Abstract
A hinge structure of a spectacle frame has bearings formed at the ends of end pieces provided outside a pair of lenses or outside the rims supporting the lenses, pivotally rotatable shafts at the tips of a pair of temples are pivotally rotatably connected with the bearings, a compressed elastic means, being provided around the pivotally rotatable shaft exposed in the recess between the flange and the support face, to give pressure to the bearing for keeping the sliding face of the temple in slidable contact with the sliding face of the bearing. The hinge structure of a spectacle frame overcomes the disadvantages of the conventional hinge structure; that is functionally excellent because of easy assembling, needlessness of complicated adjustment, and capability to keep the temple turning torque constant for a long time; and that is also excellent in appearance and design.
