PURPOSE: An eyeglasses structure is provided to obtain stable folding and unfolding of temples relative to a frame because the temples can rotate clockwise and counterclockwise within an angle limit through hinges. CONSTITUTION: An eyeglasses frame(10) comprises an upper frame(11) and a lower frame(12). An end of the upper frame and an end of the lower frame are overlapped with each other. A hinge(20) has a hinge axis(22), a base plate(21) which is coupled with a fixing bolt(51) in the center thereof, and a stopper(23) which is protruded in the same direction as the hinge axis beside the hinge axis. A rotating control plate is formed in a disk shape corresponding to the base plate of the hinge and has a hinge axis hole and a stopper hole which the hinge axis and the stopper respectively pass through. A temple(40) has a through hole for insertion of the hinge axis and a free motion space on the concentric circle of the through hole to allow for free motion of the stopper.
