ABSTRACT:
A fluorescent luminous device capable of permitting vibration of a filamentary cathode due to any external vibration or shock transmitted thereto to be readily attenuated, to thereby substantially prevent flickering of a display due to a variation in luminance of the luminous section, resulting in improving quality of the display. A part of a vibration adsorbing element provided at the end of a filamentary cathode is separatably contacted with the fixed portion of an envelope in which the element and cathode are arranged.
