PURPOSE:To move an object lens in any of three directions orthogonal to one another in parallel without inclination by guiding a lens barrel in long holes orthogonal to each other in accordance with the driving direction. CONSTITUTION:When power is supplied to a Z-direction driving coil 3, a lens barrel 2 is moved while sliding inside faces of y-direction guide members 11-1 and 11-2 and an x-direction guide member 21. Long hole parts 12-1 and 12-2 of y-direction guide members and a long hole part 22 of the x-direction guide member are orthogonal to each other to control movement of the lens barrel 2 in (x) and (y) directions, and the barrel 2 is moved in parallel only in the Z direction. When power is supplied to x-direction driving coils 15-1 and 15-2, one of them attrats an x-direction driving magnet 13, and the other repels it, and y- direction guide members 11-1 and 11-2 are moved in the (x) direction by actions of x-direction parallel flat springs 14-1-14-4. The barrel 2 is moved in parallel in the (x) direction together with y-direction guide members 11-1 and 11-2 without inclination. Similarly, the barrel 2 is moved in parallel in the (y) direction together with the x-direction guide member 21.
