ABSTRACT:
A method is provided for securely holding a spectacle lens. Without using screwing members such as a screw and a nut, and extra parts such as a bush, a cylindrical pin and a slip-off preventive pin, a spectacle lens can surely be held. A taper pin is provided projecting on a lens holding member for holding a spectacle lens, and a taper hole having approximately the same size as the taper pin is provided on the spectacle lens. The taper pin is directly press-fitted into the taper hole, thereby holding the spectacle lens by a press-contact between an inner circumferential surface of the taper hole and an outer circumferential surface of the taper pin. The taper pin is press-fitted in a thickness direction of the spectacle lens.
