PROBLEM TO BE SOLVED: To absorb a fluctuation in a diameter of a lamp, and to easily replace the lamp by providing a holder formed in a thin plate shape out of a comparatively highly springy flexible construction material and forming the curved engaging piece part for engaging the installing piece part with one end and engaging a bulb of an annular fluorescent lamp with the other end and a holder support for installing the holder through the installing piece part. SOLUTION: A holder 31 and a holder support 32 are integrally combined and unitized through the installing piece part 33 of the holder 31. Since the holder 31 is formed in a thin plate shape out of an easily deformable flexible construction material, even if these are a fluctuation of about ±5 mm in a diameter of an annular fluorescent lamp 1 to the standard size, the annular fluorescent lamp 1 can be held by absorbing the fluctuation. Since the holder can be easily, largely and elastically deformed at mounting/demounting time of the annular fluorescent lamp 1, even in replacing the annular fluorescent lamp 1 having a small diameter to the standard size the annular fluorescent lamp can be easily installed and removed. |
