To prevent a clearance between the armor of a spectacle frame and a lens and a clearance between a bridge and the lens from producing by preventing screws from loosening.

Bolts 5 are inserted between the armor 10 of the spectacle frame and the lens 7 and between the bridge 12 and the lens 7, and nuts 6 are threaded to the screw parts of the bolts 5 projected from the lens 7. Washers 1 having projections 3 on the front and rear surfaces thereof are installed between the armor 10 and the lens 7, between the lens 7 and the nut 6, between the bridge 12 and the lens 7, and between the lens 7 and the nut 6. When the nuts 6 are tightened, the projections 3 of the washers 1 are crimped into the mating parts opposed thereto to stop the relative movement of the armor 10 to the lens, the lens 7 to the nut 6, the bridge 12 to the lens 7, and the lens 7 to the nut 6. Thus the looseness of the screws can be stopped.
