Claims

[Scope of utility model registration request]

A pair of substantially arc-shaped ring pieces that form a ring by rotatably fixing a rotating board to a fixed board that is fixed to the cover, and locking their tips to the fixed board and the rotating board, respectively. A ring piece of at least one of the fixed base plate or the rotary base plate is integrally formed with the base plate, and the elasticity of the material of the ring piece and the base plate allows the ring piece to be approximately perpendicular to the other ring piece in the opening/closing direction of the ring. A ring binder characterized by being able to be displaced by a required amount in a certain direction.
