Abstract: Provided is a piezoelectric actuator, a linear driving device, and an electronic device that achieve displacement of a drive shaft of a given magnitude even in a case where a low voltage is applied. A piezoelectric actuator includes a piezoelectric material composed of a stack of plate-shaped piezoelectric elements, the piezoelectric material being expandable and contractable in a direction of a plate surface thereof; an elastic plate having the piezoelectric material formed on a plate surface of the elastic plate, and a drive shaft having one end fixed to either the piezoelectric material or the elastic plate in a direction perpendicular to the plate surface of the piezoelectric material.

Abstract: Provided are a piezoelectric driving device, an optical member driving device, a camera device, and an electronic apparatus, which are capable of performing driving only by one-direction oscillation modes, and capable of combining the oscillation modes to enable driving in two directions. A piezoelectric driving device (10) includes: a driving portion (12) to be brought into frictional contact with an object to be driven; and two piezoelectric portions (14a, 14b) (14c, 14d), which are provided to the driving portion (12), are arranged on a plane with the driving portion (12) being sandwiched between the two piezoelectric portions, and are configured to be bent with respect to the plane when voltages are applied thereto. Further, a piezoelectric driving device (10) includes: a driving portion (12) to be brought into frictional contact with an object to be driven; and at least four piezoelectric portions (14a to 14d), which are fixed to the driving portion (12), are arranged in a circulated manner on a plane and around the driving portion (12), and are configured to be bent with respect to the plane when voltages are applied thereto.

Abstract: A lens driving device includes a first movable lens holding portion that holds a first movable lens body, a second movable lens holding portion that holds a second movable lens body heavier than the first movable lens body, a first driving shaft that drives the first movable lens holding portion and a second driving shaft that drives the second movable lens holding portion, and a first guide shaft and a second guide shaft thicker than the first guide shaft. The first and second guide shafts are arranged in parallel with the first driving shaft and the second driving shaft. Loads of the first movable lens holding portion and the second movable lens holding portion are respectively and independently supported and guided by one of the first and second guide shafts, and rotation is prevented by the other of the first and second guide shafts.
