摘要： A drive device (300) includes an actuator (320x, 320y), a fixed member (301, 302), a movable member (311x, 311y), rotating members (337x, 338x, 337y, 338y), and a guide member (305x, 334x, 305y, 334y). The actuator is arranged on the fixed member (301, 302), and includes a piezoelectric element (323x, 323y) and at least two drivers (321x, 322x, 321y, 322y) on the piezoelectric element (323x, 323y) in parallel with the central axis of the piezoelectric element (323x, 323y). The movable member (311x, 311y) moves by the drivers (321x, 322x, 321y, 322y) on the fixed member (301, 302). The rotating members (337x, 338x, 337y, 338y) are located between the fixed member (301, 302) and the movable member (311x, 311y) to support the movable member (311x, 311y). The guide member (305x, 334x, 305y, 334y) is arranged on at least one of the fixed member (301, 302) and the movable member (311x, 311y), and guides movement of the rotating members (337x, 338x, 337y, 338y) in a direction parallel to the central axis of the piezoelectric element (323x, 323y). The drivers are located between the rotating members (337x, 338x, 337y, 338y) in the direction parallel to the central axis of the piezoelectric element (323x, 323y).
