PROBLEM TO BE SOLVED: To provide a forward inclination angle adjusting mechanism of a front frame of spectacles, in which the mechanism is applicable even to wrap endpieces using a plastically undeformable rigid material, the changing of the adjusted angle with lapse of time does not occur and the structure is extremely simple. SOLUTION: Either one of the front and back surfaces of in a connection section 21 of the wrap endpieces 2 is fixed in plane to each of projecting parts 11/11 formed by extending to both ends of the front frame 1, and in the meanwhile, a plurality of kinds of the wrap endpieces 2/2, etc., varying in the forward inclination angles with respect to the vertical planes of the front and back surfaces of the connection section 21 are kept prepared, and the forward inclination angle of the front frame 1 is made adjustable by the attachment and detachment exchange of the wrap endpiece 2 selected from these wrap endpieces.
