Abstract
A light adjusting apparatus includes a substrate, a rotating shaft member made of an axial magnet, a light adjusting section rotatably integrated with the rotating shaft member and an electromagnetic drive source rotating the rotating shaft member using a coil core member made of a coil and a magnetic body, the light adjusting apparatus being configured to adjust light by displacing the light adjusting section to a retracted position and an inserted position, and a rotatable range θa is set to have a portion overlapping at least one of a range θn in which a direction of torque acting on the rotating shaft member when no current is flowing through the coil becomes a negative direction and a range θp in which the direction of torque becomes a positive direction, and a range θ1 where θa overlaps θn and a range θ2 where θa overlaps θp have different widths.
