A light adjusting apparatus (1) including a drive section (2) provided with an axial magnet (11), a coil core member (12) and a coil (13), a first substrate (3) provided with a light passage opening (3c) and a first cut-out portion (3d) for inserting the axial magnet (11), on one side of which the coil (13) and the coil core member (12) are arranged, a second substrate (4) provided with a light passage opening (4c) and a second cut-out portion (4d) for inserting the axial magnet (11), located at a predetermined distance from the first substrate (3), an incident light adjusting section (6) to which the axial magnet (11) is joined, and an axial magnet support member (21) provided with a distance keeping portion (21b) that keeps a distance between the coil core member (12) and the axial magnet (11) to within a certain range and a dropout prevention portion (21c) that prevents dropout of the axial magnet (11) from the first cut-out portion (3d), the axial magnet support member (21) being fixed to the coil core member (12), in which the incident light adjusting section (6) is rotated by the drive section (2) to be displaced to a retracted position and an inserted position to thereby adjust the incident light. |
