PROBLEM TO BE SOLVED: To provide a flip-up spectacle frame capable of flipping up a flip-up front part with an extremely simple mechanism. SOLUTION: A shaft 15 is provided on the center of a front frame 2, a clamping part 8 is provided on the center of the flip-up front part 1, the shaft 15 is clamped by the clamping part 8 and screwed, to thereby add a friction resistance to rotation of the clamping part 8, and thereby the flip-up front part 1 which is flipped up can be held without being lowered.
