PURPOSE:To stabilize the installation by forming a lamp holding body by use of an arm part to be connected to the base parts of lamps and two arms for holding the lamps. CONSTITUTION:Lamps 16, 17 are stably held in a level with a holding body 11 by three points of arm parts 13, 14, 15. When the holding body 11 having the lamps 16, 17 installed and held thereby is fitted to the fitting recessed part 5 of an equipment body 11 and rotated, the locking part 25 of a conductive locking piece 24 is engaged with the locking piece disposed along the inner edge part of a locking hole 6, and mechanically locked in such a manner as to be capable of being locked and removed, lamp sockets 20, 21 are electrically connected to a lighting circuit, and the holding body 11 is fitted to and held by the fitting recessed part 5. When the holding body 11 is rotated in the opposite direction to exchange lamps, the locking between the locking part 25 of the locking piece 24 and the hole 6 is released to remove the holding body from the recessed part 5 of the main body 1, whereby the lamps 16, 17 can be separated from the body 1 in the state installed to the holding body 1, and lamp exchange can be easily conducted. Hence, the lamp exchange is facilitated, and the lamps can be stably installed in a level. |
