Abstract: A driving element includes: a base; a movable part spaced apart from the base in a direction parallel to a rotation axis; a connection part connecting the base and the movable part; a pair of first arm parts extending in a first direction parallel to the rotation axis with the rotation axis located therebetween; a pair of second arm parts extending in a second direction opposite to the first direction, with the rotation axis located therebetween; a coupling part coupling the pair of first arm parts and the pair of second arm parts to the connection part; and a piezoelectric driver disposed on at least either the pair of first arm parts or the pair of second arm parts.

Abstract: A drive element includes: a movable part; a first support part extending along a rotation axis of the movable part and connected at one end thereof to the movable part; a pair of arm parts placed with the rotation axis located therebetween; a pair of coupling parts coupling the pair of arm parts to another end of the first support part; a second support part extending along the rotation axis and supporting the pair of coupling parts; a fixation part to which the second support part is connected; and drive parts configured to drive the arm parts, respectively. The second support part has higher rigidity than the first support part, and the pair of coupling parts are placed so as to be inclined toward the movable part side. An angle between each coupling part and the second support part is greater than 90° and equal to or less than 135°.

Abstract: A light deflector includes: a drive element configured to rotate a movable part having a reflection surface, about a rotation axis; an upper lid superposed on an upper surface of the drive element; and a lower lid superposed on a lower surface of the drive element. The upper lid and the lower lid oppose the upper surface and the lower surface of the drive element, respectively, with gaps that permit specified rotational movement of the movable part.
