PURPOSE:To bring temples into contact with a face and obtain a sense of stability all the time by forming a groove in the rear end surface of an endpiece while increasing the depth outward and providing an engagement plate which engages the groove atop of each temple. CONSTITUTION:The groove 3 which increases in depth outward graudally is formed in the rear end surface 2 of each endpiece 1. Then, the engagement plate 4 which is fitted in the groove 3 is provided to the internal surface of the tip of the temple 5. Then, the engagement plate 3 is fitted in the groove 3, the inward terminal of the engagement plate 4 is fitted rotatably with a screw 10, etc., and the inward terminal of a leaf spring 6 is fixed to the bottom of the screw 3 so that the engagement plate 4 is pressed against the front end surface by the leaf spring 6. Consequently, the end surface of the engagement plate 4 fitted atop of the temple is presses by the leaf spring 6, but comes into contact with the face, so the sense of stability is obtained. |
