Abstract
A color selection mechanism of a cathode-ray tube is formed in such a manner that a large number of strip-shaped grid elements are stretched across a frame which has a pair of opposed support members and a pair of elastically-providing members fixed between the support members. In this color selection mechanism, the geometrical moment of inertia of each of the support members can be changed stepwise from a central part of each of the support members to each of end parts thereof by changing a ratio of a longitudinal dimension to a lateral dimension of an L-shaped section of each of the pair of support members stepwise. As a result, it becomes possible to increase the rigidity at the central part of the frame of the color selection mechanism and thereby improve the performance of the color selection mechanism of the cathode-ray tube.
