Claims

[Scope of utility model registration request]

a cylindrical threaded portion with a threaded diameter _d1 ;
A male thread ₁ consisting of an inverted truncated conical tapered part having a bottom diameter equal to _d1 and a top diameter _d2 larger than d1, and a disc-shaped head part having a diameter _d3 larger than _d2 , and the threaded part a first member 3 consisting of a female screw 2 having a screw hole portion into which the screw portion is screwed; a cylindrical blank hole portion into which the screw portion fits, and a disc-shaped counterbore portion into which the head portion approximately fits; , the barreled surface of the head is in surface contact with the horizontal bottom surface of the counterbore, thereby generating a large rotational torque in the male screw 1, and the tapered portion is in contact with the horizontal bottom surface of the counterbore. A screw structure for an eyeglass frame, characterized in that a peripheral wall near the counterbore portion is elastically deformed to prevent a male screw 1 from loosening.
