PURPOSE: The connection structure of the temples of a pair of glasses is provided to prevent shaking due to a gap even if being used for a long time. CONSTITUTION: The both sides of an eyeglasses frame(10) are extended to the back to be bent. An extension part(11) connects temples on a pair of glasses(20). Arm protrusions(12a,12b) have rotational holes(13a,13b). The arm protrusions are placed at a fixed interval and are projected to the inner side in the top and lower part. A rotational pin(21) is inserted into the inner side of the extension part to be rotated.
