2. Description of the Related Art FIG. 11 is a perspective view of an essential part showing an example of a conventional binding device. The binding device 1 includes a main body 2. The main body 2 is attached to the cover of the file. The main body 2 is provided with an annular binding rod 3 which can be opened and closed. When filing a paper such as a document, the user, as shown in FIG. 11, holds both sides of the binding rod 3 with both fingers and pulls it open to open it. There is also known a binding device in which a vertical lever, a flat lever, and an X-shaped metal fitting for opening the binding rod are provided so as to project at both ends in the longitudinal direction of the main body.

[0003]

However, as shown in FIG.
In the binding device 1 shown in (1), when the paper such as the document is stored, it is difficult to hold the binding rod 3 and it is difficult to open the binding rod 3. Further, in the standing lever type binding device, the standing levers provided at both ends in the longitudinal direction interfere with each other, so that it is impossible to store the paper having a length equal to or more than the entire length of the binding device. Further, since the flat lever type binding has a short lever and a force for opening the binding lever is applied to a point, a considerable force is required to open the binding lever. Further, in these lever-type binding devices, since the levers are provided near both ends in the longitudinal direction, the point at which the force for opening the binding lever acts is biased near both ends in the longitudinal direction of the binding device. It made it difficult to open the rod. Moreover, in the conventional binding device, in order to open the binding rod, it is inconvenient to operate the levers and the X metal fittings provided near both ends in the longitudinal direction of the main body with both hands. Further, the lever type and X metal fitting type binding devices have a problem that the shape and mechanism of each component are complicated, the number of components is large, and it takes time and cost to manufacture.

Therefore, an object of the present invention is to provide a binding device which can easily open the binding rod with one hand and which has a simple structure and is easy to manufacture.
