摘要

PURPOSE:To downsize a lighting fixture by inserting the sandwiching protrusion of a plug, which supports a lamp bulb attachably and detachably, into the through notch of a fitting portion. CONSTITUTION:A major arc-like fitting rim 9 having an opening 9a in its one side edge is provided in the plate-like fitting portion 5 of a main part 3, and a through notch 10 is formed in the fitting rim 9. A sandwiching protrusion 19 is provided on a plug 15 supporting a lamp 16 so as to be detachable, and a lamp bulb 16 is fitted to the main part 3 when the protrusion 19 is inserted into the notch 10. Since the fitting rim 9 is formed into a major arc but not a circular arc, the width dimension of the fitting portion 5 forming the fitting rim 9 can 5 be reduced so as to downsize a lighting fixture.
