摘要

A binding device for files and binders includes rings to be inserted into binding holes of objects to be bound can be opened sufficiently, in which a lever of an opening-closing mechanism for the rings can be operated sufficiently, and which can be attached to the cover of files and binders. This binding device for files and binders is a binding device in which rings 612 to be inserted into binding holes of an object to be bound which are openably and closeably secured to a base plate 618 so as to be opened and closed by an opening-closing mechanism 616 including a rotationally movable lever 614. In the binding device, a first ring member 620 and a second ring member 640 defining the binding rings 612 are configured such that they are interlocked with the opening-closing mechanism 616 including the lever 614 so as to be opened and closed about respective pivot portions 646 and 650 provided in the lower end thereof by rotationally moving the lever 614. The base plate 618 is provided with a lever shaft receiver 670 for pivotally supporting the lever 614 of the opening-closing mechanism 616, and the lever shaft receiver 670 is formed by punching the base plate 618 and bending the punched portion upwardly.
