PURPOSE:To use a switch portion and a lighting fitting insertion portion as positioning members to be used when a holder is attached/detached to/from the lighting fitting main body and also reduce oscillation of the main body by means of switching control by providing a switch portion protrusively at the center portion of the engagement recessed portion of the lamp holder of the lighting fitting main body, and forming in the holder a fitting insertion portion corresponding to the recessed portion. CONSTITUTION:Elastic locking pieces 34 located on both sides of a lamp holder 21 to which a lamp is mounted are dislockably and mechanically locked in the locking hole 6 of the main body 1 and held by engagement of the lamp holder 21 with the engagement recessed portion 5 of the lighting fitting main body 1. In this case, a through hole 37 provided at the center of the holder 21 is fitted over a pullswitch fitting protruding portion 7 so that it serves as guide for positioning. The pull cord 9 of the pullswitch is drawn out from the hole 37. oscillation of the main body is reduced even at control of the pull cord 9 since the cord 9 is located at approximately the center of the main body 1. In the case of exchanging lamps, because operation of the locking mechanism allows the holder 21 to be detached from the main body 1 with a lamp mounted thereto, lamps are easily exchanged at low positions. |
