PROBLEM TO BE SOLVED: To provide an optical element displacement device, a lens-barrel using the device, and an imaging device that can reduce hollowing force generated by separation between a power point and a point of action.SOLUTION: The optical element displacement device includes: a first member holding an optical element and pins for moving the optical element; a second member with a direct-advance introducing groove in engagement with the pins; and a third member transmitting a rotation force from a driving source and driving the first member along the groove, the third member having a long hole in engagement with at least one of the pins as a driving pin, and displaces the optical element in a plane intersecting with an optical path of the optical element. |
