Such personal portable terminals are generally bar-type personal portable terminals, flip-type personal portable terminals, folder-type personal portable terminals, and slide-type personal portable terminals according to appearance or operation. -type). In addition, recently, a tilting personal portable terminal has been proposed in which the second body can be tilted with respect to the first body at a predetermined angle.

In addition, a terminal in which a second main body is opened and closed in a rotational manner with respect to the first main body, such as a folding personal portable terminal and a tilting personal portable terminal, generally has an opening and closing operation of the second main body with respect to the first main body. It is configured to be done in a semi-automatic manner. In general, the existing hinge module includes a drive cam member, a driven cam member provided to be accessible and spaced apart from the drive cam member to interact with the drive cam member, and an elastic member elastically supporting the driven cam member. Modularly provided therein, and is mounted on a conventional rotary opening and closing personal portable terminal to provide the opening and closing force so that the opening and closing of the second body to the first body is made in a semi-automatic manner.

However, conventionally, there is a problem in that allophones are generated in the hinge module during the opening and closing operation. In particular, a phenomenon in which the driven cam is twisted with respect to the housing during the operation of the hinge module, and there is a problem that the operation joint is generated by the friction between the driven cam and the housing as the torsion occurs in the driven cam.

On the other hand, the existing hinge module has a limit in providing a more than a certain opening force due to its structural characteristics, when the size and weight of the main body to which the opening and closing force is applied more than a certain number is used by connecting a plurality of hinge modules in series. For example, conventionally, the first hinge module is connected to one side of the hinge bushing provided at the connection portion where the first body and the second body are connected, and the second hinge module is arranged in series with the first hinge module at the other side of the hinge bushing. The structure connecting the hinge module has been presented.

However, in the related art, since it is difficult to closely contact the hinge portion between the hinge portion of the main body and each hinge module, there is a problem in that allophones are generated in the hinge module during the opening and closing operation. In particular, since each hinge module is difficult to be formed to have a very precise dimensional accuracy in reality, according to the dimensional error of each hinge module, a separate part must be inserted to improve the joint between the hinge bushing and the hinge module.
