A pivotal member 6 is fixed an end-piece 8 secured to an outer edge of each lens rim 2, and has an annular groove 7 formed integral with and around the outer periphery of pivotal member. An end of the end-piece 8 extends upwards along the pivotal member 6 so as to provide a stopper 9 for a temple 5. A front end of the temple is curved to form a C-shaped arcuate member 10 which rotatably engages with the annular groove 7 in the pivotal member 6. The stopper 9 on the retainer abuts against and stops the arcuate member when it has rotated a predetermined angular distance, such that a joint for attaching eyeglass temples does not need any minute hinge bolts and can be of any shape to improve its ornamental value.
