PURPOSE:To improve the stability of a lamp by holding engaging parts of smaller diameter which is formed near ends of a luminous tube and the center curved part of the luminous tube on holding parts and on an elastic holding part respectively. CONSTITUTION:Engaging parts of smaller diameter 3 is formed near the ends of a fluorescent tube 1 which is curved saddle-shaped, and holding parts 12, 14 to hold these engaging parts 3 and an elastic holding part 17 to hold the center of the luminous tube 1 are formed on a holder 8. Thus the luminous tube 1 can be held stably. A play which is required when the luminous tube 1 is mounted which is holded across a stabilizer 7 provided on a space of the luminous tube 1 is obtained with the engaging parts 3 of smaller diameter, the luminous tube 1 can be holded easily on the holder 8, and the possible breakage of the luminous tube 1 when mounting is eliminated. |
