PROBLEM TO BE SOLVED: To provide a flip-up mechanism of a simple configuration, using a magnet.SOLUTION: The flip-up mechanism of spectacle frames freely flipping up a spectacle lens 24 to a prescribed flip-up position, includes a first magnetic body 312 provided at a frame body 13 side; and a square second magnetic body 313 that is provided at a spectacle lens 24 side and attracted to the first magnetic body 312. The first magnetic body 312 includes a rolling surface 312a for rolling the second magnetic body 312, while retaining the attracted state to the second magnetic body 313. The second magnetic body 313 is rolled on the rolling surface 312a so as to rotationally turn the spectacle lens 24 to the frame body 13. At least one of the first magnetic body 312 and the second magnetic body 313 may be buried in the lens 24 or the frame 13. |
