PROBLEM TO BE SOLVED: To provide a drive unit for the movable part of an optical device, which secures rectilinear property in movement with compact and simple constitution. SOLUTION: The drive unit for the movable part of the optical device includes: a driving part for driving the movable part; a driving force transmitting part for transmitting driving force of the driving part to the movable part; and a guiding part for linearly moving the driving force transmitting part. The guiding part includes an elastic part in an energizing state acting in a direction perpendicular to the moving direction on a line so that the driving force transmitting part moves on the line.
