ROTATING BODY ANGLE HOLDING MECHANISM, AND FLIP-UP GLASSES

PROBLEM TO BE SOLVED: To provide flip-up glasses whose glasses and flip-up components can be exchanged with two screws by stably holding flip-up angles at 60 degrees and 120 degrees, using a flip-up mechanism to be manufactured by simple production and assembling. SOLUTION: The flip-up glasses are fixed with mounting screws through holes of glass rear frames in screw holes of hexagonal post-like bodies 2 mounted on rectangular shape pieces which has been cut and bent, on glass front frames in a zigzag manner. When upward rotational force is applied to the glass front frames, the glass front frames are flipped up with elastic force around a rotational center shaft so as to be stably held at 60 degrees. When rotational force is further applied to the glass front frames, the glass front frames are stably held at 120 degrees. When downward rotational force is further applied to the glass frame, the frames are rotated from 120 to 60 degrees, and from 60 to 0 degrees. In addition, when the hexagonal post-like body is exchanged, the mounting screws are removed and the hexagonal post-like body is easily exchanged by moving the hexagonal post-like body in a direction of a side face to be removed.
