Abstract
A light deflecting device which suppresses a vibration caused by swing of a light deflecting unit and transmitted to a fixed unit and prevents noise from being made on a housing to which the fixed unit is attached, including a light deflecting unit having paired beams on both sides of a movable unit having a light reflecting unit and a coil, and a fixed unit to which the light deflecting unit is swingably fixed through the beams and which includes a magnetic field forming unit, swings the movable unit with the beams as torsional rotation axes by an electromagnetic force generated by a driving current flowing to the coil and a magnetic field formed by the magnetic field forming unit, and a counter swing member in the fixed unit to be swung in a reverse phase to the light deflecting unit so it is opposed to the light deflecting unit.
