Patent ID: 8830551

Claim:
An actuator comprising: a frame element; a pair of beam elements with first ends connected to the frame element; a movable element rotatably supported by the frame element via the beam elements, second ends of the beam elements being connected to the movable element; a driver configured to rotate the movable element relative to the frame element around the beam elements as a rotary shaft such that the beam elements rotate about a rotary axis; and damper elements provided on the beam elements between the first and second ends thereof and extending along the rotary axis, wherein the beam elements are formed in a meander shape and include turnback portions, straight portions, a first connecting shaft connected with the frame element, and a second connecting shaft connected with the movable element, wherein the damper elements are disposed on a straight line connecting the first and second connecting shafts as the rotary axis to connect discontinuous spaces of the meander beam elements, and wherein the discontinuous spaces between the straight portions of the meander beam element are connected on the rotary axis by the damper element.
