Abstract
A binding device for files and binders includes rings to be inserted into binding holes of an object to be bound which are openably and closeably secured to a base plate so as to be opened and closed by an opening-closing mechanism including a rotationally movable lever. In the binding device, a first ring member and a second ring member defining the binding rings are configured such that they are interlocked with the opening-closing mechanism including the lever so as to be opened and closed about respective pivot portions provided in the lower end thereof by rotationally moving the lever. The base plate is provided with a lever shaft receiver for pivotally supporting the lever of the opening-closing mechanism, and the lever shaft receiver is formed by punching the base plate and bending the punched portion upwardly.
