The lens 3 is constituted of a main lens part 30 and an auxiliary lens part 31. The drive member 5 positions the light control member 4 to a first position and a second position so as to be movable and switchable. A focus F40U at an upper-side portion 40U being an optical axis Z side of the main lens part 30 when the light control member 4 is positioned in the first position is displaced to a lower side with respect to a focus F40D of a lower-side portion 40D.
