This invention relates to a hinge structure in a frame of spectacles, wherein a bearing member having a pair of shaft insertion portions is mounted to a lens frame, a bifurcate member having shaft portions is fixed to an end of a temple to be in parallel with the temple, the shaft portions are respectively inserted into the shaft insertion portions such that the bifurcate member is horizontally movable, and a release prevention member is interposed inside the bifurcate member. Even if an external force is applied to a distal end of the bifurcate member, the bifurcate member is never released from the bearing portion, and smooth opening and closing functions of the temple may be guaranteed for a long period of time.
