PURPOSE:To absorb the dispersion in the dimensions of opening margin by passing the bulge of the opening end of a globe into the groove formed by the respective slant and angle of the holder and the cover mutually fixed by hooking claws so as to fix the globe. CONSTITUTION:A holder 1, to which a nonlinear fluorescent tube 4 is attached freely in mounting and removal, is fixed to the cover 3 through the hooking claw 11 of the cover 3, and a groove is formed by the slant 10 of the holder 1 and the angle 12 of the cover 3. By passing the bulge 13 at the brim of the opening through this groove, the gloove 2 is fixed. By this constitution, the dispersion in the dimensions of the opening margin of the globe is absorbed, and it becomes the bulb base type fluorescent lamp wherein the economical efficiency is elevated. |
