Getter support

摘要

A getter support capable of permitting a getter to be compactly arranged in a vacuum envelope while keeping a space for the getter minimized. The getter support includes holders for vertically interposedly holding a getter, first support legs formed integrally with the holders so as to downwardly extend therefrom, and second support legs formed integrally with the holders so as to upwardly extend therefrom. The getter support is fixedly arranged in a getter chamber while being pressed by elasticity of the second support legs. The second support legs are varied in deflection depending on contact thereof with a second substrate of an envelope. This permits a distance between an upper surface of the getter and the second substrate of the envelope to be constantly kept at a desired value.
