Abstract
A mask support including a multiplicity of retainers is disclosed which supports a shadow mask assembly consisting of a shadow mask disposed in front of a fluorescent screen formed on the internal panel surface of a color picture tube and of a frame to hold the shadow mask. Each of the retainers comprises a spring member secured to the side wall of the frame and a rigid support member for supporting most weight of the shadow mask assembly, which rigid support member is attached to the spring member and engages a fixed member fixed on an internal surface of the picture tube. The spring member provides an action which causes the support member to be displaced towards the internal surface of the color picture tube so that the support member and the fixed member are firmly engaged.
