Generally, glasses are used to prevent vision recovery or vision loss in a person with reduced vision or to protect the eyes from strong ultraviolet rays. Moreover, in recent years, a lot of people are using it as a part of fashion.

The spectacles include a rim having a pair of lens fasteners for fixing the lens, and a leg assembled at both ends of the rim to be mounted on the user's ear wheels.

In addition, the spectacle frame is made of various materials such as metal plastic, wood, etc. Recently, a thin metal spectacle frame including a front of a metal thin plate (product name: Wagner), such as stainless steel thin plate has been made, the metal sheet The spectacle frame has an advantage of being light and flexible.

By the way, conventionally, such as the Republic of Korea Utility Model Publication No. 2012-0000933, there is shown a spectacle frame integrally molded through a metal sheet the entire front including the rim and bridge.

However, the spectacle frame of which the front is entirely made of a thin metal plate is excessively twisted in the bridge part, which is difficult to have form stability, and thus, may cause a decrease in durability or wearing comfort.

In addition, the hinge connection of the front and the leg through the hinge connector is usually formed by penetrating and fastening the hinge bolt between the hinge connector of the upper and lower ends and the hinge piece of the leg, and the hinge connection structure is the hinge piece and the hinge of the leg. Direct friction between the bolts occurs.

Therefore, the fastening state of the hinge bolts is poor due to the direct friction between the hinge pieces of the legs and the hinge bolts, and users have to point out the hassle of compensating the fastening state of the bad hinge bolts by visiting the optician periodically.

Therefore, even in this field, in order to solve the general problems caused by the hinge connection structure, the hinge pipe and the inner side of the hinge piece of the inner side of the hinge bolt is installed, the hinge piece of the hinge rotating bridge around the hinge bolt and the hinge bolt It prevents direct friction between them and suppresses loosening of the hinge bolts.

However, since the hinge connecting structure has to insert the small diameter of the rotating tube into the hinge piece of the leg and then reinsert the hinge piece of the leg into which the rotating tube is inserted into the hinge connector, the small size of the rotating tube in this process It can be separated from the hinge piece has a problem of low productivity.

In addition, play is inevitably generated between the hinge tube and the hinge piece of the tube and between the hinge bolt and the tube, it is difficult to secure the normal hinge connection state of the bridge by this play.
