Thereby, the rotation of the rotor 33 is regulated by the rotation lock component 35. At this time, a part of the rotation lock part 35 is located between the first base 21 of the straight tube lamp 20 and the rotor 33.

  Further, when the straight tube lamp 20 is removed, the rotation lock component 35 is slid in a direction away from the rotor 33, whereby the restriction of the rotor 33 is released. Thereby, the rotor 33 and the straight tube lamp 20 can be rotated and removed.

  As described above, in the present embodiment, the rotary lock component 35 is slid to the rotor 33 side in a state where the straight tube type lamp 20 is mounted to the first socket 30, and contacts the projection 332 of the rotor 33. Alternatively, the rotation of the rotor 33 can be regulated by bringing the rotor 33 into close proximity. Thereby, even when the straight tube lamp 20 is provided with a heat sink and is eccentric, the rotation of the straight tube lamp 20 due to vibration or the like can be restricted, and the drop can be suppressed. Further, by restricting the rotation of the rotor 33 of the first socket 30, there is no need to provide the straight tube lamp 20 with a dedicated base, and versatility is enhanced.
