Claims

[Scope of utility model registration request]

Rotatably relative to the fixed board fixed to the cover 2
A so-called resin-made ring consisting of a pair of substantially arc-shaped ring pieces protruding from three locations, which form a ring by fixing two rotating boards and locking their tips to the fixed board and the rotating board, respectively. In a three-hole ring binder, a hinge ring is formed in which the fixing portion of the fixed substrate and the rotary substrate are provided with appropriate openings in the upper and lower directions, and a locking hole is formed in one of the pair of ring pieces in the other. A locking protrusion is provided for locking, and one rotating board is fixed to the fixed board with a ring piece at one location so as to be rotatable only;
The other rotary base plate is provided with ring pieces at two locations and is fixed with a spring interposed so as to slide appropriately, and the two opposing ring pieces of the two rotary bases are narrowed inward to close the above three locations. A three-hole ring binder characterized in that the ring is configured such that the ring expands when the locked state of the ring is released.
