheet member, in the closed state, covers the opening in the ceiling member to suppress light entrance into the vehicle interior. The sheet member, in the open state, is stowed away from the opening in the ceiling member to permit light entrance into the vehicle.
