Abstract
A light deflecting element includes: a movable plate provided with a light reflecting section having light reflectivity; a support section; a coupling section adapted to couple the movable plate rotatably to the support section; and a magnet disposed on an opposite surface of the movable plate to the light reflecting section, wherein the coupling section has a shape having a width gradually increasing in a direction from a side of the light reflecting section toward a side of the magnet in a cross-sectional view perpendicular to a rotational axis of the movable plate.

A light deflecting element comprising:
- a movable plate provided with a light reflecting section having light reflectivity;
- a support section;
- a coupling section adapted to couple the movable plate rotatably to the support section, and composed mainly of a plurality of beams parallel to each other;
- and
- a magnet disposed on an opposite surface of the movable plate to the light reflecting section,
- wherein the plurality of beams of the coupling section is arranged side-by-side in a direction parallel to the light reflecting section and has a shape having a total length of widths of the respective beams and distances between adjacent ones of the beams in the direction parallel to the light reflecting section gradually increasing in a direction from a side of the light reflecting section toward a side of the magnet in a cross-sectional view perpendicular to a rotational axis of the movable plate.
