摘要:
Both legs (1a, 1b) of a U-shaped bulb are brought into a mutually contacting state or are opposed to each other with a space of gap (31) and end parts (1a', 1b') of the legs are directly put on an end plate (10) so as to form an electric discharge path in the U-shaped bulb. Since the legs (1a, 1b) are in contact with each other within limit of elastic deformation of a connecting part (2a) of the bulb (1), breakage of the bulb is avoidable even when an external force is applied to the bulb so as to bring the legs (1a, 1b) closer.
