PURPOSE:To simplify lamp exchange so as to stabilize switching operation by attaching, detaching the control piece portion of a lamp holder to the lighting fitting main body while using a switch portion located at the center portion of a control as a guide, the lamp holder holding annular lamps by means of lamp sockets and holding portions. CONSTITUTION:Big and small annular lamps 22, 23 are held at respective holding portions 32, 33 of a holding arm 25 by connection of lamp pins to the respective lamp sockets 27, 30 of the holding arm 24 of a lamp holder 21. Both lamps are fittingly held simply by pulling the control piece portion 35 of the holder 21, inserting the piece portion 35 into the engagement recessed portion 5 of the lighting fitting main body 1, and positioning an elastic locking piece 34 in the locking hole 6 of the main body so as to release its pressed state. In this case positioning of the lamps is simplified since the through hole 37 of the holder 21 is guided to the pullswitch engagement protruding portion 7 of the switch portion located at the center portion of the main body. Also, because the protruding portion 7 can be installed at the center of the main body 1, oscillation caused by operation of the pulling cord 9 of the pullswitch is reduced. |
