Abstract:
(EN) Provided is a rotation device comprising a first piezoelectric element 20 that deforms a first elastic deformation part 12 of a folded elastic deformation part , and a second piezoelectric element 21 that deforms a second elastic deformation part 13 of the folded elastic deformation part , the rotation device deforming the first elastic deformation part and the second elastic deformation part by applying a first drive voltage signal Va and a second drive voltage signal Vb, which are mutually different, to the first piezoelectric element and the second piezoelectric element, respectively, so as to rotate a movable part about a predetermined rotation axis, wherein the relationship between a connection position 113 in the first piezoelectric element where a signal line 111 of the first drive voltage signal Va and the first piezoelectric element are connected and a connection position 116 in the second piezoelectric element where a signal line 115 of the second drive voltage signal Vb and the second piezoelectric element are connected is a relatively identical or symmetrical relationship across the entire folded structure.
