Since the conventional shadow mask support structure is constructed as shown in FIGS. 3 to 5, there are many welding points, for example, 16 places, which may cause variations in welding conditions and influences of jigs. It is easy to receive, the support structure consisting of spring parts and bimetal parts is tilted, and the thickness after welding is likely to vary, so the mounting accuracy is poor, and the shadow mask assembly is supported with flatness centered on the panel glass. It was difficult to do. Although the technique disclosed in the above publication is related technology, it cannot solve the above problems.

According to this embodiment, the three supporting structures can be formed by using the commercially available double-joint metal, and the welding of the spring parts and the bimetal parts is not necessary, and the welding of the six parts in total is required. It can be omitted. As a result, not only the assembling process can be simplified, but also the deterioration of the assembling accuracy accompanying the welding work can be greatly reduced. Further, when all four supporting structures are formed by the joint metal, the existing assembling apparatus cannot be used and a special capital investment is required, but in the case of this embodiment, the fourth supporting portion is not used. Since the support structure remains in its conventional form, existing assembly equipment can be utilized and no special investment is required.
