Claims

[Scope of Claim for Utility Model Registration] (1) Both ends of the folded pieces of a wide thin spring plate folded back in a substantially U-shape are used to grip and hold a bundle of laminated sheets inserted between them. It has a main body in which a large number of biting claws are formed facing each other for the purpose of
One of the folded pieces of the main body has a concave strip formed on the outside extending across both ends in the width direction, and the other folded piece has a pressing bar on one side of both ends in the width direction. A support side piece is provided, and a groove side piece having a plurality of grooves for engaging the presser bar is provided on the other side, and further, one end is fitted to the presser bar support piece and the other end is engageable with the groove piece. 1. A binding tool for laminated sheets, characterized in that a presser bar made of spring steel is formed to be snap-fittable to the strip. (2) The binding tool for laminated sheets according to claim 1, wherein the main body has a notch for reducing bending rigidity in the U-shaped folded portion.
