Abstract
A drive module includes: a cylindrical or columnar driven body 4; a cylindrical supporting body 5 for containing the driven body therein; flat spring members 6, 7 for elastically holding the driven body movably along a certain direction with respect to the supporting body; and a drive means 10 for driving the driven body against a restoring force of the flat spring members, in which the spring constant of the side of the flat spring members on which a force generated by the drive means acts is larger than that of the opposite side on which the force generated by the drive means acts through the driven body.
