Claims

[Scope of Claim for Utility Model Registration] 1. An eyeglass frame in which a lens frame and a vine are slidably connected by a hinge, characterized in that a sleeve unit S having the following configuration is inserted and fixed in a sheath-like case provided in front of the vine. A device to prevent loosening of eyeglass frames. (A) A shaft rod, which has a pivot seat for the hinge piece on the vine side at one end, is inserted into a sleeve that has a partition wall drilled around the hole that the shaft rod should pass through, so that it can move forward and backward,
A sleeve unit S in which a compression coil spring is interposed between the shaft end protruding from the sleeve end and this partition wall, and a collar is provided at the shaft end to come into contact with the spring end. 2. The eyeglass frame loosening prevention device as set forth in claim 1 of the utility model registration claim, in which a sheath-like case configured as a separate part from the vine is fixed to the vine. 3. The eyeglass frame loosening prevention device according to claim 1, wherein the sheath-like case is integrally formed with the vine.
