The top plate 28 is in contact with the one surface 27a of the flat mounting panel 27. The top plate 28 is formed with a cylindrical tubular projection 29 that projects toward the globe 21 along the axis 23. An external thread is formed on the outer circumference of the protrusion 29. The rotation drive mechanism 25 housed in the main body case 26 is driven by the motor 31 attached to the chassis 30, and the rotational force from the motor 31 is transmitted to rotate around the axis 23, and the protruding portion 29.
And a rotor 32, which is a rotary connection portion that inserts through. The rotor 32 has an insertion hole 33 formed along the rotation axis. The insertion hole 33 has a chassis 30 and a nut 34.
The shaft 35 fixed by is inserted. The rotor 32 is axially supported by a shaft 35 via a suitable bearing or the like. Further, a gear portion 37 that meshes with a pinion gear 36 fixed to the rotation shaft of the motor 31 is formed at the lower end portion of the rotor 32. With this configuration, the rotational force of the motor 31 is transmitted to the rotor 32, and the rotor 32 rotates around the shaft 35. Reference numeral 48 is a spacer that is in sliding contact with the lower surface of the rotor 32 and holds the space between the chassis 30 and the rotor 32.

A socket 39 is provided at the tip of the shaft 35 for accommodating and holding the light source 22, and for supplying electric power from a lead wire 38 passing through the shaft 35 to the light source 22. The mounting panel 27 is formed with a mounting hole 40 for inserting the protrusion 29. The protrusion 29 that has passed through the mounting hole 40 has a donut-shaped mounting member 4 from the other surface 27b side of the mounting panel 27.
