Abstract
In a video display terminal having a housing and a cathode ray tube mounted in the housing, there is provided shift restricting means for applying a selected level of force between mounting ears of the tube and the housing in a direction generally perpendicular to the central axis of the tube. In a preferred embodiment, angle brackets are mounted inside the housing between the enlarged end portion of the cathode ray tube and inside corners of the housing, and lateral force is applied between the angle brackets and the enlarged end portion of the tube for rigidifying the housing. The lateral force is applied by wedges mounted in the brackets for sliding against the mounting ears, and screws are coupled to the brackets for forcing the wedges against the mounting ears.
