Abstract
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, and with a simple structure, the spectacle lens can surely be held. A taper pin 21 is provided projecting on a lens holding member (endpiece 4 and bridge 5) for holding a spectacle lens 10, and a taper hole 11 having approximately the same size as the taper pin is provided on the spectacle lens, and the taper pin is directly press-fitted into the taper hole, thereby surely 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 10.
