引き起し、動作不能となるなどの問題があった。However, when fixing by resistance welding, welding splash often occurs, so detailed control of the welding conditions for holes to prevent splash generation, a splash collection plate, and a tin splash removal process have been added. In addition, in the splash removal process, if the splash is not completely removed and remains in the vacuum container, it may clog the shadow mask section 5 or cause a short circuit between the poles of the electron gun (not shown), making it inoperable. There was a problem.

[Summary of the Invention] In order to achieve the above object, the present invention provides a contact spring with a convex portion and a guide portion that improve adhesion with a support frame, and also provides a contact spring with a support frame. A common through hole is provided for both, and a spring-like fixing fitting is inserted through the common hole to hold and fix the contact spring.
