Abstract: An optical device actuator comprises a movable frame (33) including a focus lens (L11); a main shaft guide (40); a piezoelectric element (36a); a weight (36b); a fixed frame (30); a guide holding frame (35); and a spring (36c). The piezoelectric element (36a) imparts vibration to a first end (40a) side of the main shaft guide (40). The fixed frame (30) supports the piezoelectric element (36a) and the weight (36b) disposed on the first end (40a) side of the main shaft guide (40). The guide holding frame (35) supports, in a fixed state, the main shaft guide (40) on a second end (40b) side on the opposite side from the first end (40a) side. The spring (36c) is provided on the first end (40a) side of the main shaft guide (40), and presses the piezoelectric element (36a) along the axial direction with respect to the first end (40a) of the main shaft guide (40) via the weight (36b).
