PROBLEM TO BE SOLVED: To implement the centering of a lens of spectacles of various shapes with excellent accuracy. SOLUTION: Five guide parts 7a-7e comprising long holes around a center of a lens placement plate 3 for placing a non-worked spectacles lens 2 thereon (a centering position S) are formed. Lens pressing members 8a-8e are slidably passed through these guide parts 7a-7e, and urged by a helical tension spring 16 in the lens pressing direction. The lens pressing members 8a-8e are moved along the guide parts 7a-7e by the force of the helical tension spring 16 to press and move the spectacles lens for centering.
