Therefore, there is no need to perform any particular positioning during assembly, and by installing the stabilizer C34) at a predetermined position, the stabilizer C34) is automatically placed at the predetermined position.

The temperature fuse (terminal board (431) is positioned so that it is in contact with the coil (7) of the ballast Cl41, which is the most likely to catch fire among electrical parts, so it can reliably prevent the ballast coil (to) from catching fire. .Also, place the glow starter (461, noise prevention capacitor (10), Therefore, the heat from the discharge lamp +11 and the safety lamp 04), which become high temperatures, is blocked.

Problems such as malfunction due to high width and short life due to deterioration are solved.

The engagement between the second shell (a) and the first shell Q16 is as follows.

By pushing the second shell (A) into the first shell (1 (to)), the recess f'J3K of the first shell fllD
? The projections □□□ of the shell (A) of J2 are configured to elastically engage with the meshing force. Therefore, the engagement of the two split shells (1 second, (A)) is strong against vertical forces as well as against torque applied when attaching and detaching the discharge lamp (1).

It has a sufficient usurpation to withstand. In this case, if you apply adhesive to the engaging part of the two split shells for 6 seconds,
It is safe to say that the number of robberies involved will increase further. Also,
If the shell part of the second shell does not engage with the first shell Ila,
Ballast hanging part tB is ballast iron core cA two discharge lamps +1
It stands in a position to support the first side. Therefore, even if the engagement between the first shell and the second shell (a) is disengaged, the ballast 0a is attached to the inner circle of the second shell screwed onto the fixed light bulb socket (not shown).
