SOLUTION: The structure comprising adapting an approximately horseshoe- shaped sliding member provided with a recess at the flank of the front end of the temple and provided with barrels at the two free ends in such a manner that the sliding member is slidably and snugly housed into the recess of the temple so as to project both the barrels to the front inner side from the joint of the temple, providing about the middle of the joint in the recess of the temple with a projection acting as a spring stopper, housing a coil spring between the hollow segment between the parallel sides of the horseshoe shape and the spring stopper, screwing a cover into the recess of the temple and connecting the wraparound endpiece side barrels and the barrels at both ends of the horseshoe shape rotationally movably by means of screws is provided.
