<P>PROBLEM TO BE SOLVED: To prevent or suppress a spacer attached to an end of an inner bulb for coaxially supporting the inner bulb to an outer bulb from interrupting light emitted from the inner bulb, causing uneven illumination or shadows and lowering the efficiency of using effective light and to prevent the spacer from falling off the end of the inner bulb or tipping and disfiguring the appearance of a lamp. Ž<P>SOLUTION: The spacer S<SB>1</SB>has a central plate 7 pivoted to an exhaust tube 5 as the exhaust tube 5 protruded to the end of the inner bulb 2 is passed through an aperture 8, and three or more strips 9 each radially branched from the central plate 7. The central plate 7 is formed with a plurality of fingers 10 for securing the central plate 7 to the exhaust tube 5. The strips 9 are each formed into a curved shape for coaxially supporting the inner bulb 2 to an outer bulb 3 near the end of the inner bulb 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
