Abstract
A color CRT has a panel portion with a phosphor screen and a shadow mask structure. The shadow mask structure has a support frame, a shadow mask, and suspension springs attached to corners of the support frame. Studs are embedded in corners of the panel portion for supporting the shadow mask structure. Each suspension spring includes a base member and a spring member. The spring member includes a sloped portion extending axially and bent outwardly, an engagement portion formed with a hole engaged with one of the studs, and a step-like portion provided between the sloped portion and the engagement portion. The step-like portion protrudes the engagement portion toward the stud such that a center of the hole engaged with the stud is displaced toward the skirt portion of the panel portion from an intersection of an axis of the stud with an imaginary plane projected from the sloped portion.
