Eyeglasses frame and method for assembling/manufacturing same, structure for fixing eyeglasses lenses

In an eyeglasses to which the invention is applied, a taper nut having a collar portion and a conical taper portion is fitted and attached to a hole having a circular truncated cone shape and pierced in an eyeglasses part. A hole for passing a male screw therethrough is formed in another eyeglasses part, and the eyeglasses parts are connected to each other by screwing the male screw inserted to the hole with a female screw provided in an inner portion of the taper nut. Further, continuous holes having a circular truncated cone shape are pierced in both the connected eyeglasses parts. It is possible to prevent both the eyeglasses parts from rotating with each other by fitting the taper nut to the hole, and both the parts are connected by engaging the male screw from a side in which the taper of the taper nut is reduced.
