    • In an electron tube including vibration absorbers for linear members such as filaments, a vibration absorbing means that is made of a vibration absorber with a large vibration absorption effect, has a simple configuration, and is attachable easily to filaments is provided. The vibration absorbing means is formed of a holder 231, a vibration absorber 241, and a getter shielding member 251. These three members are attached to a shielding electrode S overlying the front substrate 111 to dispose the vibration absorber 241 between the holder 231 and getter shielding member 251. The vibration absorber 241 is mounted to slide or rotate between the holder 231 and the getter shielding member 251. The vibration absorber 241 has an aperture 2413 in which the filament is engaged. The bottom (apex) of the aperture 2413 is formed eccentrically. The vibration absorber 241 is in line contact with the shielding electrode S, as shown in FIG. 3(c).
    • 在包括诸如长丝的线性元件的减振器的电子管中,提供一种由具有大的振动吸收效果的减震器制成的振动吸收装置,具有简单的结构,并且易于连接到细丝上。 振动吸收装置由保持件231,减振器241和吸气剂屏蔽构件251构成。 这三个构件附接到覆盖在前基板111上的屏蔽电极S,以将振动吸收器241设置在保持器231和吸气剂屏蔽构件251之间。 安装振动吸收器241以在保持器231和吸气剂屏蔽构件251之间滑动或旋转。 振动吸收器241具有接合灯丝的孔2413。 孔2413的底部(顶点)偏心地形成。 如图1所示,振动吸收器241与屏蔽电极S线接触。 图3(c)。
