Claim 2:
3. The eyeglass frame according to claim 1, wherein the rotational protrusion (6) includes:
a rotational gap (61) which is formed at the inner end of the rotational protrusion (6) and gets in contact with the rear surface of the connection plate (4) to be inserted into the rotation space (55) through the opening (54) between the support protrusion (52) and the latch hook (53) of the rotational support (5) when both sides of the connection plate (4) are bent forward, thereby rotating inside the rotation space (55) when the rims (2) are folded rearward; and
a latch hole (62) which is formed to allow the front end of the latch hook (53) to enter when the rotational gap (61) penetrates back and forth from the outside and the rotational gap (61) enters the rotational space (55), and to allow the tip of the latch hook (53) to be caught while penetrating through the latch hole (62) when the rims (2) are folded rearward.
