An automatically extendible and retractable awning for a vehicle. Awning material is connected at one end to a recreational vehicle and at the other end to a roller assembly, said roller assembly which is movable between a stored position where the awning material is wrapped around the roller assembly and is positioned adjacent the recreational vehicle and an extended position where the awning material extends away from the recreational vehicle. Mechanism provides energy to the roller assembly to effectuate movement of the roller assembly between the extended and the stored positions. Two support arm assemblies, each being mounted at one end to the recreational vehicle and at the other end to the roller assembly are movable between a stored position where the support arm assemblies are close and generally parallel to the side of the recreational vehicle and an extended position where the support arm assemblies extend away from the recreational vehicle. Two rafter arm assemblies are mounted at one end to the recreational vehicle and at the other end to an associated one of the support arm assemblies and are movable between a retracted position and an extended position where the rafter arm assemblies assist holding the roller assembly in the extended position thereof with the awning material unrolled and extending away from the recreational vehicle. Mechanism using pressurized fluid for operating the support arm assemblies to their extended position when the roller assembly is moving to its extended position thereof. Devices connect the mechanism to a source of fluid for automatically extending the awning.
