Light deflector, deflecting device, distance-measuring apparatus, image projection device, and vehicle

A light deflector, comprising:

• a reflector having a reflecting surface;
• a first movable unit coupled to the reflector;
• a second movable unit coupled to the reflector, the reflector disposed between the first movable unit and the second movable unit;
• a first piezoelectric element disposed on the first movable unit, the first piezoelectric element configured to deform the first movable unit;
• a second piezoelectric element disposed on the second movable unit, the second piezoelectric element configured to deform the second movable unit;
• a first supporting part coupled to the first movable unit;
• a second supporting part coupled to the second movable unit;
• an input part disposed on the first supporting part, the input part configured to receive a voltage to be applied to at least the second piezoelectric element;
• and
• a wire electrically connecting the second piezoelectric element and the input part through the reflector, the wire configured to transmit the voltage received by the input part, to the second piezoelectric element, wherein
• the reflector is between the first movable unit and the second movable unit along a first axis,
• a passage area is provided through which light reflected by the reflector passes,
• the passage area extends along the first axis between the first supporting part and the second supporting part,
• the passage area is disposed on each side of the reflector in a direction intersecting the first axis on a same plane as the reflecting surface, and
• the passage area separates the first supporting part and the second supporting part in the direction intersecting the first axis on the same plane as the reflecting surface,
• the wire is disposed on the reflector and between the passage area and the reflecting surface,
• each of the first supporting part and the second supporting part has a first end and a second end disposed along the first axis such that both the first supporting part and the second supporting part extend along the first axis,
• the first end of the first supporting part faces the first end of the second supporting part across the passage area, and
• the second end of the first supporting part faces the second end of the second supporting part across the passage area.
