Abstract
A hingeless ventilator is provided for ventilating a compartment and includes a frame for attaching about an opening in the wall of the compartment. A closure member is swingable against an outer side of the frame for opening and closing the opening. Guide members extend from the frame into the compartment and arm members extend from the closure member through the opening. A holding mechanism is configured with the arm members and guide members to supply a closing tensile force to the closure member. The closure member and the arm members are formed from a unitary plate with the arm members bent at essentially right angles to a base portion of the plate. The closure member includes a cover member, preferably formed of a plastic material, attached to the outer surface of the base portion.
