Claims

[Scope of utility model registration request]

A rotating board is rotatably fixed to a fixed board that is fixed to the cover, and a pair of substantially arc-shaped ring pieces that form a ring by locking their tips to each other are attached to the fixed board and the rotating board, respectively. In the resin ring binder that is protruded, a hinge ring is formed at the fixed part of the fixed board and the rotary board with appropriate openings in the upper and lower directions, and one of the pair of ring pieces is engaged. A locking hole is provided with a locking protrusion on the other side to lock the locking hole, and two sets of rings are formed at four places and two sets are provided from one end, and one set of rings is used to lock the fixed board or the rotating board. The above-mentioned locking is released by narrowing one of the ring pieces on the side to the side facing each other, and at the same time, the ring piece protruding from the base plate on the opposite side to the above-mentioned set ring is released using the other set ring. A ring binder characterized in that the rings are narrowed toward opposite sides and are expanded by rotating a rotating base plate.
