PROBLEM TO BE SOLVED: To perform an aligning operation in a state where a lens inserted in a lens barrel can be quickly and accurately moved in an optional direction, and to perform even UV adhesion in such a state. SOLUTION: In a lens aligning device 1, a lens barrel 10 into which a lens 11 is inserted is fit in the recessed part 4 of a pedestal 3, and a weighting member 20 is placed on the lens barrel 10. Then, the edge part 37 of a piston 33 is slid downward along an axial line so as to guide a pressing bar 39 to a hole 26, and the bar 39 is energized by the air pressure of the piston 33 so as to press the member 20 with a specified load. Thereafter, the aligning operation is performed by applying voltage to a piezoelectric element 35 and vibrating any of a plurality of center locating actuators 34 so that the member 20 is moved in an optional direction. When the aligning operation is finished, a UV curing type adhesive is dripped from the through-hole of the member 20 and is irradiated with UV light for a specified period of time by using a UV irradiation device 60, whereby the lens and the lens barrel are bonded and fixed.
