Title:
ELECTRIC DISCHARGE TUBE, MOUTHPIECE, ILLUMINATING DEVICE, DISPLAY, AND TV RECEIVER
Document Type and Number:
WIPO Patent Application WO/2008/001565
Kind Code:
A1
Abstract:
A mouthpiece (50) includes a cylindrical body (51), and elastic holding pieces
(54) projecting to the radial inner side are formed on the body (51). The elastic
holding pieces (54) elastically abut onto the outer peripheral surface of a glass
tube (40). The body (51) of the mouthpiece (50) can accept variances in the outer
diameter dimensions of the glass tube (40), since the body (51) is fitted to the
glass tube (40) via elastic holding pieces (54) which is elastically deformable
in the radial direction. Thereby, the accurate control of the dimensions is not
needed when the glass tube (40) is manufactured, and accordingly, the cost can
be reduced.
